HTC One M8 Can't restore to 8.1 from 10080
Hi,
After updating to build 10080, I cannot revert to 8.1. I've performed ~5+ hard resets, numerous soft resets. No windows computer (7, 8.1, or 10) will recognize my phone. It charges when plugged in, but is not recognized in device manager nor windows phone recovery or HTC sync manager.
If I put it into recovery mode it will see it in the device manager as Unknown USB Device (Device Descriptor Request Failed) or sometimes (Port Reset Failed). I've tried different USB cables and made sure the HTC sync manager and HTC drivers are installed on the computer.
I've tried USB 3 and USB 2 ports as well to no avail. I have managed to find the HTC Verizon 8.1 original image/ruu file and can't restore it with the HTC tool because the phone won't recognize.
Any suggestions?
