[Q] M7 unable to boot/recovery with persistent green LED
I have HTC One - rooted, S-Off with custom recovery. Yesterday I switched from Android Revolution HD into CyanogenMod11 and left the phone plugged into wall charger. Now I just cannot boot into the system, nor into recovery. Phone plugged or not, the green LED is constantly on and I cannot force reboot via PC. The device cannot be found. Any ideas? I don't want to use warranty in it's current shape, before reverting it to original state, but I'm cclearly unable to. Help much appreciated.
