First i wanted to say thanks for the quick answer and I hope I'm not to annoying if I have some follow up questions.
Untethered coldboot definitely does sound quite a bit more convenient. But I assume if I didn't care for downgrading I could just use the game card update and burn the fuses.
This makes me wonder, if you are on a low fw how do you even play games that require a higher one? Do you need an emuNand for that to work?
Hm, the whole game card slot update thing wasn't mentioned in the guide they put online for Reinx. They should add that, it's quite important information. (correct me if I'm wrong and just didn't see it, but I don't think it was in the guide. Or ChoidujourNX for that matter.)
Btw do i place that nogc file into the root of the SD or a specific folder?
And about that firmware switching.
If I have a certain firmware installed and want to use another one, do I just replace the files on the sd card and go through the install for the new cfw? Or could that damage my system and I need to "uninstall" the old one first?
Sorry for all the dumb questions, but I just haven't used any cfw for my switch yet and wanted to make sure I know what's best to do and how it works before I make some unnecessary mistakes.
