So, I've been off for awhile and now there's a new update 11.5. I have custom firmware in my O3ds and I luma 6.6 still. Apparently there's a new B9S, which I have no idea what it is, and that luma can only be updated on it. My questions are: I'm on 11.4. Can I update to 11.5 freely? Or do I have to update my luma first? If so, how can I update it??
