Follow this guide to remove and replace the logic board for the iPhone 8.
Note: 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.

Power off your iPhone before beginning disassembly.
-
Remove the two 3.5 mm pentalobe screws on the bottom edge of the iPhone.
-
-
-
Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.
-
Use a hairdryer or prepare an iOpener and apply it to the lower edge of the phone for about 90 seconds in order to soften up the adhesive underneath.
-
-
-
Apply a suction cup to the lower half of the front panel, just above the home button.
Even with using high heat from a blow dryer, I had to put the suction cup over the home button or the bottom edge wouldn’t lift at all. That waterproof adhesive is incredibly strong.
-
-
-
Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
-
Insert an opening pick into the gap.
Just completed a smashed screen replacement, this is probably the most time consuming part. Used packing tape to cover the screen to help create a suction surface (had to replace it a couple times because it pulls away after a purple good pulls ) Used consistent heat for about 5 minutes, then stuck a pick in the tiniest opening… and pry pry pry!

-
-
Open the iPhone by swinging the display up from the left side, like the back cover of a book.
-
Lean the display against something to keep it propped up while you're working on the phone.

Remove four Phillips screws securing the lower display cable bracket to the logic board, of the following lengths:
-
Two 1.3 mm screws
-
Two 2.8 mm screws
-
Remove the bracket.
Not Y000 this time haha
It is not ideal, but possible for these screws.
using the repair kit i purchased with my screen replacement, i am currently having issues removing these screws with the PH000. please help
I was too, thankfully I had another set that contained the PH00 bit, that worked great for me.
Ok. My screw is stuck. How do I remove it? Philips head is stripped.
Solved it myself. Firm pressure did the trick.

Use the point of a spudger to pry the battery connector out of its socket in the logic board.
-
Bend the battery connector cable slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.
Make sure you pry the battery connector off from the right hand side as shown in the picture. Theres a delicate component on the logicboard near the battery connector called a Mosfet which is linked to the battery charging software. If you knock it off accidently you’ll loose battery charging and the phone will boot loop and youll need to have it re-soldered back on.

Remove the three 1.3 mm Phillips screws securing the bracket over the front panel sensor assembly connector.
-
Remove the bracket.
If you are replacing the adhesive liner, the remaining release liner strips will interfere with the two outer screws. I had to cut a working section out of the liner at each location and move it aside with the spudger.
This part is throwing me for a loop. Having difficulty finding the read head for these screws. Is it the same size as the two small 1.3mm screws in step 12?
ended up getting it with the PH000, I must of just been rushing it.
My bracket looks different and none of the screw heads I have fits.
These screws did not stick to the magnetic screwdriver. Extremely difficult to get them back in place - but with some patience i succeeded :)

Remove the display assembly.
Hi ifixit, if you find my method dangerous, please remove it.
After Step 17, I skipped Step 18 to Step 28.
At Step 29, I lifted up the four adhesive black pull-tabs to expose the white adhesive side. Next, I use hot air gun and blow on the back cover of the iphone for about a minute (maybe a hairdryer will work too) .
Warning: Don't overheat the iPhone, or you may accidentally ignite the battery.
I think the temperature was around 60 DegC.
Extreme Caution: Do Not overheat. I use my hand to gauge the hotness. Careful not to burn yourself or the board.
I was able to pull out all the white adhesive tapes easily as the adhesive soften.
DO NOT TRY this method if you are a novice or inexperience! I am not responsible if you hurt yourself or damage your iphone!
Hey John! I’m glad the repair worked out for you!
From our research, applying heat does soften the adhesive strips, but it also causes them to lose structural integrity and break more easily. That’s why we normally suggest using heat after the strips are already broken. Removing the Taptic Engine definitely takes a few extra steps, but we feel that it gives fixers the best chance of pulling out the adhesive strips intact.

Insert a SIM card eject tool, bit, or a straightened paperclip into the small hole in the SIM card tray.
-
Press to eject the tray.

Use the flat end of a spudger to disconnect the camera cable connector by prying it straight up from its socket.
-
-
-
Remove the two screws securing the rear-facing camera bracket:
-
One 3.0 mm standoff screw
-
One 3.1 mm Phillips screw
The screw and standoff are the other way round in this step. The photo shows the small screw removed and the standoff securing the logicboard is circled incorrectly. Also you may find that the standoff screw is not magnetic, making it a little tricky to replace!
Hi Michael,
You are correct; thanks for catching that! The original image was correct, and for some reason the image was updated, and no longer correct. I have reverted it back to the original image.

Remove the two screws securing the upper cable bracket:
-
One 2.9 mm Phillips screw
-
One 1.3 mm Phillips screw
Logically - one wouldn’t need to take out all these things to take out something at the bottom of the phone - but in order to get good access to it, you must remove the logic board - which is long and all the way up at the top connected to the antenna. Follow the steps - it works.
-
-
-
Remove the three Phillips 1.3 mm screws securing the top left antenna component.
-
-
-
Remove the two Phillips screws securing the grounding clip at the top left edge of the logic board:
-
One 1.5 mm Phillips screw
-
One 2.6 mm Phillips screw
-
-
-
Remove the grounding clip.
what happen if don't put this part?
Hi Albert,
It’s hard to tell. Most phone functions will probably work, but you may start getting quirky problems.
If it comes out it must go back in *no spare parts *

Remove the three screws securing the motherboard:
-
One 1.8 mm Phillips screw
-
One 2.5 mm standoff screw
-
One 2.2 mm standoff screw
The One 1.8 mm Phillips screw was buried under some gasket material. It took some twezzer work to get that material off.
this is probably the most difficult part because the ‘top 2.5 mm on my version was under a piece of ribbon cable that had to be pulled back. Also notice - this picture is inverted. So the locations are reversed (obviously for clarity)

Use the point of a spudger to pry up and disconnect the Wi-Fi diversity antenna cable.

Hello evryone. Do I need a new touch ID that fits the motherboard or can I use my old touch ID?
The motherboards that are for sale, sell with touch ID and without. That`s why I am asking.
Hi Sebastian,
Yes, the Touch ID is paired with the motherboard. In order to keep Touch ID functionality, you have to use the fingerprint sensor that comes with the replacement.
can i use this process two switch a logic board from a working i phone to one that is icloud locked?
That’s why I’m here
Hi Kenneth,
The phone’s “identity” is based off of the logic board, so switching a logic board will remove the iCloud lock—if the replacement logic board is not locked. Note that the Touch ID hardware is paired each logic board.
It may work but the card to be replaced needs to be unlocked with iCloud.
i have an iphone 8 plus icloud locked ,is it possible that if i change the motherboard with a new one so moblie will again start and work as before .please brief me about this…
Hi Malik,

o novo também precisa ser desbloqueado para que tudo funcione
where can i buy the motherboard and Touch ID?
on aliexpress
just how long are those screws- i turn and turn and turn and the lift off is soooo slight, seemingly insignificant…
