How to Jailbreak iOS 5.0.1 using Ac1dSn0w [Step by Step Guide]


Supported Devices (iOS5/iOS5.0.1):

  • iPhone 3Gs
  • iPhone 4 (GSM)
  • iPod Touch 4G
  • iPad 1

Here is a text and video guide on how to jailbreak iOS 5.0.1 using Ac1dSn0w.

Step 1: Download Ac1dSn0w from our downloads page and open it up.
Step 2: Put your device into DFU mode (If you don’t know how to do this, check the “show assistant” box in Ac1dSn0w and it will show you how to do it)
Step 3: Click Jailbreak.
Step 4: Once it has booted up, put your device back into DFU mode.
Step 5: Click “tethered boot”
Step 6: A white Cydia icon will appear shortly, don’t panic if you don’t see it immediately after booting.

Congratulations, your device is now jailbreak on iOS 5.0.1. Again, this is still a tethered jailbreak but this is much quicker and easier than RedSn0w in my opinion.

  • Hi just completed all these steps however, the Cydia icon still has not appeared, any ideas?

    • What device/firmware are you trying to jailbreak?

      • iPhone 3gs 5.0.1, still not coming up with Cydia

        • Have you tried to tether boot again? Also, try turning Wi-Fi off and re-jailbreaking; that has worked in some instances.

  • Poserboy2001

    Does the firmware make a difference?

    • Yes, you need iOS 5.0 or 5.0.1 for this jailbreak to work.

  • Kyle Miller

    Is this teatherd or unteathered

    • Tethered. Untethered should be here soon though.

  • Kris Wilson

    I used Ac1dSn0w on my iphone 4 (5.0.1) and the Cydia icon did install but when I click Cydia the icon flashes but never opens….Anyone have an idea whats gone wrong? I’ve tried jailbreaking 3 times.

    • CDMA or GSM? Did you boot tethered after running into the issue?

      • Kris Wilson

        I have a ATT 11.0 iPhone 4 Model MC319LL Version 5.0.1(9A405) Yes I did booted tethered after running into the issue.. Any ideas? can I txt you a screen shot so you can see Cydia icon is loaded but won’t open?

        • Then I’m not sure what your issue could be. I would suggest restoring the iPhone to factory settings.

          If it still doesn’t work after that, try using RedSn0w to jailbreak.

    Hi, thanks for your tutorial, I’m a newbie at Jailbreaking.
    I purchased a jailbroken 3GS iPhone and updated it to iOS5.1 not knowing that I would be locking it and rendering my SIM obsolete.
    I have followed your instructions and the phone never reboots after hitting the JB button. Ac1dsn0w shows that I’ve exited recovery mode, but the wheel on my iPhone just spins for about 5 minutes then it reboots back to the iOS5.1 set up screen. When I try to activate the phone it says “Only compatible SIM cards from a supported carrier may be used to activate…”
    Is there something I’m missing?
    Thanks in advance.
