Hi
So I had the GB AT&T rooted stock rom installed unlocked and using it with t-mobile in the UK.
I followed the instructions here on how to install CWM and asked it to do a backup.
http://forum.xda-developers.com/showthread.php?t=1766533
I then followed instructions here to install full lite rom
http://forum.xda-developers.com/showthread.php?t=1890125
Booted it up and then found the phone had become relocked to AT&T so booted back into CWM and restored my backup.
Now I'm back to normal but the phone is saying its still locked, whats gone wrong?
Thanks

Its a problem with this phone, try the thread to unlock, if not, you will need to use the unlock code. Dont know why the problem, but sometimes happens that
Installed it but it says EMEI is undefined. Help!
When I check t-mobiles site the IMEI number that's registered is alot different than what the phone reports when I do *#06#
I seem to be able to browse the internet but I have no SMS or telephone call capabilities.

What can I do it seems to have this gibberish number of 004999010640000/04

Hi Guys, I am having a weird problem that needs your help. I have been using my unlocked Nitro HD (P930) with the official stable CM9 rom. After hearing all the goods of miui, i gave it a try (with full wipe, data/factory reset, cache partition, and Dalvik Cache). After flashing it, the first thing that poped out said the network is locked and the page for sim unlock was shown. I thought the miui might re-lock my sim so I entered my unlock code. Then it said, "andorid.com has stopped". All i could do is to forget the unlock and went on to the miui home screen. After that my phone cannot pick up any signal at all. I used nano backup to restore my original CM9, everything seemed to work fine but it just couldn't pick up any signal. I went to mobile network settings to select the netwrok operators, it failed everytime. I tried entering 2945#*930# in dialer, it only said "Mobile network not available".
I tried to flash the same miui or my CM9 rom again, but my phone still couldn't pick up any signal.
Thanks if anyone can help.

Have you checked your APN settings?
you may need to reflash another baseband as CWM doesn't backup baseband so your phone failed even after restoring. I think you can find the cwm-flashable baseband on the forum.

I set and save the APN but the APNs page remains blank after I have entered things like PROXY, MCC, etc.

Thanks for the reply. I found Drumist's threat about those CWM flashable baseband. I tried the v10j and the v10f, but none of them work. Sorry for asking this dumb question but what should I do next?

Someone else commented before about their phone re-locking itself without explanation. The solution was just to unlock it again. I'm assuming you still have the unlock code?
The problem is that custom ROMs are incapable of unlocking the phone. You have to return to a stock ROM to perform the unlock, after which you can then return to a custom ROM. The stock ROM can be a CWM-flashable version for convenience.

1. 2945#30# is to bring up the sim lock page, where you can enter your unlock code. But it seems to me it doesn't work when your phone is already unlocked or you have a custom rom (just like what Drumist said)
2. I wiped it every time I flash a new rom just to make sure my phone is complete "clean", but I have no idea what it does :silly:

Seems you are having the same problem as I do. Simply flash back to stock rom and then enter the sim unlock code again, then your phone should be back to normal.
Like the title says, i'm having a hard time unlocking my S3 running Cyanogenmod and 4.4.4. Is it the fact that it's running Cyanogenmod and not a stock ROM that's the hold up? I bought an unlock code from 2 websites and they don't work.
I'm running: CyanogenMod 11-20140805-SNAPSHOT-M9-d2lte
Android version 4.4.
Baseband I747MVLUEMK5
You need to be as close to stock as possible to unlock via code.

err on the side of kindness
I am having the same problems... 4.4.4 and I forgot to unlock it first. I can't downgrade and I can't unlock via code.
Are you running a stock ROM?
Revert to Stock

I tried with my offial att unlock code 5 times (which I thought would permanantely lock my phone while using the Slim Rom (4.4.x) . I reverted back to stock and followed the procedue at an external website that I cannot link to because I haven't posted enough. Just search 'galaxy s3 unlock code doesn't work' in google and you will find pages that give you some ussd codes to get into the debug menu. I followed those directions and when I rebooted and entered the code it worked.

Need little help from you.
Do you rememeber which stock image you used? What was the baseband version?
Back to Stock from CM11 and SIM unlocked
I was able to ODIN to stock ROM and SIM unlock the phone.
Background: My ATT S3 i747 was running CM11 Android 4.4.4. Baseband and Bootloader was I747UCDMG2.
Steps:
1. Flashed rooted stock ROM (root66_ATT_I747UCDLK3.7z) using odin from http://forum.xda-developers.com/showthread.php?t=1739426
Followed the steps in OP.
After flash ODIN showed PASS and phone rebooted. It was stuck in Samsung logo. I booted into recovery. Performed a wipe cache and factory restore.
Phone rebooted successfully after that.
2. Inserted non-ATT SIM and it asked for the unlock code. I had obtained the code from ATT before. Used the code and phone was unlocked.
The same unlock code did not work while I was running CM11.
NOTE: When running stock ROM you can follow steps in below threads if direct unlock did not work for you.
1. http://forum.xda-developers.com/showpost.php?p=58671214&postcount=152
2. http://forum.xda-developers.com/showthread.php?p=38767845#post38767845 This works only with stock 4.1.1 image (LK3 modem).
See http://forum.xda-developers.com/showpost.php?p=59029460&postcount=323
NOTE: If you need TWRP recovery, see http://forum.xda-developers.com/showthread.php?t=1739426 and search for "Odin Flashable TWRP Recovery" in OP.
You can download ODIN flashable TWRP from there.
Model : SGH-I317M
Network Locked: Rogers
I was running the official Samsung ROM with CF auto root. I made an EFS backup (Using EFS backup Pro) soon after completing the root.
A few days later I tried to flash the modem on my phone to enable AWS bands. After the process my phone got stock on the logo screen.
Then I downloaded the stock ROM + modem from samsmobile and restored it using Odin. The phone boots fine but has a null IMEI and baseband version. I tried restoring EFS using EFS backup pro and the dd command but no luck.
Then I tried the DN3 rom. My phone works perfectly. It boots fine, the network works fine, IMEI is correct!
The problem now is that I cannot unlock my phone. I have tried ordering an unlock code from 2 different websites. Both of them gave the same code. When I insert a different SIM and enter the unlock code I get a message "network unlock unsuccessful". The support team for one of the unlock sites told me enter the code from the UTMS debug menu. The problem is that this menu is not accessible in the DN3 rom. The other company (Koodo) refused to unlock unless I was on the offical ROM.
I tried opening nv_data.bin stored in the EFS parition and it is all 1's. Hence, My suspicion is that DN3 reads the EFS data from a different partition than the offical ROM (dev/block/mmcblk0p3 .
You could help me in 2 ways : Show me how to unlock my phone in DN3 rom. Help me get the offical ROM from samsmobile working.
Thanks in advance to anyone who responds.

So this is a koodo phone, correct? And you had previously unlocked via the service menu?
No Its not a Koodo phone, it is a rogers phone. It has never been unlocked before. Koodo can unlock phones locked to other carriers as well. I took it to them because they were offering free unlock service for new customers. The agent at the kiosk could not find the UTMS menu so he said he could not proceed with the unlock.
I have also tried getting the unlock code by paying a website $20. I tried entering the code but the unlock was unsuccessful. Their support team said that they can only support people using stock ROM and refunded my money.
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!
Thanks for the help

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.
