How the Nintendo Switch prevents downgrades by irreparably blowing its own fuses

While this is true, I was essentially saying that you don't have to remain on an older firmware as long as you're careful about how you move around between versions. I'm on 10.0 but I could go back to 3.1.0 anytime, and then move somewhere in between those versions if we got a coldboot exploit for example (which according to notable members of the Switch homebrew community is not likely).

Yeah, sure, you can ignore the fuses, but only if you assist the boot process using a jig and an injected payload. The stock Horizon kernel from FW 10.3 won't boot if your fuseset is for 3.1.0, unless you inject a chainloader which fakes the fuseset or removes the check.

Edit: I see what you were referring to, I was unspecific in my comment, updated it!
