right now I have an iphone 3GS (new bootroom) updated to 4.2.1 jailbroken with redsnow this iphone is not activated with itunes and will not restore bc of jailbreak. Pwnage tool does not allow me to restore with 4.2.1 i need to downgrade to an older version with my shsh blobs on cydia. I have read tons of tutorials and tried desperately to figure this out, but I dont know how to retrieve these blobs from Cydia to use in Itunes to restore to one of these older versions. From my understanding, Tiny Umbrella is supposed to be able to read these blobs when my phone is connected. The only modes available on my phone are DFU or using redsn0w to boot tethered. neither of which is recognized by TinyUmbrella. I even manually entered the ECID but it says iphone is unconnected. This is my first time using Tiny Umbrella, so I do not have these blobs directly in the program, but all my old blobs are listed on my Cydia homescreen. *how do I pull these blobs from Cydia to use for restoring in itunes? am I looking for these blobs to be ipsw files? if not, what exactly are these blobs and how do I use them when using (Ctrl + restore) in itunes. I have tried to understand all the tutorials for this process, but I am missing some big clues I guess. everything else makes sense, but nothing I do allows me to see/use these blobs listed on Cydia. I know these questions are extensive, but I am running in circles and would greatly appreciate any insight.
