When I get "fastboot getvar all" I see that my "version-main" is 3.23.666.1 (is that the right one to look at?) and so I've scoured for hours for an RUU but only found OTAs which I don't know how to use. If it helps I'm on HBOOT 1.55.
I also remember pressing unroot in OTA unroot (I don't remember the exact app name) and tried pressing restore root but it did nothing so I started doing the above stuff with RUUs.
I'm pretty stumped right now and I would appreciate any help at all, thank you!
If you have an unlocktoken flash it with fastboot flashunlocktoken Unlock_code.bin
If you dont have it, go to htcdev.com and visit unlock bootloader section and follow instructions there.
Once your bootloader is unlocked again, flash twrp recovery and ABD sideload some ROM.
After this you can start all over again whatever it is you were trying to do.
P.S. this will not get you the right RUU package but it will get your phone back to useful condition.
My advice is first you find an RUU for your phone and then do the bootloader manipulations.
