I was recently given an international GSM Galaxy Nexus. It doesn't respond to anything. He tells me that he had it plugged in overnight, and when he woke up, it was dead. I've seen other people who have had this problem solving it with plugging it into a computer, flashing omap, et al. but, none of these work on this phone. No computer even detects that it is plugged in. There is no LED when it's plugged into a wall outlet. Does anyone have any ideas?
