so i tried to download the img and it says cannot mount, disc error. i deleted and tried to download again and windows says keep or discard? no matter what i select it will not download the file again. once again i tried to look up why it can't mount this file/corrupt and nobody seems to have a straight answer.You're doing it wrong. You need to boot into fastboot, then from there u boot into twrp (fastboot boot twrp.img). Then flash twrp.zip from the recovery you booted.
tried on internet explorer and when i press enter on powershell "the disc file is corrupted"
