How to Downgrade the Controller firmware

The Elios and Elios 2 drones use DJI Lightbridge 2 control units, and as such require the DJI GO app to be used for some advanced operations such as:

Flyability drones require firmware v1.2.10 to be installed on the control unit, it is therefore imperative that you do not let the DJI GO app perform a firmware update, even if it shows a flashing banner:

Performing this anyway will install version 1.2.40 or higher, leaving the drone unable to connect to the controller.

HOW TO DOWNGRADE

The controller must be downgraded by following this procedure:

  1. Connect the remote to the device with the DJI GO (before P4) app
  2. From the "Connect your DJI device" main screen, press and hold the menu icon in the top right corner of the screen for 2 to 3 seconds
  3. Select version 1.2.10 from the drop-down menu and press start
