Hacking Question Clean Nand backup?

[zingerburger]

Just wanted some advice on wether my Nand backup is considered clean?

This is what I did from a switch that had never been hacked.

I setup the sdcard using sdfiles, then pushed payload. Didn’t realise I had to push volume down button after payload to get into cfw menu where you can do backup from. Switch booted with CFW to lock screen, I turned off switch straight away and then reset into boot menu and did nand backup.

Question is, is my nand backup clean?

You're backup is very likely clean if all you did was boot CFW for a second.

That’s what I’m hoping, as I never even went into the cfw menu or anything else, was just worried that even loading into the switch could have dirtied the nand.
