QiLin Jailbreak Toolkit – Code Base for iOS jailbreak development

As promised, Jonathan Levin aka Morpheus has released his QiLin Toolkit for developers. Here’s everything you need to know about it.

What is QiLin Toolkit?

QiLin Toolkit is a code base that standardizes all the routine tasks of iOS jailbreak development. It is developed by the renowned iOS security researcher, Jonathan Levin aka Morpheus.

It uses existing open source Proof-of-concept exploits such as Ian Beer’s async_wake and Siguza’s v0rtex exploit.

There’s no KPP bypass involved as it relies on Xerub’s KPPless technique.


Every tool must achieve the following tasks before it can work as a fully functional jailbreak –

  • Root access
  • Sandbox escape
  • Remount the root filesystem with R/W
  • Running binaries

With this utility, all the grunt work is done and you can even build a jailbreak in less than 10 lines of code!

In other words, QiLin Toolkit provides jailbreak developers the necessary coding environment for developing a jailbreak.

Since everything is already set up beforehand, a developer needs to write a lot less code as compared to the conventional approach.

How can I use it?

If you are not a developer, you shouldn’t even bother using it, of course.

It will go fully open-source in the near future and will be maintained by Morpheus. As of now, it is closed source. The developer is also accepting API requests on his website.


As far as I know, you can use it only to develop jailbreak tools for iOS 10 and 1,1 the reason being that Xerub’s KPPless approach is not backward compatible with iOS 9 firmware and below.

Remember, this is NOT a jailbreak and will not install Cydia on your iOS device.

Is it useful for end users?

Yes, it will surely streamline the jailbreak development process manifold. This means your device will get a better and cleaner jailbreak but that’s it.

It’s developers who will actually benefit the most from such a potent tool.

Moreover, power users and upcoming developers can utilize it to learn more about what goes on behind the scenes in a jailbreak.


It is still very new and I am sure the developers will utilize it to develop future jailbreak tools.
