Jailbreak iOS 5.0.1 with Redsn0w 0.9.9b9

Update: An untethered version is now available, here is our guide: How to jailbreak iOS 5.0.1 untethered with redsn0w.

Redsn0w 0.9.9b9 isn’t the first jailbreak for iOS 5.0,1, but it’s certainly much easier to use thanks to native 5.0.1 support. This basically means you don’t have to point it at older firmware to perform the jailbreak, but it does still require a tether boot.


  • iOS 5.0.1 installed
  • iPhone 4, iPhone 3GS, iPad 1, or iPod touch 3rd & 4th generations

If you already have iOS 5.01 installed you do not need to download any IPSW files.

Jailbreaking iOS 5.0.1 using Redsn0w 0.9.9b9

These instructions are the same for all compatible iOS devices and from running redsnow in Mac OS X or Windows:

  1. Download redsn0w 0.9.9b9d: Mac OS X or Windows
  2. Launch Redsn0w and click on “Jailbreak”
  3. Put the iOS device into DFU mode by holding down the power button for 3 seconds, then start holding the Home button as well for an additional 10 seconds, then release the Power button but continue to hold the Home button for another 15 seconds
  4. Wait while the jailbreak is installed, this will take a few minutes. When finished you will see a “Tethered Jailbreak” popup window reminding you of the tethered status and the iPhone screen will no longer display gibberish text
  5. Still in Redsn0w, click back to the first screen and click on the “Extras” button
  6. Click on “Just Boot” and put the device back into DFU mode again the same way as before, or follow on screen, then let the iOS device boot tethered

Your iOS device will now boot jailbroken and is free to use Cydia.

Remember that if the battery dies or if you reboot the device manually, you’ll need to perform the tethered boot with redsn0w assistance again. This is the difference between a tethered vs untethered jailbreak and why people prefer untether solutions, the untether is in the works for iOS 5 but not yet available to the public. We’ll keep you posted when we learn more.

Update: Links to redsn0w 0.9.9b9d have been updated.

Update 2: You can now untether existing iOS 5.0.1 jailbreaks with Corona

Update 3: Redsn0w 0.9.10b1 is an untethered jailbreak now available, here is how to use it

  12. Cynthia says:

    When I follow the steps it says: Unrecognized build.
    Please check whether you have the latest version of redsn0w and whether this IOS version is supported yet.

  29. Don says:

    Ok I have a Verizon iPhone 4 5.0.1 and I followed the steps and it took a long time making my build. Before it was done the phone automatically turned its self back on before it was done. Well I let it be to see if it was supposed to do that then the redsnow asked to download cydia and I did and now it’s waiting for reboot and my phone was already on and wouldn’t do anything. So without canceling I put the phone back into dfu mode and I’m still waiting and it won’t do a thing.

    • Idjits says:

      Do you understand what a tethered boot is? It means every time you reboot the device it has to be booted tethered. Read the instructions.

  48. packit says:

    can’t install a thing from Cydia :( It says “Cannot Locate Package”…there are packages installed though. Usually I didn’t have to do any package installing. Anybody good at this?

  49. Paul says:

    Got a problem. I followed the steps to the T and reached the point with the famous pineapple everyone has been going on about. However, when I open Cydia, I am presented with the following error:

    UNABLE TO LOAD (The certificate for this server is invalid. You might be connecting to a server that is pretending to be “cydia.saurik.com” which could put your confidential information at risk.)

    Could this be an issue with the local wifi settings/proxy servers/ISPs, or is it more likely that there was an error in installing the jailbreak software? Has anyone else had this error and/or found a fix?

    I’ve gotten the JB to work, but for some reason cydia doesnt seem to have any packages listed under any of the sources, nor is it able to find things like openssh, mywi, etc. Not 100% sure whats going on here.

  52. Cudi says:

    Worked perfectly fine on my iPod touch 4G iOS 5.0.1!

    Make sure your iPod/iPhone is turned off when you enter DFU mode.
    If it doesn’t work, you just dont have the “magic touch”.

    • Nan says:

      Did you click the “Install Cydia” checkbox when jailbreaking with Redsn0w? Make sure that’s installed, then make sure after you have jailbroken with redsn0w, you then run redsn0w again for the tethered boot to enable Cydia.
