firmware cache from DJI Assistant.app as extracted from dji_system.bin files, and collected by end users. Accompanying .bin files can be located here: https://github.com/MAVProxyUser/dji_system.bin
Individual .fw.sig files can be thought of as individual sections or modules within the entire firmware.
The naming convention is as follows:
<model>_<module>_<version>_<date>.fw.sig
The 1st value in the file name is the Model.
The 2nd value is what the module effects.
The following files are all related to "Camera Upgrade" for the respective model
because the second number value 0100 is the Module #.
- wm220_0100_v02.00.55.69_20161215.pro.fw.sig
- wm330_0100_v01.19.52.66_20160623.fw.sig
- wm331_0100_v01.04.15.46_20170317.pro.fw.sig
- etc.
| Number (first value in file name) = Model |
|---|
| wm100 = Spark |
| wm220 = Mavic |
| wm220_gl = Goggles |
| GL200A = GL200A # Mavic Controller |

| wm331 = P4P |
| wm620 = Inspire2 |

https://github.com/fvantienen/dji_rev - This repository contains tools for reverse engineering DJI product firmware images.
https://github.com/Bin4ry/deejayeye-modder - APK "tweaks" for settings & "mods" for additional / altered functionality
https://github.com/hdnes/pyduml - Assistant-less firmware pushes and DUMLHacks referred to as DUMBHerring when used with "fireworks.tar" from RedHerring. DJI silently changes Assistant? great... we will just stop using it.
https://github.com/MAVProxyUser/P0VsRedHerring - RedHerring, aka "July 4th Independence Day exploit", "FTPD directory transversal 0day", etc. (Requires Assistant). We all needed a public root exploit... why not burn some 0day?
https://github.com/MAVProxyUser/dji_system.bin - Current Archive of dji_system.bin files that compose firmware updates referenced by MD5 sum. These can be used to upgrade and downgrade, and root your I2, P4, Mavic, Spark, Goggles, and Mavic RC to your hearts content. (Use with pyduml or DUMLDore)
https://github.com/MAVProxyUser/firm_cache - Extracted contents of dji_system.bin, in the future will be used to mix and match pieces of firmware for custom upgrade files. This repo was previously private... it is now open.
https://github.com/MAVProxyUser/DUMLrub - Ruby port of PyDUML, and firmware cherry picking tool. Allows rolling of custom firmware images.
https://github.com/jezzab/DUMLdore - Even windows users need some love, so DUMLDore was created to help archive, and flash dji_system.bin files on windows platforms.
https://github.com/MAVProxyUser/DJI_ftpd_aes_unscramble - DJI has modified the GPL Busybox ftpd on Mavic, Spark, & Inspire 2 to include AES scrambling of downloaded files... this tool will reverse the scrambling
