Help Help with a Hard Reset/Hardware Reset

[KallyKatt]

So I bought this model a while ago, but haven't used it in a while, so I plan on selling it. However I want to restore the device to it's factory settings, but I don't know the 9-pin unlock pattern to do this. I've scoured the Internet for any combinations I can use, but I can't find anything that works.

I really need help here to get it reset, thank you.
