I've been making nand backups for every firmware revision but have always been doing raw dumps, is that actually necessary to save my ass in an emergency.

I'm in 6.1.0 now, and I've just created a backup of eMMC BOOT0/1 and eMMC SYS.

If I have to do a raw dump again I will, but curious if the above is enough to save me in an emergency I'm using hekate 4.2 btw

Boot0/1 and Sys should be enough, yes. Leaves you without your user partition, thus you will lose all installed software and savegames when restoring a bricked unit.
To be really on the safe side, I'd always do a raw backup.

on sx os it says it can backup nand

i know i should dump my nand without AutoRCM installed
if i launch sx os menu i click uninstall AutoRCM do i need to restart my switch then dump my nand or can i dump it as soon as i uninstall AutoRCM without powering off my switch then back on

one raw dump + boot0/1 is enough. dumping on every firmware is overkill because none of the important console specific info changes during updates.

in theory you only need boot0/1 and prodinfo/f to restore a bricked console, everything else can be recreated or donated from another persons dump.

it actually depends on what you are using to dump it. iirc you need to do both. for sure reinx requires you to dump them separately using the toolkit.

    @BakerMan, Any idea what happened? I hope that your brother's doing good.
  • BakerMan @ BakerMan:
    Well, from what I've heard from my parents, he had a seizure last night, perhaps an epileptic episode, fucking died, had a near death experience, my dad called the paramedics, they showed up, took him to the hospital, and he woke up covered in tubes, and started complaining.
  • BakerMan @ BakerMan:
    He couldn't eat until after his MRI, when he had a bomb pop.
  • BakerMan @ BakerMan:
    What matters now is that he's doing alright.
