M-480: SYMPTOM: Unable to Update the Operating System

The most common reasons an update is unsuccessful are:

    • The downloaded update file has not been extracted (unzipped).
    • The "m480_sys_v1610" folder or the "m480_sys_v1610.zip" unzipped file was transferred to the USB memory. Only the "M-480.PRG" update itself should be transferred onto USB drive.
    • The "M-480.PRG" update file was not place in the root directory of the USB memory.

If the problem continues:

  • Try formatting the USB memory in the M-480 prior to updating the console: SETUP-->SYSTEM-->F6(USB MEMORY)-->F1(FORMAT).
  • Perform a speed test for the USB memory to be sure that it's functioning properly with the M-480:
    Press SETUP --> F6 (USB MEMORY) --> F7 (SPEED TEST).
  • Try a different compatible USB memory:
