Here is my story. I've been at this for three hours including searching XDA and other sites. Can't get any options to work.
I was trying to gain S-OFF. I installed a custom recovery (TWRP) and in doing so I could not see any files to flash the new rom... I tried flash CWM, it ended up booting to the CWM text at the bottom left with the version number, and then booting to the plain white (with htc one logo) screen and sitting there and not booting into anything else. Just sits there. Every recovery I flash through fastboot (which is my ONLY option into the phone it seems) does not boot up, the device just restarts to that annoying HTC logo screen.
I was able to get ONE recovery of twrp working and it boots up into it and displays all the options, HOWEVER, it cannot mount... Nothing will mount via twrp.
What can I do?
