Did you unlock bootloader with htc utility? What did you use to gain s-off?
What version is your H-BOOT?
Some roms I was flashing checked for 2.10.0000 and rejected anything else, so when I upgraded to 2.10.5555, most of the kit kat rooms took a poop on me.
Not sure if this is still an issue though. I would imagine those errors were caused by the person compiling the Roms, but may have been resolved since.
