I decided to go downgrade from iOS 7 to iOS 6. While holding the shift key, I pressed 'Check for updates' on iTunes and it let me select the file. I selected the iOS 6.1.3 IPSW. After updating it was stuck in an recovery loop, no matter when I reset, it returns back to this mode. Back then, I used Redsn0w to apply a recovery fix to this iPod and usually it works. But now, it doesn't! It still goes back to recovery mode. At this point, all I want to do is backup my files and restore. How do I do that?
