hello and good morning after a month of searching and help from the forums (Hak5 ) and many other . i was able to locate the Firmware location on Assistance 2. below you can see the path for OSX and MS .now the file are in a fw.sig. format. so since DJI is pulled the firmware now you can archive a so far i have the current ver (V01.04.0602) and ver V01.03.0509 for the P4Pro

on OSX /Applications/Assistant.app/Contents/MacOS/Data/firm_cache

or on Windows C:\Program Files (x86)\DJI Product\DJI Assistant 2\Assistant\Data\firm_cache

they look something like this
