How To: Downgrade iOS 5.1.1 To iOS 5.1, iOS 5.0.1 Or iOS 5.0 On iPhone 4/3GS, iPad 1G, iPod Touch 4G/3G

May 8, 2012 by Jaden Easton-Ellett 30 Comments

Apple released the iOS 5.1.1 firmware today featuring bug fixes and small stability improvements while taking HDR photos. Although we warned users to stay away from updating their iPhone, iPod Touch or iPad to the iOS 5.1.1 firmware, I am sure there are those who accidentally did.

Yes you can Jailbreak the iOS 5.1.1 firmware tethered with RedSn0w, but if you previously had an Untethered Jailbreak on iOS 5.0.1, a tethered Jailbreak just doesn’t suffice. Thus, if you are looking for a how to guide on how to downgrade from the iOS 5.1.1 firmware to the iOS 5.0.1 or iOS 5.0 firmware you are in luck!

In this how to guide from iJailbreak.com you will learn how to downgrade your A4 iOS device to the iOS 5.0.1 or iOS 5.0 firmware from iOS 5.1.1. Before we start however make sure you meet the requirements listed below.

iOS 5.1.1 Downgrade Requirements: 

  • If you have an iPhone 4, iPhone 3GS, iPad 1G, iPod Touch 4G, iPod Touch 3G then this how to guide will work for you. For those looking to downgrade their iPhone 4S or iPad 2 you are out of luck at this time unfortunately.
  • APTicket + saved SHSH blobs for the iOS 5.0.1 or iOS 5.0 firmware.
  • A Windows computer.

Downgrade From iOS 5.1.1 To iOS 5.0.1 / iOS 5.0

Step 1) – The first thing you will need to do is download a tool developed by iH8Sn0w called iFaith. What the iFaith tool does is dumps the SHSH blobs directly off your iPhone, iPod Touch or iPad for the firmware you are currently running. Allowing you to stitch together a custom firmware that can downgrade your iOS device to a previous firmware version Apple is not signing. If you are following this how to guide you most likely already used this tool to dump your iOS 5.0.1 or iOS 5.0 SHSH blobs.

Download iFaith 1.4.2 (Windows)

Step 2) – The next thing you will need to do is run iFaith (click the OK button once you have read the warning).

iFaith v1.4.2 Windows

Step 3) – With iFaith up and running you will need to click the Build *signed* IPSW w/ Blobs button.

iFaith v1.4.2 Windows

Step 4) – Upon clicking the button previously mentioned you will need to browse for the saved SHSH blobs file that was created when you saved your SHSH blobs for the iOS 5.0.1 or iOS 5.0 firmware.

iFaith v1.4.2 Windows

Step 5) – It is now time to browse for the iOS 5.0.1 or iOS 5.0 firmware file. Depending on which SHSH blob file you selected you will need to select either the iOS 5.0.1 firmware file or iOS 5.0firmware file (download iOS firmware files here).

iFaith v1.4.2 Windows

Step 6) – After you have selected the right firmware file iFaith will begin creating your custom firmware file.

Step 7) – When your custom firmware file has been created go back to the iFaith main menu (if you are not there already) and click the Use DFU Pwner (iREB) button. Now simply follow the instructions presented to you for putting your iPhone, iPod Touch or iPad into pwned DFU mode.

iFaith v1.4.2 Windows

Step 8 ) – With your iOS device in pwned DFU mode you will need to launch iTunes and restore your iPhone, iPod Touch or iPad to the custom firmware file you created. This can be done by Option (alt) clicking the Restore button on Mac OS X or by SHIFT clicking the Restore button on Windows.

If you experience iTunes Error 3194 then you can click here to follow another how to guide on how to fix it. For those that got success, congratulations! You have now downgraded your A4 iOS device from the iOS 5.1.1 firmware to either the iOS 5.0.1 firmware or the iOS 5.0 firmware. To Jailbreak your iOS device untethered click here to go to iJailbreak’s How To Jailbreak Section. If you have any further questions or concerns please leave them in the comments section below.

    I’ve messed up my AppleTV2. I’ve tried to JB, but it didn’t work. Only thing I can do is reinstall through Itunes. If I do that will it automaticly install 5.1.1 or can I choose 5.1?

    You’re already too far into your mess. Literally, it is too late to downgrade anything whatsoever. But, on the plus side, this can serve as a lesson to save your SHSH files whenever can. Also, there won’t likely be a jailbreak for the 5.1.X firmwares due to the close release of the iOS 6

    You can chose. When restoring in itunes, hold down shift then click restore. And select the 5.1 firmware.
