This document describes how to use DUMLRacer to remove the restriction put in place my DJI to prevent owners from downgrading from Mavic FW 1.04.0100, as well as enabled adb as the root user.

You can run DUMLRacer manually (see the readme in git) or you can use it in DUMLDore 2.11 or higher automatically.

https://github.com/CunningLogic/DUMLRacer Go to releases and get the lates DUMLRacer.jar and put it in the same folder.

It is a commandline program, you run it in java. If on linux or osx, open terminal if on windows open command prompt then java -jar DUMLRacer.jar <mode>

Modes are AC, RC or GL

AC - aircraft RC - remote GL - Goggles

After it is done, it enables root and downgrade. Jezzab has implemented the exploit into DUMLdore, but I'm not sure if he added the latest version. If DUMLdore does what you want, then use it. Both races need to be won, you can check with “adb shell”. The root is most reliable on the 01.04.0100, less so on others. It may take a few minutes to start as well after reboot.

It is “perm”, it can be removed by doing:

adb shell mount -o remount,rw /vendor rm /vendor/bin/* reboot
