avrdude done. Thank you.

Are you sure you are in DFU mode? I was able to flash it in ubuntu (on macOS under Parallels), but I entered DFU by connecting via socat and manually issuing upgrade command:

socat - /dev/ttyACM0,crnl,raw,echo=0
upgrade

Then I was able to use avrdude to backup and flash new.
