I own a LG G2 D805 and I tried do install a D802 ROM. When it booted, the screen showed a lot of glitches, as though the lcd had been damaged. I went back to the recovery and tried to flash other ROMs without success. I got into download mode to go back to stock but now I can't flash any d805 kdz, only d802 kdz, and as I do, the device keeps rebooting as soon as I get into the set up screen or shortly after that. What can I do?
