Hacking Question should i update

Atmosphere I'm using and what's the deferent about burning fuses
If using Atmosphere, you are fine to update. You will need the latest version of Atmosphere and new sigpatches (your games will not work without updating sigpatches).

The fuses are an anti-downgrade measure from Nintendo. The Switch will burn a fuse whenever you update the firmware. It checks the firmware level when you boot and also the number of fuses that have been burned. It then compares this to how many fuses should have been burned at that firmware level. If not enough fuses are burned, it will burn the ones necessary. If too many fuses are burned, it will not boot. This prevents you from downgrading your firmware because the system will see that more fuses are burned than there should be at that particular firmware level. Custom firmware will bypass this fuse check, meaning that you will not burn fuses and you can still boot with the incorrect number of burned fuses.

As of now, there is no reason to downgrade your firmware. The vast majority of users would be fine just updating the official way and burning their fuses, saving them a lot of headache. However, most people on here, myself included, don't like the idea of something irreversible happening to our systems. Thus we update by downloading the firmware on a PC, moving it to the SD card, and installing it via choidujournx (homebrew). Using this method doesn't remove autoRCM the way that the official update method would (which means your fuses will not be burned).
