Purchased Spark Combo from Amazon (DJI Europe) last week, keep getting Activation failed, Invalid device. It shows as connecting to the server before the failure.
When I go back to the home screen it says that it’s been less than 48 hours since I first activated Spark.
Hi. I am sorry that you are having issues with your new DJI Spark. Have you tried to properly activate your DJI Spark? I will be posting the official DJI Tutorial Video on how to activate the DJI Spark.
Hi. I'm very sorry for the inconvenienced that this caused you. May I know what's the make and model of the device are you using right now? Can you try to connect your mobile device to your aircraft? please disregard the remote controller first. Then try to activate it again. After that, forget the aircraft's Wi-Fi and connect your mobile device to the Remote controller's Wi-Fi and do link your RC and AC. For reference, please watch the video tutorial below. If you have further question, please let us know. Thank you.
For linking your RC and AC, please refer to this link.
