Saurik Gives A Progress Update On iOS 11 / 11.1.2 Jailbreak With Cydia Substrate Compatibility, More

Saurik, aka Jay Freeman, has confirmed that iOS 11 – 11.1.2 jailbreak with Cydia Installer and Substrate is coming, has also once again updated us on the progress of Cydia Substrate for both iOS 11.1.x.

The godfather of jailbreaking has provided a very lengthy statement on his work regarding the current state of Mobile Substrate and Cydia Substrate with iOS 11. Admitting that the jailbreak community has benefited from a plethora of activity which has resulted in a number of jailbreak tools being pushed out for consideration.

Cydia For iOS 11.1.2 Jailbreak

And yes, some of those jailbreaking tools offered for 32-bit devices running iOS 10.3.x, and some of which for 64-bit devices on the same firmware. Indeed, we had liberation of iOS 11 through to iOS 11.1.2, then, the fact they don’t come with Cydia and Substrate support because they both aren’t compatible with iOS 11 just yet.

The developer and hacker behind the jailbreak tweaks and IPA App Store have confirmed, is working on it with a well-known developer (CoolStar?) in the community to bring iOS 11 compatibility to Cydia and Substrate. But the developer later denied working with saurik, and now, this lengthy report was partially in reply to a CoolStar tweet. We can only suspect that there’s another well-known jailbreak developer assisting who will be credited when the project goes live in what saurik is calling a “surprise reveal.”

According to the extremely long post, which doesn’t actually give any real timescale on when this will be released but does confirm that he has been working hard with the unnamed developer to put something in place for iOS 11-11.1.2 jailbreak. It also confirms that he has taken a different direction to the “jailbread” route that CoolStar and others seem so excited about, claiming that the “architecture without ‘jailbreakd‘ is much cleaner.”

The architecture without the “jailbreakd” is much cleaner: it means that there isn’t some weird coordination boundary halfway between Substrate and the jailbreak; and the runtime stability will be a lot better: what people seem to want “jailbreakd” to do involves walking through data structures in the kernel–without the locks required to do that, and in a “slow” manner from userspace (increasing the likelihood of various race conditions)–every time processes spawn and Subtrate has to manage code injection.

Cydia

Jay says that he is “almost done” and that he has had to do most of the work himself as the talented individuals who otherwise work on exploit development have almost all left the scene. You can read this statement in full below:
