Officially Stumped! Please help!

[unadventurer]

Ok I'm a little stuck and I need some help getting my One S up and running again.

I was running a previous version of this rom:
TrickDroid v6.1.0
[ROM][T-MOBILE-US][S4][05JUL] TrickDroid v6.1.0 | Tweaks | Best battery life | Stable - xda-developers

and decided to upgrade to v6.1.0 and install the tweaks package.
I used fastboot to flash TWRP as the install suggested to expedite the process.

TWRP doesn't use the same backup images as CWM (which I now know)

So, once I wiped/flashed the new ROM I got stuck in a boot loop (try to boot once and on the second try it boots back into TWRP)

Also, TWRP will not mount the SD card. I have the proper drivers. Using commands from the PC with fastboot works fine. I also do not have a ROM on the SD card since wiping the phone deleted it. (I'm an idiot)

Is there a way to flash a backup or something with fastboot? Suggestions?
I'm kinda stuck here...

I guess I soft bricked it!

Im currently downloading the RUU for T-Mobile US and using this tutorial...
[How To] Unbrick / Restore your HTC One S back to 100% stock "relocked"

I'm sure I'm not the first to do this but eh.. I'll report back on my results for any other noobs who may stumble across this.
