For a jailbreak user, while it is attractive to update to the latest firmware and experience all those new changes and features, there will always be the desire to go back to the most stable untetethered jailbreak. However you look at it, a stable untethered jailbreak is preferred above the latest tethered jailbreak. Take iOS 6 for example. As of now, the jailbreak for iOS 6 is very limited and tethered and it only works on A4 devices. If you are someone who has upgraded to the latest iOS 6.0.1 firmware, then you'll be happy to know that you can downgrade to iOS 5.1.1 (with the most stable untethered jailbreak) using Redsn0w. This guide will teach you How to Downgrade iOS 6.0.1 to iOS 5.1.1 Using Redsn0w.
Requirements to Downgrade iOS 6.0.1 to iOS 5.1.1:
- You can only perform this downgrade procedure if you have an A4-based device like the iPhone 4, iPhone 3GS and iPod touch 4G. Otherwise, you can't use this guide.
- IMPORTANT: Apple has already stopped signing the window for iOS 5.1.1 which implies 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 6.0.1 to iOS 5.1.1 Using Redsn0w:
- First step is to download the latest version of Redsn0w for either on Windows or Mac (this guide works on both). Download links for Redsn0w 0.9.15b3 can be found here.
- On top of that, you will also need to download the IPSW file of the iOS version which you'll be downgrading into. In this case, its iOS 5.1.1 (direct download links).
- Extract the Redsn0w file you have downloaded in Step 1. Launch Redsn0w by double-clicking the redsn0w.exe file. For good measure, run the Redsn0w executable as an administrator.
- On the main menu of Redsn0w, click the Extras button.
- On the next screen, click Even More.
- Next, click Restore.
- Click IPSW and you will be prompted to browse for the IPSW file you are intending to downgrade into. Again in this case, it is iOS 5.1.1.
- If you rely on Ultrasn0w unlock, make sure that you click Yes when prompted by Redsn0w to "Prevent Baseband Update?" Then click OK on the following Pwned DFU screen.
- Connect your device to the computer and you will be required to place it under DFU Mode. Just follow the onscreen instruction of Redsn0w and you should do fine.
- Once Redsn0w detects your device in DFU Mode, it will be exploited with Limera1n. The program will then search for your saved iOS 5.1.1 SHSH blobs via Cydia. If Redsn0w can't find the required SHSH blobs, point it manually if you have saved it locally on your computer.
- Redsn0w will again get to work and restore / downgrade your device to iOS 5.1.1.
- After several minutes, the program will show you a notification that the restore process has been successful. Now that you are back in iOS 5.1.1, you can now perform the latest stable untethered jailbreak.
