I can't up date my iPod touch 5th gen from iOS 6.1.2 to iOS 9.1.2

Try:

- Reset the iOS device. Nothing will be lost

Reset iOS device: Hold down the On/Off button and the Home button at the same time for at

least ten seconds, until the Apple logo appears

- Power off and then back on your router and modem

- Try when connected to another network

- Last, connect to iTunes and update via iTunes.

Note:

If you updatefrom iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.

You can redownload most iTunes purchases by:

Downloading past purchases from the App Store, iBookstore, and iTunes Store
