More good news surfaced for the jailbreak community this weekend as hacker and iOS tinkerer Brandon Plank launched a new open source semi-untethered rootless jailbreak that supports all versions of iOS 12 dubbed RootlessJB4.
Rootless jailbreaks are essentially a category of jailbreak that avoid messing with the device’s root filesystem. As you might come to expect, this makes them more restrictive than their full-fledged jailbreak counterparts, such as checkra1n or unc0ver. On the other hand, rootless jailbreaks are, by nature, more difficult to detect by apps that implement jailbreak detection.
