When I start my Metro PCS L70 it starts up to LG logo and stays there. If I try to reset it, power and volume buttons, I click yes to erase and reset, twice. It goes to android screen says 'erasing' and then quickly flashes to the next screen (barely long enough to read the word 'installing...') and then just goes immediately back to the LG screen and stays. The only thing the phone allows me to do is go to download mode (volume up, plug into PC) which brings me to "Update Firmware" screen and stays at 0%. Can anybody tell me what wrong with it and how I could possibly fix it? I don't believe the phone was rooted, this is how I received the phone
