Pwn20wnd initially launched the pre-release of unc0ver v2.1.0 for public testing almost a week ago, and as it would seem, the hacker has been somewhat busy refining the tool ahead of the upcoming official public launch.

Citing Pwn20wnd’s official GitHub repository, the unc0ver v2.1.0 pre-release has seen revisions on at least three separate occasions since our original story, with the latest change taking place just yesterday.

Curious as to what’s new in those revisions? We’ll outline everything for you below:

12/16/2018 – v2.1.0 was updated again for public testing with the following changes:

– Fix a bug in switching from Electra without restoring RootFS

12/17/2018 – v2.1.0 was updated again for public testing with the following changes:

– Update “No Tweaks” mode to support new “Disable Loader” option in Cydia Substrate

– Added the ability to completely disable jailbreakd when Substrate is installed via a future Cydia update.

– Add internal support for completely disabling jailbreakd with a Resources update

12/19/2018 – v2.1.0 was updated again for public testing with the following changes:

– Make a special alert for the exploit error to make it more clear

– Automatically reboot when the user taps “OK” on the exploit error

– Improve the version checker

– Fix a really weird bug in the system that would stop Cydia Substrate from loading tweaks although this bug isn’t caused by the tool

– Make the UI support different font sizes or styles (E.g. Bold Text)

– Add the initial localization support (No localizations included yet)

– Reduce the number of stages

– Fix a bug in installing OpenSSH

As of this writing, unc0ver v2.1.0 is still in its pre-release stages and should be considered a beta. It’s only recommended for advanced users who understand the necessary troubleshooting steps when things go awry; everyone else should wait for the official release in the future, as pre-releases often contain experimental features and bugs.

If you aren’t comfortable using an unc0ver pre-release, then use the latest official release (v2.0.2) instead – it can be downloaded from Pwn20wnd’s official GitHub repository, and it incorporates support for Saurik’s recent Cydia Substrate update for iOS 11.

Unc0ver is a semi-tethered jailbreak just like Electra, which means you need to re-run the tool after every reboot. That aside, it bundles a newer Saurik-approved version of Cydia that runs better on iOS 11 right out of the box.

If you’ve never used unc0ver before, and plan to do so now, then you can follow our in-depth tutorial about how to install and run the unc0ver jailbreak. The unc0ver jailbreak tool supports all devices that can run iOS 11.0-11.4 beta 3.
