Volumio Primo revert to version 2.x from 3.x

Hi! Because I have issues with version 3.x (e.g. DSD playback problems). I’d like to revert to ver. 2.916. I downloaded the volumio-2.916-2021-10-01-tinkerboard.img and flashed to an usb drive. But how can I set booting from usb and copy the image to the internal emmc memory? Thanks for helping

I have the solution: open the Primo case and connect the micro USB to a PC . When plug in to PC the Tinker Board S boots in UMS mode. Then write the image to the eMMC.

Good tip zolszal. :wink:
