Hi I went to root my HTC One M8 using the toolkit created. I then installed super su with TWRP and rebooted the device. The device was stuck in the HTC One M8 logo. I went into recovery again and wiped data and cache. Rebooted again but this time after the HTC ONE M8 screen i just get a black screen. I thought I might of deleted the system so I tried to instal Cyogenmod 13 onto it. I flashed the Cyogenmod recovery and booted into the recovery. But everytime I do that I go back to fastboot in bootloader. I cannot get into recovery. Tried to install TWRP again but same thing. I'm super stuck!!! Someone please help?
