Do you have an iPhone 3GS, an iPhone 4 or a 4th generation iPod touch with iOS 6 and you want to return to iOS 5.1.1?

Here is the guide for you.

If you have installed iOS 6 on iPhone 4, 3GS and iPod Touch but now you want to go back to the previous version of the operating system, here in this guide we explain how to install iOS 5.1.1 again.

As we said, in this article we explain in detail the procedure to follow to downgrade from iOS 6 to iOS 5.1.1.

Compared to the beta version of iOS 6, in fact, things have changed: SHSH certificates will now be required for the firmware to be restored and NOT all devices are supported. For example iPads and iPhone 4S cannot downgrade from iOS 6 to iOS 5.1.1, at least for now.

That said, let's get started downgrade from iOS 6 final to iOS 5.1.1 you need to use the latest public version of Redsn0w.

The process may appear difficult and unclear, but in reality simpler than it seems and will not take more than a few minutes.

Let's begin.

How to downgrade from iOS 6 to iOS 5.1.1 (Guide)

Step 1: Download RedSn0w 0.9.14b2 for Windows or for Mac:

  • Redsn0w 0.9.14b2 for Mac;
  • Redsn0w 0.9.14b2 for Windows.

Step 2: Download the IPSW file for iOS 5.1.1 and for the device on which you want to install it (download).

Step 3: Find the iOS 5.1.1 SHSHs for your device that you previously saved via TinyUmbrellaoiSHSHit. You must have necessarily saved these certificates before the release of iOS 6 or immediately after, otherwise you will not be able to downgrade in any way.

Step 4: Put your iPhone in DFU mode.

Step 5: Open RedSn0w and click on Extras, then on SHSH blobs and finally on Stitch.

Step 6: Click on IPSW and select the iOS 5.1.1 IPSW file for your device that you previously downloaded.

Step 7: If your SHSH are saved on Cydia's servers, click on the item of the same name in Redsn0w in the section dedicated to certificates. If you saved the SHSH locally, click on Local and choose the iOS 5.1.1 SHSH certificate for your device.

Step 8: Once IPSW and SHSH certificates have been selected, Redsn0w will start creating a custom firmware for iOS 5.1.1. You can use this file to restore to iOS 5.1.1 and then to downgrade, even if Apple no longer signs iOS 5.1.1.

Step 9: In RedSn0w, go back two pages, and click on Pwned DFU. This function of the program will set your device in Pwned DFU mode so that iTunes can restore the firmware created without errors. If you skip this step you will receive error 1600 in the recovery phase.

Step 10: Open iTunes which should detect your device in DFU mode. Hold down the Option or CTRL key and click on Restore, then select the previously created IPSW file. The file name should be preceded by 13 numbers representing the device's ECID.

Step 11: Wait for iTunes to complete the restore and if you get the error -1 don't worry. all normal.

Step 12: Open RedSn0w, click on Extras and then on Recovery fix.

Step 13: Put your device back into DFU and Recovery fix will perform the procedure correctly.

Step 14: Once the Recovery fix procedure is completed, your device should be updated to iOS 5.1.1 again and you have successfully completed the downgrade procedure.

It is absolutely essential to follow all the steps listed in the guide.

To do this, remember, you'll have to necessarily have an A4 or previous device updated to iOS 6 with the unique SHSH certificates for that device saved on the computer or on Cydia.

ATTENTION, IMPORTANT: Currently the downgrade from iOS 6 to iOS 5.1.1 is not possible on iPad 2, third generation iPad and iPhone 4S.
