    Likely your suspicion is valid.

    It, like regions 41 and 154 before, contains UnitId and references to maps installed in the device.
    Is rgn13 encrypted like the NV region of modern automotive devices and did you need to de-crypt to see UID etc.?

    No, region 13 is not encrypted.

    Hi!

    Is there way to backup regions for Alpha 300i?

    How to extract Ldr.bin file from software GUPDATE.GSP file?

    HWID is 4335 for K version.

    If you donít figure it out, send me the GUPDATE .gcd file and Iíll prepare it.

    @IZK

    Ldr.bin from GSP file, not from GCD.
