Remove Unlock Pattern in Motorola Razr i?

I bought a Motorola Razr i in the web but It turns out that the phone has an unlock pattern and now I can't contact the seller.

I really dont know If im doing well the process so I need someone to help me with specific instrucions of how to do this or with another solution. Thanks.
