How To: Jailbreak iOS 5.1.1 Using GreenPois0n Absinthe 2.0

How To: Jailbreak iOS 5.1.1 Using GreenPois0n Absinthe 2.0

Earlier today the Jailbreak Dream Team released its latest iOS jailbreaking tool for iOS 5.1.1 called Absinthe 2.0. This jailbreak release has gained more attention than usual because of its ability to jailbreak the newest iPad which has never been done before. It also allows everyone to update their devices to the latest version of iOS, which fixes security issues and bugs. Read on to learn how to jailbreak your iOS device running iOS 5.1.1!

Before You Begin

If you’re already running a tethered version of the iOS 5.1.1 jailbreak, you should not follow this tutorial. Instead, you should use the Rocky Racoon tool to convert your tethered jailbreak to an untethered jailbreak. Simply open Cydia, search for “Rocky Racoon 5.1.1 Untether” and install it. Reboot your device to ensure it’s untethered. That’s it! Enjoy your iOS 5.1.1 untethered jailbreak.

Note: Do not uninstall the Rocky Racoon package from Cydia. Your untethered jailbreak now depends on the package, and if it’s uninstalled your device will no longer be untethered.

What You’ll Need

  • Any iOS device running iOS 5.1.1 except the Apple TV and the newest model (R2) of the iPad 2 WiFi
  • GreenPois0n Absinthe 2.0.4 for Windows, Mac OS X, or Linux
  • Latest version of iTunes
  • iOS device USB cable and computer


Sync your iOS device to your computer with iTunes so we can use this backup later. Skipping this step could result in losing recent apps, data, contacts, etc.


If your iOS device is not currently jailbroken, then proceed to Step Three. If you are jailbroken, read on.

Now that you’ve made a backup of your iOS device, you’ll want to either make a backup of your Cydia packages or create a list the packages you have installed so you can reference it later and download them. If you want to backup your Cydia packages, I recommend downloading PKGBackup ($7.99) from the BigBoss repo in Cydia. My preferred method of “backing up” my Cydia packages is simply taking screenshots of my listed Cydia packages under Manage > Packages in Cydia.


Now that we’ve made a backup with iTunes and our jailbreak packages, we have to wipe our device clean. Unlock your iDevice and open the Settings app. Scroll to General > Reset and tap the Erase All Content and Settings button. If you have a passcode set up, enter in your passcode to confirm you want to erase all content and settings. Then tap the red Erase iPhone (or iPad, etc.) button. Your device will reboot and display the loading circle.

According to Apple, this process can take “a few minutes to several hours”. Due to the possible longevity of this step, be sure your device is plugged into a power source during the erasing process. I tried using this process on my jailbroken iPhone 4S, and 16 hours later my phone was still displaying the loading circle. It was obvious that nothing was really happening behind that spinning circle, so I put my iPhone into DFU mode, restored it as a new iPhone on iOS 5.1.1, and then ran the erasing process again. It was just 5 minutes later and my phone was erased and set back to its defaults.


Once your device is done erasing, you’ll have to update it to the latest version of iOS – 5.1.1. Open up iTunes again and click the Update button inside your device’s menu. iOS 5.1.1 will begin downloading in iTunes. Once completed your iDevice will begin updating to iOS 5.1.1. When prompted to Set up as a new iPhone or choose from a previous backup, choose the backup we created earlier and restore your phone.


Download Absinthe 2.0.4 for Windows, Mac OS X, or Linux if you haven’t already. Once it’s finished downloading, extract your copy of Absinthe 2.0.4. If you’re running Windows, double-click the zip file and click Extract All or right-click and choose Extract Here with WinRAR. If you’re running Mac OS X, double click the zip file.


If you’re running Windows, right-click on the file we just extracted called “absinthe-win-2.0.4.exe” and click Run as administrator. If you’ve jailbroken your iOS device in the past, you’ve probably noticed that this step is new to the jailbreak process. Instead of the .exe file running the jailbreak program like before, this .exe is a self extracting .exe that contains the real .exe that runs the jailbreak program (that’s a lot of .exe’s, right?).

After you click Run as administrator, a command prompt window will open and the file will begin extracting the jailbreak files inside a new folder called “absinthe-win-2.0.4″. Inside this folder is the jailbreak program called absinthe.exe”.


Ensure that your iDevice is plugged in and ready to be jailbroken. If you have a passcode set, now is the time to remove it by going to the Settings app > General > Passcode Lock > set to Turn Passcode Off. Now right-click on the “absinthe.exe” file on your computer and click Run as administrator. Absinthe will detect your iDevice type. Once you click the Jailbreak button, iTunes will close and the jailbreak process will begin.


The jailbreak process should take about 5 minutes depending on your computer and iDevice. During the jailbreak process, your iDevice will display the Restore in progress text and will restart. Once its completed Absinthe will read Done, enjoy!. You can close the Absinthe program now. On your iDevice, you’ll notice Cydia on your springboard. Tap to open it up and let it creating the filesystem.

That’s it! Your iDevice now has the latest version of iOS and is jailbroken with GreenPois0n Absinthe! Don’t forget to reinstall all your Cydia packages.

    Actually didn’t bother backing up my Cydia apps, only wanted my intelliscreenX and cydia remembers your purchased apps. And I didn’t reset my phone, it hardly made a difference, compared to doing it.

      I ran the Erase All Content and Settings process for 16 hours last night. It kept going… and going… and going… finally I hard rebooted it and it came back up as if nothing happened. So I just restored it as a new phone, erased it again, restored from latest backup, and then jailbroke it. I’m not sure why the dev teams are telling people to erase… but there must be a good reason.

        I think originally it was to combat the hanging issue, and they said something about it being faster.

    I have tried everything and my device will not jailbreak

    Performed the break on my iphone 4 running ios 5.1.1 last night. Did this step by step through greenpois0n and when i press the cydia app the screen will slightly go black, but the app will not open. all other apps work fine. What am I to do?

    • Patrick Bisch

      Don’t backup your iPhone using an old backup in Step Four. Instead, try a clean install first. Then jailbreak it again. Does Cydia open now?
