Alternative: Charging Pinout

If you are simply trying to repair the charging port (to charge the battery) and not connect to a PC, you do not need the data pins. You only need to solder a new Micro-USB or USB-C female port to the VBUS and GND legs of the original charging connector block on the bottom of the phone.
