    Change the keys in bin file

    Is there a way to change the keys in the bin file?

    I've try to change the hex code, but after upload to the deco it gives error0

    Thanks

    I extracted from the latest bin, ED2100-19-04.bin, the .stk file, so with Caslink, that you find in Edison Tools, edit what you want and put the new .stk file in the bin file.

    And if you only replace the stk file, you will not have any err0, because no crc check at that location, at least on Edision 2100FTA firmware

    Regards Hyujin.

    Thanks for replay!

    How do you have extracted the .stk from the bin file?
    Sould't be the same thing, extract change the file a put it again? Or change it on the bin file?

    All the best

    I extracted the .stk file with an Hex Editor, Hex Workshop.

    In Hex Editor Find the string "ILOVEYOU", or in Hex "494C 4F56 4559 4F55", this is the beginning of the .stk file, then select 0x2FF0 bytes, and you have all the file ready to copy to a .stk file.


    You can edit the bin file to correct a key, but remember, only in the stk area.
    That was your problem, when you got err0, you edited a key not in the stk area, and didn't correct the Checksum.

    Theres all you need to know. the RSA key is in the .stk file. Just edit the .stk with Caslink.

    Hi,
    You can do that but CRC have to be corrected or else you will get err0 on boot.
    We need help programming a tool because it's lots of work to do manually.

    Regards.
