So i want to completely delete everything like all my hacks and everything and just start from the beginning. My sd card is filled with sooo many things that i dont even know what is useful and what isnt. I dont know what my stock switch firmware is at or anything. I am just genuinely lost so what is the best way to completely wipe everything and then start again?
If no NAND backup you can't easily restore to a point where you can go online and game. there is a way to manually clean your logs and try to restore to a clean slate but its extremely complex and not 100% proof. I'd only go down this path if your hell bent on going online.
Your other option as others have said is to turn off autoRCM, restore to default, and pray when you go online you don't get banned. if you do, then your back to where you were before anyway and have to do everything offline.
You said your Switch isn't patched, so if you really want to erase it just turn off auto rcm and factory reset it.
To turn off Auto RCM just boot hekate and enable then disable autorcm. That should do the job.
If you are using ams, you don't really have to care about autorcm, as it shutdowns properly. The only time you need your dongle is when you power it on (and have autorcm) if you're using ams.
