    • Use a spudger to disconnect the fingerprint sensor from the motherboard.

    • Peel the NFC antenna cable off of the metal plate.

    • Use a spudger to lift the motherboard carefully.

    • Remove the motherboard assembly.

    • On the back of the motherboard there is a thermal pad (pink rubber-like gob) for heat dissipation. If you are about to replace the display assembly, and the thermal pad broke or is too dried out, you might want to replace it with a new one.
