I just rooted my lg motion and went fine, then i rebooted the phone after setting phone up and its stuck on a black screen. i can't access download mode or hard reset mode. Its acting as if the battery is dead. I did make sure through out the process the battery was atleast 75% so its not a power issue. When i hook it up to computer i get the lil beep from pc acknowleging a device but nothing on lg motion screen and the lg support tool and other root scripts say they can't find device. HELP Please!
