You just have to reflash it.
All you do is restart (hold down back and up)
Then, while it is restarting,you need to do a refash (hold down back, left and the select button).
That should be it.
If those are not the right commands, call Microsoft and ask them how to reflash the zune to factory settings. They'll tell you in like 2 minutes.
Don't bother tellingthem everything yo told us, they'll just be stupid and act all dumb.
If that doesnt work, return it and get another.
Your fault you bricked your zune.
