Question Dynaudio Focus 20XD firmware update


Novice Member
I have a pair of focus 20xd speaker and I'm trying to update the firmware.
According to the step instructions from manual, during the update, the while LED's will blink, filling up from the bottom twice - first time is quick second is slow. Firmware update procedure is now finished

However, when I plug in the USB stick and power on the speaker, I could see only the red light is blinking fast for 1 min and it stops.

Am I doing the right way ?
