Replace last name in Facebook (Have hit the limits)

I saw you guys with a problem to change name after limits..
In this process basically you will be going to deactivate your account,, It is totally secure..,
And you have not to deactivate the account in real.., You are going to secure it
Just follow the easy steps below : 

1. Change your Facebook name to your previous or first name (on the list) enter the password => apply
2. Go to security tab => Deactive your account then select my account is hacked => select my account is hacked for answer/reason
3. Follow the next step then change your password. Next you will find the option to change your name to new name.
