Pwn20wnd revises unc0ver v2.1.1 pre-release with bug fixes and improvements

After dropping the first unc0ver v2.1.1 pre-release earlier this week for public testing, hacker and lead developer Pwn20wnd issued a revised version of the unc0ver v2.1.1 pre-release Tuesday evening with more bug fixes and improvements.

Citing Pwn20wnd’s official GitHub page, this is now the third revision to the unc0ver v.2.1.1 pre-release since its conception. The latest update encompasses these changes:

01/08/2019 – v2.1.1~b3 was released for public testing with the following changes:

– Store kernel base in kernel_task->all_image_info_addr

– Store kernel slide in kernel_task->all_image_info_size

– Fix address assertion

– Fix snapshot mounting

Like all pre-releases, we can only recommend it to advanced users with basic knowledge about jailbreak-centric troubleshooting. Everyone else should wait for the official release, as pre-releases like this one are essentially betas and often contain experimental features and bug.

If you aren’t comfortable using a pre-release, then we advise you to use the latest official public release (v2.1.0) instead. The latter can 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.

We expect that the official unc0ver v.2.1.1 public release will come any day now, but it’s entirely possible that we’ll see more pre-releases in the meantime as Pwn20wnd further refines the jailbreak. Either way, it’s always nice to see this magnitude of dedication from a jailbreak tool developer.
