Just recently, the Dev Team released beta 3 of RedSn0w for Mac and Windows. This new update fixes an error that causes MobileSubstrate to sometimes crash on jailbroken devices. This error apparently only happened when RedSn0w was running over an existing jailbreak.

You can download the latest RedSn0w from our downloads page.

Dev Teams’ blog

Update #3: The b3 version of redsn0w fixes a problem where re-running redsn0w over an existing jailbreak would cause MobileSubstrate-based apps to stop running until MS was installed again.  Now you can re-run the redsn0w jailbreak step without worrying about that (but still remember to de-select the “Install Cydia” option if it’s already installed).

TIP: If auto-detection fails and redsn0w tells you no identifying data was found, you can always pre-select theappropriate 5.0.1 IPSW using “Extras->Select IPSW”.

    Is this for the untethered jailbreak?

  • EddieLevit

    When I ran this new Redsnow over my exisiting tethered jailbreak, in the middle of the installation process with the white text/black background, I received this error: “6000ms giving up…” I waited 3-4 minutes and then my ipod was stuck at the Apple logo, so I had to”just boot tethered” to get to the home screen. How can I get the new Redsnow to work properly without this error popping up? Thank you.

      @EddieLevit you dont redo the jailbreak. whats your version?

      • EddieLevit

        @brya123 I have 5.0.1, the latest version and it is tethered right now, but I want it untethered by using redsnow b3(latest version) to do so. How can I?

        • brya123

          @EddieLevit You got two choices 1. Open cydia search corona and dowload 2. (If that doesnt work) restore re-jailbreak

  • rigs101

    Do I have to restore with iTunes first..I’m already on 5.0.1 untethered can I run this program over my jailbreak?

    • brya123

      @rigs101 Dude there should be an update in your cydia for mobile substrate no restoring no rejailbreaking

      • rigs101

        @brya123 it’s updated already… How can I get backgrounder to work it makes my springboard crash all the time after I install it

        • brya123

          @rigs101 im not sure about background i have never used it but if your having a problem you (might) be able to fix it by restore and re-jailbreaking

        • rigs101

          @brya123 thanks I fixed it already I had to manually install the dev file it working fine now

    • jetalley123

      @rigs101 Yes but if you do a Backup first, it will restore all settings as well. Then Jailbreak with no problems! I did it yesterday and not have to change a thing. Just had to reinstall Cydia apps.

    what do i do if itunes wont let me update to 5.0? i still have the 4.3.3 jailbreak for the iphone 4. if know please help or send me links. thanks

    • brya123

      @darth109 you have to restore your iphone before doing any updates or your iphone could be fucked (stuck on apple logo) and would have to be taken to apple to get fixed

  • ash112233

    • brya123

      @ShamsTajulIslam i would say it could be jailbreak bugs or its just your iphone

  • Calvnhob

    Hey guys, Is anyone else having problems using Fivelrows?

    I have an IPhone 4, version 5.0.1 using Redsn0w 0.9.10b3. I’ve installed Fivelrows at least 10 different times. Respringed each time, but nothing happens. It’s installed but it’s just not working.

    Does anyone have any idea whats wrong? I’ve used Fivelrows before on this same phone. Never had a problem before.

  • Iam_Raw_Swag

    so i must be using the right ipsw or it will be a tethered jailbreak
