The pwn20wnd team has released a new beta of unc0ver 3.0 which comes with root filesystem remount for iOS 12. In simple words, that means there’s one less hurdle for developers to cross before they can get a fully working jailbreak for iOS 12.
Successfully remounted the root filesystem as R/W on iOS 12.1.1 ;).

Below is the full change-log of beta 22 and beta 23 release of unc0ver 3.0:
- Enable RootFS Restore on iOS 12
- Don’t update the kernel version string to make jailbreaking faster and third-party jailbreak detection harder
- Switch to a new technique for detecting the jailbroken state
- Enable the jailbroken state detection on iOS 12
Do note that unc0ver no longer bundles Substrate or Cydia due to compatibility issues.
While we have already seen the release of rootlessJB, an SSH-based developer focused jailbreak for iOS 12, a public jailbreak is yet to be released despite a few iOS 12 – iOS 12.1.2 exploits being detailed.
The major reason behind this is that developers still have two roadblocks to cross before they can develop a successful iOS 12 – iOS 12.1.2 jailbreak. One of them is getting root access to the filesystem and the second one is bypassing CoreTrust. Now that the first one has been achieved, it is likely that we will see developers find a way to bypass CoreTrust sooner than later now thereby leading the way to a public iOS 12 – iOS 12.1.2 jailbreak release.
