I recommend testing the USB C flex cable assembly before you reassemble the phone. As soon as it’s connected to the upper connector and the battery is plugged in the phone should be charging. Mine was broken from the factory but I went to a great local repair shop and got a new one, the guy said 1 out of 15 is broken from the factory. Great tutorial, successful repair.
