I have an old iPod nano 8 and I accidentally upgraded it through restore to factory setting. Now the iPod reacts so slow and it's completely unusable. Any method to downgrade it?
Sorry, but Apple does not provide a downgrade path for the iOS.
Best of luck,

If you "upgraded" it using the Update command, try doing a Restore. Even if you did use Restore, try doing it again. This erases the iPod, reinstalls its software, and sets it to default settings. Your iPod nano is a simple media player device, and should work fine with the latest version of its software.
