It will be quite similar to the older versions of Checkra1n.Because the root folder would be inaccessible during a jailbreak, this volume would effectively become the new rootFS.

Rather than going rootless, the checkra1n team would try to get around Apple’s SSV security mechanism by creating a new volume for everything that can’t be bind mounted. On iOS & iPadOS 15, checkra1n could try to use bind mounts instead of union mounts, since union mounts are essentially obsolete and Secure Shell (SSH) access has already been sorted out for latest operating systems. The jailbreak experts said checkra1n will be going rootless as a solution sometime back. Therefore, a lot of work is required to go through the new security mitigation.

We are all aware of Apple’s signed system volume (SSV) security mechanism introduced with iOS 15. Hence Checkm8 exploit can not be patchable via software update it must work on every iOS version including iOS 15. How will be iOS 15 Checkra1n jailbreakĬheckra1n team is still working on adding iOS 15 semi-tethered jailbreak support for Checkra1n. Cydia will appear on your homescreen after a few seconds.
