How to root your DJI Mavic Pro, Phantom 4 and Inspire 2 using DUMLRacer and completely remove NFZ


#21

When Go4 4.2.16 was released, the release notes made me fear this could be DJI bolting things down … so rolled back the app to 4.2.14.

Hi , again, can’t seem able to download the Dji assistant 2v1.1.2?
Outdoor you point me in the right direction please.

Download from here @jimvfrmoto750 - https://greyarro.ws/t/useful-downloads/1798/2

Hi, I’m also having the “No device found” problem on both my drones :frowning:
Under what category in Device Manager should the drones be located, and what name should it be?


#25

I want to say a BIG thank you. Using your utility and information I was able to successfully remove the NFZ file. After performing all of your suggested steps I still had some issues. I am now running the latest firmware on both controller and drone and have no NFZ issues.

Hi @Mizzou and welcome to Grey Arrows!

Thanks for taking the time to sign up and reply, I’m glad the guide helped :smiley:

It’s 9+ months old now though so it’s possible some things have changed re later firmwares.

Can you share your experiences of the issues you encountered? :+1:t2:


#27

Be glad to. I first went directly by your instructions. No luck. After getting the files deleted from the drone I did a restore to factory setting on both the controller and the drone. Still no luck. I basically had given up. So I decided to upgrade firmware to latest version on both controller and drone. And I’ll be damned - problem solved.


#28

Glad it was an easy fix - thanks for the update!

Do you know if this method of removing NFZs is Litchi friendly?

Whilst I went the other method, and turned NFZs off … which works fine with Go4 … Litchi won’t play ball in my garden.

I’m guessing Litchi has it’s own NFZs … to prevent a mission being initiated that flies into one (never tried to see what happens with that one) … and ignores the onboard NFZ info.

Of course - even with Go4, the Controller still mentions that I’m in an NFZ … but I could still fly.


#30

This method removes the NFZ database in its entirety. So assuming Litchi doesn’t run its own NFZ database in the app, then you’ll never see so much as a warning :+1:t2:

I’m not up to speed with Litch and a quick Google didn’t reveal anything but it doesn’t look like it has a NFZ database? I certainly don’t recall ever being asked to update one anyway?

This method will also prevent your controller thinking it’s in an NFZ too :slightly_smiling_face:


#31

It seemed strange that Go4 would happily fly in the NFZ, but Litchi wouldn’t … which suggests Litchi is getting it’s information a different way.


#32

Ahh … perhaps this is my answer …

I wonder how they are supporting it? Their own database, I’d assume.
Might roll back to the previous version and see what changes.

Edit
Other than I’m on Android … and that doesn’t seem to feature in their android release info.
