Give it a try again the last time but using windows.
My daily setup runs Linux desktop, but only using Windows to format SD card to FAT32 and uploading firmware.bin work.
So give it a try, good luck!
Take a firmware.bin and config from this thread on Reddit:

Good luck and have fun!
(but be aware that i am not sure that every thing will work as expected)
