my 6th gen nano stopped working and is not recognized by my computer or in itunes. I tried rebooting with directions, it still doesn't work. I've tried pluggin into power source and pushing the on off button with the volume down button- this doesn't work.

My 6th gen nano ipod stopped working. I figured it was because it was next to my sweaty body, so put it in rice. I sought help from internet and tried all of the troubleshooting steps; i.e pushing down the power button and the volume down button consecutively, plugging it in to a power source, waiting 10 minutes and pushing the buttons while it was plugged in. Nothing has worked thus far. Is there anything else that I can try?
