  5. Turn on the drone, then the remote control (both devices are turned on by double pressing – the first is short, the second is long).
  6. Make sure that the drone and the remote control are paired with each other (usually there is no problem at this stage, since the developer has carried out the process of pairing these components at the factory. However, it is rare, but it happens that the drone and the bullet are not paired. The pairing process itself is simple, do everything as in this video).
  7. Allow the application to access the photo gallery of your smartphone for the correct operation of all services.
  8. The DJI Fly app will automatically search for available firmware updates for the remote controller and aircraft. If an update is available, an Update icon will appear. Click on it to start the software update process.
  9. Do not turn off the power or exit the DJI Fly app during the update. The remote controller and the aircraft will reboot automatically during the update process, but don’t let that worry you. When the update is completed, the aircraft will automatically turn off and the remote controller will remain on.

When do you need to update the software?

Software updates are an important part of aircraft/component maintenance in the field and are usually a simple and intuitive process. The need for updating is set by the malfunctions identified during the operation of the drone. Also, new updates are released to correct security issues. From which it follows that the firmware should be updated only when the drone system asks for it.

However, as practice shows, the new firmware does not always bring improvements to the operation of devices and can sometimes be accompanied by its own errors. Therefore, if possible, it is recommended to refrain from the software update process until the new firmware has been confirmed to be correct for some time. This is because it can cause even more damage or render your drone unusable.

Why should you update the firmware?

Firmware is the backbone of all your drone operations. There are many reasons why drone pilots need to update their device firmware. Some of them are legal, others are personal. Here are some of the main reasons why you should update your firmware regularly.

Functionality improvements

The firmware controls all aircraft components, functions and operations, including batteries and incoming flight data from controllers. In particular, a firmware update provides the correct programming that your aircraft needs to perform its basic functions and ensure safety. Therefore, drone pilots, for whom the declared operational functionality of the copter is extremely important, are not recommended to abandon the firmware update process.


Firmware updates may improve the fail-safe landing feature, which can add reliability for emergency piloting. Drones are not cheap devices, and the last thing you want is to lose them. It follows that these updates address issues that affect the stability of your drone in flight and control, which increases the chances of a positive outcome in critical situations.

Drone manufacturers are constantly improving the software side of their products, and DJI is a prime example. For example, they have optimized their compass calibration program, thereby improving the flight reliability of drones.

Compliance with No-Fly Zones

This is one of the main reasons UAV pilots need to update their firmware regularly. From time to time, the developer more accurately adjusts the flight and no-fly zones, which allows the pilot to learn about their presence and boundaries in a timely manner. In particular, DJI has developed a firmware update in which the no-fly zone boundary received multidirectional extensions so that users would get into trouble with government agencies responsible for the operation of the airspace as little as possible.

Other reasons

  • Updates significantly reduce the cost of repairing or fixing problems.
  • Updates help bring hardware usage to optimal performance levels and allow algorithms to be decoded.
  • The updates eliminate delays in the drone system and significantly improve overall performance.
  • Firmware updates speed up the execution time of commands, which also has a positive effect on the operation of devices.

  • Make sure the drone/remote batteries are more than 50% charged.
  • Make sure you have a strong internet connection to avoid hitches during installation.
  • Remove the propellers.
  • Always check the settings (those you changed manually) after the update is completed.
