Your DJI drone should have been packaged with what is known as an USB-OTG adapter.

What Is a USB-OTG Adapter?

USB On The Go adapters act as a host between two USB devices, allowing them to both physically connect and communicate with one another.

If you cannot locate your device's USB-OTG adapter, you must purchase one separately.

Connecting Your Drone

  1. Connect the microUSB end of your USB-OTG adapter into your drone.
  2. Now, using your mobile device's charging cable, connect the standard USB end of the cable into your USB-OTG adapter, and the other end into your mobile device.
  3. Make sure the cabling is connected correctly and firmly.

When using the DJI GO app on your mobile device to update firmware, a Wi-Fi connection is recommended. If your device loses Wi-Fi signal, or if the app quits unexpectedly, this can lead to failed upgrade attempts. The App will remind you that your device should be connected to Wi-Fi before attempting to download firmware if it is not currently connected via Wi-Fi.

  1. Confirm that your Wi-Fi connection is stable, has good signal strength, and is working properly.

Depending on what device (Smartphone or Tablet) and which generation you have, the menu theme and options might look slightly different on your screen. However, the steps should be similar across all Android devices and generations.

Contents of the Card

  1. With the way DJI updates, there should be no reason to mess with the contents of your SD Card.
  2. In the event you need to check the contents of your card, do not rename the file you have downloaded.
  3. Do not download more than one firmware version on the SD card. This will cause the update to fail.
  4. You may need to format the SD card before you update.
