    Hi

    You can export the firmware file from a good unit and import back to the bad unit.

    Hi

    If the device is stuck at ROM mode, you can not program with tifsp.

    you have to reprogram the firmware to bring the device out of ROM first

    Do you have a firmware file? 

    Regards

    hi Yihe,

    yes we did dump out the firmware from device before he go into ROM mode.

    we program the firmware (hex) to the device, and cycle power.

    once cycle power, it go into ROM mode again.

    Thanks,

    Janice
