Why Firmware Updates Matter

DJI regularly releases firmware updates for its drones, controllers, and batteries. These updates deliver bug fixes, performance improvements, enhanced obstacle avoidance algorithms, new flight modes, and occasionally entirely new features. Flying on outdated firmware can mean missing critical safety improvements — or in rare cases, experiencing instability.

Updating your DJI drone is straightforward, but doing it correctly matters. Here's a complete guide.

Before You Start: Checklist

  • ✅ Batteries charged to at least 50% (drone and controller)
  • ✅ Stable internet connection (Wi-Fi preferred)
  • ✅ Latest version of the DJI Fly app (or DJI Assistant 2) installed
  • ✅ Enough storage space on your phone or computer
  • ✅ Do NOT interrupt the update once started

Method 1: Update via the DJI Fly App (Recommended)

This is the easiest and most common method for most DJI drones including the Mini series and Air series.

  1. Power on your drone and remote controller. Connect the controller to your smartphone.
  2. Open the DJI Fly app. Wait for it to detect your aircraft.
  3. If a firmware update is available, a notification banner will appear on the home screen or in the device connection menu.
  4. Tap the notification and select "Update" or "Update All" to update the drone, controller, and batteries simultaneously.
  5. The app will download the update package and push it to the drone. This typically takes 5–15 minutes depending on your internet speed.
  6. The drone will restart automatically once the update is complete. Do not power off during this process.
  7. Verify the update was successful by going to: Settings → About → Firmware Version.

Method 2: Update via DJI Assistant 2 (PC/Mac)

DJI Assistant 2 is recommended for Mavic 3 series, Inspire series, and professional drones. It also provides more control over the update process.

  1. Download and install DJI Assistant 2 from the official DJI website (ensure you download the correct version for your drone model).
  2. Connect your drone to your computer using a USB-C cable.
  3. Power on the drone.
  4. Open DJI Assistant 2 and log in with your DJI account.
  5. Your drone should be detected automatically. Click on it.
  6. Navigate to the Firmware Update section in the left sidebar.
  7. Select the latest firmware version and click Update.
  8. Wait for the download and installation to complete. Do not disconnect the USB cable.

Troubleshooting Common Update Issues

Update Fails or Gets Stuck

If the update stalls, do not panic. Keep the drone powered on. Close and reopen the DJI Fly app and check if the process resumes. If the drone is unresponsive after a failed update, connect it to DJI Assistant 2 via USB — it can often recover and complete the update from there.

"Aircraft Disconnected" During Update

Ensure your USB cable is undamaged and firmly connected. Try a different cable if available. USB-C data cables (not charge-only cables) are required.

Firmware Version Mismatch Warning

If the app warns of a mismatch between the drone and controller firmware, update both. Use "Update All" in the DJI Fly app to keep everything in sync.

Pro Tips for Safe Updates

  • Always update before a planned flying trip, not on the day of — give yourself time to troubleshoot if needed.
  • Check DJI's official release notes to understand what each firmware update changes.
  • If you rely on your drone professionally, consider waiting a few days after a new firmware release to let other users report any issues.
