Redmi Note 9 Pro Rear Glass Replacement
This repair guide is for replacing a broken rear glass on the Xiaomi Redmi Note 9 Pro smartphone. Replacement adhesive will be required to secure components properly during reassembly.
Step 1 | Heat the rear glass
Prepare an iOpener and apply it to the rear glass for at least two minutes to loosen adhesive.

Avoid overheating the phone as the display and internal battery are susceptible to heat damage.
Step 2 | Insert an opening pick
Secure a suction handle to the rear glass's bottom edge, near the edge.
If the rear glass is cracked, 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 frame.
- Apply more heat if necessary, following iOpener instructions to avoid overheating, to further soften the adhesive.
Insert an opening pick into the created gap and slide it to the bottom right corner to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.
Step 3 | Slice the adhesive
- Insert a second opening pick at the phone's bottom edge.
