I was running JellyBean when my camera wouldn't respond. I tried to factory reset and re-install JellyBean. I think it installed too fast to be proper, it took maybe 45 seconds then rebooted.
Now it's stuck on a "x" screen but when I boot it into bootloader the screen goes black. Each time I hit the volume key it flashes on to where I can see the options, then goes back to black. If you try to select an option it vibrates times and locks up on a black screen.
Any ideas? It's an HTC Desire HD.
