So I have an HTC One (Unlocked, HTC__E11)
It has 4.3 (Standard, with root), S-off.
Yesterday I wanted to restore it back to stock, so I could get the 4.4.2 OTA update, only a problem arrised.
I flashed back stock recovery -> tried updating OTA, got red triangle during update.
RUU gave me errors aswell.
So after some googling, I decided to downgrade the HBOOT to 1.44, but now I have a big problem.
USB won't work anymore in fastboot.
When I try either ADB or fastboot, my phone is just not recognized.
Windows also doesn't recognize the phone and just gives me an error (Both Windows 7 and Windows 8.1).
I suspect it's because of the HBOOT, but there's no way for me to revert it.
What I really want now is just to revert my phone back to stock 4.4.2 with all the updated original recovery, hboot, etc but I have no idea what I must do now as I can't use fastboot or adb.
Thanks in advance.
