Question [Q] Lost OS - Soft Brick

Hey guys, Nate here.

Problem: My Sprint HTC One will no longer boot up all the way. It gets stuck on the HTC Powered By Android screen. I still have access to the bootloader and have tried a bunch of things but now I'm at the end.

Long story short, I was attempting to root my phone so I could use the tether feature to save $50 on a wifi receiver for the pc. But that didn't go well. In the process of flashing the ROM the phone wouldn't boot anymore. Started doing some looking around found this thread. I flashed the full firmware ruu(successfully) and attempted to use the Sprint HTC One | 5.03.651.3 RUU to install the stock OS again. However when I run the ARUWizard and go through the steps, it freezes at (1/6 Sending). I don't receive any errors at all, it just freezes. I am pretty tech smart when it comes to computer software, but don't know much about Android, obviously.

At this point I just want to get my phone back to normal since rooting is over my head. But I don't want to take it a repair shop and spend money that I don't have if it's not 100% necessary. So any advice would be happily welcome.
