Hacker andunc0verlead developerPwn20wndissued at least three more revisions to the unc0ver v2.2.0 pre-releasesince our last coverage, with each revision bringing fresh bug fixes and performance improvements to make thejailbreakexperience as smooth as possible for users.
Citing the changelog published on Pwn20wnd’s officialGitHubpage, those three revisions encompass the following changes:
07-08-2025 – v2.2.0~b6 was released for public testing with the following changes:
– Performance improvements
07-08-2025 – v2.2.0~b7 was released for public testing with the following changes:
– Makes experimental changes to the empty_list (VFS) exploit to improve the reliability of it (Credits to@GeoSn0wfor the tip)
03-07-2025 – v2.2.0~b8 was released for public testing with the following changes:
– Fix switching from Electra without restoring root filesystem
ATweetshared by Pwn20wnd shortly after releasing the seventh revision appears to ask Twitter if they’ve noticed any reliability differences in the VFS exploit since testing. On the other hand, there appear to be mixed results:
Notably, these revisions do not add support for@S0rryMyBad’s new iOS 12-centric kernel exploit. It seems more likely that this would be integrated in an entirely new version of unc0ver than in abetarevision.
As a reminder to developers, unc0ver v2.2.0 drops support for Substitute in place ofCydia Substrate, so Pwn20wnd recommends adjusting your jailbreak tweaks to meet this criteria:
As with all 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 thetroubleshootingsteps 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 toocan be downloaded from Pwn20wnd’s official GitHub repository.
Unc0ver is asemi-tetheredjailbreak just likeElectra, which means you must re-run the tool after every reboot. That aside, it bundles a neweriOS 11-optimized build ofCydiathat sports the official seal of approval fromSaurik.
If you don’t know how to use unc0ver, then you’re able to follow our in-depth tutorial abouthow 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 developerhere.
As Pwn20wnd’s bug report list grows thinner, we can only expect that a public release will ensue very soon. As always, we’ll keep you updated as this happens.
