Jailbreak iOS 5.1.1 Using Dev Team’s CLI (Command Line Interface) Tool on Windows

iPhone Dev Team have packaged the pod2g’s Rocky-Racoon untether exploit into CLI (command line version) tool that will assist them in diagnosing issues (such as – iTunes errors, boot issues and other recovery loop problems) that may arise during the jailbreak process. Once the issues are ironed out completely, the solution will be packaged into redsn0w tool for stable and clean jailbreak.

Jailbreaking the 5.1.1 untethered using CLI tool requires a tiny bit of command line work, but it’s nothing most users can’t handle – or rather, everyone can handle. You’ll need a Windows computer for this particular method, but it’s really just a matter of plugging in your iOS device to be jailbroken and running a few commands. If you want to try this method, see the note, requirements and instructions below.

I would recommend you to try command line method only when you fail to jailbreak your device using Absinthe 2.0.1.

Note: If you’re iOS device is running iOS 5.1, you must upgrade it to 5.1.1 before you follow the steps to jailbreak; else you’ll not be able to jailbreak your iPhone, iPad or iPod touch (Note: Absinthe 2.0 doesn’t support iOS 5.1). This is done by downloading a stock IPSW from Apple and applying it with iTunes (preferably, the latest version of iTunes).

And, if you have already jailbroken your iPhone 4 or 3GS “tethered” using redsn0w, there is no need to re-jailbreak. You can simply install Rocky Racoon Untether 5.1.1 Package from Cydia to convert tethered jailbreak into Un-tethered. New users, however, have to follow the process below.

cinject -Y payloads_rocky

You will see following text messages. Sit tight as the tool is installing the payload. While you’re executing these commands, don’t touch your device. Just let the commands do their work.

Congratulations! You have successfully jailbroken iOS 5.1.1 IPSW on your iOS device untethered. Enjoy the many benefits of having a jailbroken Apple TV.

If you are getting unknown or strange errors with the CLI version, Try a restore to iOS 5.1.1 and try again. It should solve errors.
