How to Jailbreak iOS 4.3.1 Untethered Using Redsn0w 0.9.6 RC9 [HowTo Guide]

In this post we are going to show you in a step by step guide how you can jailbreak (untethered) iPhone 4, iPad 1, iPhone 3GS, iPod Touch 3G, iPod Touch 4G and Apple TV2 running on iOS 4.3.1 using the latest Redsn0w 0.9.6 RC9 version.

And if you have got iPad 2, don’t try this method as it is not compatible with this device at present.

Note: All those users who rely on unlock must not update their devices to stock iOS 4.3.1 iPSW file otherwise they will lose the unlock ability. They can use PwnageTool 4.3 to build the custom iOS 4.3.1 iPSW file and restore to it.

Step 1: Download the stock iOS 4.3.1 restore iPSW file for iPhone, iPad or iPod device.

Step 2: Update or restore to this download iOS version using the latest iTunes 10.2.1.

Step 3: Launch Redsnow 0.9.6 RC9 and point it to the official stock iOS 4.3.1 iPSW file which you have already downloaded in step 1.

Step 4: Reds0w will identify the file and prepare the jailbreak data.

Step 5: After clicking on Next, select the “Install Cydia” option and click on Next again.

Step 6: At this stage make it sure that your device is both OFF and plugged in and click on Next button.

Step 7: Follow the on-screen instruction to put your device into DFU mode.

Step 8: Now sit back and let Redsn0w do its work. Once your device is jailbroken it will restart automatically and you will see the Cydia icon on the screen of your idevice.

    how to restore ispw file (ios 4.3.1) for iphone?

  6. Sebastiansays:

    what do you do after you have Cydia installed in your iphone..sorry first time! thanks

    1. I launch it and install my faviourit tweaks like ManualCorrect, iAnnounce, FakeOperator, Tab+ and apps like Activator, Winterboard etc and themes….

  7. Xiosays:

    I ‘ve a problem i did everything you said and it succeeded, but at the reboot the apple icon didn’t turn into a skull and the cyndia icon is white and it just crashes when i launch it…

  8. Xiosays:

    will this work for 4.3? I can’t update it to 4.3.1 cuz 4.3.2 is out…and when i launch 4.3.1 ipsw file itunes ask me if i want to update to 4.3.2…

    1. If you have saved SHSH blobs for iOS 4.3.1, then its possible. First download the required iPSW file and then use the restore button while keep pressed Option key on Mac or Shift key on Windows. Please search for how to downgrade iOS 4.3.1 on this blog. The instructions are same.

  10. Shahryarsays:

    In my PC redsnow stops working while creating ram drive, just after restarting the iphone.

    Please help, my phone is locked now.

    1. I need more details before I can help you like iPhone model, iOS you want to jailbreak, Windows or Mac PC, do you rely on unlock or want only jailbreak etc.

      1. Chrismicheal01says:

        even i have the same issue … iam on iphone 4 , 4.3.1… windows vista …

  11. Funkysolosays:

    when i click on cydia nothing happens, it just flicks but won’t load

    1. I think something has gone wrong. Which option did you use to install iOS 4.3.1 in itunes, upgrade or restore?? Restore iOS 4.3.1 again and try Redsn0w.

  12. OscarMike132says:

    I already have iOS 4.3.1 installed so do i skip step 2 and will my installed apps be deleted if i jailbreak?

    1. Yes, you can skip and already installed apps will also remain intact.

      1. Oscarmike132says:

        Thanks man. Everything went well.

  13. MICHAEL24STARsays:

    Works, but very buggy!
