    Downgrade 5.0.1 to 4.3.3 / 4.3.5 - Requirement :

    Before we show you how to downgrade 5.0.1 to 4.3.3 / 4.3.5 or any iOS version please keep in mind that you can only downgrade your iOS version only if you have saved your SHSH blobs (for the older iOS version) using either Cydia or TinyUmbrella (or even the “copy from /tmp during restore” method for advanced users).

    iPhone 4S downgrade still not available as it can't be jailbroken so far.


    How to downgrade 5.0.1 to 4.3.3 / 4.3.5 - iPhone 4, 3GS, iPod Touch 4G, 3G, iPad:


    Step 1: Make sure that you have downloaded the version of iOS which you gonna downgrade to (4.3.5, 4.3.3 or any iOS version).

    Step 2: Navigate to :
    Windows Users: Windows > System 32 > drivers > etc
    Mac Users : etc

    Open hosts file with the text editor then add the following code to the end of the file :
    74.208.105.171 gs.apple.com
