and change software in this phone after recovery mode

hope this help

I bought this phone from someone and they didn't factory reset the phone and I can't get in touch with them to do what they need to do. How do I factory reset the phone without having to put a pin #. I've tried doing the hard set that is said to do and it won't reset it. So what do I do?
