I installed the GSAM battery monitor root companion. When it asked me to reboot I pressed reboot. Screen then froze and then went black when I hit the power button. Phone is now dead and unresponsive. No lights when plugged into the charger. Sound does play when phone is connected to the computer, and shows in device manager as Android Phone under Other Devices and HTC One_M8 under Portable Devices, which makes me think I can bring it back, but so far no luck. :crying: Phone is rooted and s-off.
