Try to take the battery out for 5 minutes. If that doesn't work, than you need to bring it back to you're dealer, otherways you'll have a bricked phone.

I think that you're problem is, that your old software was corrupted, and the phone's hardware got destroyed(in my case too). I flashed it with wrong firmware, and my phone started flashing and then, I turned it off, flashed with generic, and I got reset. Maybe that happened to you too(in some kind, or case), and now, I'm 50% sure that you'll get a new one, when you bring it into service.
