install samsung usb drivers on your computer,then install samsung pst, download the .dll for r810 metro and read the phone with samsung pst it will give you the security code. cdma workshop will also give you a security code,but alot of the time it will be wrong for samsungs,but pst will be right every time.or just take it to a store that flashes and have them read it for you, they might charge ya 5 or 10 bucks but it might be worth it if you dont want to install and use/learn to use some phone softwares. good luck.
