I'm having the same problem here,
https://forum.dji.com/thread-128849-1-1.html

Never crashed before, took it out today and had compass error issues for the first time. I already tried moving to different areas and tried areas that I flew before and the problems still occur.
Why would my Drone all of the sudden stop working!? I got the latest firmware for the Phone App and version V01.00.0900 for the drone.

I don't see the latest firmware for the spark (V01.00.0100) on the Assistant Go desktop App.
Is the problem happening because the firmware needs to updated? Have anyone flew the spark lately with the V01.00.0900 firmware?
