LiberiOS

LiberiOS is a semi-untethered jailbreak for devices running iOS 11.0 - 11.1.2. It was released on 2017, just one day after the tvOS 11 jailbreak LiberTV. This jailbreak, like its sibling, makes use of his QiLin Toolkit.

The very first version of the jailbreak included Cydia for the purposes of SHSH blob saving only, because saurik had yet to update it for iOS 11. On 2018, Jonathan stated he would never add Cydia support to LiberiOS, owing to derogatory remarks and false statements made by saurik on reddit forums. Although a complete jailbreak, LiberiOS is classified as a "dev" or "pro" jailbreak, meant primarily for security researchers and less for the tweak-phile.

The jailbreak drops a complete set of Jonathan Levin's compiled binary utilities (from opensource.apple.com) into  (so as to negate any potential for conflict with existing binaries). Jonathan's own toolset is installed in. The user can either move the binaries from the shell environment to their respective locations, or use  to set up paths and drop into a ZSH environment which will make use of these paths, thereby leaving the root filesystem almost unaffected.

The jailbreak also disables auto updates by redirecting mesu.apple.com to 127.0.0.1. This has the side effect of making stock apps impossible to reinstall. That said, this is not a real issue since they can be installed prior to jailbreaking, or at any time the mesu.apple.com entry can be removed from /etc/hosts. Other App Store applications are unaffected.
