  • 70mai A500 / Pro Plus (Hi3556V100+IMX335) dashcam hacks.

    70mai A500 dash camera uses YAFFS2 filesystem to store some important data in flash memory. Other HiSilicon devices usually use UBIFS, JFFS2, SQUASHFS and EXT4 filesystem.

    Linux tools for unpacking and repacking YAFFS2 filesystem image:
    DOWNLOAD YAFFS2TOOLS

    Usage:
    To unpack: Put your appfs.yaffs to the folder with unpacked files. Run unpack.sh. New appfs folder with unpacked files will appear.
    To repack: Edit the appfs folder according to your needs (like replacing some voice audio files or UI text files). Run repack.sh and get the appfs_rep.yaffs file.

    Compiled from sources from here and HiSilicon SDK.

        A500s is built on a brand new hardware platform and I don't have this device on my hands to try repacking any custom firmwares at the moment.

        Mee too interested on 70mai a500s for time lapse parking mode.
        Can i patch and modify sensitivity on parking mode because my camera is on high sensitivity on parking mode and does not start when i hit the car, close the door, hit the tires, tap the windshield?
        The car need to be hit by a truck to start the recording or hit the camera hard.
