Ignore all of these things and wait for the "Upgrade Successful" message to appear in the DJI GO 4 app. This process could take up to 15 minutes to complete. 13) Restart your Phantom when the "Upgrade Complete" message is displayed. ───────────────────────────────────────────────────────── Install the firmware on your remote controller using the DJI GO 4 app Note: Some firmware updates do not include an update for the remote controller. If that's the case, you an skip to step #21 below. 14) Ensure your remote controller has at least 50% battery level (at least two white lights are lit up at the bottom of the remote controller).

If you only have one battery, then skip to step #26 below. If you have more than one battery, then repeat the following steps for each additional battery. 21) Turn off your Phantom. 22) Insert the next Phantom battery into your Phantom and power it on. To power on the battery, press and release the battery button quickly -- and, then immediately press and hold it in for 2 seconds. 23) Wait at the main screen of the DJI GO 4 app for the "Inconsistent Firmware Found" message to appear. Note: If this message does not appear within a few minutes, then your battery most likely already has the latest firmware installed on it or the current firmware does not include a battery update. Go back to step #21 above if you have additional spare batteries. 24) Slide the "Slide to Update" slider to the right to start the firmware update process. A progress bar will be displayed at the top of the DJI GO 4 app while the firmware is being installed. 25) An "Update Complete" message will be displayed when the firmware has been installed. Click the "Complete" button. 26) If you have additional batteries, then go back to step #21 above and repeat these steps with the next battery. ───────────────────────────────────────────────────────── Confirm the firmware installed correctly 27) When your remote controller reconnects to the DJI GO 4 app and your Phantom, the Overall Status should show "Normal (Latest firmware)". 28) Look in the "General Settings" --> "About" section of DJI GO 4 to verify you see the firmware versions you just installed. ───────────────────────────────────────────────────────── Check and/or restore all settings in the DJI GO app 29) Verify that all of your previous settings are still set in the DJI GO 4 app. You'll want to do this while your Phantom is turned on (with the props off) and your remote controller is connected to the DJI GO 4 app via your mobile device. This is important since many of the settings are saved on the Phantom itself. ───────────────────────────────────────────────────────── Recalibrate 30) Do the following calibrations from within the DJI GO 4 application: Calibrate the IMU (on a completely level surface) Calibrate the gimbal Calibrate the compass (outside away from anything metallic) Calibrate the remote controller Note: These calibrations are recommended, but not required.
