I am in a bit of a predicament. When I tried power-off my phone from the TWRP reset menu TWRP froze up. I could click any of the buttons on screen (the clicking/tapping animation did go off) but got no repsonse. When I tried to do a forced power-off by holding the power button, the only thing that happened was the screen locked. Now I am stuck on the lock screen because for some reason the phone won't unlock when I slide to unlock it. Am I screwed and will have to wait until the battery goes dead to be able to get back to the bootloader? I tried to flash TWRP 2.8.6.0 inside TWRP but it flashed to the boot partition instead. I have a backup but I need to first be able to flash the new recovery to restore it.
