Hey guys
New to this forum and firmware reversing in general

I managed to extract the first part of the A119 firmware but sadly IDA Pro 7.0 doesnt manage to analyse it all
Surprisingly - Ghdira analyse it well

My problem with the camera is a flag that sometimes prevent the camera from booting and force me to click the power button for the camera to boot
My goal is to find the condition and patch it to always boot

For start I would like to be able to work with IDA - if anyone knows whats the problem

Thanks :)

Maybe it's because the car cuts the power to the cigarette port when the starter motor is running or the voltage drops. Did you try to use the boot delay menu option?
