How Can You Fix An Ipod Nano?

Press middle button and menu button at the same time that will reset your ipod and keep everything on it the same.  Ex. Same songs, pictures, and videos.

Unfortunately unless you are good a at home repairs you probably won't have much luck.  If you are take the nano apart and carefully insert a small Phillips screwdriver into charger hole and re-round essentially and then put back together be carefull you could damage the circuit board if it isn't already.  I'm not sure where you are from but if you take it to a electronics repair shop they probably can fix it for you.  Just tell them you don't care what it looks like you just want to be able to charge it again as cheap as possible otherwise it will more than likely cost more than what the nano is worth.
