Ipod 4th generation no safari or game center

I just got a 4th generation ipod touch for m son "used" and the safari wont work, just a blank screen and takes me back to the home page. I can get to the apple apps store and down load apps but when I go to play the game it asks for my apple I,d which I enter and then the screen just keeps trying to log me in and doesn't. It also says thee is a update available which fails to install that update is IOS 6.1.6



So no game center and no internet. But can get to ITunes and App store

It says im connected through my wireless



I bought it used and they said they reset it to factory settings, when I tried to reset it, it asks for a passcode which I have no idea what it is.



Any help appreciated as im not to up on ipod and technology in general
