Hacker and unc0ver lead developer Pwn20wnd appears to have been busy this weekend, revising the unc0ver v3.0.0 pre-release jailbreak tool at least five more times since Saturday afternoon. Betas 22-26 include the brand-new rootfs remount that surfaced yesterday afternoon compliments of hacker and software tinkerer @MiscMisty.
Pwn20wnd took to Twitter this morning to announce the bulk of those revisions and elucidate what they represent:
Citing the changelog published on Pwn20wnd’s GitHub
repository, this morning’s multitude of revisions encompass the ensuing
changes:
02/10/2019 – v3.0.0~b22 was released for public testing with the following changes:
– Extend the partial iOS 12 support with root filesystem remount as R/W
– Enable disabling app revokes on iOS 12
02/10/2019 – v3.0.0~b23 was released for public testing with the following changes:
– Enable RootFS Restore on iOS 12
02/10/2019 – v3.0.0~b24 was released for public testing with the following changes:
– 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
02/10/2019 – v3.0.0~b25 was released for public testing with the following changes:
– Add more debugging to the root filesystem remount
– Clean up some logic for log window pipes
02/10/2019 – v3.0.0~b26 was released for public testing with the following changes:
– Clean up the root filesystem remount
The new rootfs remount support is an extension of the original ‘partial’ support that was added for iOS 12 almost a week ago. Because of the exploit used, this partial support only works on 16K devices including A8X through A12 (A8X and A12 are temporarily excluded, but everything in between is supported). Notably, this ‘partial’ iOS 12 support doesn’t install Cydia, so users would instead use SSH to handle the bulk of their installations and actions.
The latest unc0ver v3.0.0 pre-release also adopts rootfs
restore support on iOS 12, a beefier means of preventing jailbreak detection, and
some important cleanup to help streamline the tool given all the recent
changes.
Despite the latest enhancements, the unc0ver v3.0.0 pre-release is a beta and should be treated as such. Unless you’re an experienced jailbreaker or developer and understand how to troubleshoot likely bugs, you’re best off waiting until unc0ver v3.0.0 comes out of its pre-release stages and is officially released to the public.
At
the time of this writing, the latest official public release of the unc0ver
jailbreak tool is v2.2.6. Both versions can be downloaded from Pwn20wnd’s GitHub repository,
although it’s worth noting that only the unc0ver v3.0.0 pre-release supports
iOS 11.4.x.
