(SOLVED) M7 UL won't root, Unable to mount /Data /Cache

Hey guys,

My HTC One M7 UL (PN07120) is driving me nuts. I was trying to obtain root so I proceeded to unlock it through htcdev and did it sucessfully. My phone can boot normally. However I cannot root it. I checked to see whether it had damaged partition tables and got no errors after using the mkfs.ext4 solution. I tried installing several RUUs but when they don't failed with the "incorrect RUU" error, they just don't go past the "getting header 1/5)" step of the process.
I have explored several threads with issues that might look like mine, but they end up not being. I will post my getvar info and the names of the RUUs I've been using hoping to find someone kind enough to give me a hand.

Code:

It just doesn't root because the files (su.zip or superuser.zip) are not to be found anywhere thanks to my inability to write /data. I am going to try @bored_stupid approach and see what it does.

EDIT:
I had flashed this recovery before with success. The problem is it says "Unable to mount /Cache" or "/data" whenever I try to either backup or install a rom respectively. It does offer to install Su.zip when exit, but it fails to do it because when I check it with root requiring apps, o root checkers, they all say the same: No Root.

EDIT #2:
I was able to install a custom rom!!!!!! All problems got fixed after @bored_stupid approach. Thank you very very much. However, before trying the custom rom I did try to install su.zip when exiting TWRP and, differently to the other tries, it did partially write (confirming that /data was finally writable.) I couldn't, thou, install the Binary when phone booted. I will be trying some other roms and have some fun with the device.

One again. Thanks a lot!!!
