Thread: Updating iPhone 4 from 4.0.1 to 4.3.3 or 4.2.1

    Default Updating iPhone 4 from 4.0.1 to 4.3.3 or 4.2.1
    I was wondering how can I update my firmware without having to go to 4.3.5. I am ok with 4.1 or 4.2.1 or 4.3.3 with or without baseband preservation. It really doesn't make a difference to me since I have a gevey chip I can use. Any help will be greatly appreciated.

    Did you use Tiny Umbrella to check which SHSH blobs are available?

    SHSH blobs are required to restore any non-current iOS.
    Download and run Tiny Umbrella (link below, post #1), advanced tab,
    ... check 'set Hosts to Cydia', Save SHSH, give it a min to finish;
    ... uncheck 'set Hosts to Cydia', Save SHSH, give it a min to finish.
    ... In the General tab, what SHSH blobs are displayed?

    While you're waiting, re-read the Tiny Umbrella post #1 for valuable info.

    Here is the strange thing I already did like you asked me to do and it only shows shsh blobs for 4.3.5 and this iphone has never had 4.3.5 installed on it. Since it is on 4.0.1 and jailbroken, shouldnt it have SHSH blobs saved for that specific f/w version?

    No. SHSH blobs are available only when they are current. When Apple releases a new version, it stops signing the old one.

    Using iFaith, you can create a 'pre-signed' firmware (doesn't need blobs from Apple) from you current running iOS 4.0.1
    You don't need to restore with it ... just create it and keep it in a safe place for emergencies.
    I would strongly suggest doing this. At least you will have one restore option besides 4.3.5

    Additional information:
    Open Cydia. At the top there ...may... be a line starting with "SHSH: iOS " in green.
    If numbers are show after, these are blobs Cydia ...may... have saved for you automatically.
    The results from both TU and Cydia should match
