Step-by-Step Charging Port Board Replacement

Step 1: Turn Off the Phone and Remove the SIM Tray

Before starting, turn off the Xiaomi Redmi Note 10 or Redmi Note 10S.

Remove the SIM tray before beginning the disassembly.

Step 2: Remove the Back Cover

The rear cover is secured with adhesive, so gently heat around its edges until the adhesive becomes soft.

A heat gun is used in the repair.

Carefully work around the edges. Once the adhesive has softened sufficiently, use a suction cup to lift the back cover.

Insert a plastic card pry tool between the back cover and the body and gently work around the edges to cut through the adhesive.

Alternatively, a heat pad or hairdryer can be used to soften the adhesive.

Once the adhesive has been separated, remove the back cover.

Step 3: Remove the Camera Lens Frame

Next, remove the camera lens frame.

Undo the four screws securing the camera lens cover.

Once the screws are removed, lift the camera lens frame using a pry tool.

Step 4: Remove the Midframe

Next, remove the midframe by undoing the 13 screws from the top and bottom sections.

After removing the screws, use a plastic card pry tool to create an opening and separate the frame.

Carefully work around the edges to disengage the plastic clips.

Be careful while lifting the frame because the fingerprint flex is attached to the midframe.

Disconnect the fingerprint flex cable to release the midframe from the phone body.

Also disconnect the battery plug from the right-hand side.

Step 5: Remove the Main Ribbon Flex

Next, remove the main ribbon flex.

Disconnect it from both ends and take it out of the phone.

Step 6: Remove the Speaker Buzzer

Next, remove the speaker buzzer from the bottom-left area of the phone.

Step 7: Remove the Broken Charging Port Board

After removing the speaker buzzer, remove the broken charging port board.

Disconnect the antenna head and then take out the charging port board.

Step 8: Install the New Charging Port Board

Place the new charging port board into the phone body.

Secure the antenna head to the new charging port board.

Make sure the board is properly positioned before continuing with the reassembly.

Step 9: Reinstall the Speaker Buzzer and Main Ribbon Flex

Place and secure the speaker buzzer back into position.

Next, reinstall the main ribbon flex and secure it in place.

Step 10: Reconnect the Fingerprint and Battery Connections

Reconnect the fingerprint flex cable.

Then reconnect the battery plug.

Once the connections are restored, place the midframe back into position.

Step 11: Secure the Midframe

Secure the midframe using the 13 screws removed earlier.

Once the midframe is secured, reinstall the SIM tray.

Step 12: Reinstall the Back Cover

Before installing the main back cover, check that there is enough adhesive remaining to secure it properly.

If additional adhesive is required, use B7000 glue or new double-sided back cover adhesive.

Carefully position the rear cover back onto the phone body.

Step 13: Secure the Rear Cover

Finally, use bonding clips to tighten and hold the rear cover against the phone body.

If bonding clips are not available, rubber bands can be used instead.

Leave them in place for some time to allow the adhesive to bond.

The charging port board replacement is now complete.
