I tried updating my iPhone 4 to the 4.2.1 jailbreak last night. I had never tried saving my SHSH blobs before, but I was reading about how important it was, so I saved it with TinyUmbrella (it says on TU that it is the 4.2.1 FW, but I think that is not correct). Anyways I then tried to Jailbreak using the instructions on iClarified. When I tried to restore my iPhone it wouldn't finish, it just gave me an Error message 1013. I tried to go back and restore using TU, but I can't and now my iphone is a blank brick. Did I completely destroy my phone or is there something I can do?
PS I am pretty much a technical dunce, so if you can dumb down your responses, I would appreciate it a ton!
