I don't have a working ROM on my Sprint HTC One. I made an error when flashing; I'm on hboot 1.55 and Android v4.3, S-On
You need to do a factory reset and wipe the Dalvik Cache. What bootloader are you using? TWRP or Clockwork would be examples. I would enter this as a comment but lack the necessary reputation.
