Will not Hard Reset! HELP

Every time I search for this phone Samsung Galaxy W t679m, I can find the Galaxy Exhibit, but it is not an exhibit, it doesn't say exhibit on the opening screen; it says Samsung Galaxy W.

I need to perform a Hard Reset in order to buypass the lock code; I know holding down Power + Volume Down = Custom OS, but when I hold Power + Volume Up it will show the 'Android Out of The Box' picture, but it will stay like that until it shuts itself off. I have no other buttons on the phone except the touch screen ones that only work when it is on. If I press the menu button (three horizontal lines on the very left) on the touch screen, it will display yellow words over the Android, it says "Rebooting..." at the bottom, and it just shuts off. Am I doing it wrong?

How do I Hard Reset this thing! Thanks in advance!
