nrg3x, probably you are doing something wrong here. There is no need for LtnFlash when you update your firmware.
Download firmware (.EXE-file) from Lite-On and apply your "patches".
Patched mine HS0Q this evening with spdhack, readhack and auto-bitsetting.
Works like a charm.
Edit: I see code65536 gave you an answer. This post stands as it.
