Jailbreaking iOS 5.0.1 is about as easy as it can get on both Mac and Windows, but Windows users might encounter a couple of hiccups along the way if you’re not careful.

The main thing to remember is that RedSn0w works best on Windows when you use XP Compatibility Mode and run it as an Administrator. By following those handy suggestions, the jailbreak process on Windows is just as easy as it is on the Mac.

Check inside for a video tutorial that shows how to perform an iOS 5.0.1 untethered jailbreak on a Windows 7 machine…

How to Jailbreak Untethered on Windows

Step 1: Download RedSn0w from our downloads page and right click and select Properties > Compatibility > select Windows XP Compatibility mode, then click OK.

Step 2: Right click on RedSn0w again and run as an Administrator.

Step 3: Put your iDevice into DFU mode, and click Jailbreak.

Step 4: Your device will now jailbreak, and afterwards you can run Cydia.

See? Easy as pie. For more information on RedSn0w, be sure to check out our dedicated RedSn0w page with more in-depth tutorials and explanations that showcase the inner workings of this great jailbreak tool.

Have you performed an untethered jailbreak on your iDevice yet? If so, let us know how the experience went.

    I’m on a 4.3.1 on my iphone 3Gs with the ipad baseband 06.15.00, I was wondering how I could update my iphone to 5.0.1 then jailbreak. I tried creating a custom IPSW on snowbreeze but it failed on itunes while installing. Any help is greatly appreciated. Thanks

      did u put the 3gs in pwn dfu mode first?

      • Anonymous

        also i think theres something to do with the bootrom whether its old or new because i was only able to make a custom 3gs ipsw for an old bootrom for a friend and it also kept failing when trying to restore on itunes. we just figured it was since he had a newer bootrom and didnt have shsh blobs saved

      • Patrick Cifuentes

        I followed the correct steps on the screen, now i am stuck on recovery mode.

    • I have the same problem. redsn0w says “waiting for reboot” and my phone reboots normally and the jailbreak doesn’t install.

        Has anyone resolved this issue? Keeps booting me out at “waiting to reboot” also. I’ve tried all combinations of things.

    Hey folks, just one quick question please:

    Is that the right order of things:

    1. I connect my iPhone to the PC
    2. Put it in DFU
    3. Hit Jailbreak

  • my GPS is not working after untether jb with redsnow. using iphone 4 5.0.1

    Please Help

  • successfully updated to this update. One problem though, i always have this error whenever i open iBooks saying that i should restore my iphone or download ibooks again.

    • It’s been doing that for a long time now..

  • This may have already been covered – I am currently Tethered Jailbroken, iPhone 4 iOS 5.0. Do I need to do a restore and then jailbreak from a brand new install of the firmware, or can I “Just Boot” or jailbreak over the current jailbreak using Redsn0w?
    Thanks 🙂
