If you have an iPhone 4, iPod touch running on iOS 6 and would you like to downgrade it from iOS 6 to iOS 5.1.1? To do so you must have stored the SHSH blobs for iOS 5.1.1 for your iDevice because Apple has stopped the signing of iOS 5.1.1.
Using RedSn0w 0.9.15b3 we can restore to iOS 5, all devices for which we possess the certificate for any iOS 5, excluding those who have never had iOS 5. Here’s the list of supported devices:
- iPhone 4S
- iPhone 4
- iPhone 3GS
- iPad 3Gen
- iPad 2
- iPod touch 4Gen
- iPod touch 3Gen
The device must have installed iOS 5, any minor release. According to what stated by the dev-team on their blogs you can restore from any iOS 5 to any other iOS 5 (up or down) on all devices if you have correct blobs.

Follow the steps below on how to downgrade iPad, iPhone and iPod touch from iOS 6 to iOS 5.1.1.
1. Download Redsn0w from above links and save it on your desktop.
2. Download IPSW file of iOS 5.1.1 for the device you want to downgrade.
3. Locate SHSH blob of iOS 5.1.1 and place it in the folder in which you stored ISPW file of 5.1.1 on your local computer, if your blob are stored on Cydia, then continue on.
4. Place your iDevice running on iOS 6 in DFU mode.
5. Open Redsn0w, click Extras, SHSH Blobs and then on Stitch.
6. Click IPSW and select iOS 5.1.1 iPSW for your iDevice.
7. If you have stored SHSH blobs on Cydia, click on Cydia button under the blobs section and if it is stored on local system, click on Local and select SHSH blob for iOS 5.1.1 for your iDevice.
8. Once you have selected IPSW and blob, Redsn0w will start stitching them, as a result of which we will have a custom iOS 5.1.1. This custom created firmware will help us to downgrade.
9. In Redsn0w, click the back button twice and press Pwned DFU button. This step will place your iDevice in Pwned DFU mode so that iTunes can restore using stitched firmware. Without placing your device in Pwned DFU mode you’ll get an error 1600 in iTunes.
10. Start iTunes and it should detect your iDevice in Recovery Mode. Hold Option and click on Restore and then select your custom created stitched firmware. The filename should be prefixed by a series of 13 numbers, which is the device’s ECID.
11. Now iTunes will perform a couple of steps automatically after which your iDevice will be completely restored, and you may be greeted with an error-1 from iTunes but don’t worry.
12. Start Redsn0w, click on Extras and then on Recovery Fix.
13. Again place your device in DFU mode and the Recovery Fix should run successfully.
14. On completion of Recovery fix your device will be completely restored to iOS 5.1.1.
