Step-by-Step Charging Port Replacement Guide
Step 1. Preparing the Device
Before starting, make sure you have all the necessary tools, which you can find in the description. Power off the phone and remove the SIM tray.
Step 2. Opening the Back Cover
Heat gently around the edges of the back cover until the adhesive softens. Use a suction cup to lift the cover slightly and insert a plastic card to carefully cut through the adhesive around the frame. Work slowly to prevent cracking the back glass.
Step 3. Removing the Mainboard Protector Frame
Unscrew and lift the mainboard protective frame by removing 11 screws. Use a plastic pry tool to carefully lift the cover and set it aside. Disconnect the battery plug to ensure safety.
Step 4. Removing the Battery
Release the adhesive securing the battery and lift it out using the pull tab. Handle the battery carefully to avoid bending or puncturing it.
Step 5. Removing the Charger Port & LCD Flex Cables
Remove the bottom plastic protective cover by undoing seven screws. On top of the charging port, remove two screws and disconnect the antenna board and Touch ID plugs. Disconnect the main flex plug and two antennas.
Next, remove the SIM card board and disconnect the LCD connector. Move the battery protector tape aside and carefully remove the charger port flex cable and LCD flex cable. Apply a little heat if the adhesive is too strong.
- Left-hand side cable → Charging port flex
- Right-hand side cable → LCD flex
- Middle cable → Main flex
Step 6. Installing the New Flex Cables
Place the replacement cables in their original positions. Start by connecting the charging port flex cable to the logic board, then attach the LCD flex cable at both top and bottom ends. Reposition the adhesive protector and reconnect the battery.
Step 7. Reassembling the Device
Reinstall the SIM card board and secure two screws at the top of the charging port. Reinsert the SIM tray. Plug in the Touch ID and antenna board connectors, along with the two antennas.
Place the plastic protective cover back and secure all seven screws. Connect the battery to the logic board and reinstall the mainboard cover with all screws.
Step 8. Closing the Device
Check if the back cover has enough adhesive. If not, apply B7000 glue or a new double-sided adhesive. Align the cover carefully, press firmly, and use binding clips or rubber bands to secure the back cover until the adhesive sets.
