I bought a 32 GB iPod Touch 3G (MC), with firmware version 3.13. I immediately jailbroke it. I ran Cydia, pressed the "Yes, make my life easier" thing, and I began downloading. One day I accidentally made my iTouch stuck on a reboot loop, and I had to restore with iOS 4 (being a n00b at the time, I didn't know that I could download older firmware). Since then I have fully erased the iPod Touch and restored it (are the SHSH blobs still there?), while searching for a way to either downgrade it to either 3.13 or 3.12, or jailbreak it directly. I tried to downgrade it the traditional way (Modify HOSTS file, Launch into DFU mode, download 3.13 firmware, Shift-restore and select it), but an 3194 error always comes up. What should I do? Is there a way to jailbreak iOS 4, or is there a solution to my downgrade problem?
