I accidentally selected the programming of NAM2 on my samsung freeform and it locked the phone and I don't know the code

Go to the keypad, type #43574357* (this number should work) and select system info, and it will display your nam2 phone number on the first (top) row labeled "MDN." The last four numbers is your passcode.This solution ONLY works if you've accidentally set your phone to NAM2 (which means that you've reprogrammed your phone to a completely different phone number, and if you've set up a passcode, that too is changed). Once you've found out your new number and passcode, you are not yet finished, because your phone is still programmed to NAM2. To fix that, you must go to your "Phone settings" and find "NAM select." Then you select NAM1 (and your phone will restart again and prompt you with your OLD passcode, if you set up one). Your phone is now fully functioning again!

Is your mobile is SCH-r360 or r360 Messenger or r360
Freeform II ??? you can unlock your mobile by unlock codes..the safe and best way of unlocking is by unlock codes and my personal request is that don't go for software unlocking because sometimes the software might get corrupted and may your data will be lost due to that,its my bad experience so I went for unlocking by codes from superunlockcodes and unlocked.you can too try but see to that whether your country and provider is listed..because for some service only codes are available..check with that and if your country's provider is listed then get codes and unlock your mobile..

samsung hue r500 and having problem when accidentally or curiously selected nam2.. after it powers off then on again by itself, it brings u to a little window (initial programming needed) and the enter code (password). as you will notice none of your 4 digit passwords will work, default wont work, u have to push the back or end call button to get away from the enter code window. enter ##626# and hit send button. it will bring u to option to select nam1 or nam2, select nam1.. go to next screen, enter in the sdc code which is 000000, (6 zeros), enter or next screen, make sure that mid is same as ur cell number, go to next screen, it will show ur number again, next screen, will be sid and nid numbers... they are what they should be, go next screen, then i think there is option to be done, view, edit choose done, next screen then it will program by itself. powering on then off, bringing u back to same screen with the same window of initial programming needed, just go to enter code, and enter the last 4 of your cell number, and it will let u through,.. just remember to go back in to your phone options menu and change the nam setting in there back to nam1 also. then it will power off and on again. program should be complete... you can always also dial *228 and option 2 to reprogram your phone again to make sure.
hahah

If you put your phone on nam2, like i did, you need to call samsung's hotline. customer service can provide you with the nam2 access code. Verizon would make you pay 59.99 to get a reflash to basically do the same thing. samsung's number is on the back of your phone

hi sir have you done restore factory settings firstThe Nokia 2160 series hand portable CMT uses an EEPROM NAM that can be programmed directly from the standard user keypad. In order to access the 
NAM, you must enter the special access code currently programmed into the 
phone. Once the programming mode is accessed, NAM parameters are loaded 
by entering them into the display and "storing" them to selected memory 
locations. Be sure to obtain all parameters before proceeding. 

EASY NAM PROGRAMMING 

1. Turn on phone. 

2. Enter the Easy NAM access code. Access code is: *#639# 

3. Verify the display now reads "Cellular Number" and enter the 10 digit 
MIN for the phone. 

4. Press the softkey under the word "OK" in the display. If less than 10 
digits are entered an error message will prompt you to reenter the 
number. 

5. Verify the display reads "Enter code" and enter the five digit SID 
followed by four zeros. (Example 001750000 is a SID of 175 followed 
by four zeros). An error message will display if an incorrect entry 
is made. Do not add more than four zeros to the code. 

Note: Change the Lock code by adding a pound sign and new lock code after 
the code. (Example: 001750000#7788. Lock code = 7788). 

Change the Language code by adding a pound sign (#) and new 
language code after the code. (Example: 001750000#2. Language = 2) 

Language Code: 0 (default) = English, 1 = French, 2 = Spanish, 
3 = Portuguese 

Change the Lock code and Language code by separating each set of 
numbers by a pound sign. (Example: 001750000#7788#2). The SID = 
00175, Lock code = 7788, Language = 2 (Spanish). 

6. Press the softkey under the word "OK" in the display. 

7. The display will tell you t

If you know your original lock code, take it in to your service provider, each code is diffrent and can only be programed manually, if you dont know your original lock code you will have to sacrific all info pics,mess,numbers, etc. by a reset... I can guide you through the steps to erase all if you lost your Unlock code, or switch back to nam1 if you know your lock code, ( when you switch back, if security is on automatic lock, password is required) intial programing code is not your Unlock code.
