Hi folks, I have, for the first time ever, tried to flash the EC 
firmware on a Google Grunt EVT platform.  I have succeeded in the past 
flashing the coreboot image but the command sequence to flash the EC is 
somewhat different.  Here is the output I see:

    DO NOT REBOOT OR POWEROFF!
    FAILED

I did not reboot or poweroff, but it did finally shut down (at least all 
the LEDs went off).

What do you recommentd next?

Thanks,
