I'm not sure how there doing it but this guy below has all the .firm builds in his hourly page for B9Sv1.2, if you need them that is its just a shame we could not get your app working!yeah i implemented that -b in my python script but doesn't help apparently the problem is with the framebuffer adress they are integrated in the code so i don't really know how the new firmtool works since the readme.MD is not updated
