Introduction

Use this guide to remove or replace a faulty logic board in your iPhone 6.

It's important to note that each iPhone's logic board and Touch ID fingerprint sensor are paired at the factory, so replacing the logic board will disable Touch ID unless you also install a replacement home button that has been properly paired to your new logic board.

You can also use this guide to replace the Upper Cable Bracket.

Image 1/1: Power off your iPhone before beginning disassembly.
  • Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

  • Power off your iPhone before beginning disassembly.

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

When reconnecting be VERY careful not to over tighten. The connectors on the screen that these 3.6mm Pentalobe screws lock with are notorious for breaking off

Before opening the phone, I gently warmed it using a buckwheat heating pad. This made removal of the adhesive strips (steps 20 to 24) easy.

I put mine back together but mine looks very different than this one. Why is it that when I make a call I cannot hear through the ear piece and have to put it on speaker. Also my screen doesn't go black when my face touches it

Hey Bailey, which repair were you attempting? Is it possible you have a 6s, or maybe a 6 Plus? You may have better luck with faster troubleshooting if you post in our Answer Forum!

Image 1/1: If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone 6.
  • The next three steps demonstrate using the iSclack, a great tool for safely opening the iPhone 6 that we recommend for anyone doing more than one repair. If you aren't using the iSclack, skip to Step 5.

  • If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone 6.

  • Close the handle on the iSclack, opening the suction-cup jaws.

The iSclack opened the iPhone 6 with little effort. I could have given even less opening pressure than I did. Fantastic tool. Worth the investment.

It's never mentioned anywhere that with iSclack even if you save the cables, glass easily detach from plastic frame. When you ri-assembly the phone, this will involve a glass not perfectly adherent to the body. In my opinion is better if you help yourself with a spudger to lift frame from rear case when you are using the iSclack.

Image 1/1: Press a suction cup onto the screen, just above the home button.
  • If you don't have an iSclack, use a single suction cup to lift the front panel:

    • Press a suction cup onto the screen, just above the home button.

    • Be sure the cup is pressed securely onto the screen to get a tight seal.

This is nearly impossible on a screen that is shattered

Erik Madsen - Reply

Try putting a strip of packing tape on the screen. That will make the surface smooth and help keep the suction.

Image 1/1: Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.
  • While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.

    • Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

  • Using a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while continuing to pull up with the suction cup.

  • There are several clips holding the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

Pulling up on the suction cup helped get me started, but what worked for me was pulling up gently while sliding the plastic prybar gently along the seam towards the top of the phone (on both sides), and it came open without having to put excess pressure on the suction.

lauren carroll - Reply

Same here, just open the gap a little with the suction cup and then use the opening tool on both sides.

Tobias - Reply

Along with the suction cup I used some Command adhesive strips to hold the bottom of the phone to a workbench as they easily pull/stretch away when you need to remove them!

Dion Sosa - Reply

Suction cup pictured here is the older version (with ring). I have one from my previous battery replacement on iPhone 5 and used that instead. The new one (gray with blue handle) kept on popping off. Overall, popping out screen was not as hard as it seems with these instructions, but do proceed with caution.

I skipped steps 13-19 and just left the front panel rubber banded while I removed the battery. I just made sure to be careful while removing the adhesive strips so as not to move around the body of the phone too much. Skipping the steps made the whole process much faster and easier.

Can disconnecting the battery connector while power is on ruin the backlight? Or can disconnecting the power connector at a different stage ruin the back light?

mitch Toler - Reply

You should power down the phone before disconnecting the battery. That said, the backlight should be fine. A blown backlight circuit is most commonly caused by disconnecting the display when the battery is still connected.

Image 1/1: Three 1.2 mm screws
  • Remove the following five Phillips screws securing the front panel assembly cable bracket:

    • Three 1.2 mm screws

    • One 1.7 mm screw

    • One 3.1 mm screw

  • Incorrect placement of these screws during reassembly will cause permanent damage to your iPhone's logic board.

Be careful when replacing the screws, not to accidentally put the 1.7mm screw into the center hole, where the 1.2 screw belongs. This can cause "Long Screw" damage, and render your phone unusable.

damianodessgillett - Reply

I don't have the magnetic pad but use duct tape face up in a tray. I write the step number and color of the screw on the sticky surface and let the screw stand heads up on the goo. The screw is presented for the driver when reassembling.

griffn - Reply

Can't stress enough how important it is not to mix up these screws! Using the 1.7mm screw for the lower left fixing will cause "long screw damage" and kill the backlight on the phone. I believe @damianodessgillett made the same point. Wish we could display a small warning message here to be extra careful for future fixers!

kev - Reply

I use a screw ID technique similar to griffn's; I print out the PDF version of the guide, then Scotch-tape each screw type to the guide at the step where the screw was removed. The screws are then distinguished by size and type at the point where they need to be reinstalled.

@girlsrock742 - I'm new here, but from what I've seen, questions like yours don't get answered. I have 2 suggestions:

# Be more specific about what your issue is.

# Make sure you're using the right screwdriver. (Get a magnifying glass & make sure the screwdriver fits nicely in the screwhead.) This guide is included in a guide I'm looking at, and my guide has a comment that #000 phillips is required for the battery connector bracket above, not #00 as documented. (That comment did not convey to this guide....)

Good luck!

Nate Schley - Reply

Thanks to @griffn & @adlerpe! I've updated the tools list to include the magnetic pad, and -- for us infrequent fixers -- I made a note in the intro text to describe the sort of thing you two noted here in place of the mag pad.

Also, to @damianodessgillett & @kev - I've submitted an update to the instructions to add the caution you recommend to the step. Hopefully others will avoid the pain of the Long Screw damage.

It's possible to damage only a slot of flex cable ? I've opened my iPhone 6 but now front camera, speaker and the proximity sensor are not working. I've bought a new flex cabe to test it, but I have to be sure about that.

cruz.giovanni - Reply

I'm so worried I'm going insert the wrong screw. Does anyone have any suggestions to knowing how to properly tell the size of each screw? I bought a screw set and a magnetic pad but still have the same issue. Not knowing the correct placement of each screw. I'd definitely appreciate any help.

Patric - Reply

Hi Patric! We use a set of calipers to measure our screws, failing that you could use a very fine ruler. If you don't have any kind of measuring equipment, line the screws up on the magnetic mat and sort them by size there. Ideally you only have screws from this step! If you are trying to determine the size of all the screws in this guide, it's probably best to get a real ruler/caliper for the fine distinctions.

Do you have to remove the display to replace the battery?

Michael Aguilera - Reply

It's not absolutely necessary to remove the display, I kept my display propped up throughout the operation. Removal of the display doesn't seem to offer any particular benefit, unless you have problems with the adhesive strips.

Adam - Reply

Hi. I messed up with the screws in the cover guard sheet for the display ribbon and my iPhone 6 plus isn't turning on. Does that mean the logic board is dead or the battery ? Should I throw the phone in the garbage can ?

nzf - Reply

I can confirm it's not necessary to remove anything other than battery bracket. If you support the screen against something as in the picture, just make sure you hold the iPhone absolutely still with one hand while pulling out the adhesive strips with the other. I also used a small piece of tape to hold the screen in place against the box while I worked.

I am now a very happy customer and am looking forward to another few years life from my awesome iPhone 6!

Matt Whiteley - Reply

There is no need to do this step. No need to remove these 5 screws. Just make sure the screen is propped up against something strong and this step is unnecessary for the proper removal and re-insertion of battery.

arunhn - Reply

I left the front panel connected and it was much quicker. But, if you have to wrestle with the battery, it is much safer with the front panel removed. If you have worked on a few phone before, I'd try removing the battery with the front panel connected. If the battery is giving you problems(like if you tear the strips and have to heat the backside), you can always come back to this step.

Joel Horie - Reply

I strongly recommend you leave the display connectors alone if you can. My battery came out without a fight, but I found the display connectors to be almost tragically delicate, and I had white lines in the display when I booted it. During the subsequent attempts to remedy that situation, things went down hill and now I'm waiting for an entirely new display to try to rescue the phone from repair oblivion.

kevin hekman - Reply

I also skipped all of the screen-removal steps and had nary a problem. Just rubber band the screen around whatever it is propped against and I believe you'll be fine.

Hello! I put the screws on in the wrong order and I believe my backlight is dead, iTunes still recognizes my phone when I plug it in, but the screen is blank. Is it possible to replace the logic board or is the phone useless forever?

You probably connected the cables wrong, try doing this step again and carefully correct your cables.

June Beltran -

I totally recommend doing this step first before removing the battery connector bracket, it will be much easier and comfortable with the screen out of the way.

Also I recommend drawing the bracket on a piece of paper and place the screws on top of the respective position on the drawing, this way you won't be confused when putting them back.

I accidentally lost a 1.2mm screw while doing a screen replacement. Will this make the phone malfunction in anyway after I close it back up or its fine?

I can not get these electrical connections to reconnect. If there is some secret to this it should be noted. I now have a phone all taken apart and can not get it back together. It makes no sense to only give directions to take a phone apart and not to put it back together.

Hi alyssa. Were you able to connect the cables? I am having the same problem

Veronica del Rio -

regarding cable connects - if two of the ribbon cables are not properly overlapped around each other, then it will appear as if cable #2 will need to plug into the closest jack, which is actually for cable#3. Look at the two connectors carefully - they are opposite gender and can't be interchanged.

David Panak - Reply

This is good advice, and usually the problem people experience here. There is a very specific way the ribbon cables are layered, and if not correct when reassembled, the reach of the cables will cause you to assume which cable goes where and to try to insert the wrong plugs into the wrong sockets. Please do not try to force them. If they don't snap in easily, examine them closely, and you'll see the plugs and sockets are slightly different sizes, with one wider than the other. Better to take care to note how the cables layer during disassembly, or perhaps mark them to avoid this frustration on reassembly.

it is very possible to install flex cables out of order. to most people working on their first screen replacement they do not have the experience to notice that their flex cable connection is different than the dock connection. this causes them to press harder and force the connection into the dock, ruining the connections, if they do not think the they have the cables out of order

I'm with Andrew Midgett. The connectors are just plain different in size and orientation. My phone matches what's shown in the picture above. You can see an example of the replacement part if you search Amazon for "Sanka LCD Touch Screen Digitizer Frame Assembly Full Set Screen Replacement for iPhone 6". And Sanka isn't the only iPhone 6 replacement that looks like that, so no hating on that manufacturer here.

Does this mean that some iPhone 6 phones have one set of connectors and some have a different set? FWIW, the model on the back of my phone says A1549.

PG McLaughlin - Reply

Update: Searching for iPhone 6S instead of 6 on Amazon, I see lots of replacement screens with connectors that look a lot more like what I have and what's shown in the picture above. (One connector has a horizontal orientation, the other is vertical. I can't be sure whether the pins or dimensions match otherwise.) Any wisdom here?

When I was preforming this step, while reassembling, I had to connect the digitizer cable four times. On the last time, before screwing the Front Panel Assembly Cable Bracket on, I reconnected the battery connector and turned my phone on (ensuring that I was careful not to damage any cables!) to ensure that all cables were connected correctly and that the screen was fully functional.

NO NO NO ! i am a professional iphone repairman and i strongly recommend against using ANY tool to disconnect the flex connectors if u slip or use to much force you will damage the connector and may cause permanent damage to the phones logic board rendering it completely UNrepairable! Instead gently use the edge of your fingernail and pry up and the connectors will usually come off with very little effort .

If you still have white lines after you've tried reconnecting the connectors and power cycling. Just do a hard reset a few more times, let the phone stay on and wait a while. As long as it's not damaged, the lines will fade over the next hour or so. Your phone will be as good as new.

Reassembly was harder than other i devices I have worked on. A bench light from the side helped a lot with the first cable, the digitizer. The others went a bit better in this crowded space. I had screen lines when testing it out before closing the top, so reinstalled all four connectors here with the aid of a side light and happily, that worked!

I had the most issues when reassembling with this step. The plastic tool is a fail in my experience since not enough pressure could be applied using it.

Image 1/1: Two 1.9 mm Phillips #00 screws
  • Remove the following screws securing the logic board to the rear case:

    • Two 1.9 mm Phillips #00 screws

    • One 2.3 mm standoff screw

      • Use a small flathead screwdriver to remove these standoff screws.

      • During reassembly, you can use the tip of a spudger to get the standoff screw started.

The standoff screw was difficult to remove because a normal phillips head screwdriver is the wrong shape. I had to use a small flat head screwdriver carefully to get it off.

Matthew Williams - Reply

I absolutely can not get this standoff screw off. Searching the web now for "iphone standoff screw" I see that there are specialized screwdrivers for getting this screw off. I wish I had one right at this moment! Anyway, an improvement to these instructions would be to mention this standoff screw upfront, so that one can be prepared with the right screwdriver before starting this job. I'm stuck at this step right now. A small flathead screwdriver just isn't cutting it.

Hello. I used a 1.5 mm flat screwdriver from iFixit Pro Tech Toolkit. It worked easily for me.

I've been told that the problem with my phone is the logic board. Can any standard logic board be swapped in for a defective one, or are there any additional steps needed to get the phone operational?

is there a way to swap only the memory component instead of the whole thing?

jonesandrew1414 - Reply

Yes, you can, but you will need to have some serious soldering skills. But in theory you can replace the memory chip with another memory chip that has been reprogrammed to fit your phone's serial number.

Anyone an idea, where I can find the logic board?

I have assembled an iPhone 6 and it seems that everything goes fine except the NFC. The phone does not respond to the POS when using Apple Pay. I think there should be some poor connection between the logic board and NFC antenna. If so, which screws should I scrutinise to fix this problem? Thank you.

make sure you have connected the digitizer 1 lcd 2 camera 3 home button is 4 . the camera lead must over lap the lcd cable otherwise the cable retainer will not fit properly because the cable will cover the screw hole of the cover hope this helps.

If someone says you need new logic board, try fixing to board first. Try iPad rehab, iFixLogicBoards, Powerbookmed etc. These logic boards are expensive and sometimes they come iCloud locked :(

I recently dropped my phone and shattered the screen but got it repaired. But I noticed that my screen is sort of an off-white color and my brother said that's because my motherboard took most of the damage when I dropped my phone. But he says that I can't repair the motherboard.

Hi guys,

Two months ago I connected my iphone 6 plus to a cheap charger. The charger blown up. I disconnected the iphone from it. The iphone doesn't work at all. I took it to 3 maintenance shops in my town. They said that the all of the circuits are burnt and they can't fix it.

Is there a way to fix it?

I recently connected my IPhone to an audio jack in a sound system so I could play a song from the phone for a funeral. The audio jack must have fried the phone. :-( I took it to a local repair and they said the motherboard is damaged. All I want to do is salvage pictures and notes. Can I salvage those by replacing the motherboard?

Well you could have them transfer the memory card to the new board but it cost some money and it tedious work

Out of no where, my almost-2-year old iPhone 6 was suffering from very weak wifi, very week bluetooth, and the GPS became out of whack and unusable.

Super thanks to ifixit and their guide for replacing the wifi flex cable! It worked for me and my phone is like new again.

Important note: Be sure to have a screwdriver made for the 'stand off' screw (step 36). The first time I attempted this repair I got to that step and got stuck. A regular flathead screwdriver would not work for me. I had to reassemble my phone, order a special screwdriver for that screw, wait a week for it to arrive, and then attempt this repair again.

Second time was a charm. Got through the steps much faster than the first time, swapped the antenna with a new one, put it all back together... and ta-da! Full strength wifi and bluetooth back again, as well as fully functional GPS. Thank you to whoever put this guide together!

where to buy the logic board

zivad v - Reply

Thank you for this fantastic write up! Worked perfectly. I have a 128gb iPhone 6 and both my navigation, and bluetooth were not working properly. Navigation would be inaccurate to about 300 feet, and wouldn't reroute, both of which rendered it not useful, ever. The bluetooth would only work within a VERY short distance. As in, if it was in my pants pocket that I was wearing, it would often glitch. Also annoying. Some google searches showed that changing the logic board antenna flex cable, solves the problem. Ordered my flex cable from iFixit, and Sure enough, it worked!!! Perfect Nav, and so far no issues with bluetooth. BIG WIN for the internet and ability to search, and find companies like iFixit providing tutorials!!! Thank you!

I have lost all cell service. It either says no service or searching. The connectivity pad on the flex antenna melted and moved and i moved it back. I was able to hit the back of my phone with my hand and it would get service for a little while. Now it just only works on wifi. Any suggestions on what it could be? Does the top flex antenna have anything to do with cell service?

My phone doesn't turn on anymore!! What do I do now? The instructions were really good buT now my phone doesn't turn on. I thought maybe the screen just didn't connect properly so I tried calling it to see if it would vibrate but it didn't. I can't locate it either. And, when I send an iMessage to it, it doesn't show as delivered. So I'm very included to believe the phone just doesn't turn on anymore.

ambrish patel - Reply

Don't panic! If your phone is completely dead, it is very possible that the battery isn't connected. Check the connector in step 12 to ensure that you correctly replaced this connector. If this connector didn't seat correctly, then the phone will be completely dead. Let us know if this fixes it! If not we can continue to troubleshoot.

Scott Havard -

I followed all the instructions listed to replace the faulty antenna. Everything went great with that repair: my wifi/gps/bluetooth issues were solved! However, I lost audio through the earpiece (I can still use the speaker) and the forward facing camera went off. After trying to disconnect and reconnect the connections before you remove the screen entirely, but the issue persists. Could someone please help? I'm clearly missing something.

Becca - Reply

Becca, given the description of your problem it definitely sounds like one of those connectors still isn't sitting properly. As long as you were gentle through the steps, it is unlikely that any connector is broken. As long as this is true, it is just a matter of you going in and making sure that the press connectors are all secured in their spots. I always struggle getting these cables connected, so I wouldn't be surprised if if takes you a couple tries to get everything connected properly.

barakatmarket - Reply

Unfortunately, that's normal—each iPhone's logic board and Touch ID fingerprint sensor are paired at the factory, so replacing the logic board will disable Touch ID unless you also install a replacement home button that has been properly paired to your new logic board.

Hi,

Is it a fact that in every case of changing the Logic Board Antenna Flex Cable the touch ID doesn't work anymore?

once you have the mother board out, flip it around and swap it out, but be careful, these connectors are very fragile and make sure not to damage the connectors

Thank you so very much, I am so grateful to have stumbled across your great site. I used your iPhone 6 Plus tear down to remove a broken piece of charging cable tip that was wedged in the charging port, what a relief when I was able to remove it by removing the port. Thank you for all the hard work that went into this site.

i was doing a flex cable replacement, and i followed all the steps. i was scared that i messed up the motherboard cause of the screw configuration, but when i connect the battery i get put into the apple logo bootup cycle, it never boots up but the screen is fine. did i mess up somewhere else or what?

Sam B - Reply

So glad I stumbled across this. I almost went out and bought a new phone since the gps was always inaccurate. $20 and 2 hours later my gps is working accurately again. Like people have said before I recommend taping the screws down with the layout on a piece of paper. Also, in my case this video on youtube was very help: https://www.youtube.com/watch?annotation.... He has other videos that could also be helpful for this.

Replaced the antenna flex board by following this guide. I bought the part ( http://tiny.cc/xmbbly )with the tools and it took about an hour to complete. I stuck all the screws to a sheet of paper with tape in the order I took them out. That helped a lot! Now, GPS and Bluetooth are both working well. Something that hasn't been the case since I got the phone from Craigslist. Thanks for an excellent resource.
