Is it possible to flash new ROM in TWRP recovery from internal storage without using PC. I moved new ROM to my phone and i can see it in TWRP but is it safe to install it like that? Should i move new ROM in some specific folder first or not?
Flashing a ROM from within the recovery is the typical way of flashing a new ROM, you are good to go. Just make a back up first, wipe all, flash ROM and gapps if needed
