How to Downgrade iOS 6.0.1 to iOS 5.1.1 Using Redsn0w?

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.

Downgrade iOS 5.1.1 Tutorial

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:

  1. 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.
  2. 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).
  3. 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.
  4. Redsn0w-Run-As-Administrator

  5. On the main menu of Redsn0w, click the Extras button.
  6. Downgrade iOS 6.0.1 to 5.1.1 Redsn0w Main

  7. On the next screen, click Even More.
  8. Downgrade iOS 6.0.1 to 5.1.1 Redsn0w Even More

  9. Next, click Restore.
  10. Downgrade iOS 6.0.1 to 5.1.1 Redsn0w Restore

  11. 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.
  12. Downgrade iOS 6.0.1 to 5.1.1 Redsn0w IPSW

  13. 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.
  14. Redsn0w Prevent Baseband Update

  15. 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.
  16. redsn0w-0.9.15b3-DFU-Mode-Steps

  17. 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.
  18. Redsn0w will again get to work and restore / downgrade your device to iOS 5.1.1.
  19. 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.

The iPhone Dev Team has been hard at work in making various jailbreak processes more streamlined for users. In this case, the process of downgrading has been simplified, granted that you have all the requirements for the downgrade procedure.

      Unless you have updated to iOS 5.1.1 before and saved the blobs, I’m afraid you might have missed the boat on this one. This tutorial only works when downgrading with saved blobs. Nevertheless you will still require the necessary blobs for iOS 5.1.1 so you can upgrade.

    after some research on the web, there’s no way to backup from 6.0 to an old version!if you have important data on your phone just don’t downgrade, coz now I have to restore the newest iOS which doesn’t have jailbreak at all… if I knew it before I wouldn’t have downgraded my phone :(
