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.
