well, its really not that hard, i think you are just lazy cos all the information is here that people have told you and your still asking for more information.

I'll put it simply for you,

Type IMEI
Choose country code
Select Dongle V2
If you are unlocking a 3650 or 7650 select type 5
If you are unlocking anything else select type 2

You have to use common sense sometimes, and read what people have said to you
