Firmware Update Procedure:
 
  1. Download and unzip desired firmware version at the top of this article.
  2. Locate the micro-USB port and firmware update button on the underside of the amplifier chassis beneath the OUTPUT POWER section.
  3. Power on the amplifier while holding the firmware update button for at least 3 seconds.
  4. Once booted (approximately 10-15 seconds), the firmware update LED next to micro-USB port will slowly blink to indicate that the amp is in firmware update mode.  The power jewel located on the front of the chassis will also cycle between amber and red.
  5. Connect a USB data cable from the Tone Master amplifier to your MAC or PC.  USB Charging cables may not work if data lines are not connected.
  6. The amplifier will appear on your computer as a mass storage device named FENDER_AMP (similar to USB flash and external hard drives)
  7. Drag and drop the firmware update .img file onto the FENDER_AMP folder.
  8. The Update LED will blink quickly to indicate the update is being applied, this process should continue for approximately 30-60 seconds.
  9. Once the update has completed successfully the firmware update LED will stop blinking and remain ON and the amplifier will auto eject from the computer.  Note some MAC user may receive a Disk Not Ejected Properly message.  This is normal and not an error.
  10. If update was successful, disconnect the USB cable and power cycle the amplifier to return to normal operation.
  11. If the update was unsuccessful, the firmware update LED will stop blinking and remain OFF. Power cycle the amplifier and repeat update procedure beginning at step 3.
