Thread: 3gs 4.0.1 downgrade to 3.1.2, no prior files saved

    Question 3gs 4.0.1 downgrade to 3.1.2, no prior files saved
    Ok before I knew how or what I-tunes wanted me to upgrade my 3gs and I did. Now my speed is down and battery life is considerably shorter. I have read all Kinds of stuff and it has left me more confused than when I started.
    Is there a way to get or make a shsh (???) file when none existed before?
    I have found and downloaded 3.1.3 & 3.1.2 IOS. Also USB view & umbrella.
    I want to downgrade iPhone 3GS 4.0.1 to 3.1.2 as nearest I can tell from reading its the most desirable OS.

    If you didnt grab the SHSHs for 3.1.2 or 3.1.3 or even 4.0 before, you cant get them now. There are windows for grabbing them either thru Cydia or TinyUmbrella and if you hadnt done it before, you missed those windows.

    This means you cannot downgrade at this time and can only restore to 4.0.1.
