Help - I had my iPod Classic 7th Gen 160gb upgraded to a digital memory by ipodrepairs.co.uk. They recommended Rockbox so I downloaded to system onto the aforementioned iPod. I couldn't get anything to work or load so decided to delete and return to iTunes. Oh dear, it seemed to go well but all I get now is the message shown in the photo.
I'm clearly not smart enough for Rockbox so can someone please tell me how to get back to iTunes?
