you have to put in your code
On the main menu of your iPod, select 'Settings'. Then go to 'Playback', then 'Volume Limit'. Then all you have to do is enter your combination and set the volume limit to where you want it. Although, if you can't remember the combination that i going to be a problem. :S
For an iPod Touch, go into setting, then music. Turn volume limit on and select the desired maximum volume. For classic iPod, go into settings, and there's volume limit. I've never had any other type of iPod, but I'd assume it would always be under setting somewhere.
you have to make up a code.
try to give the exact password...
You have probably reached the maximum volume limit on the iPod Touch. You can change the maximum volume settings by going into the iPod Touch settings.
how to unlock a ipod nano 4th generation
Well, use Redsn0w to jailbreak/unlock the iPod.
You have to Restore the iPod through iTunes if you don't have the combo to unlock it.
Go into settings from your home screen. Then click on Music, then Volume Limit. You can change the limit of your volume here. My iPod put a limit on mine once without me knowing, and this is how I fixed it. You might not have the same problem though, and you might try new headphones or contacting Apple if none of those work.
restoring to factory condition that's the way to unlock any iPod
