There is also a free and open source tool for EDL on github:
But to properly use that we need a corresponding loader file which I couldn’t find so far.
The FP3 can be switched to EDL mode by powering it off and then keeping both volume buttons pressed while connecting the cable. (screen will stay black)
It is then detected when running edl.py. It prints some device info and complains about missing loader file. Then any further executions of edl.py result in “unknown sahara mode” until the phone is power cycled. (press the power button very long, power off again and redo the volume keys + cable)
