NO OS INSTALLED, s-on, no root

Hi guys! I tought I had rooted my HTC One m7, so when i was about do to a factory reset to install cyanogenmod's custom rom i accedently wiped everything, including my OS. So for 3 days i've been trying to do almost everything I could do, been reading almost every thread about soft brick htc one on xda with no luck.
Since I have S-ON I cannot flash a RUU compatible to my phone (7.19.401.30 not available for S-ON) , and since it's not rooted I've not managed to get rumrunner so make it S-OFF. I did try to sideload SuperSU to root from recovery (TWRP) , no changes in what i could do with a new ROM. I'm really tired of trying and trying and now about 1hr ago my device won't even show up when I type "adb devices". Does not work with re-installing the drivers, nor does it work with new drivers. And I'm feeling really helpless and I really can't afford a new phone atm...

So my questions are, how could I get my device to show up in adb devices? (It's not recognized by my computer while in HBOOT but fastboot works just fine)
And when/if i get my device to show up, hon can I return to stock/install any ROM to get my HTC going again? :crying:
