⚙️ Step-by-Step Replacement Process
1. Power Off the Device
-
Shut down the mobile phone completely to avoid electrical damage.
2. Disassemble the Device
-
Use a heat gun if the back is glued (60–80°C).
-
Remove back cover and screws.
-
Disconnect the battery first (always!) to prevent short circuits.
3. Access the Charging Port
-
Remove the loudspeaker module or charging board shield if present.
-
Disconnect any flex cables and antennas around the charging port.
4. Remove the Faulty Connector
-
If it’s a board-mounted port:
-
Use a soldering iron or hot air rework station to heat the solder points.
-
Carefully remove the charging port using tweezers.
-
Clean the solder pads with flux and desoldering wick.
-
5. Install the New Connector
-
Align the new charging port on the board.
-
Use flux and solder to fix the port in place.
-
Ensure strong connections on all pins without solder bridges.
6. Reassemble and Test
-
Reconnect the battery.
-
Power on and test charging with an original cable and adapter.
-
Check port firmness and data transfer if supported.
-
Once confirmed, close and screw the device back properly.
🛡️ Pro Tips
-
Avoid applying too much heat—can damage surrounding ICs.
-
Always use ESD protection.
-
Check for other damage (e.g., liquid, burnt traces) before replacement.
