So I got my Switch a couple of months ago. It was on some 3.x firmware so I decided to let it stay that way, not upgrading and then stopped using it due to lack of time mixed to fear of upgrading and losing any possible "new" exploit.
Now I will have some more free time and mostly I want to finally USE it
I still want to preserve as much as possible the original firmware (i.e. no fuse burning and the minimum modifications possible to original filesystem etc.) "just in case". If I understand correctly what I read in the past months, I can "hack" my switch and then upgrade without burning fuses with "ChoiDujourNX" homebrew, then use AutoRCM to avoid any unwanted reboot to original bootloader. Is that right or did I forget something important?
I would also like to try some games before buying them, so running so-called "backups" would be required for me.
So, for now I am completely clueless on what the best course of actions would be. I definitely need to backup everything that I can, so the first question is: what is the current best way to achieve a full (and fully usabble) NAND backup with the less modifying needed on the system?
And after that, is that just a matter of "installing" a custom firmware (I think ReiNX is the current only free one available and with all the functions I'd need), right?
I could also decide to spend some money on the paid CFW (SX), I am not sure if it is the only one with EmuNAND capabilities at the moment, or if that is needed at all. What I would like, obviously, is to be able to choose between running my backups, I think offline is the only way to go, and using a "clean" system with original games and maybe online content/services from N.
Now, this is where I understand that I... did not understand almost anything... I tried studying and reading many past threads, but I am still scared of damaging my console and of being banned by N.
I wish there was an up-to-date noob-proof guide, but it looks like I am not able to find such. So, here I am asking for help: please help me from the beginning, hopefully this is the right place to ask that
