Yes but I don't see my Audya when I connect it to my PC .. That is the problem !!! The Audya stop before I can access to the menu so I can't active the USB connection.
try this:
1- Power on your PC
2- Connect USB cable from Audya to PC
3- Power-up the audya and wait until you see and USB icon in the display of the keyboard
4- Then do the upgrade
IF you still fail to see the Audya in you PC (my computer) then try:
5- Power-up you Audya holding down the F10 and Unplugged keys
