Hi, I have an 8GB iPod Touch 2G MC model, and I wanted to downgrade it. Strangely, my iPod came with 3.1.3, but TinyUmbrella found 3.1.2 SHSH blobs for my device on Cydia... strange? So I tried to downgrade. I start TSS server, I put my device in DFU, and when the progress bar appears (yay I was so happy) iTunes throws error 28 at me. I also tried downgrading in recovery mode, and normal mode. Oh, but for some reason, I can restore to 4.0 with the SHSH blobs I saved, no problem. Any reason for this?
