It took so long to find the energy to figure it all out, but I finally got the iPod Classic running RockBox reliably with my flac music library. And it's using the adwaita theme to match my laptop lol. I am so happy to be able to use it for listening to my music especially since I kinda broke my HiFiWalker H2 a few months ago.
