Overview
Step-by-step
- 1
Power Off Tablet
1 minPress and hold the power and volume down buttons to bring up the power menu, then select Power Off. Ensure the device is fully shut down before proceeding.

Remove MicroSD Tray
1 minInsert a SIM eject tool into the small hole on the side frame. Push firmly to eject the card tray and set it aside.

Heat Display Perimeter
3 minUse a heat gun or hair dryer to warm all four outer edges of the screen for two to three minutes. Heating softens the tough adhesive holding the large display to the aluminum frame.

Attach Suction Cup
1 minPress a strong suction cup onto the glass near the top edge close to the notch camera. Engage the suction lever to secure a firm grip.
- 5
Insert Opening Pick
2 minPull up gently on the suction cup handle to create a small gap between the glass and frame. Insert a thin plastic opening pick into the gap.
- 6
Slice Top Adhesive
3 minSlide the pick carefully along the top edge of the tablet to cut through the adhesive layer. Keep the pick depth under 3mm to prevent damaging sensors.

Slice Side and Bottom Adhesive
4 minInsert additional picks along the sides and lower edge. Gently slide them around the entire perimeter to fully release the screen bond.
