Question S-OFF Hoot 1.44 issues

I have a Sprint HTC One running Viperone 5.8.0 and I can't seem to get S-OFF to work.

It is on HBoot 1.44 and I get an error when running Revone. It is my understanding that only Revone will work with the older HBoot. Do I need to put an old room on first? I'm rooted obviously.

Any advice is appreciated.
