I have just upgraded the firmware and the aircraft is now locked. The DJI Assist (latest version) does not show an unlock button and I am somewhat frustrated now!

Anyone have any suggestions or have the same issue?

Could you verify the Assistant 2 version you have and OS you're running? What firmware did you just upgrade to?

Hi

Version 1.1.0-2

IOS - 10.3.2.

Firmware - 1.00.01.20

Maybe you already tested, but when you are connected to the aircraft through DJI Assistant, see to it that you are also connected to Internet. If you are, try to log out from the app and then log in again and see if it helps.

We are having the same issue with our M600. We're running the same firmware on two M600 drones, one works, the other doesn't.

Seems a very strange inconstancy in the software. We're in touch with DJI but as yet no solution. Have you had any luck?

Yes we have the same issue with our drone in South Africa. Have you found a solution?

Hi, same problem here in Japan.
DJI GO Version 1.1.0-2 or 1.0.9.20
IOS - 10.3.2. or 10.3.3
Firmware - 1.00.01.20
It seems to be a buggy firmware but problem is you can't downgrade which is the only solution in this case.

Well it seems that opening DJI GO 4 first and following the rerouting to DJI GO will unlock the aircraft! You need to be connected to Internet and aircraft on but all applis down before starting.
I hope it will work for you.

Just got this.....

Dear Gerry,

Sorry for our latest APP.
You have to uninstall the DJI GO then download the DJI GO4 and open it.
After that Uninstall the DJI GO4 and Re-install the DJI GO, This problem will be solved
Really sorry for the inconvenience brings to you 

Kind regards

My Issue has been fixed. It cause by the firmware of camera module is old, but dji go app show error "Aircraft is force locked" instead of "Need to Upgrade Camera Firmware".
