Hacker and unc0ver lead developer Pwn20wnd has been rather busy as late. In addition to revising the unc0ver v2.2.0 pre-release at least three times since our last writeup, he also pushed a new public build – v2.1.4 – with some notable improvements.

Pwn20wnd announced the update via Twitter on Saturday:

Citing the changelog posted on Pwn20wnd’s official GitHub repository, the new v2.1.4 public release encompasses the following changes:

01/26/2019 – v2.1.4 was released for production with the following changes:

– Decrease the app’s size from 63MBs to 22MBs by optimizing assets

The primary motive behind this update appears to have been to reduce the size of the unc0ver app. Astonishingly, it’s now almost one-third of the size it was before the update. Despite the size difference, uncover continues to work exactly how it did before the update.

As for the three recent revisions to the unc0ver v2.2.0 pre-release, the official changelog notes how they incorporate the following changes:

01/25/2019 – v2.2.0~b10 was released for public testing with the following changes:

– Fix RootFS Restore on certain devices

01/25/2019 – v2.2.0~b11 was released for public testing with the following changes:

– Add a switch to hide the log window

01/25/2019 – v2.2.0~b12 was released for public testing with the following changes:

– Decrease the app’s size from 81MBs to 25MBs by optimizing assets

At the time of this writing, unc0ver v2.1.4 is the latest public release available and is recommended for all users. If you’re using an earlier version of unc0ver already, then you can simply sideload the newer unc0ver app with Cydia Impactor over a USB connection to your computer and re-run the tool to take advantage of the latest improvements.

The unc0ver v2.2.0 pre-release, on the other hand, is a beta and is only intended for public testers. Unless you’re an experienced jailbreaker with a basic understanding of troubleshooting steps, you shouldn’t deploy unc0ver v2.2.0 until it’s officially released to the masses; instead, you’re advised to install unc0ver v2.1.4 in the interim.

Both versions of unc0ver (the v2.1.4 public release and the v2.2.0 pre-release) can be had from Pwn20wnd’s official GitHub repository. As always, we’ll keep you updated when v2.2.0 comes out of its pre-release stages.

Unc0ver is a semi-tethered jailbreak just like Electra, which means you must re-run the tool after every reboot. That aside, it bundles a newer iOS 11-optimized build of Cydia that sports the official seal of approval from Saurik.

If you don’t know how to use unc0ver, then you can follow our in-depth tutorial about how to install and run the unc0ver jailbreak. The unc0ver jailbreak supports all devices that run iOS 11.0-11.4 beta 3. Should you run into any problems while using unc0ver, you can report bugs to the developer here.
