    1. Find in navcore.ttpkg Public key. Rename this key to our key.
    2. Make app something like "TCP client/server" for communication with tomtom.
    3 And we can use our public/private key to response with tomtom.
    In this way we can activate our TomTom`s.
    But first we must decompile navcore and look how the communication is crypted and how must look "good response" to activate TomTom

    @pawel_1980
    Good idea, but alas - impossible...
    1 - to imbed smth into *ttpkg - you MUST have PRIVATE TomTom key - else this *ttpkg won't be accepted by Device. And it's impossible, cause PRIVATE can't be on public by no means.
    2 - look #1

    But i think in this way we must go. Find and replace to our new public key and then device will accept cracked *ttpkg

    Yea - most wonderful thing - is to REPLACE original with OUR, this operation requires ORIGINAL PRIVATE key... In software way as we all wanted to - but it's really impossible. If we could know this PRIVATE key - why should we change PRIVATE? Simplest...

    When we will generate new Public key then we will know Private key. Because we will have new Certificate with our keys.And then everything its accepted.
    But first we must know how to replace this in *ttpkg

    I don't think it's impossible problem - if we already can unpack *ttpkg - then we can learn how to repack it. Problem is - no *ttpkg accepted without signing with Private TomTom key. That's the problem. Perhaps this done on the first launch with servise *ttpkg or smth like JTAG, but then - only via signed *ttpkg. It would be very easy, if not check-up of this key would be required... Alas...

    problem is ; all ports are closed by the software
    if we could get strait in , bypassing ports and internet-software , we would not need a key ( except META-key perhaps )

    on the other hand ;
    we need a patched navcore packed it .ttpkg
    as you know ; service-tool installs anything , key or not
    so , if its possible to create .ttpkg , we are in

    and ;
    we also dont have a tool to create META blowfish code ( easyusetool cannot do it , because ID is same as serial )

    I think there may be easier way but require some hardware, unsolder flash, dump tsop, there we can modify everything without worrying about checksums. Put this to flash again. Solder and we have patched tomtom. There is no way to put anything to device normal way without exploit and cracking checksums is not doable in reasonable time. remote SSH exploit wont happend soon. Maybe http but I doubt. Patching flash dumps can be way easier. Device dont have hardware checksum and flash is not protected from dumps. This is simple linux you just run with ssh locked, tty locked.
    Anyone tried this way ?

    Please read attentively my earlier post - it's possible to assemble *.ttpkg, but what we find inside? - Image with our "patched navcore", file "ffiles" with hash sums of Image - well, we can replace them both... but! trouble is - impossible to create file "files.sig" - which created with Private TomTom key.

    wrong - it exists for over 3 years. But it's no use of it till now.
