====== Phantom 3 and Inspire 1 Modification Overview ======

This guide explains how to modify Phantom 3 and Inspire 1 flight controller parameters running ANY firmware version. 

NOTE: THIS IS FOR PRO USERS, YOU HAVE TO KNOW WHAT YOU ARE DOING! I'M NOT RESPONSIBLE FOR ANYTHING.

These instructions apply to any firmware version as of January 2018; the keys were found, we are good to go on all versions.

====== How to videos ======
The following how to video shows the process end to end. Watch this before doing any of this!

====== Toolset ======
Make sure to review this GitHub with more info: https://github.com/o-gs/dji-firmware-tools

  - Download [[https://github.com/o-gs/dji-firmware-tools/raw/master/dji_xv4_fwcon.py|dji_xv4_fwcon.py]]
  - Download [[https://github.com/o-gs/dji-firmware-tools/raw/master/dji_flyc_param_ed.py|dji_flyc_param_ed.py]]
  - Download [[https://www.python.org/downloads|Python 3]]
  - Download your [[http://jogjasky.com/go-download|Firmware of choice]]

Put the PY files and the firmware bin file in same folder, such as C:\P3

Install Python 3, reboot if required. Make sure to SET PATH for Python. If you don't know what this means, google it. 

[[howto:P3FWTOOLUSE|Detailed Usage instructions for the two Python Tools, dji_xv4_fwcon and dji_flyc_param_ed]]


====== Detailed Steps ======

==== 1. Extract the flight controller Module ==== 

  * Put "dji_flyc_param_ed.py", "ddji_xv4_fwcon.py" and "P3X_FW_V01.07.0060.bin" into one folder such as C:\p3
  * Open a command prompt on Windows
 

    Start->Run->cmd

  * Navigate to this folder C:\P3

    cd\p3
    PRESS ENTER


  * Type into cmd  (Note: Replace "P3X_FW_V01.07.0060.bin" below with the fw version you are using.

    dji_xv4_fwcon.py -vv -x -p P3X_FW_V01.07.0060.bin
    PRESS ENTER
 
  * If you receive the following message:
    ModuleNotFoundError: No module named 'Crypto' 
  * That means there is a module missing in the Python 3.6.x installation.
  * If you do not get the error skip down to "The firmware will extract..." below.

  * To get the needed Module open a cmd prompt as administrator.   
  -   (win 10) Take the cursor to the bottom left corner and right-click to open the WinX menu. 
  -   Select "Command Prompt (Admin)" to open an elevated command prompt.  
  -   Type into cmd

    python -m pip install pycryptodome
    PRESS ENTER

  * Wait for the process to finish download and installing pycryptodome module
  * Now repeat this step
  * Type into cmd

    dji_xv4_fwcon.py -vv -x -p P3X_FW_V01.07.0060.bin
    PRESS ENTER

  * The firmware will extract and various modules will show in that folder different modules. The important module is P3X_FW_V01.07.0060_m0306.bin
  * Type into cmd

    dji_flyc_param_ed.py -vv -x -m P3X_FW_V01.07.0060_m0306.bin
    PRESS ENTER
  
This will extract the firmware and the flight controller firmware module.  


==== 2. Edit  the flight controller Module ==== 

  * Open the flyc_param_infos file in Notepad, Notepad++ or your favorite text editor
  * Locate the parameter you want to find, change the value noted in the table below.

   Example
   g_config.advanced_function.height_limit_enabled_0
   Change the MinValue and MaxValue = 2

  * Be careful to only edit the parameters you are familliar with!
  * Save the file

==== 3. Recompile the 306 flight controller module ==== 
  * Type into cmd 

   dji_flyc_param_ed.py -vv -u -m P3X_FW_V01.07.0060_m0306.bin

  * After this command runs, it will compile the parameters back into the P3X_FW_V01.07.0060_m0306.bin file. 
  * Now, you need to rename the file before loading on the aircraft. Rename it to "PMCAPPFw3.bin" for p3 and "INMCAPPFw1.bin" for inspire 1 (no quotes).


====  4. Install the modded file on your Phantom ==== 
  * To install the file on your aircraft, copy the PMCAPPFw3.bin or INMCAPPFw1.bin file to a formatted micro-SD card
  * Insert SD card into aircraft, power on. If the firmware update does not start, you can force it by holding the button on the side of the VPS.
  * The file will be flashed and the edited parameters will be applied.
  * The flashing progress takes about 5-10 minutes.
  * After flashing is complete the file on SD card " PMCAPPFw3.bin " will be automatically renamed to " PMCAPPFw3_updated.bin". Delete this fie, then fly your aircraft
  * NOTE: The changes work in the simulator as well, test there first! 

====== Important Parameters ======
These are the important parameters you may want to modify to change the flight characteristics. These may change a tad from p3s to p3a to p3p to Inpsire. The proposed below are from p3a 1.7.

I removed the g_config from the prefix to make the table fit better :)

These parameters are intended to be informational and as guidelines. You can change certain ones like speed +/- from what is posted above. Please fly safe and within the limits of the aircraft and yourself.
