It Is Possible To Download iOS 9.2.1 Jailbreak For iPhone

If you want to know whether it is possible to download iOS 9.2.1 jailbreak for your iPhone then will find out it in this post together. Chinese hacker Min Zheng has posted a demo of Flying JB, a jailbreak tool for 32-bit devices running iOS 9.2.1 firmware version or lower. In the demo you can see how ‘Flying JB’ app successfully jailbreaking iPhone 5c running iOS 9.2.1. During the jailbreak process it also installs an unsigned Mobile Terminal app, that gives user the ability to run any command as root.


That all my may sound like great news at first and those who were waiting for iOS 9.2.1 jailbreak release date may feel happy, but the limitations and actual usage potential of Flying JB jailbrea tool are terribly limited.

Min Zheng explained that Flying JB is based off inpuTbag, this is 15 year old kernel HeapOverFlow vulnerability that Apple has fixed with iOS 9.3.2 release. The hacker also confirmed that the vulnerability was “very powerful” to exploit the iOS kernel before iOS 9.3.2. However, he added that to jailbreak iOS 9.3 and iOS 9.3.1 will be much harder.

The jailbreak only works on 32-bit devices, which means that it will work on iPhone 5 or lower running on iOS 9.2.1. It also seems like a work in progress as the sandbox escape isn’t public yet, so it is not a full jailbreak. So you won't be able to download iOS 9.2.1 jailbreak on your iPhone yet.


Unlike Pangu or TaiG jailbreak, Flying JB isn’t a GUI based tool, so jailbreaking your device wouldn’t be as simple as you used to if you have ever jailbroke you device. But if you’re adventurous enough, then you can go ahead and check out the source code on Github and follow the offered instructions to see if you can jailbreak your iOS 9.2.1device. But it is recommended to stay away from this process at this point of time.
