  • Modify automatic boot flag of A119 Dash camera

    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
    Would like to know why IDA fails like that - IDA never failed my before

    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

    It could be in loader not in firmware itself.

      Well I can actually modify the loader as well... but the loader code is even worse

        Do you have any idea what could be wrong in your case? Insufficient voltage due to bad cable or PSU?
