I got a Spark as a Christmas gift.
Charged the battery and did all the necessary steps- updated to the newest firmware as instructed by DJI support.

No luck for my brand new Spark, I was very excited to have the DJI product but now dont know what to do with this Spark.
Not sure about the exchange policy in Bestbuy Canada- it says unopened box only.

Hope DJI can help me with this issue so I can have atleast a good new year to come!!!

more info: fresh out of the box and no air flight time Spark-

Here is another thread with same problem: https://forum.dji.com/thread-124458-1-6.html
The reason was that Spark was not connected with the RC. How to do it you can read in the Quick Start Guide or in the video here below:

Thank you Wachtberger!
hope it works for me.

Hi, sir. Did you solve the problem? I would recommend you connect your spark with phone and  enter DJI GO 4 and see the error message in the app. Please keep us updated, hope it can works.

Solid red rear LED critical error, Yes connect to your device with DJI GO 4 app to understand the error message. Secondly there are youtube videos to understand the LED indicators what they are telling you or just have to go through the manual.
