Forgot security code

Hello,
i have nokia 7610 old model. and now i forgot my security code and when i want to reset my factory setting it asked me to enter the security code and report the code error
so how can i change the security code for my phone and how can i reset my settings

i also tried the master code generator
my imei no is ...352273015024828
and the master code is 1312362503

is there any other software which could help me to unlock my phone please specify if any.?
