Sorry stepping on this post but I have a Verizon QMV7B tablet that is also stops at the "powered by android" screen sits there for 10 seconds or so then looks like it shuts off and powers back on by itself. none of the buttons appear to functioning. holding the power button down for minutes doesn't do anything it just keeps at this loop. tablet slowly started to battery die until it wouldn't charge so bought new battery and stuck in it and that's when it started this loop. I have tried all the button sequences to try to get it to go into any kind of recovery mode but nothing responds. just the stock rom and nothing was messed with. ideas?
