It is no secret that there have been users who are dissatisfied with the latest iOS and would take the opportunity to downgrade iOS 6 to iOS 5.1.1. At this point, the iOS 6 jailbreak is still pretty much spotty at best and obvious that it is still a work in progress. Aside from the fact that it only works with A4 devices (iPhone 4, iPhone 3GS and iPod touch 4G), the jailbreak does not even install Cydia by default. And there's the fact that it is a tethered jailbreak. Truth be told, iOS 6 is simply not the most attractive choice for jailbreak users at this time. Fortunately, we have a guide on How to Downgrade iOS 6 to iOS 5.1.1 Using Redsn0w.
So why iOS 5.1.1? For users who want to downgrade from iOS 6, iOS 5.1.1 is the best version to fall back to because it has the latest and most stable untethered jailbreak available. Downgrading iOS 6 to iOS 5.1.1 is a fairly easy task, provided that you have fulfilled all the requirements.
Requirements to Downgrade iOS 6 to iOS 5.1.1:
- This guide is only applicable to A4-based devices which include the iPhone 4, iPhone 3GS and iPod touch 4G.
- IMPORTANT: Apple has already stopped signing the window for iOS 5.1.1 which means that you won't be able to downgrade using the conventional iTunes restore method. So before you can hope to use this guide, make sure that you have saved your SHSH blobs for iOS 5.1.1, either locally or through Cydia. Otherwise, there is no hope for you to downgrade.
Steps on How to Downgrade iOS 6 to iOS 5.1.1 Using Redsn0w:
- Download the latest public release version of Redsn0w [Download Redsn0w 0.9.14b2].
- Download the iOS 5.1.1 IPSW file that corresponds to the device you wish to downgrade. Download links can be found here.
- After you have downloaded the iOS 5.1.1 IPSW file, you should locate the SHSH blobs of your device if you have saved it locally. Place the blobs in the same folder as the iOS 5.1.1 firmware file. If you have saved your blobs in Cydia, then you can proceed to the next step.
- Launch RedSn0w 0.9.14b2 and on the main screen click Extras.
- Click SHSH blobs and on the next screen, click Stitch.
- In this screen, this is where you will use the iOS 5.1.1 IPSW file you've downloaded earlier and your saved SHSH blobs. Click IPSW and you will be prompted to browse for the iOS 5.1.1 IPSW file.
- If you have saved your blobs in Cydia, then click the Cydia button. If you have saved your blobs locally, click the Local button and browse for your blobs.
- Once both components are selected, Redsn0w will now stitch a custom firmware file for iOS 5.1.1 which contains your SHSH blobs. This will enable you to downgrade to iOS 5.1.1 despite the fact that Apple has stopped signing it.
- Now we need to place your device in Pwned DFU mode, so that we can use the stitched firmware to restore your device. Otherwise, you will encounter an iTunes 1600 error. In Redsn0w, click the back button twice and click the Pwned DFU button. Just follow the onscreen instructions to place your device in Pwned DFU mode.
- Launch iTunes and it should detect your device in Recovery mode. Hold the SHIFT (Windows) / Option (Mac) and click the Restore button. Select the stitched firmware we have created earlier through Redsn0w. You can tell the file apart because it is prefixed by a series of numbers which is actually your device ECID.
- iTunes will now restore your device and you will encounter an iTunes Error -1. Don't be alarmed, this is normal.
- Launch Redsn0w again and this time click Extras > Recovery Fix. You will be required to place your device in DFU Mode so Recovery Fix can commence.
- After the Recovery Fix process is completed, you should have downgraded your device to iOS 5.1.1.
And with that, you are done! Again, this is only applicable for folks who have A4 devices and have saved the iOS 5.1.1 SHSH blobs. Now you can jailbreak your device and enjoy the most stable untethered jailbreak as of now.
