If you are trying to flash Mavic 2 with NLD after you've upgraded with DJI assistant, you won't be able to flash it with NLD. So in other words, if your Mavic 2 has the latest firmware upgraded with DJI Assistant or app, you can't do it.
The fact is that I did not update the firmware via Assist.. But there was an update installed from the app... At the same time, NLD writes that firmware 400, that is quite suitable!
The author of the software should say whether there is a chance to break the tegu upgrade. If so, at what time? How not to refund for non-working software?
Yes, I know, on the day I bought the program I did 7/26/19 upgrade. Bad luck. That's why I immediately wrote to the author hoping for a reaction. I didn't get a clear answer whether the program will work or not in the next upgrade. It's not about money either! I only expect an answer - is there a chance for a working patch ?!
