Only works on iOS 11.0 through iOS 11.1. Apple has stopped signing those versions so should anything go wrong, you can only upgrade to iOS 11.2 and that’s the end of the jailbreaking adventure.
LiberiOS is what is called a tethered jailbreak. That practically means that you need to perform the jailbreaking process every time you reboot your phone.
