    Default Downgrading iphone4 4.01 8B117
    So my jailbreak just broke. All cydia packages still existed but didnt load? So i restored and to no supprise it upgraded to latest version which was 4.01 bootrom 8B711. So my question is how do i downgrade without my SSH blobs? Ive tried sauriks server but it just keeps bringing up an error? Can i jailbreak 8B117 4.01 with other methods than jailbreakme. Any ideas

    Cheers

    If you hit restore, you must now be at 4.1 correct, not 4.0.1

    Did you jailbreak at 4.0.1 and save your shsh blogs.

    Agreed, and 4.1 is not jailbreakable on 4.1 and as 4.1 updates baseband you may never be able to unlock...

    Not if you have 4.0.1 shsh blogs, have you checked with Cydia yet.

    Are you from New Zealand ? Recently an Earthquake there.

    Yes, you can also save your shsh blogs with Cydia and stored it locally even though you are not jailbroken.
    Download tiny umbrella.
    Run Tiny Umbrella
    Plug your iphone 4
    It will recognize it
    Click Advanced Tab
    Device /Version : select iph 4 4.0.1 shsh blogs
    Request : Cydia
    Click Save shsh
    Wait for answer
    Click Display shsh to see
    Do this on 4.0, 4.0.1 and 4.1
    Goodluck, if you have 4.0 or 4.0.1 , PM me I can help you downgrade.

    There is no jb for 4.1.

    Depends on what model iPod Touch you have and if you have your SHSHs (if applicable) to downgrade first.

    I may have to go to bed now.

    If your answer is Yes then
    With the Device /version still at ipod 4.0.1 shsh
    Put your ipod into DFU mode
    Start Tiny Server
    Do the shift + Restore to 4.0.1 ipsw
    Let it restore.
    If at the end of the restore , you get an error, try using
    kick out of recovery from Tiny Umbrella. If no error, then you are good to go.
    Good luck.

    If the Answer is NO, then you have to wait for a new jailbreak.

    This says you have saved your 4.1 SHSHs. You'll want to select 4.0.1 like Yeow said in advanced options. The log you just posted is for 4.1, you'll want to pull for 4.0.1.

    It's not the same, it's device specific. You'll need SHSHs for your device.

    What iPod do you have? If it's a 3G you can't use a 2G SHSH.
