Xiaomi Redmi Note 9S Rear Glass Replacement
- This repair guide is for replacing the damaged rear glass of your Xiaomi Redmi Note 9S.
- When reassembling, you will require replacement adhesive to secure components in place.
Step 1 | Heat the rear glass
Prepare an iOpener by applying it to the back cover for at least two minutes.
- The adhesive underneath should begin to loosen.
Avoid overheating, as this can damage the display and internal battery.
- Alternative methods include using a hair dryer, heat gun, or hot plate.
Step 2 | Insert an opening pick
Secure a suction handle to the bottom edge of the rear glass as close to the edge as possible.
If the rear glass is cracked, the suction handle may not stick — try lifting it with strong tape or superglue the suction handle in place and allow it to cure before proceeding.
- Lift the rear glass with the suction handle to create a small gap between the back cover and the frame.
- In case you have trouble creating a gap, apply more heat to further soften the adhesive — follow the iOpener instructions to avoid overheating.
Insert an opening pick into the created gap.
Step 3 | Slice the adhesive
Slide the opening pick to the bottom right corner to cut the adhesive.
- Hold the opening pick in place to prevent the adhesive from resealing.
Step 4 | Slice the adhesive
Insert a second opening pick at the bottom edge of the phone.
- Slide the new opening pick to the bottom left corner to slice the adhesive.
- Leave the opening picks in place to prevent resealing.
Step 5
If adhesive becomes hard to cut, it may be cooled down.
- Use iOpener for 1-2 minutes to reheat the adhesive.
- Insert a third opening pick at bottom left corner of phone.
- Slide opening pick along left edge of phone to slice adhesive.
- Leave opening pick in top left corner to prevent adhesive from resealing.
Step 6
Insert a Y000 opening pick under the top left corner of your phone.
- Slide it along the top edge, slicing the adhesive as you go.
- Leave the pick in place at the top right corner to prevent resealing.
Step 7
Insert a fifth opening pick under the top right corner.
- Slide the pick along the right edge of the rear glass, slicing any remaining adhesive.
Step 8 | Remove the rear glass
- Remove the rear glass.
- Clean areas with isopropyl alcohol (>90%), then apply new adhesive as needed.
- Rear glass can be secured using pre-cut adhesive or double-sided tape.
- Apply firm, steady pressure to the phone for several minutes after installing the rear glass to ensure a good bond.
