I too have an ONDA D1800 BTC without english docs or manuals, who has managed to get it mostly working. I would like a little help so I do not cook it's BIOS while trying to Flash the upgrades to it.
First question can I just flash it with the last one dealing with the Vega fixes, or should I do all of them sequentially?
I prepared a Rufus 4gb usb key and loaded the 7zip uncompressed rar files onto it. I am able to get a C prompt on the screen output and see the Onda files with the curly thing when I do a dir. It has been a few decades since I last saw a C prompt. What do I do next to load the right files without mass destruction?

Thank you in advance.
