Did you buy used or brand new? Have you tried connecting it to a pc and update through Kies?

Are you using it for the same network that you bought it for? Maybe post some screenshot on your "about device" section. Also what US network is it branded for and are you using with a SIM for that network now. More info would be helpful.
