Citing the changelog published on Pwn20wnd’s official GitHub page, what is now the fifth pre-release beta of this particular unc0ver jailbreak tool version comprises of the following changes:
01/22/2019 – v2.2.0~b5 was released for public testing with the following changes:
– Fix theoretical bugs
– Improve assertion to make it safer
– Fix a bug in logging
– Update bootstrap
– Enable overwriting files in the bootstrap extractor
Just like the pre-release revisions that we reported about yesterday, this revision is still a beta and should not be deployed on daily driver handsets. This release is only intended for experienced jailbreakers or developers with knowledge of the troubleshooting steps required to handle potential bugs and instabilities.
Given how long the unc0ver v2.2.0 pre-release has been in its beta stages thus far, we expect that an official public release will follow in the coming days; of course, only time will tell.
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.
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. If you run into any problems while using unc0ver, then you can report bugs here.
