I've read several threads on several sites on this topic (one would think Motorola would take a hint and fix this). I have a Moto Razr XT912, have had it for well over a year now so warranty is out of the question. Over the last several months, it's been acting very badly. It wouldn't start even after leaving it on the charger (yes the factory supplied one) for several days. I tried all the button sequences I've seen; hold volume down and power on for 10+ seconds... hold all three for 10+ seconds... Hold the power button while standing on my head humming the national anthem, still nothing . Not even a flicker. I noticed that if I plug it in the white light flashes, then flashes again after a couple seconds. I discovered that if I plug it in, sometimes and after several (20-50+) tries at plug and unplugging, about the time the light should flash the second time it will power on or go to the charge screen. Then after a bit and I can power it on. That worked for a while. I even attempted to do the "battery calibration" but once it got down to 15%, powered off, it took FOREVER to get it to charge and restart. Most recently, I got it to go to the charging screen, it said it was charged up to 100%. I tried to power in on and... nothing. Now, I still notice when I plug it in, the white light flashes, twice, but now I can't get it to do anything. I even bought Team Black Hat's little Factory Cable adaptor thingy (Motorola Factory Adapters) and connected that, nothing. By the way, when I connect that the light only flashes once, or not at all. The battery should be good. The phone said it was charged, how can I force it to start? Heck, I even popped the back off and tried to "jump start" it with a spare USB cable I had! By the way, I'd done that before, when it first quit working, and it seemed to help then. I won't be out anything if it's toast, but if I could get it powered up again, at least I could get my info off it so I can sell it for parts or something!!
Any help is appreciated. I'm willing to try anything at this point!
Additional information: I put my multi-meter on the battery and it's charged to 2.75 volts. It SHOULD start, what can I do??
