Just a warning. Installed the new firmware on my M8 and it trashed it. Followed all the procedures as usual and camera will not startup now. And yes I followed all the procedures as I have done with all previous updates. I have had very few problems with this camera so feel it was just bad luck but Leica needs to address these rudimentary problems in a professional level camera. A basic reset firmware built into the rom would allow recovery instead of a trip in for service.
