You want to double check about that hard reset. I think you've probably only done a soft reset. A hard reset will reset the machine back and wipe off ALL your data and settings, including the password.
The front screen password of which you are referring to NOT any of the ones you have listed, but instead it is something you would have set when setting up the device.
Have a try with some of your usual passwords
HTC Kaiser (KAIS130), HTC Tytn2, Motorola Defy, Samsung Galaxy Grand (suicided both sim slots within 4 months of gentle use), Motorola Defy Plus, Moto G....
