Here are the steps you need to take to get the unlock code.
Take out the battery and look for the MEID Number. It's a 14 digit hexadecimal number that contains some letters. Write down this number exactly. Now you need to download a
Hash Calculator and install it on your computer http://www.slavasoft.com/hashcalc/
Run the program and set the data format to Hex string and make sure there is a tic in the SHA1 Box. Type in your MEID EXACTLY as it appeared on the label behind the battery.
Now click calculate. Write down the last 6 digits of the number that appears in the SHA1 box, there may be some letters. Now launch the calculator that comes with windows.
Click on veiw and select scientific. Now select the HEX option and qword. Now input the number 80 then the 6 digits you write down exactly as they appeared in the SHA1 box on
the hash calc program. Now click the decimal button. Input the last 4 digits into your phone that appear in the box, this is your lock code. Now go to the phone settings and
change it back to nam1 and auto, do not go through the activation procedure unless you know what you are doing. The phone should reboot. Nothing is deleted or changed

The password is usually the last 4 digits of your phone number. Does that unlock it?

I recently switched my NAM for NAM1 to NAM2 at first everything was fine it rebooted and everything but at start up it asked me for a four digit unlock code i was like what the heck i dont have an unlock...


the default is always one of these code try them all the last four digits of the phonenumber last programmed in the phone aka your number or 9999,1234,4321,0000,1111 if none of those work you can go the retail store for a flash they hook it to the computer and push software to the phone to correct the issue it takes five mins and its free its a common issue for them to correct if you change your lock code from the default in the future always set up a dummy contact with it in there so that you can easily look it up also please vote for me I'm trying to work my way up to expert level and I cant without your vote please

Switched to NAM2 and do not know the lock code.


Dial *22899 and press SEND to program the phone.
after it has finished downloading the programming information, the phone will reset.
The Lock code will now be set to the last 4 digits of your phone number.
when you have finished, be sure to switch back to NAM1 and dial *22899 again to re-program it.

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
