Hacker and unc0ver jailbreak tool lead developer Pwn20wnd pushed the fifth revision to the unc0ver v2.1.1 pre-release this weekend with another handful of bug fixes and improvements.

Citing Pwn20wnd’s official GitHub page, this is the fifth revision to the unc0ver v.2.1.1 pre-release since its conception one week ago. The latest revision brings the changes listed below:

01/12/2019 – v2.1.1~b5 was released for public testing with the following changes:

– Fix Cydia reinstallation

– Fix OpenSSH (re-)installation

– Improve error messages

– Optimize the jailbreak

– Fix other trivial bugs

Like all pre-release iterations of the unc0ver jailbreak tool, we only recommend it to advanced users who have basic knowledge about jailbreak-centric troubleshooting. Everyone else should wait for the official release; pre-releases like this are basically betas and may contain experimental features and bugs.

If you aren’t comfortable using a pre-release version of unc0ver, then we advise you to use the latest official public release (v2.1.0) instead. The latter can also be downloaded from Pwn20wnd’s official GitHub repository.

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 himself.

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.
