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.

Image #1

Edit Step 2  ¶ 

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

  • The panel will move about 2 mm.

Image #1

Edit Step 3  ¶ 

  • Pull the rear panel away from the back of the iPhone, being careful not to damage the plastic clips attached to the rear panel.

  • Remove the rear panel from the iPhone.

Image #1

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 device.

  • 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.

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 VERY careful not to remove the pressure contact point from the logic board. There are 4 very small soldering points awaiting this mistake!

Image #1

Edit Step 6  ¶ 

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

  • Run the plastic opening tool along the right edge of the battery and pry up at several points to completely separate it from the adhesive securing it to the outer case.

Image #1

Edit Step 7  ¶ 

  • Use the exposed clear plastic pull tab to peel the battery off the adhesive securing it to the iPhone.

  • Remove the battery.

Image #1

Edit Step 8 Dock Connector Cable  ¶ 

  • Remove the following screws securing the dock connector cable cover to the logic board:

    • One 1.5 mm Phillips screw

    • One 1.2 mm Phillips screw

  • Remove the metal dock connector cable cover.

Image #1

Edit Step 9  ¶ 

  • Use the edge of a plastic opening tool to pry the dock cable up from its socket on the logic board.

Image #1

Edit Step 10  ¶ 

  • Peel the dock connector cable off the adhesive securing it to the logic board and the side of the speaker enclosure.

Image #1

Edit Step 11  ¶ 

  • Use the edge of a plastic opening tool to pry the cellular antenna cable up from its socket on the logic board.

  • De-route the cellular antenna cable out from under the metal fingers attached to the logic board.

Image #1

Edit Step 12 Rear Camera  ¶ 

  • Be wary of the outer plastic ring located on top of the rear camera's flash assembly. It can be easily displaced if not removed during disassembly.

  • You can use tweezers, a plastic opening tool, or a spudger to remove the outer plastic ring.

Image #1

Edit Step 13  ¶ 

  • Remove the following four screws securing the cable cover to the logic board:

    • One 2.7 mm Phillips screw

    • One 2.6 mm Phillips screw

    • One 1.3 mm Phillips screw

    • One 1.2 mm Phillips screw

Image #1

Edit Step 14  ¶ 

  • Use the edge of a plastic opening tool to pry the cable cover tabs out of their slots cut into the EMI shield on the logic board.

  • Lift the cable cover from its edge nearest the top and remove it from the iPhone.

Image #1

Edit Step 15  ¶ 

  • 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.

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.

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.

Image #1

Edit Step 18  ¶ 

  • Remove the 1.5 mm Phillips screw securing the grounding clip to the logic board near the headphone jack.

Image #1

Edit Step 19  ¶ 

  • Use the tip of a spudger to pry the small grounding clip up off the logic board.

  • Carefully grasp the grounding clip and remove it from the iPhone.

  • Before reassembly, be sure to clean all metal-to-metal contact points on the grounding clip (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.

Image #1

Edit Step 20  ¶ 

  • Use a small flathead screwdriver to remove the 4.8 mm standoff near the headphone jack.

Image #1

Edit Step 21  ¶ 

  • Use the edge of a plastic opening tool to disconnect the Wi-Fi antenna from the logic board.

Image #1

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.

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 standoff.

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.

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 26 Vibrator  ¶ 

  • Wedge the plastic opening tool between the vibrator and the side of the iPhone.

  • Pry the vibrator up to release it from the adhesive securing it to the iPhone.

  • Remove the vibrator.

Image #1

Edit Step 27 Speaker Enclosure Assembly  ¶ 

  • Remove the two 2.4 mm Phillips screws from the sides of the speaker enclosure assembly.

Image #1

Edit Step 28  ¶ 

  • Remove the small plastic bracket that was installed under the screw closest to the dock connector cable.

Image #1

Edit Step 29  ¶ 

  • Remove the speaker enclosure assembly from the iPhone.

  • Before reinstalling the speaker enclosure assembly's screws, be sure the Wi-Fi grounding fingers are installed below the lip in the iPhone's metal case as seen in the second picture.

  • Before reassembly, be sure to clean all metal-to-metal contact points between the grounding fingers of the Wi-Fi antenna and the case of the iPhone with a de-greaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to cause wireless interference issues.

Image #1

Edit Step 30 Display Assembly  ¶ 

  • Remove the small pieces of black tape covering the display mounting tabs.

  • Note: These corner screws are not the same thickness as the other 1.5mm screws. Set them aside separately.

Image #1

Edit Step 31  ¶ 

  • Remove the 1.5 mm Phillips screw securing the display assembly near the power button.

Image #1

Edit Step 32  ¶ 

  • Remove the 1.5 mm Phillips screw near the headphone jack.

Image #1

Edit Step 33  ¶ 

  • Remove the 1.5 mm Phillips screw near the lower microphone.

Image #1

Edit Step 34  ¶ 

  • Remove the 1.5 mm Phillips screw near the dock connector cable.

Image #1

Edit Step 35  ¶ 

  • Loosen the three large-headed Phillips screws along the volume button side of the iPhone about one half turn.

  • It is not necessary to completely remove these screws. When reinstalling the display assembly, be sure the washers are closest to the screw head (as seen in the second picture).

Image #1

Edit Step 36  ¶ 

  • Loosen the three large-headed Phillips screws along the other side of the iPhone about one half turn.

Image #1

Edit Step 37  ¶ 

  • Use the edge of a plastic opening tool to gently pry up the display assembly around its perimeter.

  • Remove the display assembly from the iPhone.

  • When reinstalling the display assembly, make sure the digitizer and display data cable are completely pulled through the slot cut into the outer case. Otherwise, the digitizer cable will not reach to its socket on the logic board.

  • Remember to switch the home button from your old display to the new display (in most cases, this is not provided). The home button is thin rubber, so care must be taken not to tear it, or it won't work when transferred. Also check that the mesh for the speaker hole is present in the replacement; if not, move it over from the old display.

  • After reassembly, protect your new display from any scratches by installing a new screen protector.

  • Follow the guide in reverse for reassembly.

To reassemble your device, follow these instructions in reverse order.

Excellent guide, thank you.

One thing to note, on Step 23 i'm not so sure the screw is a 1.6mm, pretty sure it's larger than that.

Great stuff, thank again!!

Helpfull tip... I printed these instructions and then taped each screw to the spot in the instructions with scotch tape.

AWESOME guide - very impressed. All works but I did wind up with an extra part so I must've improved upon Apple's design. The part is a small, rectangular grounding clip (black and gold) with a single brass finger and a hole through the black part... this is NOT the one mentioned in Step 26. Not sure from where it came off & not inclined to dig back into it - but would love to know where it was from. It's 1:30 am here and I may be overlooking something idiotic... any help would be much appreciated. Thanks again, Jim

Jim McAward, · Reply

Turns out my "extra" part was the one that James Molyneux mentioned, which comes out as part of Step 5. (The clip provides a bit of extra ground contact between the back of the WiFi antenna and the rear case.) Again, totally awesome instructions - thanks!

Jim McAward,

I used rubber gloves to completely disregard the whole washing with windex

After the entire grueling process, I was confident in my repair. Everything works... Except the touch screen. I disassembled and re-assembled at least 3 times but to no avail. Everything seems to be working fine, no tears, bends or breaks in the cables... Anyone having a similar issue? So bummed...

The cable of the digitizer was likely damaged. Happened to me because of my carelessness. Had to change the screen again.

jppellet,

EXCELLENT guide. Part recommended, LCD (digital assembly) was the exact fix I needed. Step by step with recommendation & tools were perfect. One of the blue plastic tools did break but my son was able to work without it after. It took him 1hour & 50 mins. I read everybody's ideas and helpful hints & all were very much appreciated. Thanks Again :)

I noticed that I lost all of my pictures and videos while completing this procedure. My text messages and other data remained, but my pics and videos were wiped out.

The black tape in step 22 seems to be important to put pack. I did have problem with a touchscreen that did not work from time to time. The black tape was forgotten and when putting it back the Iphone worked fine.

Peter H, · Reply

happy with replacement, great guide. two things happened; while reassembling I realised late that I had caught the power button connector cable under the logic board; I had to go back and lift logic board to find and reconnect, but now power button does not work at all. Bummer, but you can get at most of functions with the assistive services module. Second issue is I have noticed what I think might be a change in calibration of the GPS; I use RunKeeper and suddenly my routine morning run seems to have stretched in length and increased in pace! not sure what to do here--any advice?

paulgilna, · Reply

I stupidly removed the battery connection whilst the phone was on with a small flat metal screw driver, which in turn has blown something up in the phone. has anyone else done this before an know what part it is i now need to replace?

Vinnie Ebbrell, · Reply

Great Guide.

Did the change in a bit more than 2 hours with some little breaks in it... so I would say working time about 2h.

First at turning on I was shocked, because the iPhone couldn't find any network (carrier), but a few reboots later and after setting time and date it was fine. (Read somewhere that setting the time could make a difference in detecting carriers)

You wrote the details the way I should have. but there is no point in just repeating all you said, Thanks ;-)

Pierre Merineau,

I'm thinking of following this guide to fix my missus iPhone 4S as if I bought the parts it's a lot, lot cheaper than paying someone else to fix it. Is it wise for me to have a go at repairing her phone? (She dropped it and smashed the glass but the phone is still usable)

I made a crude MS paint outline with circles and shapes where all the screws and parts go, print the drawing, and set all the parts where they go...makes it very simple

Outstanding guide. Worked. Key is to stay organized!

alex sass, · Reply

Awesome guide. I was lucky to have a friend tell me to Google "iPhone screw chart" before I performed these steps. I printed out the screw chart & set all the tiny screws/parts on it. Really helped for re-assembly.

Also wanted to mention that I bought my screen from Group Vertical on Amazon, shipped from USA + PRIME eligible. It arrived in 2 days, very high quality.

Good luck - remember take your time, never force anything. Some of the adhesive is strong especially on the battery and vibrator. Don't forget to transfer your speaker shield and home button. Do these with extreme caution or they will rip.

Thank you so much for this guide! Some fellow student brought their iPhone with a screen replacement up to the "Nerdery" in our school (I have no idea whose it was). The procedure went well, I would have been lost without this guide. The documentation is great! Telling us the screw sizes really helped because I was able to organize them and label them with the magnetic project mat.

One slight error on my part however. After I completely reassembled the phone and was turning it on, I noticed that the screen replacement didn't have the mesh covering for the earpiece! Tomorrow I am going to redo the whole thing just so I can take the mesh covering from the old screen and install it on the new one.

Pro tip: Pay very close attention to all of the little details! Get the magnetic project mat with marker, it helps so much. If you don't have it, you will confuse screws and lose parts.

Thanks again for the great guide!

Excellent Guide! it was a bit time consuming but i took the slow and cautious route and with the iFixit pro toolkit had all the tools i needed for the job plus with the magnetic project map all the many parts and screws stayed organized! (no i wasn't paid to say that lol) but the disassembly wasn't as big of a nightmare as i thought it would be. Keep up the great work!

Absolutely the best procedure I've ever followed. The only thing I'd suggest is making it possible to display the large photograph for other than the first photograph in each step. (Of course, it's possible that this is already possible and that I simply am not smart enough to figure it out). Anyway, managed to repair my daughter's phone in a little over 2 hours - I'm wrapped!

Thank you very much!!! Excellent guide, I would have never been able to do it without this guide!

Be VERY careful when you put the new replacement screen (STEP 37).

I cut the data cable of the digitizer and had to wait another 2 weeks before getting a new replacement screen! The digitizer cable must not be bent at all otherwise it will not reach to its socket on the logic board!

All the other steps were almost easy to do!

Incredible bad quality spare part (iPhone 4s screen). incredicle bad quality tools, I'm non asking for Wiha tools, but these are really terrible. First chance: flat cable from digitizer broken (I use to manage with thiskind of cables). Buy a 2nd screen (big mistake!). The screen is terrible and you can see the six leds in the top, like you have six bulbs over your screen. Problems with signal. Disassembled again and applied isopropanol to contacts. Fantastic, the bad screen quality traped some drops between screen layers. Had to dissasemble the screen to try to dry the drops (which ofc appeared on the image). Assembled the phone again. Power button did not work at all, and display image was as poor as before cleaning the layers. Very low brightness in front view and normal from a 170 degrees angle... Well, opoened the phone again, with others tool ofc, since the ones provided by ifixit were unusable, pull out the main board to protect my data and throw the rest to bin. Buy some screen cheaper from eBay.

The Liberation Kit just stripped the screw. Now what.

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!

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.

Jack, · Reply

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.

Kevin Keenan, · Reply

I was missing the lower screw in this step. Reinstalling the other screw was difficult. Screw either stripped or (I think) screwdriver 00 is not right for removing this/ifixit screwdriver sucks.

maxrobins, · Reply

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.

threephi, · Reply

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,

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!!

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

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.

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

If I did accidentally remove the pressure contact point from the logic board...what do I do?

Samuel Z, · Reply

I also did this. Not sure what its for? My phone appears to be fine now without it.

Ian Booth,

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.

S Byers, · Reply

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

I also accidentally removed the pressure contact. I put it back in place as best I could during reassembly and so far haven't ran into any problems.

The black & copper contact piece is missing from my iPhone. Does that explain why my phone won't restore and keeps re-booting? I have tried every kind of restore with no luck. Any ideas?

After reassembling the iPhone I the GSM connection wasn't working. After cleaning all parts with isopropyl alcohol it still didn't work. What solved my problem was to turn on WiFi and then synchronizing the date and time which was set to 1970-01-01. After a reboot everything worked just fine. :)

Florian, · Reply

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.

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.

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...)

Removing the battery wasn't necessary. I attempted the removal but decided not to in the end. It didn't get in the way at all.

BigFatCat, · Reply

i also skipped the battery removal step. the battery didn't get in the way, but it did make it difficult to see if the wifi grounding fingers (step 14) were underneath the case lip. everything worked in the end though so i don't think removing the battery is a strict requirement.

rippergirl, · Reply

How can you not remove the battery in a battery replacement fix? Step 14, there are only 7 steps. Me thinks these comments are getting mixed up between different fixes!

bluezzer,

I did not remove the battery to do a Speaker replacement and had no issues with getting the Speaker out/in. So, steps 4 and 5 are required but not step 6.

rcrodriguez2, · Reply

The plastic tab is not attached to the battery. I just pried from the right and slid tools under until I broke all the adhesive.

I found it easier to start by pulling the plastic lip to loosen the battery, then, if needed, use the plastic tool to pry from the side.

Be VERY careful NOT to pull off the part of the connector that is on the logic board! Mine now has only contact but no solder until I can get a small enough soldering iron and a less shaky pair of hands!

I lost the 1.5mm and 1.7mm screws when replacing my 4s battery. Is there a place that sells just these two screws? I bought a 4s screw kit from Zeeton.com but figuring out which screw out the of 39 screws were the the 1.5mm and 1.7mm was impossible.

Buy a cheap pair of digital callipers ($20 -$30) and it will be clear. You can then use them to measure all kinds of things instead of squinting with a ruler.

bluezzer,

I bent the wire of the silent button on right top of the battery. Now the silent botton don't work. The wire on the bent is half-cut. BE CAREFUL when you put the new battery inside!

Was having a hard time getting the screws back into the battery connector. Read another tip online that helped - pushed the end of my phillips screwdriver into some soft candle wax which gave it just enough stickyness to have the screw stay attached to the screwdriver while I was moving it toward the hole. Thought I'd pass that along.

bill, · Reply

I did as wazzamagu did (and stated above), "My Pentalobe tool was slightly magnetized so I used that to bring the screws in for tightening with the Philips screwdriver." That made replacing the screws fairly easy. Thanks for all the advice on this page. It was not hard at all. Go slow and carefully, everything is smaller in there than I expected. The "searching" thing came up as it seems for most people, but just took a reboot and all is fine.

Fabulous tutorial! Many thanks! i have now a working iPhone back after display crash and glass brake!

In Step 8 I think the colors of the screws are inverted. The larger screw is at the left (near the sideboard) and the smaller is in the middle, near the battery (iPhone 4S).

I was not able to really screw any of these screws back in successfully using Ifixit's screwdriver. I did the best that I could and reattached and replacement camera is functional AOK.

Not sure if it is because has been repaired before -- front screen replacement -- or if screws just fragile and screwdriver sucks.

Plan to see if can get replacement screws for inside the device.

maxrobins, · Reply

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.

David Bruce, · Reply

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.

Is there a reason for waiting until step 18 to remove the sim card and its holder? I can do it right before I start without much force, is this not better?

jmaelzer, · Reply

I agree that the SIM card should be removed before you even start. After I completed this repair (waiting until this step to remove the SIM), the SIM card and holders won't go flush with the side of the phone anymore. The phone still works and everything else is fine, it's just annoying that I have a SIM holder sticking out about 1mm. I'm not certain this step caused this, but I'm just letting folks know that I agree with jmaelzer.

There is an additional cable that you have to disconnect that's under the headphone jack cable. You have to do this before you try to remove the logic board. Otherwise, you'll rip that cable.. and I just freaking did.

Note that there is a rubber insulator that is loosely attached to the PBC that can be seen in the upper right corner of the red outline near the tag with Q5M on it. It falls off after the logic board is removed and should be replaced before reassembly.

So, I couldn't gind the tape and instead of digging around. I did what no one should do. I twisted and pulled. So now the screw that holds the upper left corner on broke that part of the logic board off. Everything else went back great....Phone won't turn on. Am I screwed here?

cdays01, · Reply

After I had lifted the logic board and moved around a little a small rubber piece fell off. Approx. 1 cm long and 2 mm wide. I'm guessing it's for some sort of isolation between the board and the chassis. Where should it go when I reassemble the phone?

The piece I'm referring to can be seen on the table in the upper right corner in this video: http://www.youtube.com/watch?v=IVQtgD89e...

It sits between the logic board top-edge and the two ribbon leads from the screen. Its purpose is to stop the PCB cutting in to the FPC leads over time due to vibrations. If you require I can send a photo.

Simon Fransson,

Be very careful when removing this screw, as the angle of your screwdriver may risk stripping it. In order to be 100% safe, it may be worthwhile to remove the headphone jack connector. (There is a guide to do this as well.)

Kris, · Reply

I've never taken this phone apart before and this screw is missing entirely.

sarawr,

This screw, as well as being difficult to get to in order to remove it, is very difficult to replace. Much patience is required as you can't get the right angle on the screwdriver to start with.

I suspect, given there are 10 screws holding the screen in !!!, that this one could be left out during a rebuild... especially as 'sarawr' mentioned her phone didn't even have one in in the first place.

Richard Aston, · Reply

I also had problems getting at this screw, you really need to move to Step 27-31 of removing the headphone jack.

Don't recommend going any further and messing with the antenna. Then resume to step 34. Likewise ensure you back track when reassembling.

beckerma, · Reply

I too had difficulty removing this screw, mainly because the ifixit bit driver is somewhat fat and gets in the way. Luckily, I had bought the replacement screen from iCracked and their provided screwdriver was somewhat thinner.

Be careful with this and have patience!

I found that I had to remove the 6 side screws and washers completely, because the new front tabs were bent inwards. To reinstall them all, I supported each screw on the up-facing tip of a magnetic screwdriver, then I placed the washer onto the screw with a tweezers, and then I inserted the screw upwards into its hole, never changing the orientation of the screwdriver.

cpwittenberg, · Reply

It is very easy and helpful at the end of this step, to gently push down the screen holders in the 6 spots with screws and washers, that way the screen gently comes out and you don't have to poke with anything.

superedu111, · Reply

When you reassemble the device, be absolutely sure that the digitizer cable is pulled all the way through the slot ...it tends to get stuck since it has a sharp edge for whatever reason. Failing to notice that, the digitizer cable wont reach its socket. But not only that! Pressing the display against the case will introduce a more or less sharp bend to the cable which likely results in a broken digitizer cable, hence a broken digitizer!

Once my screen was removed, a piece of rubber fell out of the phone onto my work surface. I sweated and looked for half an hour, at the frame in my hand and at all the photos in the guide, for a place that it might fit. I eventually gave up, and my phone has been working fine without it, but where is this piece supposed to go?

I had the same exact thing happen to me. I couldn't see where this piece came from either. Just like you, I gave up and reassembled my phone. It works just fine. I still held on to the part just in case, but I don't expect any problems.

djlogic26,

It's been a month now, and I've been using my phone with no problems at all. Battery life is great, it has all sorts of reception, and there are no unusual sounds as the phone is shaken or put under pressure. Whatever that piece is, I feel like it's not important enough to put back in.

Daniel Brauer,

I didn't remember to look inside the iPhone 4S for this piece of rubber but I believe they are present in both AT&T and Verizon iPhone 4's. The rubber wraps around the edge of the main logic board where the display and digitizer cables wrap around. It's not needed for proper operation but may protect the cables from long term flex and wear against the edge of the board.

Wallace Karraker,

When you are putting the new screen on make sure the little wires are pulled all the way through! or else you will be very frustrated 15 steps later and have to go back again.

To add to the last comment, one of the of the digitizer cables was was too short. I disassembled it twice to figure out it was folded. When I straightened it out it snapped. A 12.0 repair turned into over a 100.00 when I had to replace the screen assy. But, still cheaper than a new phone.

If you use an aftermarket replacement, the backlight might flicker until you temporarily disable autobrightness or let it sit for up to 6 hours. There's quite a few comments about this on other forums but figured one here would be relevant. Otherwise, this was great.
