[Q] Stuck in a bootloop topic

Hi everyone,

I have my AT&T HTC One that's stuck in a bootloop due to me flashing a ROM (ARHD). I did not notice I still had S-On (S-Off is needed to flash the ROM) and now stuck in a loop. I can access recovery (TWRP 2.6.3.3) but sideload just stays at the message that's says its starting.
Bootloader is also accessible, I have all my adb files and fastboot files. I just want to get back to stock 4.3 or 4.4.2, or even a custom rom if it'll work.

Here are my vars:
(bootloader) version: 0.5
(bootloader) version-bootloader: 1.56.0000
(bootloader) version-baseband: 4T.24.3218.09
