Citing a couple of Tweets shared by Pwn20wnd not too long ago, unc0ver V1.0.3 apparently resolves a few issues known to occur on supported beta firmware versions and further improves the RootFS Restore feature:

Citing the official /r/jailbreak post, the new V1.0.3 release encompasses the following changes:

• Fix known issues with beta firmware supported by unc0ver

• Resolves the “Failed to copy over resources to RootFS” error message some users were receiving

All unc0ver jailbreak users are advised to download the latest version of unc0ver from Pwn20wnd’s official GitHub repository at their earliest convenience. Although the update mostly targets beta firmware users, refinements made in the tool’s code undoubtedly improve stability across the board.

Unc0ver is a semi-untethered jailbreak just like Electra, which means you need to re-run the tool after every reboot. That aside, it encompasses a newer Saurik-approved version of the Cydia Store that runs better on iOS 11.

You can follow our in-depth tutorial about how to install and run the unc0ver jailbreak.
