Just bought a LG optimus e900 off ebay, the previous owner said it worked mint, he erased his info and sent the phone to me, the phone will not pass the Load screen now, the LG sign. tried rebooting and emergency download still nothing, i had left the battery out for about 40 min and when i put it in, it loaded for like 20 seconds then switched back the the LG sign, and no more has it loaded again.
