Hey guys i upgraded my 3.1.2 firmware to 4.1. Then jailbroke the 3g. I need to downgrade back to 3.1.2(i want to eventually run 3.1.3) I downloaded 3.1.3 firmware. And went to restore, to it. I got an error in itunes(1550). I Never saved any shshblobs, and am not sure weather they were saved automatically. Whats is the best approach for my situation? should i be able to downgrade to what ever the original firmware to the phone was? Am i doomed to ios4.1?
