Edit Step 1 Rear Panel  ¶ 

Image #1

Edit Step 1 Rear Panel  ¶ 

  • Before disassembling your iPhone, be sure it is powered off.

  • Remove the two 3.6 mm Pentalobe screws next to the dock connector.

  • During reassembly, we recommend you replace the 5-point screws with equivalent Phillips screws. Our Liberation Kit provides the tools and screws needed to replace the Pentalobe screws with Phillips screws.

  • The 5-Point Screwdriver should only be used once, as it has the potential to strip the screws.

Edit Step 2  ¶

Edit Step 2  ¶ 

  • Push the rear panel toward the top edge of the iPhone.

  • The panel will move about 2 mm.

Edit Step 3  ¶

Edit Step 4 Battery  ¶ 

  • Remove the following screws securing the battery connector to the logic board:

    • One 1.7 mm Phillips screw

    • One 1.5 mm Phillips screw.

  • Use a plastic opening tool to gently detach the battery connector from the socket on the device. Start lifting off the connector from the bottom side, by placing the tip of the tool between the loudspeaker enclosure and the metal cover of the connector.

  • The battery connector comes off vertically from the logic board. Do not apply force sideways.

  • Pay attention to the pressure contact underneath the top screw of the battery connector. This may come loose while prying the battery connector from its socket.

Edit Step 5  ¶ 

Image #1

Edit Step 5  ¶ 

  • Use a plastic opening tool to pull the pressure contact from underneath the battery connector.

  • When reinstalling the pressure contact, be sure to clean it with a degreaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to create wireless interference.

  • Take notice of the position of the small black ground clip on the upper screw of the battery connector. This clip is attached only by the upper screw. When reinstalling, it must be aligned so the gold contact point will press against the back cover.

  • Be careful not to rip off the battery connector socket soldered on the logic board. There are 4 very small soldering points awaiting this mistake!

Edit Step 6  ¶ 

Image #1

Edit Step 6  ¶ 

  • Insert the edge of a plastic opening tool between the battery and the outer case near the bottom of the iPhone.

  • Use the edge of a plastic opening tool to pry the rear camera connector up from its socket on the logic board.

  • Be careful not to break any components off the surrounding area on the logic board as you pry upwards.

  • Remove the rear camera from the iPhone.

  • There is a small rubber gasket that sits underneath the rear-facing camera. Make sure that it is properly seated before reassembly.

Edit Step 16 SIM Card  ¶ 

Image #1

Edit Step 16 SIM Card  ¶ 

  • Use a SIM card eject tool or a paperclip to eject the SIM card and its holder.

  • This may require a significant amount of force.

  • Remove the SIM card and its holder.

Edit Step 17 Logic Board  ¶ 

Image #1

Edit Step 17 Logic Board  ¶ 

  • Remove the five cables near the top of the logic board in the following order:

    • Headphone jack/volume button cable

    • Front facing camera cable

    • Digitizer cable

    • Display data cable

    • Power button cable (located underneath the headphone jack/volume button cable as shown in the second picture.)

  • To disconnect the cables, use the edge of a plastic opening tool to gently lift their connectors up and out of the sockets on the logic board.

  • Be careful not to break any of the small and delicate surface mount components as you disconnect the cables.

Edit Step 18  ¶

Edit Step 22  ¶ 

  • If present, peel the piece of black tape covering the hidden screw near the power button.

  • Remove the 2.6 mm Phillips screw securing the logic board near the power button.

    • (Use caution when removing this screw and removing the power contact held by it; the contact tab will come loose with the screw)

  • Notice the small rubber bumper under the screen & digitizer cables (which are detached at top above the Q-code). This bumper can fall off of the logic board when removed or get stuck to the cables and fall off later.

Edit Step 23  ¶ 

Image #1

Edit Step 23  ¶ 

  • Remove the following screws securing the logic board to the case:

    • One 2.5 mm Phillips screw near the vibrator motor

    • One 2.4 mm Phillips screw

    • One 3.6 mm standoff along the side of the logic board nearest the battery opening.

  • Use a small flathead screwdriver to remove the single 3.6 mm standoffscrew.

Edit Step 24  ¶ 

Image #1

Edit Step 24  ¶ 

  • Carefully lift the logic board from the end closest to the speaker enclosure and slide it away from the top edge of the iPhone.

  • Remove the logic board.

  • Before reassembly, be sure to clean all metal-to-metal contact points on the logic board (not the mating halves of connectors) with a de-greaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to cause grounding issues.

  • There is a small rubber bumper that sits on the top edge of the logic board where the digitizer and screen cables come through the case. It protects the cables as they bend over the top of the logic board. This can either get stuck to the cables or fall off the logic board when it comes out. Look back over step 22 for more details.

Edit Step 25  ¶ 

Image #1

Edit Step 25  ¶ 

  • Be sure not to lose the small grounding finger for the rear facing camera near the power button. This finger rests on top of the PCB, screwed down, and covered with the adhesive black plastic tape.

Image #1

Edit Step 28 Power Button  ¶ 

  • Remove the two 1.6 mm Phillips screws securing the power button bracket to the outer case.

    • Take extra care with the display cables, which can prevent easy access to the right-hand screw. The cables are easily damaged.

  • Slightly pull the power button bracket away from the outer case.

Edit Step 29  ¶ 

Image #1

Edit Step 29  ¶ 

  • Use a pair of tweezers to remove the power button from the iPhone.

  • During reassembly, take note of the correct orientation of the power button. The metal loop should be facing downwards and the outward edges should be on top.

Edit Step 30 Power and Sensor Cable Assembly  ¶

The #00 Phillips and 2.5 mm flat head screwdrivers that are suggested tools are too big. I needed to use a #000 Phillips and 5/64 in flat head screwdrivers.

Difficulty: MODERATE? Then why is the vibrator replacement guide DIFFICULT? I think these need to be switch around guys...

This repair will destroy your soul. I would not recommend even attempting it without even more specialized tools (eye loupe, headlamp, preternatural patience) as it is extraordinarily easy to ruin your phone with one quick misstep. I've thrown in the towel after weeks of attempting the job. After ripping the screen cable for the second and final time, I'm selling for parts.

mikemckinnon, · Reply

i did the repair, and my power button is now working, however the loudspeaker is now very pour and i have a lot of noise on then screen when i make a cal, the sensor is working fine, but when i move the phone and look at the screen it is going "crazy" what have i done wrong?

Henrik, · Reply

i replace my lcd and my power sensor backlights turn on but display doesn't show anything any solution????

Zadd, · Reply

I agree with comments made.

This is more than moderately difficult.

It is doable, but not if you have never done any repairs, have short patience, or don't have micro tools.

The parts are much smaller than older iPhones i've worked on. I could not have done it without head magnifiers. I have 40+ year old eyes, your eyes may be better.

A phillips 000 worked better for me throughout in place of 00 phillips.

Look very carefully at the actual replacement part before starting and try to understand how it folds and wraps around the earpiece. (the part from fixit comes flat- if you orient it with the round power switch toward with upper left, the rectangular piece in the center with a hole in it is where the earpiece is attached with sticky foam. The bottom right "leg" folds up and over the earpiece and attaches to a bracket above the earpiece, held down by a metal clip. The left "leg" is in approximately the right position but has 2 right angle bends in the final 3d configuration ending in a plane higher than when flat. The upper left "arm" folds up and wraps over the plastic power button bracket.)

The last steps made a lot more sense after I got this, but I had to disassemble it to understand and had torn one of the ribbon in the process, lucky I was replacing it anyways.

davisyang, · Reply

Difficulty: Moderate? This is a very involved tear down that took me quite a few hours. I have new respect for how it's made and won't do it again. I did kill half the digitizer, presume a broken cable and will sell it for parts.

paulverket, · Reply

A remarkable guide. Very precise with no surprises. Did the entire replacement without a hitch. Thanks!!

Anant, · Reply

Replaced this because the power button was slightly depressed, "spongy", required a lot of force to activate. Proximity sensor was also flaky. Since the repair I have the following issues:

1) Power button is still spongy, no audible/tactile "click" sound/sensation. Suspect the cable was not the cause of the original physical button issue (as others had suggested)

QUESTION: What should I look at next for the physical button issue? The bracket that holds the power button/cable against the outer casing seemed fine physically, but maybe not?

2) Power button is hyper sensitive, acts as if it's "stuck". When pressed once it acts as if it's held down. Tapping it very lightly will sometimes initiate a single press (i.e. lock the phone) 95% of the time it acts like it's held down (i.e. nothing happen then seconds later it shows the "slide to power off" screen).

QUESTION: Does this sound like a flaky connection issue, bad/damaged cable? What should I investigate?

Guys i have just did this repair for the very first time and this is very do able with these items:

Pro tech toolkit> https://www.ifixit.com/Store/Tools/Pro-T...

iPhone iScrew phone trays> https://www.ifixit.com/Store/Tools/iScre...

and of coarse your parts> https://www.ifixit.com/Store/iPhone/iPho...

The said instructions provided are spot on and fantastic. The protool kit has everything you need to work on small precision electronics as far as opening and disassembly tools. The iscrew trays are amazing and worth the 7 bucks to have every single screw organized and in place as you take them out of your phone. I was able to achieve the same results because I used the same tools that ifixit not only used but recommends and i followed every step to the T. The biggest issue you will face is working by feel on micro devices and having the patience to not damage anything. The guides are amazing.

Hi all !

I repaired my phone, the power button works normally again.

Pay attention if you plan to do it, it is not as simple as it seems, took me several hours and cost me a new battery connector !

Therefore, my phone is randomly rebooting every 30s to 3mn, don't know why. Impossible to find a solution to fix it. Maybe someone could help me ?

Guys, UV filter attached to ambient light sensor is very important to install. I got an aftermarket replacement for power and sensor cable and forgot to take foam UV filter from original part to replacement. So during the call (phone or Skype) screen didn't turn off.

After installing old UV filter all is working like a charm.

Ребята, фильтр наклееный на датчик освещенности крайне обязателен для установки. На купленном шлейфе кнопки питания и сенсора небыло этой пленки и функция отключения дисплея во время звонка не работала вообще. После установки фильтра (не что инное как полупрозрачная пленка) все работает как и положено.

Had local iPhone repair shop remove the screw. Repair complete!

nimpsy,

I left the battery in and everything above the middle, using a pen knife to flex the logic board, I had plenty of room to else the old out and the new in.

Worked well and saved a lot of time.

Keith M, · Reply

After reviewing the steps I decided to follow this guy's advice and left the battery in.....one less item to possibly foul up. I don't know if it made it any faster (first time to open my phone, so nothing to compare it to) but I can say that my phone is charging for the first time in 6 months :D

Jennifer,

BEFORE YOU START:

1) This is doable but not easy, quick or without risk.

2) If this is your 1st time, the whole process can take >2 hours (half of it reading this fixit manual and notes, which I highly recommend!)

3) I highly recommend placing a large, thin clean white cloth on the table. This prevents screws from rolling around and you will clearly see anything falling out.

4) If you have them, use tight surgical (latex) gloves. This prevents you from greasing up contacts.

5) Have e.g. a big old egg box ready, so you can place the screws in order (and maybe write step/screw size on the side).

6) I bought my display from "Generic" on Amazon ($20.36). Screen works fine and tools were ok but not great (screw drivers do not withstand force needed to unscrew some).

7) I had my own 2mm Phillips screw driver and a 2.4mm flat (for the big screws).

8) Have a nice cold beer by your side! Good luck!

Sounds like this comment relates to a screen replacement, not a rear panel replacement. No way a rear panel replacement would take 2 hours - can be done in 2 minutes!

Jonathan Deamer,

I was paranoid about stripping the pentalobes - I used the ifixit pentalobe screwdriver TOGETHER with a layer of Glad Wrap (cling film or saran wrap for the non-Aussies) over the pentalobe holes - absolutely no problems. Guess it helps the driver head gain purchase?

Anyway hat tip to this guy:

After seeing the comments about trouble finding the carrier, I shut down the phone, did a soft reset (by holding the power and home buttons until it started and then shut down and stayed off), and removed the SIM. After the repair, I replaced the SIM and plugged it in to the charger. It started up and found the carrier (Verizon, as it happens) immediately. I would guess that only the soft reset made a difference, but I did both.

I pried one end of the back off only to find 2 funny little screws holding the other end on so I took my Dremel, like Jack said, and ground those suckers out. Once I had the back off I loosened all the screws then turned it upside down and shook the crap out of it. The screws went flying everywhere and fell on the floor. Its my moms house so of course she's got gross brown carpet. How am I supposed to find my screws in that? I get the vacuum out and go over every inch of the floor to suck up all them screws. Then I dump the bag on the table and all I find is a bunch of hair and gods knows what else, but no screws. When I look for my phone I see its covered in all that stuff that came out of the vacuum. I mean, what's up with that? How can I work on my phone if its covered in dirt? Nobody said anything about that, did they? The average guy's gonna screw up his phone big time if he follows these instructions and nobody warns him about all the dirt that's gonna end up in his phone. Are you kidding me!! Now what?

Here's a little vacuum trick for anything small: put nylons/panty hose over the end of the hose and then you don't have to dig thru the bag contents.

how can i take out the screw if it is stripped

Manny Chaidez, · Reply

with a small driller, but I guess it is very difficult. Never attempted that myself on an iPhone.

lantzero,

There is no screw in Step 2?

Is the screw stripped or the head stripped?

I have used superglue on the screwdriver to remove a stripped screw, it would turn but not come out, with superglue I could turn and pull the screw out. May also work on a stripped head.

Trevor,

If you are careful, use a Dremel tool and a micro drill bit (sold where Dremel tools are purchased) to drill it out. Last resort kind of thing, good luck.

I didn't see any extra screws holding the back in place. I had to use the included pry tool to get the back off. Just start at the bottom and pry gently...if you just "pull" like the guide says it won't work.

On reassembly, be sure to clean the metal plate at the place of contact with the tiny pressure contact mentioned in step 4.

The replacement panel I got had two sheets of protective plastic on the inside and one on the outside. I used a toothpick to carefully lift and peel the two inside sheets off. One small one was over the lens on the inside. The other was over some large brown sheet of unknown function (though I think it goes over the battery). When I peel that away, some of the brown material tried to lift of with it, so be very careful.

On my phone at least, there is a small gold and black part held down under the top screw. It goes black side up with the pressure contact touching the back of the phone when the cover is in place. Keep an eye out for correct orientation as you dismantle.

James Molyneux, · Reply

I also had a small black and gold connector held down by the top screw on this step.

While the text refers to the pressure contact, the pictures do not show it clearly. The closet one that does has the yellow circle covering much of it. I was not sure if it was under or on top of the cover when re-installing. It's under.

gregsrow, · Reply

This step needs a few more caveats.

The bottom screw on my phone was locked with some thread adhesive, and required more force to loosen it than I expected.

Even after removing the screws, the battery connector was rather firmly seated, and required a fair bit of persistent gentle prying with the opening tool before it came loose.

The ground clip came loose and nearly flew off while loosening the connector, so it would really help people if there were a warning on this step to watch out for the ground clip and make sure it doesn't bounce away.

Despite putting a large amount of pressure on the screw I can't get the blades of the 00 to take. Has anyone tried with a 000 and does it work better?

abeardsa, · Reply

The 00 didn't work much for me but I had more success with a Phillips #0

DMcG,

I find the #00 doesn't work either. I use the #000 and it works better for me.

Keith,

The battery connector is attached to the battery. You're not going to completely lift it out and remove it. It pulls out from the socket you can see in step 5 picture 3. The pressure contact (little black and gold thing) will probably just slide out from under the connector. Not a problem.

DMcG, · Reply

Which screwdriver works best then. I got the #00 philips from ifixit. I agree - it strips the screw and does not work. I don't recommend it.

I am now trying to buy another screwdriver - but which one. #0 or #000. Anyone done this. Please help!

The iFixit screwdriver that is recommended and provided will strip the screws here. HOLD OFF. I bought a ph000 screwdriver off the internet. Worked fine. Don't be tempted to proceed with the ph00 from iFixit. IT WILL STRIP!!

seconded. after shipping (to spain, plus surprise import taxes) and nearly $100, the 1.7 mm screw would not budge and ended up stripped. uncool.

jejerez,

I completed this repair without removing the battery. I think the guide should be edited to note that battery removal is not necessary.

A little late to ask but how did you do this without taking the battery out? My screws are a pain to get out and if there is a better way of doing this then I'd like to try.

josephcon1998,

I completed this successfully, but this step gave me the most trouble. The pressure contact is really difficult to reseat. So much so that it should probably be called out more clearly in it's own step.

If your pressure contact pops out you might find the video at http://www.hightechdad.com/2013/05/07/ho... helpful

When reinstalling the position of pressure contact must be explained better! It took me about 5 min to understand how it fit!

Jorge, · Reply

In french: attention avant de retirer le contacteur de la batterie. La vis du haut tient "en sandwich" une petite pièce métallique noire et dorée. Cette pièce a pour but de faire contact de masse avec le dos de l'iphone quand il est refermé. Donc il ne faut pas la tordre. Quand les deux vis du contacteur sont retirée, attention au moment de débrancher le contacteur: cela va faire bouger cette pièce qui ne doit pas être abîmée ni tordue. Au remontage, il faut bien la remettre en place sous le contacteur de batterie: il est tout à fait possible de mettre d'abord le contacteur, puis de glisser la petite pièce au dessous pour qu'elle soit bien à sa place, le trou en face du trou de vis et du trou du contacteur. En remettant la vis, la pièce tient bien en place. Elle doit bien continuer à dépasser de manière a faire contact avec le dos de l'iphone.

Top screw didn’t move with iFixit Philips #000 driver. The metal is too soft and in the result the screw was damaged while still in place. Having nothing to lose I also tried #00 and #0. Any way to remove the stuck screw? I would gladly saw it off if I could.

Ok, I had to drill the screw to break it. It was very delicate and time consuming operation. But in the end the screw cap finally broke off and I was able to remove the battery!

viktorcode,

The Liberation Kit Philips head screwdriver strips the battery connector screws! It stripped the ne 1.7 mm Phillips screw circled in red in the photo above. I was able to remove the other screw, then I lifted the battery connector off while the red screw was still in position and wound the connector around in circles while lifting upwards and managed to unscrew the stripped screw. Advice, find a decent philips heard screwdriver for the internal screws like the two found on the battery connector.

When reassembling, use EST tweezers to get align the pressure contact over the top screw hole. using the pointy end of a spudger to assist: put the point through top screw-hole on the battery connector, then through the pressure contact and into the screw-hole. this will help to keep the small piece in place while re-seating the battery connector. Leave the top hole spiked as such until the screw in the bottom hole is gently fastened. Remove the spudger and replace the top screw.

Pressure contact needs to be remain EXACTLY in the same position if you remove/replace battery. I had to re-open my iPhone 4S after a battery replacement (the mobile connectivity was lost) and tweak the position of the Pressure to restore functionality.

I used my 16x magnifier loupe to be certain I had the pressure sensor aligned with the screw hole - no problem, no stripping. I consider it indispensable for tricky steps like this, and IFixit sells a similar tool for just $14.

The pressure connector is the battery connector under the silver plate. BE CAREFUL. It seems like it'd be really easy to tear that pressure connector out without meaning to. The bronze and black thing is the ground, *not* the pressure connector. If you remove it just keep track of it and re-install it.

The phillips head screwdriver provided in the ifixit repair kit does not work well this these two screws after my first attempt at unscrewing the screws became stripped. The 1.7 mm phillips screw gave me the most trouble. It took an hour to unscrew after the screwdriver from the kit stripped the screw. I used a piece of masking tape over the screw for grip to loosen it, then used finger nail clippers as pliers to unscrew. I would recommend investing in a better screwdriver for this one step. Assembly is otherwise simple and easy.

Here's a tip if you're having trouble removing the 1.7 mm screw. I had real problems removing it – the 1.5 mm screw came out easily using a Phillips #000 screwdriver but I almost stripped the 1.7 mm screw using the same screwdriver. What I did instead was use a flathead screwdriver from the iFixit pro tech toolkit I got, the one with a "–" sign and 1.0 size. That worked perfectly!

This picture needs to be greatly enlarged! The pressure plate sits directly underneath the battery connector, but cannot be seen here. It is also flat but about half the size of the battery connector, so you won't know you've ripped it up until you have! Picture two slices of bread but not the same size, stuck together.

What if you pop off that pressure contact point?? What is its function? Is it impossible to re-attach?

Ian Booth, · Reply

No idea what exactly this step means. I just pulled the battery connector without trying to move the pressure contact. Installed new battery, plugged in connector and aligned the pressure contact slightly for the screw to fit.

Got a big scare as the phone would not connect to the cell network at first boot, only WiFi. Shut it off and when it rebooted it seemed to work. WIll probably know in a day or so if everything works fine or if there are interference issues, etc.

andries, · Reply

This is normal ... removing the battery resets internal clock to start value and your provider doesn't accept that, hence no network.

Going online through wifi or manually setting date right corrects this after a reboot.

Manolis Mylonakis,

Bill McNamara,

The black ground contact needs still more "flagging." This is a simple metal strip that is attached ONLY by the 1.5mm (upper) screw. It will help if you look at it before you remove the upper screw. Notice the gold contact arm and point. That contact point must be in a plane above every other surface inside the device when you replace the battery connector, because it makes a ground contact with the metallic inner surface of the device back plate.

When I replaced it, I used the Pentalobe driver to line up battery connector and ground contact with the screw socket post. I then attached the 1.7mm (lower) screw loosely, removed the Pentalobe driver gently, and inserted the 1.5mm (upper) screw into the assembly. There is a tab on the ground contact that helps it align properly once pressure begins to applied. I completed driving the upper screw, pressing lightly with the spudger on the battery connector plate to make sure it was seated on the pressure contacts. Finally, I completed driving the lower screw.

Matt McCaffrey, · Reply

This is a hard step because the directions and pictures are not very clear. This might help:

1) Here you HAVE TO disconnect the battery connecter (the language is confusing).

2) This is easier than it looks, as you can simply lift the connector upwards from any angle (I rested my plastic tool on the antenna and gently lifted it up).

The photo suggests you have to pull the connector backwards (which would be hard), this is not true, it can be lifted up towards you (the pins go out backwards and upwards, you'll see).

Finally, don't confuse the "pressure contact" with the "pressure contact point". You remove the contact, the contact point (underneath) sits on the board. No need to worry about this.

Wish the instructions had the warnings about the pressure contact before getting started. I removed it from the logic board because the warning was after the instructions. I managed to get it back in place and reassemble the phone. Nothing happened when I turned it on. Here I wrongly assumed the battery came pre-charged but it wasn't. I decided to plug it in to recharge it and was elated to see the empty battery symbol. I'm sending this from the phone!

I didn't find any need to remove the pressure contact. I just pried the battery connector up (gently) with a spudger and left the pressure contact in place. Connected the new battery and aligned the pressure contact screw hole. Replaced the screws, finished reassembly and all was good.

Roger Mercer, · Reply

After reassembly, the CELL CONNECTION WASN'T WORKING. You might need to slightly bend the contact in step 5 up just a little, so it will make contact with the metal back plate. Did that and it worked perfectly.

Just went through the replacement and the battery "plug" (step 5) on my replacement battery was slightly misaligned relative to the metal plate used to screw it onto the board. The plastic and "gold" "plug" was slightly askew on the metal plate, which meant that when the plug was inserted, the screw holes (step 4) were poorly aligned.

I managed to pull everything back into line using the screws, but the QC on these replacement batteries is a bit suspect.

This can be very tricky because sometimes theres just too many glue on the back of the battery, and eventually the battery will be deformed.

Carlos Lopes, · Reply

Yes, there did seem to be a lot of glue holding my battery in. At first I was afraid of breaking it, but after reading up on the subject I've learned that it is okay if the battery gets a little deformed. Due to the nature of the battery it will still work if slightly deformed.

djlogic26, · Reply

I found the plastic pull tab to be useless. Peeled pretty much the whole battery out from the left side. Used a probe to "break" a few strands of glue to help. Just watch the connector and ribbon cable in the lower left corner as you pry up so you don't crimp them or damage them.

DO NOT remove the battery unless absolutely necessary. If the battery is removed from the phone, DO NOT reuse it, ifixit does not seem to understand the importance of safely handling the battery

Tom Chai, · Reply

Tom you have never been so wrong. Removing the battery is the FIRST step ANYONE should do before repairing or attempting repairs on their phone. The iPhone has many different grounding points in the phone and having electrical current running to it poses a massive risk, especially with ESD (ElectroStatic Discharge). People, PLEASE make sure you remove your phone's battery FIRST before doing any repairs. Use a plastic, not metal, spudger, after unhooking the battery from the logic board, place the spudger along the right side of the battery NOT under the volume buttons, about an inch and a half lower (two roughly if a sim card is present) and start prying it up using the frame as the fulcrum, as you start to lift the battery from the adhesive make sure you slide the spudger farther under to get even contact so you do not damage the battery.

Prestige Computer Solutions,

Try a used plastic credit/gift card to apply gentle pressure to lift the battery out of the phone, the short edge of the card fits within the gap on the logic board side between the battery and video cables. You can also use it on the opposite side if there is room between the battery and iPhone frame. This has worked on all of the 4 and 4s models I've replaced screens on.

I offer an alternative image if interested.

Hello! My clients iphone 4s:n battery connector broke, when i tried accidentally take the battery out with a plastic tool from the wrong side.

Connector detached completely, so that the two middle ironcensors came with it and was stuck to the connector. When i screw the whole connector back to phone, it works with battery power, but the batterys downloading doesnt work. Are these two middle censors that are stuck in the connector exactly the ones that should be charging the battery? Do you know how i can fix this? I have already bought electrical conductor glue, but should the parts be cleaned somehow first? And how can i fix it, when the center metal sensors on the system board is also attached to the battery?

How can i clean out thiskind of part with windex? I have purchased almost all of the possible tools from iFixit and the electrical conductor glue i bought somewhere else. (http://www.ebay.com/itm/300915727408?ssP...)

Please, Please, PLEASE avoid using probing elements to try remove batteries. I have had dozens handed in to me with punctures and two that actually started smoking due to people trying to prise the battery out. DO NOT DO IT.

The best way I have found to remove the battery is this process;

1) Try remove it with the pull tab directly, some will come out, some will not. Do NOT use excessive pull force else it'll deform the battery and reduce the capacity.

2) If the pull test didn't work, then get a hot air gun on medium and warm up the area around the battery for about 30 seconds, focusing on the perimeter of the battery. If you see ANY popcorn'ing then you're too hot, you don't want to cook the battery.

2.1) Wait about 30 seconds for the heat to now wick underneath the battery to soften the adhesive.

2.2) Now try pull the battery up, the extra heat should have softened the glue that you can remove the battery without excessive force and without sticking objects under the battery.

Was having a hard time getting the screws back into the battery connector.

Ok, I did all the steps and phone seems to be OK, wifi is actually working again, yaaay.

But cellular connection is messed up. It will have full reception (5 pins) for about 10 seconds, then drop to 1 pin for a couple seconds, then go into "searching" mode. After a few seconds in "searching" mode it will go back to full reception and the process repeats itself in a timely fashion, over and over again. Obviously I messed up somewhere but where? Which connections are faulty/beyond repair?

I dismantled the phone again and concluded that the digitizer cable was kind of loose (don't know if that affected anything, but i put it down firmly this time). I had 2 problems, the cellular connection I mentioned plus the phone would charge to 3 percent, die, and then repeat the procedure. What I did was I took out the battery, the tin plate above the cables, and lifted the dock connector. So I did not redo that much. I cleaned all contact surfaces as I had been told but chose to not do before.... I also took out the grounding clip by the battery connectors and bent it upwards quite a bit while also peeling away 2 mm of the black insulation material on the back of the phone to make sure the grounding clip connects well to the back of the phone. I also cleaned that surface with window cleaner, which is basically isoprypol alcohol as has been recommended. The cellular antenna connector I pushed down firmly to make sure it was connected, I was gentler the first time, now everything works.

On reassembly, note that the metal lip below the (red) 2.7mm screw and to the right of the (green) 1.2mm screw goes between the ribbon cable and the main logic board, as can be seen in the picture for Step 12. If you don't get this right, the 2.7mm screw is difficult and, worse, there's a risk the edge of the lip will tear the ribbon cable.

Got to step 13 and could not remove the 1.3mm screw (yellow circle), even using a different Phillips head screwdriver than the one that came with the kit. So frustrating. Was able to remove the other screws leading up to this point without difficulty (used the saran wrap trick on the other screws to prevent stripping, but this 1.3mm screw just would not budge).

Ended up abandoning the screen replacement--luckily the phone works after putting it back together.

If you just very slightly twist this plate clockwise as you are lifting it out, it will help as there is a little hooked piece at the lower edge on the very far right. You have to be careful not to turn it too much though because this hooked piece is right beside a ribbon that could be damaged.

Trisch, · Reply

To add to Trisch's comment:

If turn the plate clockwise doesn't do the trick, the hooked piece on the lower right comes off when you pull the plate towards you a tiny bit. Still, watch out not breaking that ribbon the hooked piece is behind of.

I recommend that steps 20 and 21 are swapped. It's much easier to remove the wifi antenna flex from the board using the blue spudger if the board/PCB is still secured with the 4.8mm screw.

Removing the screw first makes the PCB move up too much when you're trying to detach the wifi flex and can lead to mishaps.

Ok so no fret here if you accidentally pull off the metal insert placed on top of the actual antenna. This step needs to be rewritten imo, the deal here is that there is an actual 'socket' looking deal underneath here that you need to lift up. There is a metal tab semi'glued' to that part of the antenna and it does come off easily, however all you need to do is press them back together to get them back, I believe it to be a range 'extender' of sorts.

So your looking to actually lift up what looks a lot like a ribbon cable as well in this step. YOU SHOULD NOT HAVE A PIECE REMOVED IN THIS STEP, it's still in the case at this point.

hey, i removed the logic board and gave it a bit isopropanol spray. is this ok? how can i found out if it is working? is it possible to remove something from the logic board? thank you :)

On reassembly, make sure you lift up the power button cable before installing circuit board. I thought I had all of the cables lifted until after getting to step 17 (in reverse) only to find out power cable was under the circuit board. Added 15 minutes to my process.

juanocasio, · Reply

I had a similar problem as I was back tracking steps to perform something I missed and actually broken the power and sensor cable (the one that is connected to the digital board first during re-installation. A secondary order and another 20 minutes took care of it. Glad you were able to not hit that barrier.

Hi. This little clip is responsible for the image stabilization on the 4S. When the iPhone 4S was launched, one of the things that were different from iPhone 4 was Image Stabilization, specially when the user was filming. This clip holds the camera module in place while the phone is shaking in the hands of the user. Pretty high tech :D

Pedro de Almeida Silva Chaves,

Apparently it had uncovered my iPhone before, because when I did not find this piece uncapped here. I need to know which function is on the iPhone and if it is very important. How could I get?

Hi, I had the phone apart to replace the wifi chip.

Has anyone found a source for the two nano sized SMD resistors, because this also causes "no wifi" syndrome due to them being important for the I2C lines.

thanks!!! -A email testing_h "at " yahoo.com

I think this is one of the parts I didn't put back in... Does it affect anything?

Also, Took apart my iPhone 4S to fix the screen and battery... Now the camera light doesn't turn on and I'm left with two pieces. Help!

Here are the parts: http://imgur.com/DsYtdlR

Left part: See step 5 - "Take notice of the small black ground clip on the upper screw of the battery connector".

Right part: See step 25 - "Be sure not to lose the small grounding finger for the rear facing camera near the power button".

Simon Fransson,

I removed this in step 22 even though it only slightly alluded to it. If you did, too, don't panic. Go find your step 22 parts and verify it is there. :)

This is really hard to get out. I broke 2 plastic spudgers (cheap/free) trying this

david, · Reply

it might be an idea to mention that the retainer has three tiny little clips that point outwards from the camera and while taking it off is hard, putting it back on is even harder

david, · Reply

Step 26 cause me great pain as well. I couldn't get it loose with the plastic spudgers. I had to break out a tiny metal screwdriver. I was so paranoid that I was going to break the part or the clip. The trick is to get under the clip's "fingers" that fasten it on the sides. The issue is that even my small my plastic spudger was too big to fit in the available space. Ultimately I got it to work with a micro flathead screwdriver, but it wasn't without serious concern.

Song, · Reply

Using a micro flathead screwdriver did the trick. I found that prying from the top right corner worked best.

Dan, · Reply

Yes, this is hard. It would be a lot easier if the guide had a picture of the retainer clip. I was successful with a spludger by lifting it on the upper left hand corner. Once you have it off, have a good look at it before putting it back on. Remember that it clips to the outside of the camera housing.

The clip has a hole and a groove. This is good enough to grab it with some pin tweezers from the top when replacing it.

DO NOT DO THIS,

it is unnecessary to remove this plate or the front camera. its very difficult to remove and very difficult to replace. totally unnecessary step. just be careful moving the flex cables around, that's the only thing that is in the way, the camera does not hinder the power/sensor cable.

Andrew, · Reply

fyi my comment is based off replacing the power cable not the front camera, apparently the guides are just copied off one another. again, this is one of the hardest things ive done on an iPhone. if you are fixing the power cable, DO NOT pull out the front camera, NOT NEEDED and VERY HARD. im currently still trying to re-install the cover plate.

Andrew,

I totally agree with Andrew, when changing the power and sensor cable, do not do this step. It is absolutely unnecessary and only increases the pain when reassembling your phone. That step should not be in the guide for the power cable replacement.

corgold, · Reply

I agree with Andrew, this step is not needed.

If you are replacing the headphone jack, DO NOT DO THIS STEP! It's totally unnecessary.

nikbrauer, · Reply

Based on comments here, I skipped this step fixing the power button and it was fine, you have a little less room to remove the earpiece wrapped in the power cable but if the removal was as hard as people describe, it was easily worth it.

davisyang, · Reply

I could not reassemble the retainer. The legs would not go back to where they were meant to go and I badly bent one in the process. I replaced the retainer with a small dop of Blu-Tack ("a reusable putty-like pressure-sensitive adhesive"). This gets squashed down when you replace the logic board. This keeps the camera correctly positioned and works OK so far.

gregm, · Reply

If youare changed the earpiece you can skip step 26 till 31. got to step 32 and remove the black clip without disassembly the earpiece assembly and then tear of the speaker. follow the steps of the crazyphones on youtube guide.

mikenuke, · Reply

I think the key to getting this clip on is knowing that the fingers do not clip on the inside of the retainer, but slide over the top and the 'elbow' locks in the retainer openings. This makes it a ton easier.

true, don't remove it

anakinskyfighter, · Reply

This is the most dangerous step of all !!! You have to be VERY careful with the digitizer and screen ribbon cables when you bend it back to unscrew lock button. It is best to partially remove the screen so that you can get the cables out of the way (you've already disassembled most of the phone anyway, a little more won't hurt). The first time that I did this repair, I ended up damaging the cable and my screen was useless. Many people that I have talked to suggest the same thing!

Felipe Da Cruz, · Reply

This exact thing happened to me. Be very careful as a cheaper power/sensor cable repair can quickly turn into a more expensive screen replacement as well.

umagon1337,

My screen is stuffed too. All because I bent the cables like the photo.

Stephen Shaw,

Yea, this went wrong in my attempted repair last night. It would be really great if step 28 included a warning here, or insert a step to remove the screen so those ribbon cables are safely out of the way!

I can't tell you how disappointing it is to find the cause of my failed repair in hidden comments 8^(

bdv, · Reply

Another solution for this step is to carefully push the digitizer and screen ribbon cables down (into the back of the front screen) instead of bending them back. If you do this carefully, you can minimize how much the cables bend and still have enough clearance to angle a screwdriver in from the top to remove the rightmost screw.

This worked for me without damaging the cables. I did not have to remove the front screen either.

Michael Huynh, · Reply

I tried this and it worked, thanks. I was worried with the comments about damaged video connectors, but everything luckily worked after putting it back together and powering on.

davisyang,

Also, if your "power button is stuck", you may not have to replace the whole power cable. After you unscrew the power button bracket, you should see a small black dot in the center of the gold colored area (where the button makes contact). Usually, stuck power buttons mean that either this black dot has worn away or has been shifted/misaligned. If the black dot is misaligned, put it back in the center and test if this has solved the issue. If the black dot does not exist, find/cut a small piece of rubber and carefully glue it to the center of the gold area. I cut a small piece of rubber from a thin o-ring and then used a dab of superglue to attach the rubber. Another commenter used nailpolish instead of rubber to create enough height to contact the power button. After all of this, screw the power bracket back on and test the power button. If the power button does not click, it may be that you screwed the bracket on too tightly such that the button is always depressed. Loosen the bracket screws.

Michael Huynh, · Reply

I guess this is where I lost the screen. In any event... the power button now works, and I have sound, but no picture. I can't even punch in my PIN to reformat the phone and give it away.

Btw, this was written in the comments for the 4S Power Button and Sensor Replacement, so if you see it anywhere else, caveat lector

steve,

I was careful but I did kill half the digitizer, presume a broken cable and will sell it for parts.

paulverket, · Reply

The right hand screw thread stripped on my repair. I reassembled it with only the left hand screw holding it in and it is working OK.

gregm, · Reply

Maybe it's just me, but I had a hard time getting the earpiece out as it was wrapped in the ribbon cable and also had adhesive on it. Folks should be super careful here. Ultimately I torn the cable, but since I was replacing it anyway, it was ok. It really had me worried for a bit.

Song, · Reply

how are you supposed to stick the new wiring to the bits ?

This isnt worth doing.. Run the risk of your light sensor not working, and the lock button still not working.

i haven't done it yet but im looking at a replacement part and mine has double sided tape already affixed to the flex cable to secure it.

Im doing this job for a friend as trade for free haircuts lol

Waste of time.. I did this to fix my lock button. all it did was make my light sensor not work. lock button still doesnt work.

"Do not completely remove the earpiece speaker as it is still attached to the power and sensor cable assembly."

I just have one question: why?

It appears from the photos that there is enough play on the sensor/power cables to remove the earpiece speaker in this step if you're careful; avoiding steps 31 and 32 and jumping to 33. Any help would be great as I am about to attempt an earpiece speaker replacement tomorrow.

ladjr, · Reply

I've torn the corner of the power ribben, the bottom right hand corner of the loop below the speaker. Will the ribben still work or do I need a new power ribben?

Doodling101, · Reply

I had a terrible time with this step, which doesn't mention that the tiny black clip holds the sensor in place. I finally got the clip off, and the sensor out, but the tiny black clip was deformed and I had a horrible time getting it back into place. All of the various ribbon cables are really working against you, too. The black clip is so tiny that it's very hard to align properly on the sensor (it wants to flip onto it's back and "turtle") and often pressing on it to snap it back into place simply bends it rather than locking it on.

I had accidentally broken the ribbon cable near the logic board connector for this whole assembly; now that the phone is back together, everything works EXCEPT the light sensor that I had to manipulate so extensively. I'm assuming I damaged either that portion of the cable, or the sensor itself, struggling to get it back into place with the clip.

Jason, · Reply

IMPORTANT. As Jason mentions, there is a small black metal clip which you MUST remove first. It's actually got hooked ends so if you grab it from the middle and pull it will simply deform. Instead grab a small flat head screwdriver and place the flat of the blade under the metal clip - come in from the top at the point where the tiny hole is, then move the tool to the left (toward the speaker jack). It should ping the hook out (be careful it doesn't launch across the room!) and the piece will then just drop out.

thierry28722, · Reply

eventually , I got it right , after at least one hour , with the help of Jason : Tip : when removing this clip , take a photo of it for re assembly .Before re assembly : re bend this clip right as it may have change chape . Place the sensors , put the clip above and put the right side on position below the two sensors then , push gently on the left by bending away with a small screwdriver, release and it may be locked.

This clip goes above the earpiece assembly .To get away with all the cables , glue them away temporarily with scotch on the battery compartment.

Go ahead and order a new speaker - its nearly impossible not to break the foam

nweeks, · Reply

The foam can be replaced by similar double side tape.

davidsotl,

Tools plus parts plus shipping (FedEx) costs me about $100. Probably would cost about the same to have some do it for me, but what's the fun in that! The small magnetic mat is a must have, so handy.

davidsotl, · Reply

Agree with "nweeks" on it being impossible not to break the foam. However, I reinstalled without the foam. Since the earpiece is wrapped in the ribbon cable and it's also very securely contained in the recess, I can't see the foam adding a ton of value. My phone worked fine after I reused the earpiece without any new foam.

Song, · Reply

Its really easy to remove the foam and tape intact and re-use. grab an exacto blade and slice in between the flex cable and foam, once you have the edge started it will sparate pretty easily. dont worry about damaging the cable, you're replacing that anyway.

Andrew, · Reply

I tried this and it worked easily. Thanks for the tip.

davisyang,

Does it matter which orientation the earpiece gets reattached to the cable?

Robert Lindsley, · Reply

The second piece of tape was missing on the new speaker I purchased. The speaker buzzes for voice except for loud/slow speaking.

wmarkwitherspoon, · Reply

On reassembly, fix the earphone speaker before the top sensor assembly. The first step is to glue the Power and Sensor Cable down on the iPhone base. Then put the earphone speaker on top of the cable, oriented as in the photos. Then bend the cable over the speaker and reassemble the top sensor assembly.

gregm, · Reply

Note: be sure that the foam on your brand-new replacement sticker is centered properly! Mine was originally glued down onto the speaker improperly - off-center. This made the foam touch the actual speaker diaphragm instead of just sitting on the case, and made it extremely quiet - almost inaudible. It took two tear-downs for me to think of trying to re-seat the foam, but it immediately fixed the problem.

I figured it out, the new tabs have SMALL new strips of tape on them. Just have to scrape it a little to see them...
