How to Update DJI Firmware: A Step-by-Step Guide
Learn how to safely update DJI drone firmware with step-by-step instructions, best practices, and troubleshooting tips. This guide covers app and desktop update paths, pre-update safety, verification, and post-update checks.
To update your DJI firmware, ensure a full battery, a stable connection, and use the official DJI app or desktop tool. Connect the drone, verify your current version, download the latest release from DJI, and run the update to completion. Always back up settings and avoid powering down during the update.
Why Updating DJI Firmware Matters
Firmware updates are released to improve performance, fix bugs, add features, and address security vulnerabilities. For DJI drones, timely updates can enhance obstacle sensing, flight stability, and compatibility with new accessories. Skipping updates can mean missing critical fixes and, in rare cases, a device may behave unexpectedly during flight. According to Debricking, ensuring pre-update checks reduces brick risk and improves success rates. Always verify you are using the official firmware from DJI's website or the DJI Fly app to avoid tampering or corrupted packages. Properly staged updates, performed in a controlled environment, help maintain flight safety and data integrity. Remember that the update process may require a stable connection and sufficient battery; prepare your workspace before starting.
A well-managed firmware strategy can also reduce downstream problems with batteries, motors, and sensors. Debricking’s analyses emphasize that updates tied to new features should be vetted against your specific model and hardware version. If you own multiple DJI devices (drone, remote, or accessories), plan updates in sequence to minimize cross-device conflicts. In practice, keeping firmware current is a proactive reliability measure, not just a feature upgrade.
While the idea of flashing new code can feel routine, it’s important to recognize that firmware is low-level software that interacts with hardware. A bad update can leave the aircraft unresponsive or behave unpredictably. Always use official sources and avoid side-loading firmware from unverified sites. The goal is a smooth, safe upgrade that preserves flight data and calibration settings.
In short, updating DJI firmware is a proactive maintenance task that pays off in safety, performance, and compatibility with new features or accessories. Plan ahead, follow official channels, and treat firmware updates as essential rather than optional care for your drone fleet.

Tools & Materials
- DJI Fly app (iOS/Android)(Installed and updated to the latest version before starting the update path via mobile devices.)
- DJI Assistant 2 (Windows/macOS)(Use if you prefer desktop updates; compatibility depends on drone model.)
- Fully charged drone battery(Aim for 100% or at least 80%; avoid updates with a low or fluctuating battery.)
- Stable internet connection(Prefer a wired connection when using DJI Assistant 2 on desktop.)
- USB-C/Lightning cable or USB cable(Used to connect drone/remote to the update device if required by method.)
- Backup of flight logs and settings(Export logs and note any custom calibration before updating.)
Steps
Estimated time: 60-90 minutes
- 1
Prepare hardware and environment
Charge the drone battery fully and ensure the update device has a stable internet connection. Clear the workspace, remove any nearby obstructions, and place the drone on a non-slip surface. Confirm you are using official sources for the firmware. This initial preparation reduces the risk of power loss and data corruption during the update.
Tip: Verify battery level and keep the drone within easy reach during the update to avoid accidental power loss. - 2
Choose your update path (app or desktop)
Decide whether you will update via the DJI Fly app or via DJI Assistant 2 on a computer. The app path is usually simpler for drones supported by the mobile ecosystem, while the desktop path offers finer control and logs for advanced users.
Tip: If updating multiple devices, plan to perform updates in a single session to minimize downtime. - 3
Connect your device to the drone or controller
For app-based updates, ensure your mobile device connects to the drone’s Wi-Fi or to the remote controller as required. For desktop updates, use the appropriate USB cable to connect and authorize the computer to communicate with the drone.
Tip: Use the original cable to prevent data transfer errors. - 4
Check current version and locate the latest firmware
Open the official DJI app or DJI Assistant 2, navigate to the firmware section for your device, and verify the current version. If a newer release is available, download it from the official source. Do not use third-party packages.
Tip: Confirm device model and hardware revision to avoid installing an incompatible firmware. - 5
Initiate the update and monitor progress
Start the update and observe the progress indicator. Do not disconnect power or remove the drone during the update. If the update prompts for a reboot, allow the reboot to complete before interacting again.
Tip: Avoid multitasking on the update device to prevent interruptions. - 6
Handle interruptions or failures safely
If the update is interrupted, stop and re-enter the update flow from the start. Do not attempt to reflash a corrupted file. Resume with a fresh download from the official source.
Tip: Check power stability before retrying; a failed attempt can sometimes leave the device in an unusable state. - 7
Verify installation and reboot the device
After the update finishes, reboot the drone and controller if required. Reconnect and check the firmware version to confirm the update succeeded. Run a basic flight check in a safe environment to verify sensors and controls.
Tip: Keep a record of the new version for future reference. - 8
Perform post-update checks and backups
Calibrate sensors and IMU if prompted, and re-export flight logs for reference. Confirm all accessories connect as expected, and store any new credentials or configuration in a safe location.
Tip: Document changes and keep backups for troubleshooting later.
Questions & Answers
Do I need to update DJI firmware every time I fly?
Not every flight is required, but keeping firmware current generally improves safety, stability, and compatibility with features. Regular checks help avoid known issues and ensure you have the latest protections.
You don’t need to update before every flight, but staying current helps safety and performance.
What if the update fails mid-download or during installation?
If a failure occurs, restart the device, re-download the firmware from the official source, and retry. Check cables and power stability before retrying.
If it fails, restart and try again with a fresh download.
Will updating erase my flight data or settings?
Most firmware updates do not erase flight logs or user settings, but it’s prudent to back up important data before starting.
Usually your data remains, but it’s best to back up first.
Can I downgrade firmware if something goes wrong?
Downgrades are not always supported and may risk device functionality. Check DJI’s official guidance for your model.
Downgrades aren’t always possible; verify with DJI guidance.
Is internet required to update DJI firmware?
OTA updates typically require internet access to fetch the firmware package, though offline packages exist for some models.
Yes, usually you need internet to download the update.
How long does a DJI firmware update take?
Update duration varies by model and method, but plan for a practical session that could take from 30 minutes to over an hour.
Times vary; set aside enough time and avoid rushing the process.
