Xiaomi Mi 8 Motherboard Cover with NFC Replacement - Xiaomi Mi 8

Apply a iOpener to the rear glass for at least two minutes.

Position the iOpener so that it heats the entire length of the rear glass.
Let it heat the adhesive beneath the edges for the full two minutes before proceeding.

Secure a suction handle to the lower edge of the rear glass.

If the rear glass is cracked, use strong tape or superglue to secure the suction handle.
Lift the rear glass with the suction handle to create a gap between the glass and frame.
Insert an opening pick into the gap.

If the glass does not budge, apply more heat as per iOpener instructions to avoid overheating.

Slide the opening pick to the bottom right corner of the phone.

Insert another opening pick near the bottom left corner and gently slide it downward.
Keep both opening picks in place, as removing them can allow the adhesive to seal again.

Insert a third opening pick at the bottom left corner.

Slide the opening pick along the side of the Xiaomi Mi 8, starting from the bottom left corner to cut the adhesive.

Avoid damaging the fingerprint flex cable; only insert the tip of the opening pick, and do not push too far.

If you accidentally insert the opening pick too deep, it may cut the cable.

As the adhesive cools, it will harden; if needed, use your iOpener to reheat and soften the adhesive for easier removal.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Insert opening pick 4 under top-left corner of rear glass.

Insert a fifth opening pick at the top right corner of the phone.

Do not attempt to remove the rear glass completely yet — risk of damaging the fingerprint flex cable.

Lift the rear glass carefully, then fold it towards the left side to expose the fingerprint flex connector.

Use a spudger to disconnect the fingerprint flex cable.

Remove any remaining adhesive from the phone and clean the glued areas with isopropyl alcohol and a lint-free cloth before reassembly.

Apply pressure to the rear glass for several minutes after installation to form a good bond.

Use a stack of heavy books on top of the phone to apply even pressure.

Remove the motherboard cover.

Insert the opening pick along the right edge of the motherboard cover.
Sideways twist the opening pick, prying the motherboard cover loose and lifting it slightly.

Careful removal of the motherboard cover, which includes the NFC antenna, is necessary.

Remove the screws holding the motherboard cover in place using a screwdriver.
Gently lift and remove the motherboard cover from its location.
