Great you got it working.
So I also dove into it

I managed to get 2.4.2 installed on solo and artoo.
When I go to solo app (not solex), to check the gimbal FW, I see the little circle, just doing it's thing... never actually a number.
Is there any other way to check the gimbal FW?
I ran the first command, copied 2.4.2 on both with WinSCP, and ran the second command. no errors. Artoo gave the info on LCD, Solo just rebooted, and stayed there with red leds. I manually power cycled the bird and I guess it installed on boot. I think I did it correctly.
I still can't start recording from SOLEX, or change gopro mode (I have a feeling that this is connected to the before mentioned issue). Something I never really needed, but wanna try, just becasue it's here
