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.

-
-
Pull the blue handle forwards to lock the arms.

Turn the handle clockwise 360 degrees or until the cups start to stretch.

Heat an iOpener and thread it through the arms of the Anti-Clamp.

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.
-
-
-
Pull up on the suction cup with firm, constant pressure to create a slight gap between the screen and the frame.
-
Insert an opening pick into the gap.
-
-
-
Slide the opening pick up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place.
-
Stop near the top left corner of the display.
-
-
-
Re-insert your tool at the lower right corner of the iPhone, and slide it around the corner and up the right side of the phone to separate the adhesive.
-
-
-
Gently pull up on the suction cup to lift up the bottom edge of the display.
-
Pull on the small nub on the suction cup to remove it from the front panel.
-
-
-
Slide an opening pick underneath the display around the top left corner and along the top edge of the phone to loosen the last of the adhesive.
-
-
-
Slide the display assembly slightly down (away from the top edge of the phone) to disengage the clips holding it to the rear case.
-
-
-
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.

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.
