Datto Networking: Datto MP60: Flashing Device Firmware



This article describes how to flash firmware releases onto a Datto MP60 Managed Power device. Use this article to download the tools and firmware needed to flash the device, and as a walkthrough for the flashing procedure.


  • Datto MP60
  • Microsoft Windows 


On April 16, 2019, Datto updated our server certificates; MP60s not upgraded to firmware version 6.4.16 by that date no longer check in, preventing device management, reporting, and automatic upgrades. See this article for important information.

An MP60 may require a reinstall of its firmware as a troubleshooting step. You will need to flash the firmware release manually onto the MP60.


1. Install Npcap (external link) in the default WinPcap API-compatible mode.

2. Download the MP60 firmware flashing utility.

3. Open an elevated command prompt on the Windows machine containing the flashing utility, then navigate to the utility's directory.

4. Type in the utility's filename (in this example, open-mesh-flash-ng), then press Enter. A usage prompt will display.

5. Run the following command: open-mesh-flash-ng n, replacing 'n' with the number associated with the Ethernet port that will communicate to the MP60.

6. Connect your MP60 to the Ethernet port specified in step 4, and power it on. A crossover cable is not required. If the device was previously powered on, power cycle it before continuing.

7. Verify the output of the flash utility is similar to Figure 3. Once it is available on the network, the utility will display the device's MAC address and device type. If you chose a virtual NIC, additional devices might populate in the command's output before reaching the desired device.

The process will take three to fifteen minutes to complete. If nothing displays after ten seconds, power cycle the MP60, or connect to a different Ethernet port.

7. Run the command open-mesh-flash-ng -v to verify the MP60's current firmware version.

8. Exit the utility, or connect another MP60 to run the same flashing process.

Datto Networking Portal

After flashing the firmware, follow these steps in the Datto Networking Portal for your MP60:

1. Verify the MP60 is configured to run on the new firmware version, and disable automatic updates. You can find both configurations on the Maintenance page.

2. After reconnecting your MP60 to your network, pair it.

Recently flashed MP60s may take up to 40 minutes to check-in.
