Jailbreak iOS 5 & iOS 5.0.1 Tethered on iPhone, iPad & iPod Touch Using Ac1dsn0w [How-to Guide]

It sure is a busy day today within the jailbreak community. There have been tons of news concerning the jailbreak community thrown our way. One of the most prominent news that was brought into our attention today is the release of a new jailbreak tool called Ac1dsn0w by the Pwn Dev Team. Aside from the new interface, as of now this jailbreak tool doesn't bring something new to the table but it promises a few new features for future updates. Today we are going to provide a tutorial on how to jailbreak iOS 5 and iOS 5.0.1 using Ac1dsn0w Beta 1.

NOTE: iPhone Dev Team frontman MuscleNerd has confirmed that this jailbreak tool on its current form contains some codes that are deemed to infringe copyright laws. So we will not be providing the download links for the tool due to legal reasons. We are only providing the tutorial for the sake of imparting information. So proceed at your own risk. And also keep in mind that this is a very early beta so it is bound to have bugs. If you want a more reliable jailbreak, use Redsn0w or Sn0wbreeze.

Steps on How to Jailbreak iOS 5 and iOS 5.0.1 Using Ac1dsn0w Beta 1:

    1. Download Ac1dsn0w for Mac and Open it.


  1. Connect your iPhone, iPad or iPod touch that's running iOS 5 or iOS 5.0.1 to your Mac.
  2. Turn OFF your iDevice.
  3. Click on Show Assistant, you should see an on-screen instructions on how to put your device to DFU Mode.
  4. Once your device has been placed into DFU Mode, click the Jailbreak button in Ac1dsn0w and the program will proceed to jailbreak your device.
  5. After the jailbreak process, your device should reboot.
  6. Now place your device into DFU Mode again. Click on the Tethered Boot button to complete the process.

And that's it. Take note that this is a TETHERED jailbreak which means that each time your device gets shut down or rebooted, you will need to connect your device to your Mac again and boot it into tethered more using Ac1dsn0w. Or if you want, you can convert your tethered jailbreak to a semi-tethered one by following this guide.

    Looks like there will be no untethereD jailbreak for ios 5
    It’s more than 2 month after release the ios 5 but there is no untethred jailbreak
    And hackers like ”i0n1c” say we can not jailbreak the ios 5 so …
    Me and many people who the have iphone (ios 5) have no hope for untethered.
    We just still wait for untethered…

      Noone has ever confirmed that you can’t JB on iOS 5. Infact Musclenerd has proven with screenshots that it has been already jailbroken but its just not yet ready for a prime time release. i0nic isn’t even working on a JB for iOS 5 for that matter of fact. Its the Chronic & iPhone Dev-Teams that you need to look upto for a JB. Hackers work hard to bring freedom on our jailed devices. So all we can do right now is to respect their efforts & hope for an early release. Afterall, we are getting this for free.

    How can i use redsnow to get iOS 5.0.1 without loosing my current bb, which is 4.10.01 ? Because when i try to use the original 5.0.1 file to create a costum firmware, redsnow tells me “unrecognized build” every time..

      Redsn0w cannot make / cook custom iOS 5.0.1 IPSWs yet. instead, use Sn0wbreeze v2.8b11 & create your custom iOS 5.0.1 IPSW with it. Later, use the same custom IPSW for your restore.

    it’s ok with Gevey sim?

      Pramod9 years, 11 months ago

      Use Redsn0w instead, just to be on the safer side. Also make sure that your not on any BB version higher than 04.11.xx because they aren’t Gevey compatible.
