Good luck ...
I put these question because when i preveusly installed B506 STOCK and afterwards TWRP 18.104.22.168 before reboot i was asked if i want to root my devices and it worked with no problem.
After this i installed the ART fix. Because it was bugee i installed a fresh stock B506 and then instaled TWRP. This time root did not worked anymore. This is my bewilderment.
I read about your B506 root rom but i am tired to factory reset again and install all from scratch.
Thank you again and i'm hopping that you don't leave us in in the near future.
