Forgot user and password help going mad

Kind of hijacking this thread, but the problem for me is that the reset button is NOT working.

Tried to push it for 4, 10, 30, 60 seconds. Tried to force the MBL to do a boot routine (pulled out the ethernet cable and waited 30 mins. then pulled the power cable. plugged both in again). Also tried pushing the reset button during start up. Nothing changes. I even tried lauching the script (reset button script) through SSH. Still no changes. Any idear?
