The importance of keeping your firmware up to date just can’t be undersold. Keeping up to date with the firmware is of the utmost importance.

Yes, there will be times when the update isn’t all it was intended to be, sure, but mostly, it does improve flight parameters and fix known bugs. These are good things, even if, on the rare occasion, they break more than they fix.

You can think of firmware as being a middleman between your devices and the manufacturer. They’ll issue updates as needed when they uncover a bug or error in the software, or when there may need to be an update to the security.

Or when, once and a while, they want to bring out a new feature to an existing product. Of course, new feature updates are always appreciated, as new features are always nice.

Let’s get you covered on how to keep your DJI Mini 3 up to date on its firmware.

How to update the DJI Mini 3 Firmware #

When it comes to updating the DJI Mini 3, we have options. There are three ways that your DJI Mini 3 can be updated.

The first two methods are right through the DJI Fly App itself and are probably the easiest methods to go with.

The third method is by using your PC or laptop and using the DJI Assistant 2 App (link). When going with the third option, you will want to be sure to be using the right DJI Assistant App.

Note: For the DJI Mini 3, you need DJI Assistant 2 (Consumer Drones Series).

Before we cover that, let’s go over both of the in-app options we have for updating the Mini 3’s firmware.

Updating DJI Mini 3 Firmware through the Fly App #

If you’re using the DJI Fly App to update the Mini 3’s firmware, an internet connection will be required. Whenever updating the firmware, you should have a good solid internet connection, as you don’t want to get a failed download.

Once you’re online, follow the steps below:

Method 1 #

  1. Power on the aircraft and the controller.
  2. Once the two devices are on and linked, the Fly App will automatically check for any firmware updates for the aircraft and controller.
  3. If an update is available, a notification will appear on the screen.
  4. Tap Update.
  5. The update will initiate.
  6. The aircraft will automatically restart once the update is complete.

That’s it! No, really, that’s it. Easy, Peasy, right?! The DJI Fly App, as part of its startup and system checks, will verify the firmware you’re currently using and see if there are any needed updates.

Method 1 is mostly an automatic process that occurs when powering the craft on.

Another means of updating your Mini 3 firmware is by checking to see what version your app is running within the DJI Fly App itself. Unlike method 1, this is not an automatic function and has to be initiated by the operator.

Below you can find the steps for Method 2:

Method 2 #

  1. From the main DJI Fly App screen, tap the three dots or the vertical ellipsis in the upper right-hand corner. This will open the main setting page.
  2. From the main setting page, tap on the option marked ABOUT. This will bring up the information page for your Mini 3. It’s on this page you can find such information as the current firmware, the aircraft serial number and other useful information.
  3. Go to the firmware and tap CHECK FOR UPDATES. If there is a newer version of the firmware, you can tap the tab, and it will download and install the latest version for you.

Although this method is a bit more involved, it can be used with the aircraft and controller already powered on and without having to power the craft off and on again.

As stated, these two methods are the easiest as they don’t require doing anything else outside of the DJI Fly App.

Method three, however, requires the use of a PC or laptop and involves connecting the DJI Mini 3 to that device via a USB-C to USB cable. The DJI Assistant 2 App can also do more than just check the firmware and update though.

In the DJI Assistant 2 App, you can also calibrate the sensors, gain access to the black box, do flight calibrations, run the simulator, and do an easy-to-use factory reset.

The DJI Assistant 2 App really is quite a handy toolbox, and if you have yet to become acquainted, it is definitely something you want to make your acquittance with.

Updating DJI Mini 3 Firmware through DJI Assistant 2 #

Now our third method, as stated above, will require the use of a PC or laptop and a cable connection. I can’t stress enough that you will want to be sure to be using the right DJI Assistant 2 App.

Note: The correct one for the DJI Mini 3 is the DJI Assistant 2 (Consumer Drones Series).

DJI has multiple Assistant 2 Apps covering the whole of their product line. It can be easy to download the wrong one.

The steps for method 3 are as follows:

Method 3 #

  1. Begin by powering ON the aircraft.
  2. Use a USB cable to connect the aircraft to the computer.
  3. Launch the Assistant 2 application and log into your DJI account.
  4. The DJI Mini 3 should show up as a selectable tab. Select the aircraft.
  5. Here you should see a button for “Firmware Update.”
  6. Click on it, and the Assistant 2 app will refresh the firmware list.
  7. Select the firmware version you’re looking to upload and click. This will begin the update. Whenever you’re doing a firmware update, ensure the device remains powered on during the updating process.
  8. Once that update has been completed, exit the Assistant 2 app and disconnect the aircraft from the computer. The drone should automatically restart, indicating the update is complete.

Much as we have done with the aircraft, we can follow these steps to update the controller as well. Now these are the three methods by which you can update your DJI Mini 3.

Before you go though, we should cover updating the DJI Fly App, as two of the methods we have walked through will require that we’re using the most up-to-date DJI Fly App.

How to update the DJI Fly App #

If you don’t have the most up-to-date DJI Fly App, method one from above may not work. Meaning you may not be receiving update notices as you should, leading to the aircraft’s firmware becoming out of date without you knowing.

Before we can ever update the aircraft or controller and know we have the most up-to-date firmware, we will need to know we have the most up-to-date DJI Fly App.

You may have noticed that above we covered the steps to find the firmware version and update it in method 2. We can follow the same steps to see what version DJI Fly App we have and update it as well.

We can also access the DJI Fly App’s firmware through the Profile page. We’ll put those steps below.

Updating within the App #

  1. Open the DJI Fly App‘s main start screen.
  2. Tap Profile.
  3. From the profile page on the right side, tap Settings.
  4. This will open the settings page. Here, you can check for Fly app updates.
  5. If there is one available, select it, and the update will start downloading.
  6. Once the app is updated, you can then proceed to update the Mini 3’s firmware with one of the methods above.

To reiterate, this method is through the settings from the Profile section of the DJI Fly App. The same can be done following Method 2 above from inside the DJI Fly App.
