Redns0w 0.9.10b5c: Untethered iOS 5.0.1 Jailbreak Updated to Fix Crashing Issue

Jailbreak iOS 5.0.1 Redsn0w

iPhone Dev team has released an updated version of Redns0w – Redsn0w 0.9.10b5c to fix some bugs.

Please note that Redsn0w and Corona iOS 5.0.1 Untether jailbreak supports iPhone 4, iPhone 3GS, iPad 1, iPod touch 4G, iPod touch 3G and Absinthe jailbreak and the Redsn0w CLI tool supports iPhone 4S and iPad 2. So this update is not meant for iPhone 4S and iPad 2 users.

iPhone Dev team has provided the following information on their blog about the latest version:

Version b5b fixes an issue with using custom ramdisks on iPhone3G and iPod2G, and version b5c prevents redsn0w from crashing due to the ever-growing ramdisk size :).
You can download Redsn0w 0.9.10b5c using this link for Mac and this link for Windows.
Update: You don’t need to rerun Redsn0w if you’ve already jailbroken your iOS device successfully.
 In case you need help in jailbreaking your iOS device, you can checkout our step by step guides to perform untethered jailbreak using Redsn0w, which have also been updated with the latest download links:

iPhone and iPad 2 users can check out our step-by-step guide to jailbreak using the Absinthe jailbreak released by the jailbreak dream team.

For Mac users:

For Windows users:

As always, let us know how it goes.

    • Edgar

  • joe

    • fas

      Never , yes NEVER.

      • zach

        i dont want to pay for it HELP!!!!!!!!

  • Stage 2

    None of the untethered builds have ever worked for me.
    About halfway through “uploading the second stage” my iphone 4(with 5.0.1) will just reboot.
    That’s it nothing ever happens. Anyone else?

    • duhh

      Try a different computer; when this happens to me I’ll try it twice to be sure and then switch to a different one, then all is good.

      • duhh

        Oh, and restore first to reduce the equation.

        • JO

          If you restore it will work fine ( dont resync until you jailbreak). Had the same problem

  • Nathan

    Do I just run this over the old jailbreak or is there something special I need to do

    • You don’t need to rerun Redsn0w if you’ve already jailbroken your iOS device.

        I’m a little confused by the “update” statement and yours as well. I would assume that everyone who downloaded the previous version of Redsnow successfully jailbroke their iphone. Why wouldn’t everyone need to download this latest version.

        If by “successful” you mean the phone never reboots, then I understand that. And actually, my phone does randomly reboot about once per day.

        So should I use this update?

        • The latest version fixes issue with the jailbreak process rather than improving the stability of a successfully jailbroken iOS device, which is the reason you don’t need to rerun Redsn0w.

          This update is for those users who had problems successfully jailbreaking their OS device due to the bugs in the jailbreaking process.

          Hope it clarifies.

          • train21reb

            Clear as mud….I guess.

            So even if I have some issues with random rebooting of my phone, this update won’t correct that?

        • Unlikely

      • kbatrph

        i have an iPhone 4s, jailbroken by Absinthe on Mac. Had been running pretty smoothly, but as of late, am getting A LOT of Springboard “crashes” and lockups, requiring rebooting the phone…..also having issues with pictures in the phone contacts not matching up correctly…currently running the G.O.C. HD theme….any help would be appreciated.

  • duhh

    So, we’re currently going to continue to let the iPhone 4s crash??

  • EJessie

    Do I just run this over the old jailbreak?

    • No, you don’t need to rerun Redsn0w if you’ve already jailbroken your iOS device.

      • Lolly

        Can u be more specific on I have dine jailbreak and it is 4.3.3..if I update to 5.0.1 due ihave to jailbreak using red snow

      • Lolly

        Can u be more specific on I have dine jailbreak and it is 4.3.3..if I update to 5.0.1 due ihave to jailbreak using red snow please reply me back

    • Toony

      The problem is probably coming from a recent install through cydia that might be buggy. Uninstall last few items that you got from cydia then install them again one at a time, testing your phone each time. If the problem reoccurs then it is likely to be whichever item you installed last, so just remove again and dont use until perhaps it has had an update to fix the issue. Works for me everytime i have a buggy cydia install. Good luck!!

  • Kay

    *And, if u r facing any problem with the current os jailbreak, u can restore back n trying it out with this new version…?

    • This update fixes bugs in the jailbreak process, it does not improve the stability of the jailbreak. So you can definitely try, but there is no guarantee this update fixes the issue you’re facing.

      • train21reb

        Ah, that’s much clearer than your original reply to me.

        Must just need another cup of coffee.

  • Frank

    If ur phone is real buggy can’t see why u shouldn’t restore to factory setting then jailbreak again… I downloaded an app that wasn’t ready for ios5 caused me many headaches make sure the apps are compatable even if u paid for them before check before u load them

  • PasserBy

    I found 100% of my crashes related to a tweak I installed.
    Best way to troubleshoot this is to disable mobile substrates that were recently installed with a tweak. This is the only true way of disabling a tweak without uninstalling it: turning it off in settings (if available) isn’t good enough.

    Mobile Substrates enabling/disabling can be found in SBSettings (more section) or Sprintomize 2 – both work well for me.

    Good luck!

  • Alluuuz

    I have a problem with my itunes. Every single time when im trying to synchronize my music into my jailbroke iphone 4 it deletes all my jailbroken games. What can i do differently? Please help me!

  • Ahmad

    Yes yes

  • Ryan

    So this update will make it so it won’t crash an keep making my phone go into safe mode all the time when I am doing things with it or will it still do this problem?

  • I bought an Iphone 4s from a friend of mine and apparently he had found it on the streets.
    I have restored all the system using the iTunes after that i setted all the configurations needed but now that i have done all these operations i can not make phone calls, basicaly the network bars do not appear on the left top of my screen.
    I am still able to use the Wireless connections but not the phone, I was wondering if the device has been blocked if so, is there any way of unblocking?
    Does the jailbreak will help in this situation?
    What procedures should I take to tackle this issue?
    I would really appreciate if someone could help with some piece of advice…
    Thanks a lot

  • Ice

    i am having Iphone 4 version 5.0.1 i recently jail broke it with Redsn0w 0.9.10b5c but it does not seem to resolve the issue of Cydia crashing, it crashes 80% of the time i try to open… and last night it acted weird as my iphone switched off itself and it never got on the apple logo disappears and again reappears as if it tries to switch it on but never gets on… so i jialbroke it again today with the same file… do any one else is also facing the same issue, is their any solution to it???

  • Kieran

    I have jailbroken my 3gs to version 5.0.1 by redsn0w. And the iphone runs quite slow at times and the main problem is that once or twice a day.. The carrier and WiFi will automatically turn itself off and then come back on around 5 seconds later.. And that repeats for about 2 mins… Any suggestions?? I have installed ultrasn0w but still got the problem.
