After discovering a bug in their most recent M10 firmware release (1.7.4.0), Leica has quickly issued another firmware update for the M10: firmware 1.9.4.0. The new firmware has the same SD card compatibility improvements found in 1.7.4.0 but fixes a bug that could case black images when shooting very short exposure times.  You can read more about the SD card improvements from the 1.7.4.0 release here: Leica SD Card Compatibility Improvements.

You can download the latest M10 firmware here: M10 Firmware 1.9.4.0

We also made a short video tutorial on how to update your M10 firmware:

The full release notes, from Leica:

With the previous firmware 1.7.4.0 a larger selection of SD cards were made compatible with the Leica M10. Unfortunately we discovered, that in certain cases, the firmware 1.7.4.0 could produce black images when using short exposure times.

This bug has now been fixed with firmware 1.9.4.0. All improvements from previous firmware versions are included in firmware 1.9.4.0. We apologize for any inconveniences this may have caused.
