Hacker and unc0ver lead developer Pwn20wnd released unc0ver v2.2.6 to the masses this week with bootstrap extraction and Cydia installation-related bug fixes and pushed two more revisions to the unc0ver v3.0.0 pre-release with a bevy of other bug fixes and enhancements.

The changelog published on Pwn20wnd’s GitHub repository cites
the following changes present in the unc0ver v2.2.6 public release:

02/05/2019 – v2.2.6 was released for production with the following changes:

– Fix a bug in extracting bootstrap / installing Cydia

If you’re using unc0ver v2.2.5 or earlier, then you’re advised
to download and install unc0ver v2.2.6 at your earliest convenience to ensure that
you’re taking advantage of all the latest jailbreak-related patches and

As always, you can download the unc0ver v2.2.6 public release from Pwn20wnd’s official GitHub repository; it supports iOS 11.0-11.4 beta 3.

In addition to uploading an updated public release, Pwn20wnd also revised the unc0ver v3.0.0 pre-release at least two more times since our last coverage. Beta 16 and beta 17 bring the following changes to the tool respectively:

02/05/2019 – v3.0.0~b16 was released for public testing with the following changes:

– Fix a bug in log window

– Fix a bug in logging

– Add more debugging to RootFS remount

02/05/2019 – v3.0.0~b17 was released for public testing with the following changes:

– Fix a bug in extracting bootstrap / installing Cydia

The unc0ver v3.0.0 pre-release is still in beta beta stages,
which means it shouldn’t’ be deployed on just any device. This beta is intended
for advanced users and jailbreak developers who possess a basic knowledge of error troubleshooting, as bugs tend
to transpire during beta testing periods.

unc0ver v3.0.0 pre-release is the only version of this jailbreak tool that
supports iOS 11.4-11.4.1, but only on certain devices (A9/A9X/A10/A10X/A11). It
will install Cydia and supports Cydia Substrate on these firmware versions.

unc0ver v3.0.0 pre-release also sports partial support for iOS 12.0-12.1.2 on
certain devices (a limitation of the exploit used), but Cydia and Cydia Substrate are not yet fully compatible, and
so they will not be installed. SSH will be used instead. Those seeking a
full-featured iOS 12 jailbreak are advised to continue waiting.

If you’re still interested in downloading the unc0ver v3.0.0 pre-release, then you can get it from Pwn20wnd’s official GitHub repository. Nevertheless, we continue to advise that novice jailbreakers use unc0ver v2.2.6 instead and continue waiting for official iOS 11.4-12.1.2 support.
