huntcve / exploit Goto Github PK

I wonder how could I adapt this CVE to get it working on my specific device? I'm running it on Docomo Fujitsu Arrows NX F-01F [ Android 4.4.2, build # V10R22A (kernel version 3.4.0), ARMv7 arch (armv7l, armeabi-v7a) ]. When I open the mp4 crafted by the script, the gallery crashes and restarts. But there's no back-shell connection to my server. My assumption is that my phone is vulnerable but the code does not match it. What things should I alter there?

Hi Seven, my name is Felipe. I'm a student from brazil,  currently studying cibernetics. First of all, i hope you are doing well with this covid situation.I'm writing to you to talk about the article that you made http://huntcve.github.io/2015/12/16/debug-stagefright-exploit/ explaining how to solve the problems with the exploit made by jduck. Following your steps i was able to solving some problems, but i got stuck with the debug. I don't have so much experience in this subject yet, so i really don't know what to do. For example, i do not got it how you defined that breakpoints address to start the debugging.
I wonder if you could explain me how to solve this issues, in a more detail way. This is a work that i'm doing for my graduation, will be really useful for me, thanks in advance
Greetings from Brazil !
