How To: Jailbreak iPhone 4S Untethered On iOS 5.0, 5.0.1 With CLI [Windows]

Earlier today we told you that the command line interface (CLI) version of the iPhone 4S Untethered Jailbreak was released for Windows. While most Jailbreaking solutions onwards from 2010 have generally been released with a GUI (graphical user interface), the initial release of the Windows A5 Untethered Jailbreak will require you to use the Windows command prompt. This is partly because the iPhone 4S Untethered Jailbreak has proved to be one of the most complicated Jailbreaks ever developed, and at this time the Dream Team are still trying to port Absinthe to Windows.

If you are not skilled with the Windows command prompt then you will be glad to know that in this how to guide from, you will learn how to Jailbreak your iPhone 4S on the iOS 5.0 or iOS 5.0.1 firmwares (9A405 and 9A406) using CLI on the Windows operating system.

Update #1: How To: Jailbreak iPad 2 Untethered On iOS 5.0.1 With CLI [Windows]

Update #2: A GUI version of CLI has been released in the form of Absinthe v0.2 (Click here for a How To guide).

Perquisites: The very first thing you need to do before starting this how to guide is make sure your iPhone 4S is backed up. As the CLI Jailbreaking tool for Windows was just released, there is a good chance that you may experience an error Jailbreaking it. Thus, it is always a good idea to make sure all your content on your iPhone 4S is backed up. Additionally, if you iPhone 4S has a passcode lock you must disable it, and furthermore you will need to disable any current VPN’s setup on your iPhone 4S.

Recommendation: It is our personal recommendation that you simply restore your iPhone 4S to factory settings on the iOS 5.0.1 firmware (if you do not require an unlock) or the iOS 5.0 firmware (if you do require an unlock). This will dramatically reduce the chance you have of experiencing an error while Jailbreaking it with CLI for Windows.

Step 1: The first thing you will need to do is download the latest version of CLI from the iPhone Dev-Team’s blog (see update 3) by clicking here. Additionally, you can use the direct download link by clicking here if it proves to be more convenient.

Note: Before moving on to step 2 please make sure your iPhone 4S is plugged into your computer via your USB cable.

Step 2: The next you will need to simply unzip the cinject_0.4.3 folder into your system directory (C:/).

Step 3: Now you will need to search for CMD through your start menu, right click on it, and then click the Run as administrator option.

Step 4: With the Windows command prompt interface now open you will need to type in the following command to get into the proper folder.

CD C:\cinject_0.4.3

Step 5: After going into the proper folder through command prompt you will now need to type in another command as shown in the quoted area below.

cinject -i payloads/jailbreak.mobileconfig

Step 6: Once you have typed the above command you will notice an install profile window appears on your iPhone 4S. You will need to simply tap the install button, ignore the password screen and simply tap next button on your iPhone 4S to install this special Jailbreak profile.

Step 7: After the profile has been installed you will need to type in another command into Windows command prompt.

cinject -j payloads

Step 8: You now need to execute yet another command through Windows command prompt.

cinject -w

Step 9: Now go into the on your iPhone, into the General Tab, then into the Network Tab, and finally you should see a VPN toggle. You will simply need to toggle VPN to the ON position and then you should notice you receive an error “A configuration error occurred.” Tap the OK button and your iPhone 4S should reboot.

Step 10: Once it has rebooted you will notice Cydia on your SpringBoard (homescreen). This means the Jailbreak worked and you now have a Jailbroken iPhone 4S running the iOS 5.0 or iOS 5.0.1 firmware. Congratulations!

We hope this how to guide has helped you Jailbreak your iPhone 4S running the iOS 5.0 or iOS 5.0.1 firmware using CLI for Windows. If you have any questions or thoughts related to this tutorial leave them in the comments section below…
