Do you have an iPhone 3GS, iPhone 4 or iPod touch fourth generation with iOS 6 and want to revert to iOS 5.1.1? In this article we are going to offer you a step by step procedure to downgrade from iOS 6 to iOS 5.1.1. Unlike beta version of iOS 6 you must have your SHSH blobs for iOS 5.1.1 save for your device.
To downgrade from iOS 6 to iOS 5.1.1 you will need to use the latest version of Redsn0w. The program will use the “Stitching” to combine the IPSW file for iOS 5.1.1 with the corresponding device SHSH to downgrade. The process may seem difficult and confusing, but it’s actually easier than it looks.
Step 1: Download Redsn0w 0.9.14 beta 2.
Step 2: Download the iOS 5.1.1 IPSW file for the device on which you want to apply the downgrade.
- Download iOS 5.1.1 for iPhone 3GS
- Download iOS 5.1.1 for iPhone 4
- Download iOS 5.1.1 for iPod touch fourth generation
Step 3: Locate the SHSH of iOS 5.1.1 for your device that you saved earlier. Copy / paste it in the same folder in which you have saved IPSW file of 5.1.1.
Step 4: Put your device in DFU mode.
Step 5: Open RedSn0w and click on Extras, then click SHSH blobs and then click Stitch.
Step 6: Click on IPSW and select the iOS 5.1.1 IPSW file for your device that you downloaded earlier.
Step 7: If your SHSH are saved on Cydia server, click Cydia under blobs section. If you saved the SHSH locally, click Local and select the SHSH certificate of iOS 5.1.1 for your device.
Step 8: Once you have selected the IPSW file and SHSH certificates, 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 does not sign iOS 5.1.1.
Step 9: In RedSn0w, go back two pages, and click on Pwned DFU. This program will set up your device in Pwned DFU mode so that iTunes can restore the created firmware without errors. If you will skip this step you will receive the error 1600 during restore.
Step 10: Open iTunes and it should detect your device in recovery mode. Hold down the Option key or CTRL key and click Restore, then select the IPSW file you created earlier. The file name should be preceded by 13 numbers that represent the ECID of the device.
Step 11: Wait until iTunes completes the restore, and if you receive the error -1 do not worry. It’s all normal.
Step 12: Open RedSn0w, click Extras and then Recovery fix.
Step 13: Put your device again into DFU and the Recovery fix should run successfully.
Step 14: Once you have completed the process of Recovery fix, your device should be re-upgraded to iOS 5.1.1 and you will then have successfully completed the process of downgrading.
It is essential that you follow all the steps listed in the guide. Losing only one, the procedure will fail. To do this, remember, you must have an A4 device have your SHSH blobs saved locally on your computer, or stored on Cydia the latest version of Redsn0w and proper release of iOS 5.1.1 for the device you wish to downgrade.
Currently the downgrade from iOS 6 to iOS 5.1.1 is not possible on the iPad 2, iPad 3 and iPhone 4S.
