How to Downgrade iOS 5.1.1 To iOS 5.0.1for A5 or A5X using Redsn0w 0.9.11b1

Step 1: Connect your iPhone 4S, iPad 2 or iPad 3 to computer and back up your data.
Step 2: Launch Redsn0w 0.9.11b1 and got to Extras>Even more> Restore



Step 3: Select the firmware file which you want to downgrade to
Remember that you will still need iOS 5.1.1 IPSW file because this technique first updates your iOS device to latest iOS firmware version and then downgrades your iOS device to lower firmware version.

Step 4: If you have your SHSH blobs saved locally on your computer then select Local and point redsn0w to your locally saved blobs otherwise select Remote option

Important: You must have SHSH blobs saved either locally or on Cydia for this technique to work.
Step 5: Redsn0w will start cooking your IPSW file with saved SHSH blobs for restoration. This process can take a while so just stay put don’t touch anything.

 You can download the RedSn0w 0.9.11b1 from here.
