I have an Optimus G E970. When I turn it on I have to hold the power button for a couple seconds. It never shows any ATT or LG or google logos on startup. It goes straight to a black lock screen. I have tried for months to get into download mode. recovery mode, emergency mode and fastboot to no avail. If the battery dies it has to charge for a few hours before it will come back on. Even then I have to unplug the charger from the phone, then when I hear the ATT tone I have to plug it back in. Somebody please help.....I just broke the ribbon on my camera pulling the battery out. Which did nothing. If I can get it into download mode I am confident I can flash it back to stock and start over. It is rooted and has freegee installed. The phone when on works fine with no issues. I want to update it though. hhhheelllppp
