C0F3 Jailbreak for iOS 11-11.1.2 and iOS 10-10.3.3

Just like async_wake modifications, here’s yet another jailbreak tool for iOS 11 and 10. Here’s how you can download and install it on your iPhone, iPad, and iPod touch.

What is C0F3?

C0F3 is a jailbreak tool based on Ian Beer’s asyn_wake, Siguza’s v0rtex exploit, and Xerub’s KPPless jailbreak technique. It is developed by the C0F3 Dev Team.

Unlike other tools, it is compatible with both iOS 11 and 10 firmware. However, you will need to download different IPA file depending on your specific firmware version.

Jailbreak update

Here’s the complete list of developers involved in this project –

  • Joseph Shenton
  • Sem Voigtlander
  • Vincent Desmurs
  • Mason Shmadul
  • Jake James
  • Ben Mitchell (tester)

Warning – This jailbreak is still under development and I don’t recommend average users to install it just yet. It is meant to be used by developers and advanced users only, for now.

Moreover, it is untested with iOS 10 versions as of yet.

Is Cydia working?

As you already know, Cydia is still pending an update by Saurik. According to his latest comment, he is still working on Substrate but no substantial results have surfaced thus far.


Undoubtedly, Cydia will not work with this tool (for now) and you can’t install tweaks or add sources. However, Cydia icon and homepage will work like they should.



It is compatible with all 64-bit devices that are capable of running iOS 11 and 10 firmware versions. This means all devices up till iPhone X are supported, in theory.

Here’s what we know about the device compatibility of this tool so far –

  • Only iPhone X running iOS 11.1.2 is fully confirmed to work.
  • iPhone 6s has unresolved issues and will not work.
