How to Select the Best Tools for the Repair

Step-by-Step Charging Port Replacement Process

Step 1 – Remove SIM Tray

First, take out the SIM tray using a SIM ejector tool.

Step 2 – Heat the Back Cover

Gently heat around the edges of the back cover until the adhesive becomes soft.
We are using a heating pad. Place the phone with the back cover side down on the heating pad and select the Mobile Phone Heating option.
Alternatively, you can use a heat gun or hairdryer.

Step 3 – Open the Back Cover

After heating, use a suction cup to create a small gap between the frame and rear cover.
Insert a plastic card pry tool and slowly cut through the adhesive around the back cover. Carefully lift and remove the back cover.

Step 4 – Remove Wireless Charging Pad & Disconnect Battery

Disconnect the wireless charging pad connector and gently lift it out.
Then disconnect the battery connector to ensure safety while working on internal components.

Step 5 – Remove Speaker Cover

At the bottom of the phone, remove the speaker cover by unscrewing five screws using a Phillips screwdriver.

Step 6 – Disconnect Ribbon Flex Cables

Disconnect the two main ribbon flex cables connected to the secondary board to access the charging port board.

Step 7 – Remove the Broken Charging Port Board

Unscrew three screws securing the charging port board.
Use a plastic pry tool or tweezers to lift out the broken charging port board carefully.

Step 8 – Install the New Charging Port Board

Place the new charging port board into position.
Secure it with three screws and reconnect the two ribbon flex cables.

Step 9 – Reinstall the Speaker Cover

Place the speaker cover back and secure it using the five screws removed earlier.

Step 10 – Reconnect Wireless Pad, Battery, and SIM Tray

Reconnect the wireless charging pad and the battery connector.
Insert the SIM tray back into the phone.

Step 11 – Seal the Back Cover

Before closing the phone, make sure the back cover has enough adhesive.
If the old glue is weak, apply B7000 glue or use new double-sided back cover adhesive.
Press the back cover firmly into place.

Step 12 – Tighten the Back Cover

We are using screen binding clips to hold the back cover tightly.
Alternatively, you can use rubber bands and leave them for some time to ensure proper adhesion.
