I'm a relative newbie to custom roms, I've got viperone 6.2.1 running on my HTC One M7, within the last half hr, the screen is completely off and even when i plug the charger in the red led up on the top doesnt light up, it was working fine this morning too and was fully charged. i tried holding PWR & VOL Down button but no luck . Any Ideas how i can reboot the phone?
when i plug the phone into the laptop it tries to install QHUSB_DLOAD drivers and it doesnt install them properly. so i have this listed with an exclamation mark in device manager.
