I’m getting ready to go shoot a wedding, and of course that’s when Leica decides to drop a firmware update. So in this video I walk you through exactly how I update firmware on the Leica M11 family using the SD card method (I demo on my M11-P, but the workflow is the same for the M11, M11-D, M11 Monochrome, and M-EV1—you just have to download the correct file for your specific model). I show what you need, how I prep, and the exact menu path to start the update. Before you start, I’m big on two safety things: make sure anything on internal memory is backed up (a firmware update will wipe it), and once the update begins, don’t touch the camera—no power cycling, no lens changes, no button mashing. I check my current firmware version, format the SD card in-camera, download the proper firmware from Leica’s website, unzip it if needed, and place the firmware file at the top level (root) of the SD card—no folders. I also cover the most common “why is firmware update greyed out?” issues: wrong model file, the file is still zipped, or it’s buried in a folder. After the update, I confirm the new firmware version, reformat the card so it’s ready to shoot, and quickly double-check things like date/time and my user profiles.
