简介
Follow the steps in this guide to replace the logic board in an iPhone 6s.
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 for reference to replace the logic board EMI shield stickers.
你所需要的
-
-
Remove the two 3.4 mm P2 Pentalobe screws on the bottom edge of the iPhone, on either side of the Lightning connector.
-
-
-
If you don't have an Anti-Clamp, follow the next three steps to use a suction handle.
-
Apply mild heat to the lower edge of the iPhone using an iOpener or hair dryer for about a minute.
-
-
-
Gently grasp the display assembly and lift it up to open the phone, using the clips at the top of the front panel as a hinge.
-
Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone.
-
Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.
-
-
-
Remove two Phillips screws securing the battery connector bracket, of the following lengths:
-
One 2.9 mm screw
-
One 2.2 mm screw
-
-
-
-
Remove the following four Phillips screws securing the display cable bracket:
-
Three 1.2 mm screws
-
One 2.8 mm screw
-
-
-
Use the flat end of a spudger to disconnect the rear camera from its socket on the logic board.
-
-
-
Insert a SIM card eject tool or a paperclip into the small hole in the SIM card tray.
-
Press to eject the tray.
-
-
-
Remove the two 2.3 mm Phillips screws securing the upper component cable connector bracket.
-
-
-
Remove the following five Phillips screws securing the top left Wi-Fi antenna:
-
Two 1.5mm screws
-
One 2.3 mm screw
-
One 1.9 mm screw
-
One 2.0 mm screw
When tightening the screws again, make sure the screw marked in green and yellow are tightened, it can cause distortions in Apple Pay and NFC functions

-
Use the pointed tip of a spudger to disconnect the antenna cable from its socket on the upper right corner of the logic board.
It is still recommended to disconnect the antenna in this step as it will allow some slack you may need but tugging or pulling on the antenna cable down at the speaker could still damage it so be patience. Also lift on the connection from the metal portion as lifting from the cable could cause it to snap.

Be super careful here, pry the cable by the brass connector so as not to snap it off
During reassembly: be aware that the replacement antenna connector (the one that comes as part of the lightning port assembly) might be a very snug fit here. It probably took me close to 10 minutes to get mine on. Thankfully the little sucker is stronger than it looks, or else I would have smushed it flat multiple times. You’ll know that you finally have it when it lightly snaps in place.

Insert the flat end of a spudger underneath the Lightning connector ribbon cable. Lift up to disconnect it from its socket on the logic board.
Reassembly: A lot of adhesive held this cable down. Had difficulty getting this ribbon cable reconnected to the socket; it kept popping back up. I think the antenna cable was not exactly where it needed to be, and I had to mess with logic board a bit to make sure the antenna cable was wedged down where it needed to be.
Unless you are replacing the speaker you may skip to step 46 as removal of the logic board is not necessary.

Gently pull up on the antenna cable to de-route it from the two clips on the right side of the logic board.
nope, don't bother taking the logic board out if your just replacing the lightning connector. when removing the speaker in the steps after you can just fold it over to the side leaving it connected by the antenna. obviously not very professional but saves a very lot of messing with the 6s's stupid wee plastic clips, brackets and what not.
Thanks friend!!

Wish I had read this comment earlier. Had a bear of a time reconnecting this antenna cable.

Remove the NFC bracket.
Именно эта деталь отвечает за нормальную работу ApplePay, при возникновении ошибок часто является причиной, но не всегда.
“This particular part is responsible for the normal operation of ApplePay, when errors occur it is often the cause, but not always.” Translated this comment into english because I found it very helpful and figured other english speakers would find it helpful to know as well.
Does this also have to do with Airdrop?

Remove the following two Phillips screws:
-
One 2.5 mm screw at the top of the logic board
-
One 1.4 mm screw set into the upper edge of the rear case
For anywhone who struggles with the orange screw: you don’t need to remove it. When removing the logic board, slide it a bit to the bottom to get it from under the clip, and when re-inserting the logic board, slide it back under the clip. This is very easy and no issue

Remove the final three screws securing the logic board to the rear case:
-
One 1.9 mm Phillips screw
-
One 2.5 mm hex nut
-
One 1.8 mm Phillips screw
The tool to remove the hex standoff screw WASNT included in the recommended parts list. A hex driver bit WAS included; however the hex screw needs to be removed using a socket type bit. I removed it using the tweasers as pliers.

You're right, we listed the wrong driver type. It's listed correctly now—the 2.5 mm nut driver is the tool you want.
For some reason the 2.5 mm nut driver in my iFixIt tool set does not work. I think the nut is a bit too shallow (short) to fit into the driver itself
Hi Ray! If you think you have a faulty bit, please don’t hesitate to contact customer service, they’ll take care of you!
I found the same problem with the 2.5mm nut driver in my, non-iFixit, precision set. The nut is too shallow to engage with the hex socket because of the shape of the rounded edges at the mouth of the socket. Managed to overcome this by carefully re-engineering the socket with a diamond flat file ie filing it to remove the rounded edge and leave the hex opening flat and square. Worked perfectly after this.
The funny thing is that for some reason the pentalobe bits seem to let the screw nut go out and screw back in.

The pentalobe driver works perfect with the 2,5 hex nut. Much thanks for the tip: saved me lots of time since I didnt have the appropriate driver handy !
I simply used a pair of long-nosed pliars
Beware. The difficult part isn’t unscrewing the nut, it’s getting it back in again … especially if you don’t have the correct tool.
For the 2.5mm Hex Nut a pair of needle nose pliers and get it started with a unscrewing motion just make sure you don't hit the board itself I could't get it fully out with the pliers just using your fingers to unscrew it fully. Screwing it back it was similar just using the pliers to screw it back in great alternative to using the driver bit however wouldn't recommend it in the long term.

Insert an opening pick below the lower edge of the logic board, between the board and the loudspeaker.
-
Use the opening pick to gently lift the logic board out of its housing.
-
Remove the logic board.
On reassembly, be sure the audio control cable isABOVE the logic board when you place it.
Thank you for the detailed instructions. They were very easy to follow. Hope it works; fingers grossed.

So all the logic boards come with the components installs? Like the High band PAD, power amplifier avago, power amplifier Skyworks, power amplifier TriQuint, LTE modem Qualcomm, and lastly the Apps processor Apple SoC stacked on Elpida RAM. Here I thought you had to buy them.
I'm also assuming that some don't. I would like to know that alternative.
Yup! The SSD is a flash memory chip hidden underneath an EMI shield on the logic board. You can see it in our teardown.
Um, no, actually the NAND/ssd/flash/storage chip is the big Toshiba one in the middle, it’s the one next to the line of capacitors, and is not under the shields. there are shields on either side of it. Look at the teardown page you linked to yourself and you will confirm what I’ve said.
great guide worked perfectly, had some minor water damaged internals with a completely good logic board, replaced it in a 16g pos basically have a brand new 128g 6s

Great instruction. The only thing I had a problem with on my 6s motherboard removal was not knowing how to remove one end of the single black wire that rides along the left edge for about 4 inches (when viewed with the screen upside down and with bottom down. I ended up severing the wire at the bare junction about half way of the wire length. Hope that it is not a coaxial cable!
Great instruction set.

I just cut, soldered, and added shrink tubing, and 3G signal strength is 3-4 dots, after reinstall. I don't believe it is a coax...
if my 6s logic board is water damaged, would replacing this make it work again? i still have my original home button and everything, i know apple pairs the logic board with the home button for touch id security purposes. so will i still be able to use my apple/touch id if the logic board is different?
If your logic board has water damage, it's not necessarily gone forever. For relatively minor water damage, give this guide a try. If that doesn't do the trick, a professional repair tech with an ultrasonic cleaner and board-level repair skills can probably still bring it back to life. If you do end up replacing the logic board, then yes, you will lose Touch ID functions unless you also purchase and install the home button that was originally paired to the new logic board. Good luck!
Hi, I know nothing of phones or repair, but am trying to find out if I can recover the data on my iphone 6s. It hasn't been opened yet but due to the nature of the "bend" in the phone, a "tech" felt the motherboard was likely cracked (he didn't open it, just decided this based on that bend the fact it won't power on/ charge, though it was charged before it got bent). I would love to save my iPhone, but I'm most concerned about the pictures and texts that I have on this phone. Anyone have any suggestions? I would be afraid of replacing it outright if that data is stored there. I couldn't afford to replace the phone with another iphone right now, so when I plug back in it will be with a cheaper Android. Thanks!
Great instruction set. Thank you Evan for taking the time to make this guide

Where may I purchase a new logic board for an iPhone 6s? When replacing the Logic Board, is it required to replaced the home button as well?
So I was trying to replace my screen so I turned it off and followed a video online. While i was trying to plug in the display cable, it conducted electricity and it produced smoke. It seems like I burned parts of the display cable socket. Is there an easy fix for replacing this or would I need to buy a whole new logic board with everything included? My phone still seems to turn on and I can feel the vibration from the ring/silent switch.
@dank_00 This happens when you short the pins on the display cable socket while leaving the battery connected. The little puff of smoke was your backlight filter getting fried. (For future reference, on any mobile electronics repair, you should always disconnect the battery before you start and don’t reconnect it until you’re done.) You don’t need a new logic board, as this is a pretty straightforward repair for a shop with the right skill and equipment. But it isn’t a DIY. You’ll need to find someone who does board-level repairs (a.k.a. microsoldering). Good luck!
Hii icloud lock khul jayega yes or no
I ended up with a similar board malfunction on my behalf. My goal was to unscrew the logic board and test it with a new battery since the battery it came with is stuck to the logic board I thought gee, its easier to remove the logic board, I didn’t do it on a ESD surface it was on my bed. and when I connected to logic board to a working battery I forgot to reconnect the power button connector sleep/wake button. I only connected the battery D.C. connector. I’m afraid that I did something really bad to the LB, the smoke came from the front of the logic board under the top metal heat shield cover plate. Not the bottom of mother board with sticky heat shield stickers. There was no sign of water damage, I should’ve took a picture of the mother board before I worked on it to have a record of working components from the before and after the smoke appeared. Did I mess up because I failed to connect the power, sleep/wake button connector to the mother board after I had connected the battery D.C. connector to board?
Hello sir I'm buy a new logic board iPhone 6s 32GB so this board fully software loaded ef u know please reply me ??
By replacing the motherboard and Homebutton I’ll completely transfer the phones “content” to another one, right? So if the remaining space on the phone is getting less I could replace it with the motherboard of another motherboard from the same iPhone model. I just need to transfer the corresponding homebutton too, as TouchID only works with its original motherboard.
Do I need to replace other parts when swapping the motherboard and home button from one iPhone 6s to another to upgrade my available capacity (16BG -> 64BG)?
I don’t want to want to buy a new phone if I could “recycle mine with a bigger space. If you’re wondering why am I not just buying a working iPhone 6s, its because it is cheaper to get the spare parts from a used phone with maybe a cracked screen or a broken camera. Furthermore I am saving a phone from getting thrown away.
Thank you a lot for your responses. Cheers!

Greetings from Switzerland. Thanks for the great guide. Just successfully replaced a water damaged screen using this, after also removing the motherboard to check for water damage. Phone works like new again. Just have to do the home button replacement to restore touch ID. Kudos to you guys.
