About FC Firmware
New FC features and fixes are released through firmware for the host — Axe-Fx III, FM9 or FM3.
The FC also has its own internal firmware for basic functions, however, and this is also sometimes updated.To determine the firmware version installed in your FC unit, re-start it and watch its main display.
Installation instructions for new firmware are included in the zip files below.
IMPORTANT: FC “Original” units require different firmware update files than FC “Mark II” units. Please be sure to choose the correct file below. Accidentally installing the wrong version will not damage your FC, but you will need to install the correct version before it will function properly again.
