Hi! My iPod touch 3G started acting weird. When it was locked and I pressed home button to unlock it, music playback started instantly. Microphone and volume controls on headphones wouldn't work. If I press the home button twice, iPod does not bring up music controls, but goes to main screen. After all this I decided I will restore it with iTunes and see what happens. I did the procedure for unjailbreaking iPod(hold power and home button, hold shift when pressing restore in iTunes). I selected the firmware 3.1.3, which I'm 100% sure it was the original firmware. iTunes first says extracting software, then verifying iPod restore with Apple. Then displays error message: "The iPod "iPod" could not be restored. This device isn't eligible for the requested build. iPod was jailbreaked. What can I do? Did I do something wrong with the restore?
