Xiaomi Redmi Note 11 Pro Charging Board Replacement

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

• Alternatively, use a hair dryer, heat gun, or hot plate, but exercise caution to avoid overheating the phone.
• Note: The display and internal battery are prone to heat damage.

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.

• Lift the rear glass with the suction handle to create a small gap between the back cover and the frame.
• If you're having trouble creating a gap, apply more heat to further soften the adhesive. Use caution: follow the iOpener instructions to avoid overheating.

• Insert an opening pick into the created gap.
• Slide the opening pick to the bottom right corner to slice the adhesive.
• Leave the opening pick in place to prevent resealing of the adhesive.

Insert a second opening pick at the bottom edge.

• Slide it to the bottom left to cut the adhesive.
• Leave both picks in place to keep the adhesive from sealing again.

Adhesive may cool down and become hard to cut, use iOpener for 1-2 minutes to reheat.

• Insert a third opening pick at bottom left corner of phone.
• Slide opening pick along left edge to slice adhesive.
• Leave pick in top left corner to prevent resealing.

Insert a fourth opening pick into the top left corner of your phone.

• Slide the opening pick along the top edge to cut through the adhesive.
• Leave the opening pick in place at the top right corner to prevent resealing.

• Insert a fifth opening pick under the top right corner.
• Slide it along the right edge of the rear glass to cut the remaining adhesive.

If there's still resistance, use an opening pick to separate any remaining adhesive around the edges.

Remove the rear glass.

• Clean the relevant areas with isopropyl alcohol (greater than 90%).
• Apply new adhesive to cleaned areas as needed.
• Secure the new back cover using either pre-cut adhesive or double-sided tape.

Apply strong, steady pressure for several minutes after installing the back cover — improper adhesion can lead to damage and leakage.

• Use a stack of heavy books for additional pressing pressure, if needed.

Do not insert the SIM eject tool into the microphone holes.

• Insert a SIM card eject tool, SIM eject bit, or straightened paper clip into the hole on the SIM tray at the bottom edge of the phone.
• Press directly into the hole to eject the SIM card tray.
• Remove the SIM card tray.

If you insert the tool into a microphone hole, do not worry; damage is unlikely.
