1 - I have installed the latest version of TWRP for the Rezound, and it appears to work fine. Even now. I can even Mount the SD card and transfer stuff to it from the PC.
2 - Any ROM I install from TWRP leads to a black screen on reboot. I see the HTC logo, and then it just goes black. It will then do nothing until I do a battery pull. No matter what buttons I press.
3 - This is not my primary phone and even if I bricked it, it's not a huge loss. Mostly I use it to experiment on so I don't hose my real phones. But I would still like to get it working in case a friend on Verizon ever needs a backup.
I have attempted to install Liquid Smooth ROM and OmniROM with the same result. I had a JB Liquid Smooth ROM on there before and it was working ok. The ones I tried to install were KitKat ROMs.
Any ideas? It is possible I might have accidentally deleted something I shouldn't (wiping caches from within TWRP), but I can't really think of what that would be. When I have installed these ROMs from TWRP it does tell me it was successful.
