UNLOCK Sch-U740 nam2 Guide!!!!
I switched my nam setting and realized i was screwed when it rebooted back up so i googled it and found this page it was a little hard to get so here is the step by step walkthrew for the u740 and i dont think its much different on other samsung phones. ps first post give me a break.. :)
If Bitpim not set up-Need cable and bitpim..bitpim dosent support u740 so use a950 phone type. search google for more info.
Go to view-file system make sure its has a check mark by it- in bitpim. the file system will appear on left side. click it, it will then show a folder with a slash(/) maxamize that (might take a while to load) that shows a bunch of flies and in thoes is one called current_prefs.db right click it, save.., save it to your desktop, minamize bitpim, down load sqlite broser Here like cody666 mentioned above. un extract it open sqlitebrowser and open the file you saved (current_prefs.db) once that opens go to the brose data tab. select the table "common" and for me it was line 74 that gave me my nam2 unlock code. If not look for "pref_device_lockcode_nam" and under the value colum is code.
If this works for you or you have any questions please email me letting me kno it did. Id like to kno i helped someone today.
I just wanted to let you know that you helped someone out and your directions were perfect...... You saved me having to get my daughter a new phone. The verizon tech support are absolutely useless they told me that the phone was not good anymore and that there was no way to unlock it. My choices were to pay 50 dollars because the phone was out of warranty or to get a new phone at the retail price because the 2yr pricing was not available for her phone yet. I am just glad that I checked online and found this post before I spent the money and fell into the Verizon Trap!!! Thanks again....

I contacted samsung via their online email support thing; I told them that I switched to NAM2, and gave them my serial number. 10 minutes later they emailed back with the correct unlock code. This was after 8 hours of messing around with bitpim.
wow....I am really surprised...
im not going to touch on tech experences that other people have with verizon but reading a lock code from a samsung shouldnt be a huge deal (cept for the juke since its defaulted to mpt device) the very first page on the samsung pst software gives the user the option to read the lock codes from both nams. all that is required is to hook up the phone, run samsung pst, read the phone using verizons default 000000, and the screen will populate. lg's software is simpler with a nice big "lock code" button. motorolas take some doing with the RSD tools that they are currently using.
again im just surpised no one even mentioned using the samsung pst utility.
ok, so i had my samsung glyde phone in my pocket all day, and when i got home, i took it out, grabbing the screen. first mastake i made. the phone had been unlocked in my pocket all day, so it was hitting keys as i moved around. i took it out, and just happend to put my finger im guessing on the NAM2 selection.phone then says- changing settings to NAM2 must restart phone. so here i am thinking, " oh its no big deal, ill just change it back". well, it turned out to be quite the big deal, because i couldnt type any code that i was told/thought it would be. so i did what any one would, i called verizons tech support line. they said, theres no saving it, you have to wipe the phone. so i went to samsung.com, and got the support line for them. and went through the promptings, and got to a tech, who to my luck, got my phone unlocked. you need to call from a house phone, have your samsung glyde- thus the only phone i know that this works on~ and go through the phone prompt, get the tech to get your info, tell the your phone got set to NAM2, and is now locked. they hopefully will do like they did to me, and tell you a code. the code they gave me, which i imagine wont be the same for all was 2375 or something like that. and there you go, the phones unlocked, you set it back to nam 1 and youve got your wonderful piece of machinery again. hope ive helped all of you.
the way i previously stated, is proven to be the easiest, least harmful way to do this.
Verizon is completely unwilling to help.
Samsung will help. You can call their tech support, but I found it much easier to e-mail them. Tell them you switched to NAM2, and include any serial numbers on your phone. By giving them the serial number, they can give you the default unlock code for NAM2.
if you have locked yourself out of your samsung cell phone due to switching to nam2 with the lock on powerup option on, here is your solution. open the back of your cell phone. there should be a hexidecimal number printed on there(behind the battery) it will be a bunch of letters and numbers. its the last number printed. meaning it's on the bottom. open up your windows calculator. you know the one you would use to help you with math. go to settings or view and switch to scientific. after that make sure you check the little circle that says "hex" after you have imput the number switch the calculator to "dec" for the decimal conversion of the number you have just put in. the last four of this number will be your password for your phone. i swear this works on any samsung phone. i locked myself out of my 740. it works trust me if you don't believe me here is the website i got the info it's the samsung tech support page

Wow nice catch. I did some research on what masterscott87 talked about and thats the simplest, fastest way to switch out of nam2. The question is what other phones does it work on??
Just call samsung and they will give you the code in about 4 min. I tried BitPim and QPST for like an hour or two.
Thanks MasterScott. I stressed when I locked myself out, today. But your directions were perfect!!!
By the way, it worked with my SCH a930. Oldie, but still like it!
I'm not sure if this is really necessary for anything other than Samsung phones, but I've only ever seen this issue come up when dealing with Samsung phones. Here's a scenario: You're messing around with the various settings in your phone's menu, and you switch your phone to NAM2 in the process. Your phone resets, and you find that your phone is now locked. Unfortunately, your normal lock code doesn't work. What do you do?
First off, you should probably understand what NAM1 and NAM2 are. Basically, think of them as containers. Each of these "containers" holds a phone number. Yes, you can have two phone numbers on a single cell phone. I generally don't recommend it, though, as you can only have one of the two numbers active on the phone at any given time, meaning that you'll miss all of your calls on the number whose NAM you're not on at the moment. Also, NAM2 generally can't accept over-the-air programming, so you'll need to manually program your account information into it, and you'll need to have updated roaming information loaded into your phone in one of your carrier's retail stores (assuming that they even support NAM2).
So, why am I telling you about NAM1 and NAM2? Well, your default lock code (assuming that you never specified your own) is generally going to be the last four digits of your phone number. Problem is, NAM2 doesn't have a phone number in it by default, so you'll need to somehow figure out what the default lock code is set to on NAM2.
Secondly, you'll need to locate a hexadecimal code, usually found inside of your phone's battery compartment. There are two different types of hexadecimal codes that you'll need to be on the lookout for: ESN and MEID. Now, Samsung phones generally don't have these numbers labeled, but it's easy enough to find them. An ESN in HEX format will be eight characters long, whereas an MEID in HEX format will be fourteen characters long. MEID's tend to begin with the letter A from my experience.
Now, depending on which type of hexadecimal code you found in the previous step, you'll need to take one of two different paths in determining your unlock code...
Let's start with the easier path, the ESN...
Thankfully, all you need for this one is a scientific calculator. If you're using Windows, then simply launch Calculator. Once you've launched Calculator, you'll want to choose View > Scientific from the menu bar.
Once you're in scientific mode, click on the Hex radio button, then enter the eight-character ESN.
Now, click on the Dec radio button to convert your ESN into DEC format. Now, do bear in mind that this won't be the same as the ESN number in DEC format on your phone's battery compartment label. That's why only the ESN in HEX format is important. Anyway, the last four digits of the resulting number are what you'll want to enter in order to unlock your phone.
Now, let's move on to the slightly more involved path, the MEID...
Really, the only reason that I consider this to be harder than the previous path is because it requires a tool that isn't available on most computers by default. Basically, you'll need to find a hash calculator, specifically one that's capable of working with the SHA-1 algorithm. You don't really need to understand what the SHA-1 algorithm is in order to unlock your phone, but - in case you wanted to know, anyway - I suppose that it'd best be described as a method of making pieces of code more secure. SHA-1 and other similar algorithms simply make changes to code in order to make said code more secure.
Anyway, I'd recommend HashCalc, as it's free and easy-to-use. Once you've downloaded and installed HashCalc, launch it. Change the Data Format option to Hex String, then enter your fourteen-character MEID. Be sure to check the SHA1 checkbox, then click on Calculate. See that long code that appeared to the right of the SHA1 checkbox? Write down the last six characters of it, as they'll be vital in determining your lock code.
Now, this next part will look more than a little familiar. Basically, you'll want to have a scientific calculator for this, just as we did for the first path. Again, in Windows, you can simply launch Calculator and choose View > Scientific from the menu bar.
Once you're in scientific mode, click on the Hex radio button. There's a problem, though: We don't have an eight-character code to put in as we did before, and we need an eight-character code in order to figure out our lock code. Well, thankfully, the first two characters in the eight-character code are always going to be 80. As such, your eight-character code will be the number 80, followed by the six characters that you wrote down after using HashCalc. Now that you have an eight-character code, input that code into your calculator.
Now, click on the Dec radio button. As before, the last four digits of the resulting number is your lock code.
I hope that this has been helpful. Please, no more messing around with those NAM settings.
