    “device gets into the boot loop sequence or say gets stuck in the welcome screen, just re insert the battery”????

    >>Just Wondering how could this be possible since LG Optimus G is designed as Sealed or Internal Battery package? unless you say break it or dismantle the whole unit to remove the batt.
