To find the current version of your Netduino firmware:
1. Go to the Start Menu > Programs > Microsoft .NET Micro Framework 4.2 > Tools
2. Run MFDeploy.exe. Be careful to run MFDeploy.exe and not MFDeploy.exe.config (as file extensions are hidden by default)
3. Plug your Netduino into your PC using a Micro USB cable.
4. In the Device section at top, select USB instead of Serial. Your Netduino should appear in the drop-down; if not, select it.
5. Select the Target menu, Device Capabilities option.
6. In the output box, find the "SolutionReleaseInfo.solutionVersion" value. This is your firmware version.
To flash this firmware:
1. Detach your Netduino
2. Press and hold your Netduino's pushbutton while plugging it in via USB; this will put it in bootloader mode.
3. Erase the firmware on your Netduino using the STDFU Tester v3.0.1 application
> a. Select the "Protocol" tab

About Device Firmware:
Applying a newer firmware version than the one already installed on your unit can bring various enhancements, include workarounds for diverse problems encountered by the device, and improve or add newly developed features.
On the other hand, downgrading the firmware version can recover the device’s functionality in the event of a software update either turning up faulty or causing the unit’s overall performance to drop. However, bear in mind that applying an older firmware isn’t recommended and might not always be possible.
When it comes to the update steps, due to the large variety of devices and numerous ways for installing a new firmware, it is recommended that you carefully read and understand the upgrade steps, and consider applying a different firmware only when you have familiarized yourself with the update method.
As the installation process is most of the times quite risky, this step should be taken by users that have the ability to successfully complete the update; regular users may initiate it at their own risk. Moreover, it’s best that this task be performed in a steady power environment such as the one ensured by a UPS unit.
Therefore, if you consider applying this release, hit the download button, take into account all the aforementioned aspects, and update the device’s firmware. Also make sure you constantly check with our website to ensure that you don’t miss a single new release.
