LG LS660 Tribute OK, so I tried to install CM 12.1 after rooting and TWRP but got stuck into a bootloop, I think because I didn't unlock bootloader? So I tried to restore with my backup, but TWRP didn't list it as an option even though I selected SD and had the SD with backup files in it. So, wiped the phone completely, flashed an unsigned copy of stock firmware, and after a bunch of attempts got it to flash the firmware, booted up signed into google, restored contacts, made a call, everything was good, until it gave me the option to update, unfortunately I did, and something went wrong, so anyway, I wiped everyhthing again (no OS) and attempted to flash stock firmware like before, but when I go to reboot, it asks me to install SU, if I hit the button to decline it does nothing at all, if I swipe to install, it reboots and only boots back into TWRP, so I wiped everything again, flashed unsigned stock firmware (I do still have original backup folder, but cant figure out how to get TWRP to see it) I installed a new SU zip, reboot, it still boots only to TWRP and wont let me opt out of installing SU. So I'm stuck here, any help would be greatly appreciated thanks!!!
