Cant Downgrade Firmware from 01.000.0300 to 01.000.0100

I downgraded the firmware by DJI software to version 01.000.0300, bought the license and then by NDL Mod Client 2.0.1.25 I tried to downgrade to version 01.000.0100 but it stopped at 15% (Checking firmware modules md5) and does nothing else.

I need a solution because I bought the license and I can't put it in the version for removing the NFZ.

We are a drone maintenance company and we have already purchased 8 licenses from you. I need an urgent solution because the customer is in need of the equipment.

Hi Alexsandro,

What drone do you have?

My client sent me a Mavic 2 Pro to remove the NFZ. I bought the license to do the service, in the same way that I always do with Mavic Pro, but this time I couldn't do it.
