Also, OTA depends on your carrier. It may take longer than a computer-based upgrade.
I'm not sure, but I think you misread: "I charge the battery in a wall charger".
If I get it right, he takes the battery out of the phone and charges it separately.
I think more of a USB connector, which is ripped of the PCB.
Maybe it can be resoldered.
but that would be a very uncommon failure for this phone, as the connector is very good soldered:
Maybe it's just a defective Cable?
