The italics is also in the previous reply

Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.

If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled

If recovery mode does not work try DFU mode.

To restore from backup see:

Restore your device from an iCloud or iTunes backup - Apple Support

If you restore from iCloud backup the apps will be automatically downloaded. If you restore from 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

If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.

OR

If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone and use Remote Wipeto erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.

You can also wipe the iOS device by installing the FindMyiPhone app on another iOS device and using that app to wipe the device.

Use recovery mode:

Erase your device with recovery mode

If you've never synced with iTunes or set up Find My iPhone in iCloud, you'll need to use recovery mode to restore your device. This will erase the device and its passcode.

1. Connect your iOS device to your computer and open iTunes. If you don't have a computer, borrow one from a friend, or go to an Apple Retail Store or Apple Authorized Service Provider.
2. While your device is connected, force restart it: Press and hold the Sleep/Wake and Home buttons at the same time. Don't let go when you see the Apple logo — keep holding until you see the recovery mode screen.
   
3. When you see the option to Restore or Update, choose Restore.
   
   iTunes will download software for your device. If it takes more than 15 minutes, your device will exit recovery mode and you'll need to repeat steps 2 and 3.
   
4. Wait for the process to finish. Then you can set up and use your device.
