Q: But I Have to Enter A Passcode (the Resrictions passcode) But I dont know it. What Can i Do?

Restore your Touch as a new device on your computer.

Is this referring to a previous question?

It starts with But i have to enter the restrictions passcode.

If this isn't referring to an old question and you don't know the restrictions passcode,

You will need to restore your iPod to factory settings.

As long as the music has been purchased from the iTunes store, than yes.

Custom songs that you may have put on your iPod on your own through iTunes will not download from iCloud.

You will have to put those back on manually yourself.

Forgotten RESTRICTIONS Passcode

- Restore from a backup that was make before you added the Restrictions passcode. If you restore from a backup made with the Restrictions passcode the Restrictions passcode is also restored.

- Restore to factory settings/new iPod.

- If you are up to file manipulation see:
