acker and unc0ver lead developer Pwn20wnd pushed his ninth revision to the unc0ver v2.2.0 pre-release jailbreak tool for public testing on Friday. As you might come to expect, this revision incorporates minor bug fixes and improvements to help the beta process along.
We can gather from Pwn20wnd’s official GitHub changelog that this new revision brings the following changes:
01/25/2019 – v2.2.0~b9 was released for public testing with the following changes:
– Disable the experimental empty_list (VFS) exploit changes for now
– Fix certain error descriptions
In addition to these changes, a Tweet shared by Pwn20wnd this morning reveals that he’s aware of an issue that would cause ‘random reboots’ while jailbroken via unc0ver and is working on a fix:
Citing the comments from the Reddit thread linked in the Tweet, this fix will allegedly address random reboots during nightly charges, an issue I’ve personally experienced on my test device many times previously. Notably, this fix is not a part of the ninth unc0ver v2.2.0 pre-release revision, so we can expect another update in the future.
Much like the rest of the pre-release revisions that we’ve kept you in the loop of, these three are still betas and should not be deployed on all handsets. This release is only intended for experienced jailbreakers or developers with knowledge of the troubleshooting steps required to handle potential bugs and instabilities.
If you aren’t comfortable using a pre-release version of unc0ver, then we advise you to use the latest official public release (v2.1.3) instead; it too can be downloaded from Pwn20wnd’s official GitHub repository. As always, we’ll keep you updated when unc0ver 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.
