Note: If you are Windows user then don’t forget to Run the tool as Administrator.

But if you want to start making iOS 5.1.1 downgrade then first listen to me.You need to back up SHSH blobs of the iOS firmware to which you want to downgrade to. You may want to downgrade new iOS 5.1.1 on A5 (A5X) devices because there is no untethered jailbreak for new iOS yet.

To back up SHSH blobs is essential thing for downgrade. If you are downgrading your iOS to lower firmware you have to supply Apple with SHSH blobs of the lower version for certification. If all goes correct and Apple servers take shsh files and approve them you’ll be able to use iOS firmware you want.

Without SHSH blobs saved you can’t to perform downgrade. That’s why it is important to save them.

    Oh is there any how to Downgrade guide?

  3. Michael says:

    I don't understand. The New Ipad (A5x Idevice) came pre-installed with IOS 5.1. Therefore mine doesn't have saved ShSH Blobs.
    How do I go about downgrading? As far as I know, all New Ipads are on 5.1 with no previous blobs?

  4. Andy says:

    It is sorry to say but yes, you can't downgrade your new iPad to iOS 5.0.1 or lower. You can only downgrade iOS 5.1.1 (if you want to update your iOS) to 5.1 and that's it.
