[Sprint HTC One (M9)] nkk71:
Unless it's a hardware problem (could be but not sure since your first post of the problem doesn't provide enough detail/logs), we do need the full output of the ruu flash, in case you used the .exe then you can check C:\RUU_LOG\ folder for the logs, otherwise use htc_fastboot v3.0.9.2, the output would be something like this (this is only an example so don't compare), but we need to see all of it

And since it's not really related to the ROM, you could open your own thread in Q&A, mention us, and we'll try to help.

A simple question though: when you did "fastboot oem lock" did your bootloader become locked?

(doesn't really matter since you are s-off, but I'd like to know if bootloader now says RELOCKED or does it still say UNLOCKED, in the latter case you probably have a hardware problem)
