Nissin MG10 Flash Firmware Update Instructions

Nissin MG10

Nissin MG10 flashes have user-upgradeable firmware. That means that you can update the internal software that runs the MG10 in order to add compatibility with new cameras, fix problems, or to add features.

The MG10's firmware can be updated by downloading current firmware files to a MicroSD card (FAT32 formatted) and inserting the MicroSD card into the MG10 flash to perform the update.

How to Check a MG10 Flash's Current Firmware Version:

1. Make sure the MG10's power is off.

2. Press and hold the Power button and the Pilot button at the same time for 5 seconds.

3. The Pilot LED will begin blinking the number of the consecutive blinks equals the number of the currently installed firmware version (e.g., 7 blinks equals firmware v.7).

How to Update the MG10 Firmware: 

1.  Download the appropriate MG10 firmware update file to your computer.   Scroll down to the bottom of the MG10 Product Page at and click the "Download" button next to the firmware version for your camera brand.  Open the .zip file downloaded to your computer, and you will find a folder with two .hex files inside it.
Insert SD Card
2. Insert a MicroSD card into your computer's card reader and make sure that that card is formatted in FAT32 format.
 Computer Copy
