Anthony Bouchard ∙ February 15, 2019

Renowned hacker and unc0ver lead developer Pwn20wnd has issued a new revision to the unc0ver v3.0.0 pre-release Friday morning; beta 28 is now the latest version available for public testing purposes.

In a Tweet shared just minutes ago by Pwn20wnd, we learn that unc0ver v3.0.0 beta 28 adds provisions for timstar’s iOS 12-centric v3ntex exploit; on the other hand, the tool only supports the iPad Air 2 and iPad mini 4 with the v3ntex exploit at the time of this writing. Support for more devices will come later:

Sam Bingner Teases functional Cydia app on iOS 12, but there’s still more work to be done

Anthony Bouchard ∙ February 12, 2019

A bevy of different iOS 12-centric kernel exploits have been released in the last several weeks, and while we don’t yet have a full-blown, Cydia-supported iOS 12 jailbreak, that’s not to say progress isn’t being made in producing one.

Jailbreak developer and unc0ver co-creator Sam Bingner shared a small teaser via Twitter on Tuesday of what appears to be a functional Cydia app running on iOS 12; but don’t be fooled, there’s still more work to be done:

Tihmstar releases v3ntex, a tfp0 exploit for iOS 12 devices

Matrix code hacked iPhone.

Just under two weeks ago, hacking guru tihmstar released v1ntex, a voucher_swap-like exploit for 4K devices that contributed to iOS 11.4.x support in both the Electra and unc0ver jailbreaks. But just this morning, tihmstar released another exploit dubbed v3ntex, which allegedly supports iOS 12 devices.

Tihmstar shared his exciting announcement via Twitter Monday morning with proof of the exploit, adding that he only tested his v3ntex exploit on an iPhone 6 running iOS 12.1.2 and that it could likely still do with some improvements:

Hacker and unc0ver lead developer Pwn20wnd dropped the 27th revision to the unc0ver v3.0.0 pre-release on Monday, and it's said to significantly improve the reliability of Brandon Azad’s voucher_swap exploit on supported iterations of iOS 12, including 12.0 through 12.1.2.

Pwn20wnd announced the revision via Twitter Monday morning, incorporating a link to the official GitHub repository where it can be downloaded:

Unc0ver v3.0.0 pre-release revised with rootfs remount support on iOS 12 & more

Anthony Bouchard ∙ February 10, 2019

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:

A rootfs remount is being released for iOS 12, raising hope for a normal iOS 12 jailbreak with Cydia

Anthony Bouchard ∙ February 9, 2019

Avid jailbreakers who are on iOS 12.0-12.1.2 currently have one of two options: 1) use rootlessJB 3.0, a developer-centric, SSH-based rootless jailbreak without Cydia; or 2) wait for a full-featured jailbreak solution with Cydia (like Electra or unc0ver) to surface. Fortunately, those who are stuck in the latter boat could be one step closer to jailbreaking as of this weekend.

Hackers @MiscMisty and @Lakr223 took to Twitter early Saturday morning to display a proof of concept of a working iOS 12.x-oriented rootfs remount. But perhaps more importantly, they noted how they would be releasing it very shortly.

Apple officially stops signing iOS 12.1.1 and 12.1.2, thwarting firmware downgrades via iTunes

Anthony Bouchard ∙ February 5, 2019

Following an exceptionally-long and unheard-of grace period, Apple has officially stopped signing both iOS 12.1.1 and 12.1.2 Tuesday evening, a move that packs some serious implications for the jailbreak community.

Update: iOS 12.1.1 beta 3 is apparently still being signed at the time of this writing. Downgrade immediately while you have the chance!

Apple first launched these firmware versions on December 5th and December 17th respectively, each to address small bug fixes and performance improvements in the operating system. But as we know, no software is entirely bug-proof.
