How to do an untethered jailbreak on iOS 5.0.1 (up to A4)[UPDATE:New Download Links!]

Being a technical wizard at my school I am always asked how to jailbreak devices and the benefits of it. So I am going to start adding some jailbreaking goodness to the site. Anyways today I am going to walk you through jailbreaking your iOS 5.0.1 device. There will be a video for you to watch on how to do it below and remember this can be done for Mac and PC users. So let’s get started.

1. Download the newest version of redsn0w UPDATE: (9.10b5) (mac) (windows) and iOS 5.0.1.
2. Open up redsn0w and you will be welcomed by the following screen (click to enlarge):

3. From the welcome screen hit extras->select ISPW and find your iOS 5.0.1 download.

4. You will see a prompt saying that this will be used for the rest of the session. Select ok. From the screen hit back to get to the main screen from number 2. Then hit jailbreak

5. Just select jailbreak for now and hit next. (Multitasking gestures don’t work on the iPhone and should work on the iPad 1 with iOS 5.0.1)

6. Follow the on screen instructions and wait for reboot.

7.To get a reboot you will need to press back to get to the main screen when the Apple Logo appears on your phone. From there hit extras and then boot tethered. Follow the instructions and you should be fine. If this was done correctly you should see your iDevice booting with a pineapple

8. Enter cydia. Hit developer and then go to the search. From there search Corona. In the drop down menu it should say Corona 5.0.1 untethered. Select that and then install. You know have a fully jailbroken phone! If you did not get any of this watch the tutorial below!

Congrats!

The iPhone 4s untethered jailbreak has been achieved

The iPhone 4s has never had an untethered jailbreak. In fact there hasn’t really been any jailbreak for the iPhone 4s since we have first seen it about 2 months ago. Now there is going to be not only an iPhone 4s jailbreak but it will also be untethered. Even though they have cracked the problem for the A5 we won’t likely see this anytime soon so don’t get your hopes up. Most likely after Christmas. pod2G has cracked it and here is the official statement:

OK, figured it out, the A5 cache is not a problem anymore. I sorted it out by doing the untether in a single thread and by flushing all the dcache then all the icache in a row at a strategical point of the process. It took me like a hundred of tests to find the key. Hard for the nerves. For the tech guys, here is a link explaining issues related to self modifying code ( or code patching ) on the ARM platform : http://blogs.arm.com/software-enablement/141-caches-and-self-modifying-code/

Another news : I discussed with @saurik today about the launchd boot process, and he’s found one missing piece of the puzzle I needed to have a perfectly stable jailbreak. He’s definitly one of the best iOS gurus out there. Thank you saurik!

Good work guys. I can’t wait to see the tool for this.

4.3.4/4.2.9 kills untethered jailbreak

20110717-011850.jpg

It seems that jailbreak.me wasn’t the only jailbreak tool killed in 4.3.4/4.2.9 but the untethered jailbreak used from 4.1 was also closed. The 4.3.4 update was pushed really quickly to fix the security hole allowing a jailbreak on the device through a PDF vulnerability. Apple usually posts updates like that very quickly to make sure that their users aren’t at risk. This is a question of if this was patched to security concern or if this is another attempt to make jail breaking even harder so less people do it. Thanks To The Jailbreak Community for devoting time so we can have an easy jailbreak solution.
