Although you appear certain, a quick double check for me to be able to visualize, with the micro USB power cable entering from the right-hand side, screen facing up, BTN1 would be upper left or 11 O'Clock position.
'Holding BTN 1 for ten seconds does absolutely nothing'
Is power being applied after the button is being pressed?
I'm reluctant to suggest the following as it is a bandaid to resolving the Hard-Reset process, but re-flashing could be an option.
