Head over to the relevant DJI downloads page and grab the latest firmware:
Phantom 3 Professional
Phantom 3 Advanced
Phantom 3 Standard
Phantom 3 4K
Unzip the downloaded file to a folder on your desktop. The firmware itself is inside the .bin file.
Insert your Micro SD card into the slot on the Phantom 3’s Gimbal.
Using the USB cable that was supplied with your Phantom, connect the Micro-usb port on the Phantom Gimbal with your computer. (Another way to do this is to remove the SD card and install it in your computer using a card reader.
Turn on your Phantom 3 drone as normal.
Copy the .bin file you’ve just unzipped to your desktop over to the ‘root’ of the SD card which should now appear as a storage device on your computer. The root just means the home location on the SD card, not within any folders or subfolders.
After the file has been copied, remove the USB cable that was connecting the aircraft and your computer. (Or remove SD card from computer and install it back in the aircraft.)
The aircraft will now upgrade the firmware automatically using the .bin file that you’ve placed on the SD card. This process will take some time, up to 40 minutes, so please don’t be alarmed if it seems to be taking some time. During the update process the device may make sounds, reboot or other strange behaviour – don’t worry – it’s part of the process.
Once the update has begun, you’ll see a small LED on the gimbal.
Flashing green then red – Firmware is still upgrading.
Solid green light – The firmware upgrade is complete.
Solid red – The firmware upgrade was unsuccessful.
As soon as you see the status LED on the Phantom 3 gimbal turn solid green without flashing, the firmware upgrade is complete.
It is also important to listen to what noises your gimbal is making: A beep ever half second indicates the updated file has been recognised and is being loaded, 4 beeps in a row means the file is installing and finally one beep followed by two shorted beeps indicates the update is complete and the craft can be switched off.
That’s it – the firmware upgrade is now complete.
Please remove the .bin file from the SD card before continuing to use your aircraft.
