Hacking Question Can someone explain EmuNAND to me?

thanks much for the answer..

Switch just will crash and that's it. Nothing will be damaged.

You will lose emunand and have to recreate one after fixing your sdcard. Also regqrding sdcards, it has been a moot whether using emunand shortens the sdcards life as using it will meqn a constant read&write to the partition used by the emunand. While the concept may hold true, many, including me, have used emunand for quite a long time and none of our sdcards broke yet.

yea yea was a theory you can use a fuse on the Mainboard too

If only there were people looking at the OS and comparing the changes, oh wait.

which changes?

which changes?

The changed that would cause a fuse to be written that would allow the emunand to ban the sysnand.

That depends, iirc, normally when an update fails the update would rollback to the previous firmware. But if it doesn't rollback then that would mean your emunand would be on a softbrick state. This would be easily fixable if we can also access maintenance mode on emunand (considering you're not banned), but if not then yes, you have to recreate emunand again.
