  • How to Jailbreak Using redsn0w 0.9 (Windows)


    {last updated November 1st, 2012}

    This Windows only guide (OS X guide here) will teach you how to jailbreak various devices using redsn0w 0.9. The current version of redsn0w 0.9 is 0.9.15b3. Note this is an UNTETHERED JAILBREAK (with the exception of 4.3.4/4.3.5/5.0 where it is a tethered jailbreak), meaning you can reboot your phone just like you normally would.

    This guide should be used with the following device/firmware combinations (if you're not sure, here's how to find your iOS firmware version and how to find your iOS device type):
    • iPhone 3G | 4.3.4
    • iPhone 3GS | 4.3.3
    • iPhone 3GS | 4.3.4
    • iPhone 3GS | 4.3.5
    • iPhone 3GS | 5.0
    • iPhone 3GS | 5.0.1
    • iPhone 4 | 4.2.9
    • iPhone 4 | 4.2.10
    • iPhone 4 | 4.3.3
    • iPhone 4 | 4.3.4
    • iPhone 4 | 4.3.5
    • iPhone 4 | 5.0
    • iPhone 4 | 5.0.1
    • iPad 1 | 4.3.3
    • iPad 1 | 4.3.4
    • iPad 1 | 4.3.5
    • iPod touch 3G | 4.3.4
    • iPod touch 3G | 4.3.5
    • iPod touch 4G | 4.3.4
    • iPod touch 4G | 4.3.5
    • iPod touch 4G | 5.0
    • iPod touch 4G | 5.0.1
    If you prefer the simpler version of this guide with no pictures, click here.

    Alright, let's get started. First thing you'll need to do is download the Windows version of redsn0w 0.9.15b3 from mod.my/redsn0wwin0915b3. Double-click the zip file to unzip it, and open the redsn0w folder to see the redsn0w.exe file.



    Making sure your device is connected, double-click redns0w to launch it. You will see the redsn0w home screen - press the Jailbreak button.



    Before you do anything on the next screen, power off your device by pressing and holding the sleep button (the button on the top) until the slide to power off screen comes up. Slide to power off. NOTE: As of iOS firmware 5.1.1, this step is not necessary.



    Alright, NOW you can press Next on the redsn0w page which tells you to power off your device. NOTE: redsn0w will IMMEDIATELY ask you to press and hold the sleep button on the device, then continue holding it while pressing the home button, then continue holding the home button while letting go of the sleep button. Make sure your device is in your hands before pressing Next in redsn0w. NOTE: As of iOS firmware 5.1.1, this step is not necessary.



    After successfully following the prompts of holding buttons down (this is entering DFU mode for the device), redsn0w will tell you it is Exploiting with limera1n. You can now let go of the home button on your device. NOTE: As of iOS firmware 5.1.1, this step is not necessary.





    redsn0w will go through a few screens, telling you it is waiting for a reboot, then popping up a new window with various status messages as it jailbreaks your device.





    Once that is done, you'll be shown a screen asking what you'd like to do. The default action (which we'll be doing in this guide) is to Install Cydia. You're welcome to check any other boxes you'd like, but please only do so if you know what you're doing. Press Next when you've selected your choices.



    redsn0w will now tell you Uploading ramdisk, which will take a few seconds, and then say Done! Once it says Done! it is safe to close redsn0w, as the rest of the jailbreak process will happen on the device itself.





    Your device will now scroll a bunch of command line messages as the jailbreak completes. After a minute or so of the scrolling text, you will see the pwnapple logo with some more status updates (the final step before your jailbreak is complete).





    That's it! You're now holding a jailbroken device. Not too bad, eh?

      I upgraded from OS 4.1 to 4.3.5. iTunes did not load my contacts, address book and emails. This info came from the OS 4.1 back and did not transfer them? How do I get this information?

      Make sure you chose the correct backup file first, there are probably a few of them. If still nothing you can try juicephone or iphone backup extractor to see if you can get your stuff manually from one of your backups.

      Where do I locate these backup on my computer?

      Tried upgrading from OS 4.1 to 5.0.1. All attempts failed. I was able to upgrade from OS 4.1 to 4.3.5. I still can't upgrade from 4.3.5 to OS 5.0.1. I have tried everything, including holding down shift key and directing it to the 5.0.1 file. Always fails. Looking for some assistance with this. Lastly, is there a 4.3.5 untethered jailbrake?

      You need to be more specific with what is happening. What errors are you getting when trying to go to 5.0.1? What device do you have? Do you need to unlock or are you on official carrier.

      No there is no untethered jailbreak for 4.3.5. But there is for 5.0.1.

      Hi,

      I am having an issue with upgrading 3gs 4.3.5 to 5.0.1 as well. 1st, I used the guide on this thread and while it says "UNTETHERED JAILBREAK, meaning you can reboot your phone just like you normally would..." mine is tethered unless I've just missed something. I know 4.3.5 had probs finding an untethered JB. But when I turn my phone off manually I can't access cydia or safari, and I also got the msg at the end of the JB that it was tethered. Any ideas?

      But really the only reason I was jailbreaking was to save my blobs so I could update to 5.0.1, but I get "error 21 unable to update.." I've poked around trying to find the answer for the better part of a day, but now I'm asking...help!

      Thanks

      I started at OS 4.1 on my iPhone 4 and was not successful at making the upgrade to 5.0.1. However, I was able to make it to 4.3.5 but unfortunately a tethered JB OS. I then downgraded to OS 4.3.3 and JB it. Everyone says just let iTunes upgrade u to 5.0.1 but iTunes always fails and error's.
