I had just sent a text on my Motorola after unplugging it from the charger in the morning, left it for half an hour, and when I came back, it wouldn't turn on. Did the hard reset button combo, nothing. Physically disconnected the battery, nothing. Plugged it into the usual charger I charge it with (from a Galaxy Nexus) and nothing but a solid green light. Plugged it into a higher current charger (from a Blackberry Playbook), green light flashes and it turns on, but only to the Motorola logo.
It only seems to either go into the Motorola logo, the boot selection screen, or AP Fastboot. Nothing else. Unplugging the charger once on will kill it, so looks like it isn't getting anything from the battery. And also, once on, it hard resets itself after about 20 seconds. It just shuts off, then green light flashes, turns on, runs for about 20 seconds, then repeats.
I hear a new battery fixes it, but I had already put a new screen on this thing, a new LCD, a new back, and unlocked it, I'm really not inclined to replace another part in it. Does anybody have an idea of what's going on or what I could do?
