+This document describes how to use [[https://github.com/CunningLogic/DUMLRacer|DUMLRacer]] to remove the restrictions introduced by DJI to prevent owners from downgrading from Mavic FW 1.04.0100. DUMLRacer also allows you to enable adb as the root user.
+You can run DUMLRacer manually (see the readme in git) or you can use it in [[https://dji.retroroms.info/howto/dumldore|DUMLDore 2.11]] or higher for point-and-click usage. However, Dumldore does not leave permanent root like DumlRacer.
+===== Download =====
+Get the latest JAR file from [[https://github.com/CunningLogic/DUMLRacer/releases|Github]] and put it somewhere on your computer.
+===== Execute =====
+DUMLRacer is a commandline Java program. You first need to open a shell window
+  * MAC: Open terminal - and cd to the directory where you downloaded DUMLRacer
+  * Windows: Open a command prompt, and cd to the directory where you downloaded DUMLRacer
+  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 downgrades. Jezzab has implemented this exploit into DUMLdore. If DUMLdore does what you want, then use it. NOTE however, DUMLDore does NOT apply the root part of the JCase/DUMLRacer exploit
+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.
+Root access is permanent. It can be removed by doing:
+  adb shell
+and then...
+  mount -o remount,rw /vendor
+  rm /vendor/bin/*
+  reboot
+**Want to remove that pesky 905 NFZ?**
+from ADB Shell
+  mount -o remount,rw /amt
+  cd amt
+  rm -r nfz
+Also check the data/upgrade/backup dir and delete the 905 backup module
