Have you checked out the wiki?

thank you
You’re welcome
soo, i havent changed anything and it randomely decides to stark working, maybe it could be related to the fact that today was the day i installed flatpak. but now ots stuckon the same one (spinfinity) and i cant change it, i mean i can and have applied the changed settings multiple times and it shows as done everytime but actually doesnt change during boot.
Very much doubt it has anything to do with this.
Can you share the exact commands you used to try change the background? Otherwise we can only guess at what is happening.
i changed it through the kde settings menue
Thank you so much, @joekamprad . This is all I ever wanted to use with EndeavourOS. Works and looks great so far! 
I understand 
it’s a very easy snack to install the package and it sets up Plymouth completely automatically.
Yes! Just download the latest package and install it. Easy peasy…
I already tried installing Plymouth in the past, but it never worked.
