Guy, I just did it. So much about our exchanges this morning.
The instructions, loosely translated, say:
Format the card in the camera.
Turn off camera, put card in cardreader.
Move the downloaded m8-1 . . etc stuff onto the second line of your card folder display - below DCIM
Put the SD card back into camera and turn it on.
Agree to have the new firmware installed.
It takes about 180 seconds.
Good Luck.
