[Q] LQ Optimus G not booting
Here is the series of events. Upgraded to LG optimus G one week ago and that same day, rooted it and installed Cyanogen 10.1. Week goes by functioning completely normal. Today, the battery was down to 5%. Powered off the phone and hooked it to my PC via micro USB cable. Return an hour later to turn it back on. LQ logo appears for a split second then the screen goes dark though still active because of the backlight. Only response I get is when holding down the power button until the screen goes off. It then powers back up and briefly shows the LG logo and the screen is blank again. No response from any other attempt to boot the phone into recovery mode or normal.
Simultaneous power and volume down does not enter recovery mode, nor does any other combination of keys
