Encountering a DJI firmware update that continuously restarts can be a frustrating experience for any drone pilot. This issue often prevents the drone from operating correctly, grounding your aerial adventures. This comprehensive guide will provide you with a step-by-step approach to diagnose and resolve the DJI firmware update restart loop, ensuring you can get back to flying safely and efficiently. We will explore common causes and practical solutions to get your drone airborne again.
Understanding the DJI Firmware Update Restart Loop
A firmware update restart loop occurs when the drone’s system fails to properly install the new firmware, causing it to repeatedly attempt the installation process. This can manifest as the drone powering on, showing signs of updating, then restarting without completing the process.
Several factors can contribute to this problem. Interrupted downloads, corrupted firmware files, insufficient battery power, and hardware incompatibilities can all trigger the restart loop. Identifying the root cause is crucial for selecting the appropriate solution.
Common Causes of Firmware Update Issues
Before diving into solutions, let’s examine the common culprits behind DJI firmware update problems.
- Interrupted Download: A disrupted internet connection during the firmware download can lead to incomplete or corrupted files.
- Corrupted Firmware File: Even a complete download can result in a corrupted file if there were errors during the transfer process.
- Insufficient Battery Power: Firmware updates require a significant amount of power. A low battery level can cause the process to fail and enter a loop.
- Hardware Incompatibility: In rare cases, new firmware might have compatibility issues with older hardware components within the drone.
- Software Conflicts: Conflicts with other apps or software on your mobile device can sometimes interfere with the update process.
- Damaged SD Card: A faulty or damaged SD card can prevent the firmware from being properly written to the drone.
Troubleshooting Steps to Fix the Restart Loop
Follow these steps in order to troubleshoot and resolve the DJI firmware update restart loop:
1. Ensure Sufficient Battery Power
The first and simplest step is to ensure that both your drone and remote controller have ample battery power. DJI recommends a battery level of at least 50% for both devices before initiating a firmware update. Connect both devices to their chargers and allow them to reach a sufficient charge level before proceeding.
2. Restart Your Devices
A simple restart can often resolve temporary software glitches. Power off your drone, remote controller, and mobile device. Wait for a few seconds, then power them back on in the following order: remote controller, then drone.
3. Check Your Internet Connection
A stable and reliable internet connection is crucial for downloading the firmware file. Ensure you are connected to a strong Wi-Fi network or have a stable cellular data connection. Avoid updating firmware in areas with weak or intermittent signal strength.
4. Use DJI Assistant 2
DJI Assistant 2 is a desktop application designed for managing and updating DJI products. This method often provides a more stable and reliable update process compared to using the mobile app.
- Download and install DJI Assistant 2 on your computer from the official DJI website.
- Connect your drone to your computer using a USB cable.
- Launch DJI Assistant 2 and follow the on-screen instructions to update the firmware.
5. Force Firmware Update via DJI Assistant 2
DJI Assistant 2 allows you to force a firmware update, which can sometimes bypass the restart loop. After connecting your drone to the computer and launching DJI Assistant 2:
- Navigate to the firmware update section.
- Look for an option to “Force Update” or “Refresh Firmware.” This option may be hidden or require clicking on the current firmware version.
- Follow the on-screen prompts to initiate the forced update.
6. Downgrade Firmware (If Possible)
If the issue persists after attempting a forced update, consider downgrading the firmware to a previous version. This can help determine if the problem lies with the latest firmware release. Use DJI Assistant 2 to select a previous firmware version and initiate the downgrade process. Be aware that downgrading firmware may not always be possible or recommended, as it could introduce other compatibility issues.
7. Check and Replace the SD Card
A faulty SD card can hinder the firmware update process. Remove the SD card from your drone and inspect it for any physical damage. Try using a different, known-good SD card and attempt the firmware update again. Ensure the SD card meets the recommended specifications for your DJI drone.
8. Clear Cache and Data of DJI Apps
Corrupted cache or data within the DJI GO 4 or DJI Fly app can sometimes interfere with the firmware update process. Clear the cache and data of the app on your mobile device:
- Go to your device’s settings.
- Find the “Apps” or “Application Manager” section.
- Locate the DJI GO 4 or DJI Fly app.
- Tap on “Storage.”
- Tap on “Clear Cache” and “Clear Data.”
After clearing the cache and data, restart your mobile device and attempt the firmware update again.
9. Reinstall the DJI App
If clearing the cache and data doesn’t resolve the issue, try uninstalling and reinstalling the DJI app. This ensures you have a fresh installation of the app, free from any corrupted files or settings.
10. Check for Error Codes
Pay close attention to any error codes displayed during the firmware update process. These codes can provide valuable clues about the underlying cause of the problem. Refer to the DJI documentation or online forums to research the meaning of specific error codes and potential solutions.
11. Contact DJI Support
If you’ve exhausted all other troubleshooting steps and the firmware update restart loop persists, it’s time to contact DJI support. They can provide expert assistance and guidance, potentially identifying hardware issues or offering advanced solutions.
Preventing Future Firmware Update Issues
Taking preventative measures can minimize the risk of encountering firmware update problems in the future.
- Maintain a Stable Internet Connection: Always update firmware in an area with a strong and reliable internet connection.
- Ensure Sufficient Battery Power: Charge your drone and remote controller to at least 50% before initiating an update.
- Use DJI Assistant 2: Whenever possible, use DJI Assistant 2 for firmware updates, as it offers a more stable process.
- Regularly Format Your SD Card: Format your SD card regularly to prevent file corruption.
- Keep Your DJI App Updated: Ensure you have the latest version of the DJI GO 4 or DJI Fly app installed.
- Read Release Notes: Before updating, review the firmware release notes to identify any known issues or compatibility concerns.
Conclusion
A DJI firmware update stuck in a restart loop can be a frustrating obstacle, but by systematically following the troubleshooting steps outlined in this guide, you can often resolve the issue and get your drone back in the air. Remember to prioritize a stable internet connection, sufficient battery power, and the use of DJI Assistant 2 for a smoother update experience. If all else fails, don’t hesitate to contact DJI support for expert assistance. With patience and persistence, you can overcome this challenge and continue enjoying your aerial adventures.
By understanding the common causes and implementing the appropriate solutions, you can minimize the risk of future firmware update problems and keep your DJI drone operating at its best.
