Step 1 – Power Off & Prepare

Turn off the phone and remove the SIM tray before starting the repair.

Step 2 – Remove the Back Cover

Gently heat the edges of the back cover to soften the adhesive.

We’re using a heating pad — place the back cover side on the pad, select Mobile Phone Heating, and allow the cycle to complete.

Alternatively, you may use a heat gun or hairdryer.
Avoid overheating — too much heat can damage the back cover or internal components.

Use a suction cup at the bottom edge to make a small opening.
Insert a plastic card pry tool into the gap and slowly slide around the edges to separate the adhesive.
Take your time — gentle pressure is key.

Once the adhesive is loosened, lift and remove the back cover.

Step 3 – Remove the Mid-Frame

Check again that the SIM tray is removed.

Disconnect the fingerprint/power button connector plug.

Remove all 15 screws securing the mid-frame.

Use a plastic pry card and carefully work around the edges to release all clips holding the mid-frame in place.
This step requires patience — avoid bending the frame.

Lift the mid-frame once all clips are free.

Step 4 – Replace the Loudspeaker

The loudspeaker module is built into the mid-frame.

Remove the faulty speaker from the frame.
Place and secure the new loudspeaker module in the same position.

Make sure the speaker sits flat and properly aligned inside the mid-frame housing.

Step 5 – Reassemble the Phone

Place the mid-frame back onto the phone.

Reconnect the fingerprint button connector plug.
Reinsert the SIM tray.

Secure the mid-frame by tightening all 15 screws.
Ensure all clips are properly locked before tightening the screws fully.

Before installing the back cover, check the adhesive.
If it’s weak, apply B7000 glue or replace it with new double-sided adhesive.

Press the back cover firmly onto the frame.

Use bonding clips to hold everything in place.
If clips aren’t available, rubber bands will work.
Leave them on for some time to ensure proper bonding.
