My LG G Stylo soft bricked

I need help, I unlocked the bootloader in my LG G Stylo (LG ms63120b) and I ran but not installed the recovery, then I select to swipe to install su and now I can't do nothing
I tried to install the stock rom but LG Flash Tool 2014 gives me "Contact administrator" error, I tried LGUP and UpperCut but my phone is not recognized
Now I can't access to the fastboot menu, and when I try to hard reset it the phone just doesn't makes nothing.
EDIT: I downloaded LG UP DLL for LG MS631 and I selected the "refurbish option" and the firmware upgrade loaded 100% and now my phone just stays in a black screen. (Now it is hard bricked)
A "disable-dm-verity & forced-encryption" zip MUST be flashed before anything else (since android LP some oem's, MM 6.0 almost all others) This file is often available anywhere Supersu, et al., is available.
