    Default cos help

    I'm trying to build a cos for a boosted 6.0. I have read the file and I don't have an option for a cos. do I have to perform a full flash before this will become available. I'm using a operating system that is shown in the tutorial to have a supported cos.

    Which OS is the file you read...?

    No... the COS file matching your OS would already exist in the Custom OS folder.

    What V7 software build are you running...?

    The flash having failed is indicating to you that it may be incomplete.

    You're not doing it right...

    if you don't have a COS that matches the original OS, then after you full flash the COS, you won't be able to cal flash from the original OS (since the base OS id's will be different).

    12212156 os and tried using (trying to recall but I think it is) cos 02020003 and 05. I am running v7.5.7 software.. I found the cos in the tutorial that corresponds with my os. not sure what is going wrong.

    If your original OS is 12212156, then you would first read it out and save it to a file, then you would full flash 02020003, and then cal flash from saved file...

    is this what you did...?

    If it's not going right, then full flash the 12212156 file and start again.

    that's was what i had done.

    tried again tonight.

    i started from the 12212156 cal full flashed(not problems) then full flashed 02020003 and the flash gets almost the end and fails. if any of my values were out of range would this have an effect on the cos flash? i ran a flash simulation of the cos and it failed the same way.

    it is shown in red 20:24:12:661 unknown reply from bootloader: $fe

    Post a screenshot.

    When you full flash the COS, it is an "empty" OS, you then have to cal flash from the 12212156 file to populate the tables.
