Jake James released a jailbreak rootlessJB 3.0 for iOS 12.0-12.1.2

Talented hacker and software developer Jake James surprised the entire jailbreak community with the sudden release of rootlessJB 3.0.

This tool for jailbreaking devices with A9, A10 and A11 processors running iOS 12.0-12.1.2 does not support tweaks and is aimed at developers.

In a tweet-announcement, he also noted that there will be support for A12, but there is still a lot of work to be done on this. He will add support for the A7-A8 when a vulnerability is found.

Unlike the usual utilities like unc0ver orElectra, rootlessJB does not require remounting the filesystem to work. In addition, it does not need managers like Cydia or Sileo (accordingly, there is no support for tweaks either). Instead, an SSH connection is used for jailbreaking.

Although at the moment the tool of James does not support tweaks, this may change in one of the future versions.

Compatible devices

As of this writing, rootlessJB 3.0 is not compatible with iOS devices with A7, A8 and A12 processors. And if work on A12 and support will be added in one of the future updates, support for A7, A8 will only be released after the release of a suitable exploit. Jailbreak is currently available on:

  • Apple A9: iPhone 6s (Plus), iPhone SE, iPad (2017), iPad Pro 9.7″ and 12.9″ (2017)
  • Apple A10: iPhone 7 (Plus), iPad (2018)
  • Apple A10X: iPad Pro 10.5″, iPad Pro 12.9″ (2018)
  • Apple A11: iPhone 8 (Plus), iPhone X

Frankly, rootlessJB 3.0 is absolutely not intended for the average user, and unless you are a developer, you should wait for the standard jailbreak to be released. At the same time, it's interesting to see what happens when new exploits fall into the hands of talented programmers.
