I am having the same issue. It had been shutting down randomly. None of my apps would work or cause it to crash so I decided to reset it and wipe everything. Now it is stuck on that annoying robot erasing but the progress bar has not moved. I have tried shutting it down, holding down power and volume and it just reboots back to the same damn screen. I am throwing it against the wall and Android can suck it! Apparently I purchased a POS.
