i bought the phone off craigslist and was working fine for a week. it came with an extended battery and 2 slim batterys. last night i switched from the the masive extended battery to a slim one so it didnt feel like i was holding a brick to my head and if it could go threw a day at work/school. it worked for 20 minutes and then turned off. i pulled the battery, tryed to turn on and the red light came on for a second then off. i have tryed vol down+ power, pluged in, differnt batterys.
help?
