How to update the SOMA Laboratory Flux

1. Download the latest .smf firmware file from somasynths.com/flux_firmware/. 2. Put it in the root folder of a FAT32 USB stick (1-32 GB). Keep only one firmware version on the stick. 3. With FLUX powered off, insert the stick, then turn FLUX on. It enters USB drive mode. 4. When the screen shows UPDATE?, press sensor A. Do not turn FLUX off during the update. 5. When OK appears, remove the stick; FLUX returns to normal mode. If a cross sign appears, turn FLUX off and on, download the file again or try another USB stick.

Just for reference. For complete and up-to-date instructions, always refer to the manufacturer's official firmware page.
