Overview
Step-by-step
- 1
Power off the phone
1 minPress and hold the power button, then select Shut Down on the screen. Ensure the device is fully powered off before starting.

Remove the SIM tray
1 minInsert a SIM eject tool into the hole on the right side of the phone. Push firmly to eject the tray and remove it.
- 3
Heat the rear glass
2 minUse a heat gun or hair dryer on low heat to warm the outer edges of the rear glass for about two minutes. This softens the factory adhesive underneath.
- 4
Attach the suction cup
2 minPress a suction cup firmly onto the lower half of the rear glass near the USB-C port. Pull upward gently to create a tiny gap between the glass and frame.
- 5
Insert an opening pick
3 minInsert the tip of a plastic opening pick into the gap created by the suction cup. Slowly slide the pick along the bottom edge to slice the adhesive.

Slice perimeter adhesive
4 minCarefully guide the opening pick around the side and top edges of the rear glass. Reapply heat if the adhesive becomes resistant.
- 7
Lift off the rear glass
2 minGently lift the rear glass off the phone chassis. Note that the power button contacts interface via spring pins, so no ribbon cable attaches the glass directly to the board.

Unscrew the midframe cover
3 minUse a Phillips #000 screwdriver to remove the ten screws securing the plastic midframe and wireless charging coil assembly.

Remove the midframe shield
2 minInsert the flat end of a spudger under the top edge of the plastic midframe shield. Pry gently to unclip and remove it from the device.

Clean adhesive surfaces
3 minMoisten a lint-free cloth with isopropyl alcohol and wipe away residual adhesive from the frame mating surface.

Apply new glass adhesive
3 minAlign pre-cut back glass adhesive strips onto the perimeter of the phone chassis and peel off the protective backing.

Seal the rear glass
2 minAlign the rear glass over the frame and press firmly around all edges. Apply mild heat for one minute to ensure a tight bond.
