Hi I bought this T-Mobile Vivacity a few months ago , and it was all perfect, until today, when I dropped it. Now it won't start if it is not plugged in, and plugged in it starts just normally, loading Android , and just reboots itself after a few seconds in loading. I've installed a new ROM a few days ago. Maybe they are all related. Any ideeas? (sorry for my bad english, I'm not a native)
