    Default Trouble loading Files

    I have been trying to load a stock file back on a truck that we have previously tuned. It keeps throwing boot loader errors and then says its not lisc to my controller. Im the only one that has ever touched this truck. I have loaded the latest updates.

    Any ideas as what could be the problem?

    Thanks

    Are you trying to flash using which one of these:
    - V7 tunetool
    - V8 S&T
    - V2 BBx

    Which year/model/vehicle...?

    What:
    - V7 build version...?
    - V8 build version...?
    - V2 firmware version...?

    Yes. I have tried flashing the stock file back in using both. I clicked the both that says something like it will take longer to load but it still doesnt work. It pops up saying the truck is not lisc to my controller. My controller is the only one ever hooked to this truck!

    Thanks for your interest in helping with this. I really need to get this resolved! Luckily my customer has been very patient during this!

    When it fails trying to flash the original file (that you read out) back into the PCM using V7, copy the text box and paste it here in this thread.

    I found the notes where I had written it down.

    Bootloader Rejected
    Reason: Controller has returned to normal operation. Please retry the operation.

    After retrying,

    Data tranfer was interupted.
    Please wait 15 seconds before retrying the operation.
    If you're experiencing difficulty reflashing the ecm try unchecking the use High speed check box.

    I think when I tried it in V8 it popped up this warning message.
    E54 Full Flash Warning

    If a full flash procedure fails to complete DO NOT remove power from E54 pcm
    To recover full flash the pcm using 7.5 pass thru flash software.

    Hope this helps!

    Thanks again!
