Sorry for misunderstood, i used LGflashtool and flashed .tot, i can root, install TWRP, the problem is when i try to install a custom rom via TWRP, when i try to flash any rom i got this> E: unable to mount 'system' at the end of flashing. So in the MOUNT option the system partition is unchecked and dont let me check it, ive had never had this problem before. I was able to flash without problem, but now i cant.
