this is a work in progress next-gen version of checkra1n. it will take a while for it to be public, but it’s a pre-boot execution environment with a custom USB stack based off @_bazad’s ktrw. Goal is to allow loading of custom kernel extensions as well as kernels.
(Note that while it says 0.9.5.1, this diverges significantly from the actual checkra1n codebase and won’t be published until it actually works – the next few checkra1n updates won’t make use of this)
Q: What could loading custom kernel extensions allow you to do?
A: consider being able to have jailbreaks bundled as kext and automatically loading the right one based on version
