Hello guys.
I am using rasberry pi 3B model for ROV, but when I tried to open it, it doesnt open booting.
I did all the installing steps correctly(i hope) but rasberry gives me a rainbow screen.
How can I solve this problem?

Hi @enseri, welcome to the forum 
This comment should explain. It’s about BlueOS (rather than our old Companion Software), but the same reasoning applies. Feel free to follow up if you’re still confused afterwards.
