RGB30 Firmwares

Here as of 2026-02-13 there seem to be two big firmwares used on RGB 30.

1. rocknix replaced Jellos
2. darkos replaced arkos

I almost went with Rocknix, but noticed it hasn't been updated since mid 2025 and many say there can be power issues with it on the RGB 30. DarkOS just got updated 2 weeks ago and has no power issues. Still from what I hear rocknix is more polished whatever that means. Regardless I am going to go with dArkOS_RGB30_trixie_01312026.img.
