With a paragraph like this, its hard to determine what are your questions and what is your backstory. Unless you specifically outline what you need help with, I recommend starting fresh with this guidenot quite sure if this is the right place for it please let me know or move if necessasary.
so i recently bought a switch witch cfw already on it and a rcm loader included. which was what i was looking for since i don´t know much about this. and when i casuallly looked at hacking a switch i found the whole process really confusing with google searches making me even more confused and often turning up contradictory advice. hence the pre hacked switch from ebay. the card is full with all kinds of stuff i´d say it´s littered with programs mostly also duplicates of tools. but no games
so i downloaded some games. starting sxos with the rcm loader was easy enough. but of the 20 games i tried only 2 of them worked. 15 said they were damaged and needed redownloading and only 2 actually made sense with their error message since they said something about updating the firmware. i´ve used hacked psps and vitas before so this made sense but of course i knew i couldn´t just update normally since this would destroy the hack. but when looking this up people said it´s not a problem as long as your cfw supports the firmware but other people said pretty much the opposite.
i´ve already updated sxos to the newest firmware (3.05) which should support the latest ofw 10.2.00
i already got the firmware but i´m hesitant to use it. the guide here says something about using ChoiDujour for that which happens to be already on the card but it also says to give it permission to write to bis (whatever that is) by placing a flag in my athmosphere folder so does this only work with atmosphere and not with sxos?
or can i just ignore this on sxos?
it also says somethign about auto rcm and ipatched consoles so what is a ipatched console? it clearly isn´t a patched console since those can´t be hacked i thought.
other guides talk about updating my emunand or sysnand or both with hekate no idea what that is or why that matters is this a hekate thing that can be ignored on sxos?
so do i need hekate or atmosphere or both for that?. other guides also strongly advice to back up my nand(s) / emummc before that by reading out the keys. which keys? and why does it matter?
