If you’ve been following along with the progress on the Odyssey Team’s upcoming Cheyote jailbreak for iOS & iPadOS 15.0-15.1.1 recently, then you’d know that one of the major setbacks that’s delaying the launch is preparing jailbreak tweaks to support iOS & iPadOS 15 via the rootless dynamic and with libhooker as the primary means of tweak injection.
But despite the aforementioned challenges faced by the Odyssey Team, hacker Zhu Xinlang (@xina520) appears to be capturing a significant amount of attention Wednesday afternoon after publishing a video to YouTube that appears to demonstrate successful tweak injection on an iPhone running iOS 15.1.
In the video, the hacker is shown installing the YouTube Reborn jailbreak tweak via the Sileo package manager app and using it to perform privileged actions in the YouTube app that wouldn’t otherwise be possible in an installation of the app on a stock device.
But before you get too excited after seeing this, Xinlang warns in a Tweet that the execution “is not as perfect as it appears.” The hacked cites no shortage of compatibility issues that still need to be resolved, however they seem adamant about continuing efforts to finish the project while supporting “compatibility with some old components,” likely referring to older frameworks that aren’t libhooker.
Xinlang appears to be using libsubstrate for tweak injection in the demnstration video, which is different from full-fledged tweak injection methods regularly used by the big-brand jailbreaks such as libhooker and Substitute. This tweak injection method likely limits the types of jailbreak tweaks that can be used.
This isn’t the first video Xinlang has shared to YouTube, in fact, another video published back in June demonstrates that the hacker has been working on this project for more than just a couple of months. Despite this, there aren’t any signs that Xinlang plans to release this jailbreak when completed, so it’s merely to be taken as a proof of concept to show off what’s possible at this time.
