Have you tried a different USB lead?

The USB connection was a little bit strange as the laptop did not expand the QMX device icon to show it?s contents.
I ignored that strange behaviour and dragged the firmware file to the QMX device icon and it seemed to me that the file transfer started.
But immediately thereafter, the laptop showed a message "USB connection aborted" or something like that.
QMX did not react to the power button, (or maybe did, but the display did not activate).
I tried to use the AUX - GND wire method to force the QMX to firmware update mode, but no success. The laptop did not detect the QMX.
It is obvious that there was some problem with my laptop. The laptop was running with battery power.
Now using my desktop PC does not help, the PC does not detect the QMX.

What to do?
?
 

The USB cable is OK.
The problem is in the QMX:
What happens when the firmware update process is interrupted?
Is it possible that the firmware gets corrupted so that there is no working firmware?
 

When you force firmware update method be sure you are connecting between AUX2 and Ground. I looked at the?picture and connected between the two red arrow points. Be sure you are connecting between either of the RED arrow points and either of the GREEN arrow points. If you go between the two red arrow points your computer will give you the error message. I and a friend did the two red arrow points..duh!
