Guys can someone help me? I have a sprint lg g2 that was flashed with a tmobile stock via lg flasher or something and it was then flashed with sprint stock rom on it(that failed)...so, now its on a t-mobile rom but, it reboots every 10-20 secs....I have managed to re-root it again, but having trouble flashing custom recovery on it. also, now it doesn't show up under adb devices anymore...but, I can get it into download mode, can I still save it? or all is lost?
