2017 ended with a surprise for jailbreak users, Google Project Zero specialist Ian Beer published details about vulnerabilities in iOS and macOS kernels, as well as the proof-of-concept exploit. This news was a big event for the jailbreak community, as the information provided promised the immediate availability of jailbreak tools for iOS 11. That’s exactly what happened.
LiberiOS Jailbreak for iOS 11/11.1.2
Jonathan Levin, OS internal, was the first to introduce the LiberiOS tool for jailbreak iOS 11 (up to iOS version 11.1.2). This solution will work on iPhone 5s, SE, 6, 6s, 6 Plus, 6s Plus, 7, 7 Plus, 8, 8 Plus, iPhone X, and also for 64-bit iPad and iPod of the sixth generation. In addition, LiberTV supports Apple TV 4 and Apple TV 4K, running under tvOS 11.0 (up to version tvOS 11.1.2).
Unfortunately, while it’s not an untethered jailbreak (tethered jailbreak), that means after each reboot or shutdown of the device it will have to be restored again. Another significant drawback is the lack of support for Cydia, because without the application directory, a jailbroken device is almost useless for an ordinary user.
Recently, Jay Freeman (@saurik) published a series of excuses in response to criticism, which has recently come from all sides. The Cydia developer confirmed that he is already working with the data published by Ian Beer, and Cydia will soon be working on iOS 11.
By the way, an interesting fact. Jonathan Levin said that he had repeatedly tried to contact Freeman and join forces, but for some reason never received any response. As a result, Levin commented on the situation to RedmondPie, openly criticizing the work of Cydia and indirectly the developer.
