I think that is just about how to strip the iodeOS modifications from the system without a complete reset or something. Probably using adb
and fastboot
as you mentioned. But I have no idea about how any of this works or why I would want to do that.
If you want to install any other OS, just go about it as you would normally. I don’t see how this changes anything really.
What are some other companies that are also very down to earth and not using every trick in the book to get away with stuff?
I come to think of the Proton foundation, but that’s just because I am a fanboy of theirs.
