My phone is stuck on the "Dual Core" screen. It will not turn on or off. I've tried rebooting, had no luck. Was able to get to a FastBoot screen, but only tells me my phone is locked, then goes back to the "Dual Core" screen again.
I was using it and it froze for a few minutes so I held power and volume down to restart it.
If I reset it, it gets stuck there again. I have removed and reinstalled sim card. Tried it hooked up to a charger as well.
