I was stupid and hit erase all content and settings trying to clean my phone to give to a friend. Now my iphone 4 (ATT 4.2.1) just loops and gets stuck at the greenpoison logo. I tried running ifaith, did the blobs, and tried to build the ipsw, but it always crashes halfway doing that. I then tried to use snowbreeze and build a 4.2.1 to perserve baseband, and whenever I hit restore in itunes, I get a 3194 error. I used to have the shsh blobs from cydia, but my computer crashed, so I was screwed. Is there anyway I can get back to a firmware that is jailbroken and unlockable? I really need some help and thanks.
