    • Using the same bit, remove the two 3 mm screws from the circuit board.

    • Desolder the four joints holding the USB-C charging port there.

    • Pull the charging port off.

    For the love of all that is holy do NOT pull the charging port off. I don't have a set of these to correct the image myself but you also have to desolder the pads from the top side otherwise you risk ruining the entire pcb. Someone with a pair to take pics please correct this.

    Devnol -

    • Solder the new charging port onto the board.

Conclusion

To reassemble your device, follow these instructions in reverse order.
