Guess what? Today i was forced to reset my iPod totally! Not a thing was left, but i had my library left so the best songs got syncorisized again. But if you have a problem like this:

*Ipod doesn't start
*The screens just black
*It doesn't get in contact with the computer
*Or iTunes
*It just locked itself i didn't do anything!

You can do following things to see if you can get it working again:

*May sound crazy but, try to drop it in the floor from 1dm high, it may get somekind of contact.
*Do not try to do something with the ipod except with iTunes (like try to get it working by using the "computer")
*Press menu and middle button for awhile
*If it starts use iTunes to reset it and upload all tunes again.

If this doesn't work contact reparation service.
