But two people have upgrade and no fuse was blown. So I think I lean against them.Folks in the Reswitched Discord are saying 7.0.1->8.0.0 did burn a fuse.
Though I don't see this info reflected on Swithbrew yet.
@Sabishinbo
You can downgrade from 8.0.0 to 7.0.1, but if you burned a new fuse for 8.0.0, you'll need to boot with hekate or any other custom bootloader that ignores fuse checks.
Otherwise your switch will not boot.
