Thread OP

DJI Mavic Mini FCC mod

1. format sd card with ExFat
2. create *.txt file called ncdo.txt
3. enter into ncdo.txt file:

66 63 63 for 1000mW mode
6d 69 64 for 500mW mode

followed by SHA256 value of your Mavic Mini serial number.
You can use online SHA256 generator to turn your serial number into SHA256 hash:

So for example for 1000mW mode with serial number AC8493299 enter:

66 63 63 f768e57e278014775ad8f20f7a225517529a69a45bbd078028 5a26d84723680a

4. hit save
5. copy the ncdo.txt file to the microSD card
6. make sure Mavic Mini is powered off and insert microSD card
7. power on Mavic Mini
8. Mavic Mini is in high power mode immediately. No need to change any other settings.

Awesome man, it works.

I can not record photos or videos to SD card though, it constantly says "NO SD card".

maybe try to make on card small partition in ExFat, and other partition in normal file system. Maybe this will work?

Doesn't work with 2 partition.
It does not recognize the sd card then.

@gorro, so i assume the file not working if sd have only fat32? its working only with exFat?

Also have you tried turning on drone with mod, then pull out exfat card, and then plug in right one with fat32? Is this work?

Can someone also just confirm that this mod is reversible. As in when I stick my normal micro SD card in it'll revert back to its prior mode.

Yes, removing the SD card will bring back CE.

I was unable to get this to work as I got a SD CARD FILE SYSTEM error when I tried.
Seems that this might not work.

I did ALL steps.

Something very fishy here. @gorro's photo in post #2 is fake. It comes from a video: in which 19dBi antennas are used with 2W transceivers to get this range. The setup is explained in another video here:
