Comment(by Quozl):

 Worked fine in Q4B10, but apparently broke some time after that.  I've
 reproduced the flicker during write on Q4C04ja.

 Note that the test case did not involve holding the button down.  That was
 intentional.  It is sufficient to prove that the LED does not flicker,
 since the EC always flickers the LED on a power button press if the EC is
 operating.  You should not have proceeded having observed the LED flicker.

 (Unrelated to the ticket, it is likely that CForth is intact, and so
 debricking might only require serial port and rotate button on power up.)
