SOURCE: samsung sch-r410 cell phone

its the last four digits of ur fone number

SOURCE: lock code for nam2 settings

Ok i sent an email to sumsung and i got this response

Thank you for your email. If you switched the NAM to NAM2 you will need to calculate the code. Listed below are the steps on how to do so:
1.Obtain the Hexadecimal ESN of the phone. The ESN should be printed on the sticker on the back of the phone, under the battery. The Hexadecimal ESN is the one with letters and numbers.
2.Open Windows calculator by going to Start -> Run -> type in "calc", then click OK
In the Calculator, click "View" then "Scientific".
3.Click on Hex and type in the Hex ESN
4.Click on Dec for the decimal conversion and use the last four digits for the code on the handset
5.Once the code is entered and the menu can be accessed, switch the NAM to NAM1

You will have to reset your mobile phone back to factory default settings.

BUT FIRST.......................Look up in your phone manual for the code for your phone.
If you have not got it then you will have to get it off the net via the samsung website under ..............................samsung SCH-R631 unlock codes or samsung SCH-R631 factory default settings, you will need to remove your battery and make a note of your serial number and any codes on the reverse of the phone then replace the battery again.
