The solder connections onto the USB connector have showed up as a problem in more than one phone that I havehad (Original plus two replacements). The pre-heat on the earth connections wasn't good enough and the connectins fail killing the fine connections underneath with flexing of charging cable.

I have managed to salvage one phone with fine soldering but the other one I killed with heat before I got it right.

Symptoms are charge will blink on then off. Bootloader won't connect, eg remains in serial even with cable plugged in.
