I did one once. Managed to somehow install Catalina on a Lattepanda sbc. I would’ve never expected it to work, so I was positively elated.

The thing then promptly shorted, let out the magic smoke, and I haven’t tried anything similar since. Took it as a sign from the universe that if I were meant to be good at it, i wouldn’t have managed to fry aforementioned sbc, and several other ones (2 Jetson nano’s as well).
