Newer devices like the i Pad 2, i Pad 3, i Phone 4S, i Phone 5 and i Pod Touch 5G has different restrictions however, because they are not vulnerable to the limera1n exploit and are governed more-so by APTickets.These devices can only be downgraded on the i OS 5 firmware generation and require saved SHSH blobs and APTickets for the i OS 5 firmware version you are currently running and are trying to get to.

Unlike SHSH blobs which would submit the same one already stored on the server, a brand new APTicket is generated using a random string. Additionally, you will also learn the best way to save your SHSH blobs which will allow you to downgrade your i Phone, i Pad, i Pod Touch and Apple TV firmware version in the future.Simply scroll through our section for the firmware version you are trying to downgrade to, and read one of our easy to follow how to guides on downgrading your i Phone, i Pod Touch, i Pad, Apple TV or even Play Station.To do this you can use tools like Tiny Umbrella (download) and i Faith (download).It is important to keep in mind that these tools can even save the SHSH blobs of non-Jailbroken devices.Just like how Jailbreaking is becoming more and more difficult on newer Apple devices, so is downgrading.

As new exploits are constantly being found however, keep an eye on our list of how to guides shown below that will give you step-by-step instructions on how to downgrade your i Phone, i Pod Touch, i Pad or Apple TV to a lower firmware version.

Whenever you upgrade or downgrade your i Phone, i Pod Touch or i Pad, new SHSH blobs have to be generated because one of the parts to the SHSH formula is the firmware version.

In order to prevent firmware restores Apple only signs one firmware version at a time, which is obviously the latest firmware version available.

Once you have your SHSH blobs signed, as stated previously, if you upgrade to a new firmware version and decide you don’t like it you can downgrade back to the firmware version which you have saved SHSH blobs for.

There is unfortunately some restrictions that need to be kept in mind though.

If you are Jailbroken then most of the times your SHSH blobs are already saved on Cydia’s server automatically and you shouldn’t have to back them up manually.
