As time passes and you customize settings on your iPod nano, you may want to reset all settings to "Factory Settings", or the state of your brand new iPod nano, when you received and unpacked it. Resetting all customization is very easy, but fortunately difficult to do by accident. In this tutorial, we'll show you how to quickly restore all your iPod nano's options and preferences. (Note that if you changed your iPod nano language setting by accident, no need to restore the entire iPod: restore the original language of your nano.)
To restore all settings on your iPod nano:
Your iPod nano immediately restore everything to "factory settings", and brings you back to the most important screen, where you will choose the language of your nano. Scroll as needed, and click on the language of your choice. Your iPod brings you back to the Settings screen, displayed in the language chosen, with all options back to their original configuration.
As mentioned in the confirmation message, your iPod nano still retains all your music, audiobooks, playlists, videos, pictures, movies, and other data. The only changes are in the iPod's behavior, which items are visible or hidden from the Main Menu or Music menu, etc.
