If you have already used all 3 attempts to unlock via keypad, but you have unlock codes from your carrier, you can use the program to input the codes.
In "c:\bb5_unlocker\psw" create a text file "aaaaaaaaaaaaaaa_BB5.psw" where is "aaaaaaaaaaaaaaa" enter your phones IMEI
Then in that created file enter in "#pw+bbbbbbbbbbbbbbb+c#" where is "bbbbbbbbbbbbbbb" is the unlock codes and where is "c" enter your logs level number (1-7).
Save the file
Use "SP UNLOCK" function
