Stuck in ROM install load screen- Can't get to Bootloader
I posted this in ATT HTC One, but it's not getting any attention.
Unlocked and rooted my phone last night using the latest version of TWRP. I mistakenly (not knowing at the time) used the Cyanogenmod installer kit which gave me an error during install. Now my phone is stuck on that spinning CM loading screen. When I go to get into the bootloader (power + volume down) my phone restarts and goes to the bright HTC screen with the red writing on the bottom, then goes right back to the CM loading screen and not into the bootloader menu like I want.
I have not yet tried the trick of holding the phone near bright lights to try and get it into bootloader. The USB cable I think is fine as well and not a cause of anything.
Any suggestions please? I have searched through this forum a lot, but haven't found this exact problem yet.
