i have a s3 neo i9301l. as my usb port is broken, i installed kingroot and rooted the ohone. then installed twrp 2.7.8.0 via twrp manager and romeved knox via zip intall. now i wanted to flash cm 11/12.1 but im getting install error on twrp. am i missing something? maybe both cm threads links to the twrp version 2.7.5.0 and i installed a newer twrp?
i didnt wiped data befor flashing, as i have no ability to recover the phone if something going wrong after wiping data
