Xiaomi Redmi Note 8 Rear Glass Replacement

To avoid damage to the display and internal battery, carefully apply heat only as needed.

• Use an iOpener or alternative heating tool (hair dryer, heat gun, or hot plate) to loosen adhesive underneath rear glass.
• Apply heat for at least two minutes, but do not overheat the phone.

Secure a suction handle closely to the rear glass's bottom edge.

If the rear glass is cracked, it may not stick; try using strong tape or superglue to hold it in place while it cures.

• Lift the rear glass with the suction handle, creating a small gap between the back cover and frame.
• Apply more heat if needed to soften the adhesive further (but avoid overheating).

Insert an opening pick into the created gap.

Slide the opening pick to the bottom right corner to slice the adhesive, then leave it in place.

Insert a second opening pick at the phone's bottom edge.

• Move the pick towards the bottom left corner to cut through the adhesive.
• Leave both picks in place to stop the adhesive from resealing.

If the adhesive becomes difficult to cut, it may have cooled down.

• Reheat the adhesive using your iOpener for one to two minutes.
• Insert a third opening pick at the bottom left corner of your phone.
• Slide the opening pick along the left edge to cut the adhesive.
• Leave the pick in the top left corner to prevent resealing.

• Insert an opening pick under the top left corner.
• Slide it along the top edge to cut the adhesive.
• Leave the opening pick in the top right corner.

Insert a fifth opening pick under the top right corner.

• Slide the pick along the right edge of the rear glass to slice remaining adhesive.
• Do not attempt to fully remove the rear glass yet, as the camera cover and fingerprint assembly is still attached.

Be cautious not to strain the finger print cable while folding the rear glass.

• Fold the rear glass to the right side of the phone assembly, similar to opening a book.

• Disconnect the fingerprint reader using a spudger, lifting the connector straight up.

• Be careful not to damage the connector or the socket — risk of permanent failure.

• Remove the rear glass assembly.

Apply a preheated iOpener to the fingerprint reader on the rear glass assembly for 1 minute.

• The iOpener should loosen the adhesive underneath.

Insert an opening pick under the fingerprint reader.

• Slide the pick along the edge of the reader to separate it from the case.
• The fingerprint reader cable is held in place by a thin layer of adhesive. Use the pick to loosen this.

Remove the fingerprint reader.

• Clean relevant areas with isopropyl alcohol (>90%) and reapply new adhesive where necessary.
• Apply strong, steady pressure to your phone after installing the rear glass to ensure proper bonding
• Secure a new rear glass using pre-cut adhesive or double-sided adhesive tape.
