I'm afraid I'm the one who started the thread on the Leica forum. My M8 needs to go back to Leica as it is dead as a door nail after "upgrading" the firmware. It is a real problem for real people. I followed the instructions to the letter as best I can recall. After installing the firmware, the screen instructed to turn the camera "off" then back "on". When I did this the red light came on and stays on, even when the camera is shut off, and it is dead, nada.....
😕
