i am on CWM and forgot to flash TWRP before upgrading ARHD. Now the phone is in a bootloop and cant enter recovery anymore.
I can enter fastboot mode on the device, it even shows "Fastboot USB", but on windows (8.1) i only get the "device not recognized" message, and in the device manager it says "Unknown USB device (Device failed Enumeration).
I use the original HTC cable on a USB port on the backside of the PC.
I have tried using the google adb drivers, and i tried installing htc sync, both to no avail.
Any ideas how i can get my PC to "enumerate" my phone?
