DownGrade iOS 6 to iOS 5.0.1, 5.1.1
We all were anxious to try iOS 6. Unfortunately, some users may regret upgrading to iOS 6. During the iOS 6 beta period downgrading was much easier but it also required a developer account for the most part. There were ways around upgrading and downgrading without a developer account but we aren’t discussing that here. If you are interested in Downgrading without a developer account during the beta period click this link.
iOS 6 offers some pretty amazing features. However, many of them are available in iOS 5 with a jailbroken device. That brings me to my next point. If you are running firmware iOS 6 and wish to downgrade to i/OS 5.1.1. It can be done but requires you have either saved your SHSH blobs through Cydia or locally. If you don’t have your blobs you will just have to wait until the iOS 6 jailbreak releases. Based on Pod2G’s comments at JailbreakCon 2012 I don’t foresee it anytime soon.
Be prepared for the next jailbreak and save your blobs. Watch the video here to learn how to save your blobs using TinyUmbrella. It can be used on eith Mac or PC.
Reverting back to iOS 5.1.1
1. Download the latest version of RedSnow which at the time of this article is 0.9.14b2 and the IPSW 5.1.1 file. Save these to your desktop for easy access later. Inside Redsnow there is a feature called SHSH blob stitching. However, you must have the blobs saved locally or in Cydia. So locate the blobs before beginning the process. After choosing the correct IPSW file and blobs, RedSnow will now stitch them together creating the firmware you will need to downgrade.
2. In Redsnow go back a couple pages until you can find or see PWNED DFU mode. Click on PWN DFU mode in order for iTunes to restore using the newly stitched blob firmware you just created.
3. Open iTunes and you should see you device in Recovery mode. This is the mode with the plug on the screen. Anyway iTunes should say something about seeing a device in Recovery mode. Hold option and click restore and choose the stitched firmware you just created. Allow iTunes to completely restore the device.
This will take several minutes and you may get a (-1 error) from iTunes but no biggee here. Open Redsnow and click Extras>Recovery Fix, put idevice back into DFU mode and the Recovery fix should run.
This may seem difficult but its actually very simple. Follow these directions completely and you should be fine. If you need extra help drop a comment.
