MY GUESS is that I have found why..
The password is stored in the firware and if you flash the drive the password is GONE. EVERYTHING I have seen says that the password is in firmware. I just wish the "downgrade" on that site above worked for me.
Now,
I think that with the flashing tool you could backup your current bios. If thats the case, then I just need a fellow to backup his firmware and share the love. 😉
