Jailbreak iOS 4.3.1 with Redsn0w 0.9.6rc9

Apr 3, 2011 - 64 Comments

jailbreak-ios-4-3-1-redsn0w Redsn0w 0.9.6rc9 is the first untethered iOS 4.3.1 jailbreak that is available for both Mac OS X and Windows. Redsn0w is one of the easier jailbreak tools to use, just follow the instructions and you will be jailbroken in a few minutes.

This guide will perform an untethered jailbreak with iOS 4.3.1 on iPhone 3GS, iPhone 4 GSM, iPod Touch 4G, iPod touch 3G, iPad, and Apple TV 2. Note that iPad 2 and iPhone 4 CDMA are not supported by this version of redsn0w. If you rely on ultrasn0w for an iPhone unlock, do not use this version of redsn0w.

How to Jailbreak iOS 4.3.1 using Redsn0w 0.9.6rc9

  1. Download iOS 4.3.1 IPSW and install it on your iOS device if you haven’t done so already
  2. Download Redsn0w 0.9.6rc9 (Windows & Mac OS X versions available)
  3. Launch Redsn0w and click on “Browse”
  4. Locate the iOS 4.3.1 IPSW file you downloaded in the first step and click “Open”
  5. Select “Next”
  6. Select the checkbox next to “Install Cydia” and click “Next”
  7. Make sure your iOS device is turned off and plugged into your computer and then click on “Next”
  8. Follow the on screen instructions to put your iOS device into DFU Mode: Hold down the Power button for 1 second, then continue to hold power while holding the Home button for 10 seconds, then release the power button but continue to hold the Home button for another 15 seconds.
  9. Once you are successfully in DFU mode, redsn0w will perform the jailbreak for you so let it do the work. Your iOS device will then restart automatically and you will be jailbroken

If you need to undo the jailbreak for any reason, it’s very simple, just restore your iOS device from within iTunes.

    I jailbroke my iPod touch 4g, and had to use run as admin. Try this aswell as the compatibility mode or one or the other. It jailbroke for me and worked flawlessly. The ONLY bug I see is photos doesn’t save images to the database correctly. The camera saved to the photo album and I can see the picture but when I click the trashcan to delete it just sits with a “saving image” message. Screenshots also don’t work for me. I tried restoring and rejailbreaking but same problem. I’ll try snowbreeze or the latest version of redsnow.

    If you get a white Cydia icon after jailbreaking, just redo the jailbreak process. You can run redsn0w over again, or you can restore the phone and do it from scratch.

    White Cydia just means it installed wrong, very easy to fix.

      This doesn’t even work, I tried it 3 times and it’s still a white icon :/

      • zofe says:

        make sure you have the right ios downloaded. for example i thought the ios4.3 was the same as ios 4.3.1… but apparently theres an ios 4.3 8f19 or something which i should have installed. my problem was that i used ios 4.3.1 with redsn0w on an iphone4 running ios4.3 8f19 and got the white cydia app. so go into your settings-about and check exactly which ios u have and google that. when redsn0w asks for the ios use the new one.

    This is for every one that had CRASH on RedSn0w iphone 4.3.1

    The solution is simple, run RedSn0w on compatibility mode XP and runa as administrator, this fixes the problem and runs perfect.

    Jailbreak with sn0wbreeze 2.5.1.

  17. will says:

    I was having the same problem, if you run it as windows xp compatibility and make sure the phone is in dfu mode before hand, I also click run as administrator incase that had anything to do with it, and its done jailbreaking now, im about to go back in for the ipad baseband fingers crossed.

  20. dan says:

    cydia does not work for me. It opens for a split second then closes

  21. James says:

    After I install the latest iOS (currently at 4.2.1) and JB.. Can I restore all my information (messages, apps, music, photos, contacts etc) from a previous backup to get them back, or will I have to reinstall everything from scratch?
    what about al my Cydia apps ? Will a restore bring those back as well, or am I back to square 1?

  22. Luke says:

    what if i already have a bunch of saved things with the redsn0w 4.2.1 jailbreak and if i do everything u say all my stuff still all be there????????????


    • Valashtar says:

      No. You’re out of luck with that, unfortunately.

      AptBackup will make a list of your installed packages and back that up and then restore them for you but you will lose all application data/settings.

    my 3gs got stuck on installing activation bundles and it end up in recovery mode so i kicked it out using tinyumbrella and now its stuck on emergency screen since i dont have an official sim so how to hacktivate?

  24. ROBERT says:

    hi i have been trying to jailbreak forever. i have downloaded the rquired files and when i get to the part where it sayd to “browse” for the ipsw i click desktop (where i saved it) yet it doesnt show up. its like its not even there. i can see the file on the desktop lol but like i said when i hit browse it shaows alot of other files on my desktop including redsnow but not the 4.3.1 file. NOONE can help me so far. any suggestions?

    p.s. i seem to remember trying to jailbreak with 4.2 software while i was on 4.3 and getting past this step so i dont know if that has anything to do with it. maybe a system restore?

    p.p.s this happens on my pc as well as my laptop.

    • Jeremy says:

      Robert, are you sure that the files are saving as .ipsw files? If you are not careful they can save as another file type (.zip) and won’t be viewed there. I hope this helps.

  25. Edwin says:

    I have an iphone 3gs running 4.2.1 with 5.15.04 baseband and 6.4 bootloader (I think 35th week of 2009). Can I untether jailbreak and unlock 4.2.1 with this version of redsn0w 0.9.6rc9 using the IPAD baseband?

    Is it advisable to do the IPAD baseband on 4.2.1 or too soon to do this?

    If anyone is still having problems with redsn0w crashing during ramdisk upload then remember to close itunes (as well as the XP compatibility mode) this solved the problem for me. Cheers

  33. Kudos to the man who figured out the ramdisk issue. Works perfectly when running in XP compatibility mode.

      Right-Click the program’s icon, and then click “properties”. Now open the “Compatibility” tab and check the box saying “Run this program in compatibility mode for:” and choose the system. Then click OK and….its done.

      I have xp service pack 3 how do I go back to service pack 2
      And why redsn0w doesn’t work in service pack 3?

  40. karmaghost says:

    For anybody who’s having trouble with redsn0w hanging on the “uploading ramdisk” part, try running redsn0w in XP compatibility mode. I’m using windows 7 and was having the same issue, but this solved it for me.

  41. Anton says:

    Now it’s frozen at ‘uploading ramdisk’ and my phone is saying ‘downloading jailbreak data..’

  42. Anton says:

    I’ve got the exact same problem, my iPhone first froze at the ramdisk part, and now it’s not even getting past the ‘exploiting the limera1n’ part

  43. Ky says:

    It hangs and close at uploading ramdisk ?help?
