Xiaomi Redmi Note 7 Loudspeaker Replacement
Not replacing the adhesive seals during reassembly may compromise water protection.
- Follow this guide for loudspeaker replacement on Xiaomi Redmi Note 7.
- Purchase new adhesive for reattaching components during reassembly.
Step 1 | Loosen the rear glass adhesive
Apply a iOpener to the rear glass and heat it for at least two minutes.
- The iOpener should loosen the adhesive underneath.
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 badly cracked, cover it with clear packing tape or use strong tape instead of the suction cup.
- Alternatively, superglue the suction cup to the rear glass if necessary.
Apply caution when using heat as excessive overheating can damage the iOpener and surrounding components.
Lift the rear glass with the suction handle to create a small gap between the glass and frame.
- If trouble creating a gap, apply more heat while following the iOpener instructions.
- Insert an opening pick into the created gap.
Slide the opening pick to the bottom right corner to carefully slice the adhesive without causing further damage.
Step 3 | Slice the bottom edge adhesive
Insert another opening pick and position it at the bottom left corner.
- Slide it across to begin slicing the adhesive.
- Leave both opening picks in place, as removing them will cause re-adhesion.
Step 4 | Slice the lefthand-side adhesive
If adhesive becomes hard to cut, it may have cooled down — use iOpener to reheat.
- Insert a third opening pick into the bottom left corner of the phone.
- Slide the opening pick along the left edge to slice the rear glass adhesive.
Leave one opening pick at top left corner to prevent adhesive resealing.
Step 5 | Slice the top edge adhesive
Insert a fourth opening pick under the top left corner of the rear glass.
- Slide the opening pick along the top edge of the phone to cut the rear glass adhesive.
- Leave the opening pick in the top right corner to prevent re-adhesion.
Step 6 | Slice the righthand-side adhesive
Insert the fifth opening pick into the top right corner.
- Slide the pick along the right edge to cut remaining adhesive.
Do not attempt to fully remove the rear glass yet, as the fingerprint sensor remains connected.
Step 7 | Open up the phone assembly
Avoid tensioning the fingerprint flex cable while folding.
Fold the rear glass to the left side, similar to opening a book.
Step 8 | Unfasten the screws
Remove the Phillips screwdriver and take out the three screws (3.3 mm long) securing the connector cover.
- Use a Phillips screwdriver for this task.
- The screws are 3.3 mm long.
Step 9 | Remove the connector cover
Use a pair of tweezers to remove the connector cover.
Step 10 | Disconnect the battery
Insert the flat end of a spudger under the battery flex cable and gently pry it loose from the motherboard.
Step 11 | Peel the protective foil off
Separate the back cover, including the fingerprint sensor, from the phone assembly for easier handling.
- Use a pair of tweezers to carefully remove the yellow protective foil from the ZIF connector.
Step 12 | Open the ZIF connector
Bring the black flap on the ZIF connector into an upright position using the pointed end of a spudger.
Step 13 | Disconnect the fingerprint flex cable
Use a pair of tweezers to pull the fingerprint flex cable straight out of the ZIF connector.
Step 14 | Unfasten the screws
Remove the screws securing the loudspeaker assembly using a Phillips screwdriver.
- The screws are 8 in total, each 3.3mm long.
Step 15 | Remove the loudspeaker assembly
