It's concerning to me that you have firmware available from your website but no instructions on how to install it.
It's like you want us to brick our devices.
The motherboard firmware seems easy enough, but should be documented. I have no freaking idea what to do with the screen firmware update. I've seen some posts but it all sounds like gibberish to me. I just want some simple put the file here, insert it here and then push this button... That kind of instructions.
I have a CR-6 SE with a 32bit board.
