Factory Reset - Fails

[CJVann]

I've tried repeatedly to factory reset my EISY with the 10-presses of the power button.  I hooked it up to a monitor, and I can see that the 10-button presses does nothing at all.  It just sits at the Login prompt.  Any advice?  I purchased a new home and need to blow away all configuration and devices from the old house.  I also tried the old ISY procedure by holding the back reset button in with a pin for >30 seconds.  That turned the button red and wouldn't turn back on again until I unplugged it.

After it boots back up, it still remembers the old username/password and all devices are still present.
