Now, judging the efficiency of a system based on just one factor – say, the Maps – is not something that we advocate. Barring Maps, iOS 6 really has some of the coolest features you could ask for, ranging from Facebook integration, changes in the Notification center to the way Siri works these days.
But to a lot of users, the Maps used to be a singularly important feature.
And then there are quite a few other minor problems for a specific set of users: battery, performance, App Store… well you get the drift, right?
That’s why Redsn0w’s downgrade tool for A4 devices is something that would be useful if you’re looking to downgrade from iOS 6 to iOS 5.1.1.
What You Need:
- An A4 device: iPhone 4, 3GS, iPod Touch 4G
- A saved SHSH blog: either on your local disk or in Cydia
- Redsn0w 0.9.14b2 (Windows / Mac)
- iOS 5.1.1 IPSW file for your device.
How to Downgrade to iOS 5.1.1 from iOS 6
To downgrade iOS 6 to iOS 5.1.1, we’re going to “stitch” the custom firmware with the SHSH Blob and then do a manual restore. Here’s how. It’s simple:
Step 1: Enter your iDevice in DFU mode and connect it to the system (ignore iTunes for the moment)
Step 2: Put the SHSH blob (if you’ve got it locally) and the custom IPSW file you downloaded in the same folder
Step 3: Download redsn0w and open it
Step 4: Choose Extras -> SHSH Blobs -> Stitch
Step 5: Choose the iOS 5.1.1 IPSW file you downloaded
Step 6: if you’ve got the SHSH blob locally, choose Local. Else, choose Cydia.
Step 7: Redsn0w will stitch them and create the custom iOS 5.1.1 firmware for you to use.
Step 8: After the stitching is done, go back to the Extras screen and choose “Pwned DFU”
Step 9: Now open iTunes
Step 10: From under the devices tab, your iPhone/iDevice will be shown as in Restore Mode.
Step 11: Press and hold “Shift”/ “Option” and click the Restore button.
Step 12: Choose the custom IPSW file that Redsn0w created
Step 13: An unknown error will appear. Head over to Redsn0w, choose Extras and then “Recovery Fix”
Step 14: Put your phone in DFU mode again and Redsn0w will finish the downgrade.
