This method has been sent to me by android235, I can not personally attest that it is working so please if you do that, make sure you have a backup or odin to reinstall your phone
After root, use a file explorer.
I use the ES File Explorer downloaded from the market:
- Launch it
- Goto "Settings> File Settings". Be sure that Show hidden files is checked
- Also be sure is checked "Settings > Root Explorer"
- In "Settings > Home directory" write "/" (without the quotes)
explore the "efs" folder in the root
- move the following files in a backup folder somewhere to your internal SD card (you will need them if you want to restore later to original phone setup) : .nv_core.bak, .nv_core.bak.md5, .nv_data.bak, .nv_data.bak.md5, nv_data.bin, nv_data.bin.md5. Moving them they will be deleted from the efs folder (that's ok).
Reboot.
Now you will have it unlocked but with the generic IMEI.
Peace out.

Any way to restore the IMEI afterwards? Or is the simlock check based on the IMEI?

I suppose the files you saved are to restore if needed, for the rest I don't know as like I said did NOT try myself
Nah. I meant whether it is possible to restore IMEI while still having unlock. If I restore the files, the lock should be back. (My glide is unlocked, but thats not the point)

I'd rather spend 25$ for an unlock key on Americanunlocker.com
(worked great for me)
In fact, I have tried to hack the nv_data.bin but seems that it is not the same as galaxy SII and galaxy S.
Although you will get unlocked (generic IMEI) when removed those files,
I highly recommand that you have to backup them in a very safe place. Otherwise if you encounter any problems, you have to sent back to AT&T / Rogers.

The method will work.. i had tested it earlier.. a generic imei will be assigned..
however some operators do not accept generic IMEI..

This method is perfect ! My phone accept the Free Mobile's SIM card and is recognized by Orange and Free Mobile's networks.
(It connects too on the two another french carriers when theses networks are too low, I don't know why and if the reason is the AT&T ROM or the unlock method. By the way, although I am connected I can't do anything.)
i don't like having a genric IMEI. will wait for anther method or just pay for an unlock key (when i get my device ofcurse )
What do you mean by generic IMEI? Is it all 0s? Does this mean that it will no longer be detected as a smartphone?
I just tried this method and it did work for me thank u
one Q is there any way to fix genric IMEI and keep unlock .
Edit: I restore my files from a back up and relock the phone ..went to ebay bought unlock code for about 8 dollars ..Done

I've done the same thing with another website -more expensive x-( (Fastgsm.com), although it worked.
The only problem though is that every now and then the phone asks me again for the network unlock code. This has forced me to carry a text message with the info on the phone. So far it has asked me 3 times the unlock code. Every time I input the same code received, every time it accepts it and gets unlocked. But I think this is strange, this is the first phone I had that this happens.

Captivate Glide (Rogers version I927R).
I'm very interested in this thread since i'm french, and about to buy a phone in the US to use it here, in France.
If i understand well, the trick for unlocking it by file deletion is a bad idea since generic IMEI are not too well accepted on french networks, and when you buy an unlock code, it keeps prompting you sometimes.
My other option is the myTouch 4G Slide, so i'd probably better go for it

Unlock phone, sim, root, odin, flash cwm, flash twrp, use your "unique key", wtf?
Excuse me. I do this a couple times every year or so and I'm still confused as to what's going on? And why do I have to keep doing it? I just got a new AIO sim card and it requires some code to unlock. Does that mean my phone unrooted itself when I flashed the latest stock rom in here, which btw finally a fully functional ROM, go figure... And what's the difference between using odin and this code sequence from the dialer method I found somewhere where you punch in a long *#blablabla# code which puts you in the matrix where you do a little dance here and there then viola your sim is unlocked? Anyway, if these are all unrelated, what is this unlocking my sim business and when the heck does rooting actually occur within the maze of steps Odin takes you. And why all this after I flashed the stock rom? It's supposed to retain your rooted state still no?

So let me see if I understand your statement. You flashed another ROM... and then got a new SIM for your phone, but when you turned it on it will ask you for an unlock code? Rooting and unlocking are two different things, you can be rooted and not unlocked... so what you need to do is follow the unlocking method. Or... I don't seem to understand what you mean, can you be a little more specific?
Sorry. It's confusing. I'm stuck at the sim unlocking part, where you can put in a code from the dialer as shown here: forum.xda-developers.com/showthread.php?t=2024514
Unless you know your unique code to unlock your sim whatever that means. So I should still be rooted but now somehow still locked or something? Or is it just the sim that is locked? I'm fine with my old tmobile sim/account in place as in as I'm writing this, but as soon as I pop in my aio sim, back to that thread but id need to install uvle1 but b4 I do all that I just want to know what and why I am doing. Should I continue? What exactly will I be doing? Thanks
Sent from my SGH-T989 using Tapatalk
Sounds like right now your phone is carrier-locked; i.e. your phone will not work with a sim card for a network other than T-mobile's. Rooting will not unlock your phone for use with another carrier's sim card, however, the instructions in the thread you linked in your post will. If you really want to use that AIO sim card without paying for an unlock code from T-mobile or some other source, then the instructions in that thread are probably the best way to make it work. UVLE1 identifies particular modem/radio firmware and stock ROM that needs to be installed on the T989 in order to have access to the menu items required for the unlocking process. You can switch to the most recent radio or any ROM of your choice afterward without losing the ability of an unlocked phone.
My friend, you have a lot of studying to do....I'm sorry, but you seem awfully confused. No insults intended.
Please read all the stickies and then some.... before you attempt anything on your device. Very bad things can happen if you don't understand what you are doing and exactly how to do it.
Good luck!

Okay in up to speed now on all this. I've known this stuff at different points in my PDA phone assisted life but due to my own RAM deficiency i easily forget this stuff. Especially since I only learn it over a few days of the year.
Anyway, I forgot I never unlocked my phone because I never even needed to till now. My phone had always been rooted as I've been swapping ROMs for a while now. Well I'll go work on that solution now. Thanks for the replies

Good day my phone is not connecting to any network. When I insert my sim card it just writes emergency calls only... it doesn't even prompt me for the sim unlock code....plz help
So, I have contacted AT&T about my move to T-Mobile and that I needed my phone unlocked. They told me how to do it and once I received the code, I tried it with my cousins sim card (T-Mobile) and tried it twice, but it failed. The email in which I received the code stated that I only have 5 tries before it permanent locks to AT&T, so I stopped trying. I went to the T-Mobile store and tried with a sim card there, and it failed again. I now only have 1 last try, so I want to know if there is a way to unlock my phone after it has been rooted. I suspect the reason my unlock code is not working is because of my phone is rooted, and running the slimkat image.
Does anyone know what is the best way to proceed from here? I don't have the original image from my phone anymore, but I have my sister's phone and if making an image of her phone would work to restore my phone to AT&T, then I can do it. But if there is another way of doing this, please let me know. I even tried using some unlock tool app, but it failed. It actually doesn't do anything. I tried SGS Unlock Tool and CSC Select.

I don't believe it failed do to being rooted so much as being on a custom ROM and not having the stock dialer. You will probably be best served by reverting to a Stock ROM before using your last try. BE CERTAIN you flash the ROM appropriate for your current bootloader and modem. If you fail with your last try your only recourse will be to purchase an unlock code from a third party, or so I have read (unless you are still on the 4.1.1 bootloader and modem).
The best bet is to revert to stock unrooted if possible. What is your current boot loader? This is extremely important as this will determine your options, if any, of returning to stock and methods of unlocking.
Well, I rooted my phone back when I first got it (2 years ago), so I am not sure what boot loader I have (I think I was running Jelly Bean 4.1). I know that I never updated to anything afterwards. It was not until recently that I updated to the SlimKat, rather than trying to update to an AT&T image. If I was to install one of the stock ROMs, do I need to use my computer, or can I use TWRP? Or do I need everything to be stock?
Before flashing anything, download the Samsung Phone Info app from the play store and confirm the bootloader and modem currently on your phone. Post the version here and we'll try to help you get your phone unlocked.
Root gives you access to system files and does not have an effect on entering an unlock code into a stock ROM.
I just download an app called "Phone INFO Samsung" but I don't see anything under "Firemware's CSC Code" -- totally blank. When I choose to browse firmware, it only shows me the year 1970-01-01, and CSC: ATT. The Mnufacture date: 2013-01-19
You need to look for the bootloader, not firmware.
If you have a terminal app on your phone, open the app, type su and press enter. Type getprop ro.bootloader and press enter.
okay, this is what I got:
I747UCDLK3
Thanks for helping out with this.
So, since my attempts of unlocking have been on the non-Stock ROM, does it still count towards my 5 failed attempts? Or is the phone able to keep count of the attempts, regardless of ROM? I would assume that since the correct ROM has to be installed for the unlock code to work, then shouldn't the ROM be the one keeping count of the failed attempts, too? Just wondering...
Since you are on LK3 bootloader, that means you can use the free method to unlock your phone.
You can use Odin to flash the stock ATT 4.1.1 ROM from sammobile.com: http://www.sammobile.com/firmwares/database/SGH-I747/.

Sorry to be such noob at this, but do I need to use (Odin via) my computer, rather than using the TWRP recovery tool already on my phone? I know I have not gone through all the research material, I just did this once and never looked back, I am still in the noob stage.
Yes, you must use desktop Odin (I recommend Odin 3.07) to flash stock 4.1.1.
If you decide to flash using Odin, uncheck everything except f.reset time before flashing. After flashing and you see the word "reset" in the status window, remove USB cable, remove battery, replace battery, boot into recovery, do a full factory reset/wipe, boot the phone, use the free method to unlock the phone, restart, and you should be permanently sim unlocked.
Okay, got it! Thanks for the responses, and I appreciate the fact that you guys did not just send me searching through the tons of threads you have compiled in the forums. I was sort of expecting to be chastised for not doing extensive research before posting. You guys have been great!
Hey there,
I am having some issues with unlocking my D852. The phone is locked to Rogers, and I'm trying to get it over to Telus. I'm in the stock ROM, with the Telus Sim card in it, everything appears to go smoothly after I enter the unlock code. To verify I go into 2945#*852# and check all the menus, the phone is not personalized, and I'm successfully connected to the Telus network. Afterwards I try to restore from a backup, CloudySix, the phone boots. In the status bar its saying that my SIM Card is Perso Locked, and is prompting me for a SIM Network Unlock PIN. I tried entering a few codes, NCK and SIMCK without any luck. I dont want to enter any more codes in case I lock myself out completely.
I have unlocked before, its been a few years, but I have never run into this. Shouldn't the phone be unlocked permanently, no matter what ROM you flash. Maybe I have to flash a new ROM from scratch? I tried restoring CandySIX CM13 edition and the new AOSP based so far.
***EDIT: I forgot to mention, I reverted back to stock, and I get a prompt for the unlock code again.
I just got a Galaxy S6 from Telus and I'm really not happy with it, it feels like a downgrade to me. Hoping you guys can help me out
When you restore your backup are you restoring the EFS partition as well? I think that is where the unlock is stored (at least that's how it is on some phones).

Yeah, I was doing a full restore, EFS and Modem. I tried flashing a ROM from scratch just now and that worked for me. The only problem after that was that my WIFI wasn't working afterwards. I might have to continue messing around with it, making progress though!

Got it all up and running, after an hour of troubleshooting I discovered that the WIFI wasn't working because the AP needed a reboot lol. Through all this though, I discovered the importance of the EFS partition, it stores alot more than your unlock data, its best not to touch it
How were you able to unlock the network sim.
First I want to say thanks in advance to anyone reading this as I have been a long time visitor and this site has helped me unlock & root quite a few devices over the years.
Anyway my daughter was messing around with my wifes phone and somehow got all the way into the factory reset option and did it. Dont ask me how as im still wrapping my head around that one. Weird part is the phone wasnt rooted after (I thought it stayed rooted regardless but I guess not). I have since gotten it rooted but I am unable to find out how to unlock it and neither of our sim cards seem to work on it now. I typed *#197328640# into the keypad and went through the menus to do a phone unlock but as it is on 4.4.2 I was unsuccessful. Any help would be greatly appreciated. If needed it is a Samsung galaxy S3 SGH-1747.
Once again thank you so much for any help.
This is strange that the phone would become sim locked after a factory reset.
Was the phone sim unlocked using a sim unlock code or the free sim unlock method?
If your daughter got that far, is it possible she also somehow messed up the modem firmware or whatevs? Maybe try flashing a new modem?
(Careful, I've never done this and you could probably brick the phone if you flash the wrong one)

Definitely read through it though and make sure you have the right model, version, etc.
Is it possible to find (e.g. borrow from a friend) a sim card from the phone's original carrier to see if that works?
