Hello everyone. I have a problem and I need some of that friendly XDA assistance.
I have been using the AT&T LGOG for about a year now, and have it rooted, unlocked, and flashed CyanogenMod.
I left my phone to charge, plugged into the outlet. When I unplugged it, the screen failed to turn on, remaining black, but the soft keys lit up. I pressed the power button, but no response. Then the soft keys back light went out. The phone, I guess, just shut off. So, I tried turning it on. Instead of the usual Google bootloader logo, the screen remains black. I hold the power button, and nothing happens.
So I plugged it in, and tried turning it on again. The red notification light on the power button illuminates solidly for a couple seconds, then steadily flashes. I have encountered this before, so I know I have no battery and leave it to charge. After an overnight charge, however, I try turning it on again, but am greeted by the same red flashes.
I've tried charging it with different chargers, cables, plugging it into the computer, using different usb computer ports, all with no change in results. When plugged into my computer, it shows up as unknown device, but when i try turning it on, as the notification light flashes, it changes from unknown device to hid compliant device in device manager, but back to unknown device if i let go. I have tried putting it in download mode, but the screen does not show a trace of life. LGNPST fails to detect the device.
I have searched and found in other threads similar occurences. I suspect the battery is at fault here. But before I do a battery pull, I want to make sure I have tried everything else. I cannot RMA it as it is out of warranty, has a large crack on the back, and has a custom rom.
Assistance is requested and appreciated!
