Would like some help with s-offing my m7.

So a few days ago, i received an HTC One M7 from my dad. Having rooted and played around with other devices before, I immediately looked up all the guides and necessities to get this thing up and running. It was running Lollipop when i got it, so that means its running HBOOT 1.61.0000. After digging around some more, I learned that It isnt possible to s-off with this version of bootloader. And to go around this, I have to downgrade with a RUU. Now here's my real problem, I cant find a RUU compatible with my CID. I'll paste what i got from the fastboot getvar all command below and any help would be great.
Currently, I am unlocked and rooted. I will be using the stock lollipop rom again.
