Hi,

Having A Very Strange Problem Phone Is Locked On Gmail Account Due To Wrong Pattern Attempts.. Things I Tried...

1. To Hard Reset It Phone Is Going To Recovery Mode With Volume Keys But Options In Recovery Mode Is Not Visible Already Tried Approximately All Possible Keys Combinations..

2. Tried Flashing KDZ Files With LG Factory Flasher... But After Flashing Firmware Phone Was Still Stuck At Gmail Account..

3. At last I Erased It And Resurrected It With JTag..
