Odysseyra1n is a custom Procursus-based bootstrap for checkra1n devices that installs Sileo for package management and libhooker for tweak injection. Previously, Odysseyra1n needed to be installed via Terminal with a command line interface. But that changes starting today with the release of Betelguese.
Betelguese is, in essence, a macOS-supported one-click Odysseyra1n installer for all iPhones and iPads running iOS or iPadOS 12, 13, or 14 that have already been jailbroken with checkra1n.
