: iOS 15 introduced a "sealed" root file system, forcing developers to transition to rootless jailbreaks . This means modifications are restricted to certain directories, which changed how many traditional tweaks functioned.
: Later in 2022, the XinaA15 tool emerged as a public jailbreak for modern "rootless" environments, supporting A12–A15 devices (like iPhone 13) running iOS 15.0 to 15.1.1. Significant Challenges
: At launch, the tool focused on iOS 15.0 through iOS 15.1.1 . The developers later worked toward expanding support for versions up to iOS 15.4.1 .
: While older devices (iPhone X and earlier) remained vulnerable via hardware-level exploits like checkm8 , newer A12+ chips required entirely new software-based kernel vulnerabilities. Why Users Jailbreak iOS 15
In 2022, the jailbreaking community reached a significant milestone with the development of the , overcoming major internal changes Apple implemented to make the process more difficult. Key Developments of 2022
: In July 2022, the Odyssey Team announced Cheyote (formerly Taurine15), the first major tool specifically designed for iOS 15.
