Hello! I have bought your product in Russia, in the store http://gp-market.ru/
I charged the batteries, and updated the firmware (copter and remote control).
I studied the instructions and your video tutorials.
My copter does not work. In DJI go message - "main controller data error" and Overal status "data recorder error",
"data logger error".LED - red. It's my fault? Or my copter is not working? Help me please. version app-2.8.1
aircravt v 01.-1.0301 ,controller v 1.6.0   serial number 07JDD3900101LW.
P.S.Sorry for my bad English.

Thank you in advance!

Hello Oleg, does this issue come up right after firmware upgrading? Did the drone crash before?

DJI-Paladin  Thank you !
No crash.The drone of the box, the first run.The engines would not start.Yes, after firmware upgrading.

I rolled away the previous firmware - did not help.
