What To Do When Phantom 4 Update Fails 

If the Phantom 4 firmware update fails, try the following.  Delete the downloaded firmware file from your tablet or smart phone. Then download the firmware again.

Make sure that you downloaded the correct package for your Phantom 4 and follow the best practices below.  Also before upgrading the Phantom 4 or Remote Controller, the software app (DJI Go / Assistant 2 app) should be up to date.

If the update has failed with the DJI Go app, then try with the DJI Assistant 2. Be sure to connect your Phantom to the actual computer which has the DJI assistant on it and not from your phone or tablet. Once you’ve got it connected, you’ll need to reset your Phantom to its original factory state / setting pre-firmware upgrade failure and then try again to upgrade again.

Phantom 4 Firmware Update Best Practices

A firmware upgrade is a very important process.  The firmware download and upgrade to the Phantom 4 and RC needs to complete successfully.  The firmware is the critical software which makes the components on your drone work. So it is vital the firmware update process runs really smooth.

If a firmware download is interrupted or the firmware file is incomplete, then you would have to start the download process all over again.  More than likely, you won’t get the “start upgrade” option with an incomplete firmware file.

If the firmware file is incomplete or corrupt you could damage a component or your drone will just not fly.

With these steps you can avoid an unsuccessful firmware update.

Take Your Time

Never be in a hurry to do a firmware update.  The Phantom 4 firmware update needs approximately 1 hour from start to finish to be on the safe side.

It is also best to update the DJI Apps first, then the remote controller followed by the Phantom 4. So, check for updates for the following;

  • DJI GO App
  • DJI Assistant 2 App
  • Phantom 4 / Remote Controller

Think Safety And No Disturbance

Give yourself plenty of room and a quiet spot so you can concentrate without any disturbance.  Do not perform firmware update while the aircraft is still flying in the air.  Remove the propellers before starting the firmware process.

Fully Charged Batteries Before Firmware Update

Have at least 50% in your batteries before starting the update.  The best advice is to have fully charged batteries in your quadcopter, remote controller and mobile device (cellphone or tablet).

Downloading The Firmware Package

When downloading the firmware update package, make sure you have a very good internet connection. You don’t want to loose your internet connection while downloading the firmware package.  If you do lose the internet connection, it would be better to start the firmware download again.

Updating the firmware file is very important and we need to be 100% certain that the file downloads correctly.  Turn on Airplane Mode on your mobile device so you won’t receive any incoming calls while the firmware is downloading,  or while the Phantom 4 is being updated.

Check Settings After Firmware Update

It is quite possible that the firmware update could put these back to factory settings. This could happen especially if the firmware update was to fix a bug or add new features to the  IMU, Gyro stabilization systems, flight controller or other related drone components.
