When you ran the ruu you would lose recovery. So once returned to gb you had no cmw unless you flashed it. You are not dead I do not think, I just don't know the fix. Someone like globatron may be able to help you
There is a different cmw for gb and hc

Try the one for the view from this thread
Get into fastboot, then place the recovery in the same directory on your PC as the fastboot command.
Fastboot flash recovery "name of file.zip"

You use this like adb. Place it in any folder you want, open a command terminal on your PC, change directories to the folder you placed it in, make sure the recovery is in the same folder, execute command by typing it in the command terminal

Taking a stab at it but your hboot is not unlocked. It would say it at the top of the hboot screen. Maybe you can try to unlock it but I am not sure that will work without debugging
