I just got this used G1 that i bought on ebay and is locked cuz i dont know the password/username of the person who sold it to me and neither he remembers it. The point is i tried to factory reset the G1 but when i press home+the red button it sends me to a tricolored page i think its called the bootloader i dont know what to do cuz i cant have access to the phone because its locked and i cant do factory reset what can i do??? Thanks
