Unlock Code From AT&T Not Working - What Can I Do? [HELP]

I was given the unlock code and it still says request to unlock network unsuccessful, it's eligible to be unlocked...
All help would be greatly appreciated.

Should I try flashing over back to this stock rom and then see: http://server10.stockroms.net/download/GalaxyNote2/SGH-I317/I317UCALJ2_I317ATTALJ2_ATT.zip
I hate being stuck in a rut like this, already had my account transfered to a T-Mobile microsim. This is driving me nuts...
The person I bought this phone from said they updated but then when I checked it was still at 4.1.2 and said something about update interrupted...

Or which of these should I use: http://www.scottsroms.com/downloads.php?do=cat&id=71

Flashing a Rom won't unlocknyour phone..... Also what do you mean your still on 4.1.2?? That is the latest Rom for the phone. ... Where are you obtaining your unlock code from? The only time att provides it themselves is over the phone. You sure your not getting the wrong code?

Yes I got the code from AT&T over the phone, called them twice and got the same code 1-800-331-0500 they gave me 41907314... According to this: http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ if ya take the newest update, ya can't sim unlock the phone cause it takes out the “NW Lock NV Data Initiallize” (Step #9) according to YouTube user comments...
THIS IS WHY I'm wondering what Stock firmware I need to downgrade back to in order to get that option again and be able to sim unlock my phone.
So I'm wondering if it's I317UCALJ2 or I317UCALK7 that re-enables that option for me. Right now I'm on I317UCAMA4...

Sorry bout the 2 posts, I thought it'd auto-append them to my main post...

Okay now I keep getting errors on installing about a signature and then two file locations sdCard0 and I think extsdCard...
How can I fix this do I copy the image to sdCard (InnerSD)? Or do I need CWM to install for Scott's Stock ROMs?

Yup that worked, I had to use Odin and this image http://server10.stockroms.net/download/GalaxyNote2/SGH-I317/I317UCALJ2_I317ATTALJ2_ATT.zip and followed these instructions on installing it: http://androidromupdate.com/2012/11...y-note-2-sgh-i317-original-factory-stock-rom/ then unlocked it with the directions galaxynote2root.com had listed...

Yea after all that it's safe to upgrade back to 4.1.2 or 4.2.2 or nearly any compatible rom you like.

No I mean while doing this process? Odin thing.. does it matter which SIM I have to keep in note

This http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ is the tute I believe, gotta remember it's been 2 months since I did this, so I'm not quite 100% certain. LoL
I'll be having to do it all over again too, by the end of this week possibly, since some jerk decided to steal my note 2 I had to go to ebay and win a new one.
I don't think it'd matter during the Odin flash with a AT&T sim card or T-Mobile one in it, I can't remember if I did it with or without a sim card, but to be on the safe side I'd do it without a T-Mobile sim card in it, just for that first successful boot... Then do the 4.1.1 unlock code method, take the back and battery off then pop in the T-Mobile sim card(Or whatever other non-AT&T carrier sim card) and see if it done it correctly...

I bought an AT&T live demo note 2 that was used in an AT&T store. I used this method from youtube, popped in my niece's T-Mobile microsd and dialed 611. T-Mobile's customer service rang and answered showing it worked. You need 4.1.1 to use this method though. I'm going get me a microsim today since my vibrant doesn't use the micro.

The above is not true - if your phone has upgraded firmware, you will NOT see the item "NW LOCK NV RAM...." in your "NETWORK LOCK" "PHONE CONTROL" menu.
So, the ONLY two solutions are:
1) keep bugging ATT to create a case for you and investigate
2) downgrade to 4.1.1 modem (NEED TO READ/UNDERSTAND HOW TO FLASH etc.)
then apply the Samsung service menu "fix" as shown in the above video...*
*Then, you could upgrade to newer ROM... if you wish....:cyclops:

[Q] ZVA to ZVC

Hi,
My sincere apologies if this has been asked before. I am on Deodexed ZVA with SIM Unlocked and using GSM service in India. I got a notification today saying update has been downloaded. Should I go ahead and install it? (Such a Noob ) Will I brick my G2 as I have TWRP and also if not and will the unlock be intact?
Regards.

[Q] Unlock Samsung S3 SGH-i747M (possible???)

Hello everybody
I have a Samsung S3 SGH-i747M (from Canada) with 4.4.2 and version I747MVLUFNE6 which is locked. It asks for "SIM network unlock PIN".
Is there any way (I don't care for the warranty) to make it work with an other SIM? I am currently in Switzerland.
Thank you very much in advance!

No you'll have to either call the original carrier of the phone and request the code or pay for the unlock code.

Do you know a reliable site where I can ask for the code?

There's lots of them out there. Pretty sure eBay has some and you can judge by their feedback and ratings...can't think of any specific ones right now though.

The problem is that I don't know at which carrier belonged the phone and one page that I found,that doesn't require the carrier and I think read that is reliable (swiftunlock.com), does not include the i747m in the list.
Any ideas or any other sites?

Any that offer it for the I747M should work. Don't take my word for it though. Ask the vendor first.
Sent from my SAMSUNG-SGH-T999 using Tapatalk

All the sites that i found ask for the carrier which I don't know or to have the phone rooted and have a version lower than 4.1.1 which I don't .
Is there any way to find out at which carrier it belonged?
Or any other reliable solution?
Please... :crying:

Go yo swappa.com and check the imei. I think it shows the original carrier when it does the check.

That maybe true.....but I do know it doesn't work with ICS or JB 4.1.2 because [4] NW Lock NV Data INITIALLIZ does not show in menu.

Once you are on the 4.3 ot 4.4.2 bootloader, you cannot downgrade the bootloader and the 4.1.1 modem will not work on the 4.3 or 4.4.2 bootloader.
You must be on at least the 4.1.1 dialler and modem.

damnit, just saw this. Is there any way to downgrade to unlock the SIM? What about if im on a different ROM?

There is no free way to sim unlock your phone once you have the 4.3 or 4.4.2 bootloader on your phone.

How to know on which bootloader ( bootloader 4.4.2 or 4.3) I am coz I was able to install a custom rom on my SGH-I747M The rom is dirty unicorn android 5.1.1 lolipop rom so Can I downgrade coz if I remember correctly I upgraded from stock 4.1.1 so can I downgrade to stock 4.1.1 by downloading and injecting it via odin is it possible or will it hard brick my phone and can you give me way to confirm what bootloader I have ???

Boot into download mode and look at the screen. If you see anything about knox, it likely the bootloader can't be downgraded to 4.1.1.

Can you guide me that how to know which bootloader do you have i.e. do I have a 4.3 or 4.4.2 bootloader how would I know that? and also I do have a custom dirtyunicorn rom with 5.1.1 so is it possible for me to flash the 4.1.1 stock SGH-I747M rom to it and then unlock it and then again add my current rom and use it???

Download and install the Samsung phone info app from the play store, run it, and look at the last three characters of the bootloader. If it is mk3 or higher, the bootloader can't be downgraded.

Not quite sure where to put this but I have just successfully sim unlocked a samsung galaxy s3 sgh-i747m on 4.4.2 .This is only prelimary but upon unlocking and inserting a Public Mobile sim I was able to text on a Canadian Rogers S3. No further testing has been done. I first rooted the phone using Kingoroot and then downloaded the phoneinfo app from play store. I then used the app to get to service menu.At first service menu is blank but I used menu ,then key input Q, then back, then key input 0000,then back and then service menu appears. Now I am doing this from memory and no longer have the phone or another one at the moment to confirm this and will update this as soon as I can. But to the best of my knowledge I first went to UMTS(1) ,thenDEBUG(1), then Phone Control(?), then Network Lock.. Perso-SHA256 was on(1) I set it to off (0). I then backed out of the menu and shut down phone.I inserted PM SIM in phone and booted up .Phone didnt ask for unlock code and shortly I had texting service with Public Mobile. I dont have voice or data to check those but cant seewhy they wouldnt work. Anyway can someone confirm this working.My steps may not be exact but if it worked for me it should work for others.

Your rom is not official. As you can see in build number shows. Some weird company name not the samsung build number like "N910PUV2DPK4" etc it should show ike this so it means it was rooted before to make some modifications such as sim unlocking.
If you still want to make sure that your rom is official or custom just go to odin download mode and check binary status and system status if it shows custom then its modified.
Until your rom system is modified you can never apply official ota updates from samsung.
Best way to make your phone fully official is just flash stock rom via odin but your phone may end up sim locked if you are not using sprint sim card and you must activate it via sprint network to unlock it.
so my best suggestions will be just postpone updates and use as the way it is if you are not on sprint network.

Thank you very much for replying.
So if I flash stock rom and I get sim locked, so there is no way to unlock it to work with other sim outside USA?
Second question can I root my phone. Because using root checker it says "sorry root access is not properly installed on this device ". Means my phone is not rooted.
I will appreciate all help. Thank you all in advance

Hi
I made a stupid mistake with my G988B, its were not working well, so I decided install a stock rom, but downloaded and installed o last version of software from another country (G988BXXS2ATD5, XEF ) whit Security Level Patch of may 1, 20.
After installed new stock rom, my phone ask for Network Unlock Code.
When realized of my mistake, tried reinstall orignal version of firmware (G988BXXU1ATCT, PGU) but nothing work for me. I have tried to flash with Odin, but always, process stop in "flashing vbmeta.img."
I have read a lot tread trying figure out my problem like: https://forum.xda-developers.com/galaxy-s20/how-to/howto-root-s20-series-upgrade-firmware-t4079353/post82220417#post82220417
There is a way to come back original stock rom and then trying unlock network?
Could this process work in my case without damaging my phone?
Thanks.

Thanks por your answer, but I did it.
It doesnt work.

Samkey is the only way to unlock a Samsung phone other than getting the network unlock code from the network or third party. You must know what you are doing. Google the process. If that doesn't work then there is an issue here that needs further investigation. Also ensure your active csc code is the one that was originally on the phone as well as stock rom. Sam key can be used to change csc as well.
Good luck

Thanks mikey_sk,
My problem is that both the csc code and the stock rom are not the original ones. Therefore I am looking for a guide to help me how to get back to the stock rom.
I have read that the problem is, the security patch that I installed as it is newer than the one I am trying to reinstall. I will keep trying.
I understand that so far there is no way to go back from binary 2 to binary 1.
Any help is appreciated.

Ok,

No more questions.

You can always use the sim slot 2, it is usually not locked.

I suggest you change the csc to a stock one using Sam key. Make sure you enable USB debugging in developer settings otherwise Sam key won't work. After that dowload the most recent stock rom for that device from sammobile and flash in ODIN but DO NOT use HOME_CSC so it can do a full wipe and rebuild the firmware. As an added measure as soon as installed go into recovery and do a full wipe. If network is still locked try unlocking it with samkey

Unfortunately for it, you mentioned only sim1 is blocked and you still can use sim2.
This is not network lock but rather imei blacklist.
The only way to fix this is to pay your telco bills from where you purchased the phone. If it's a used phone, I would get a refund. There is no roms you can use that can fix it as it's blacklisted from the telcos.
There is only 2 reasons it is locked.
1. You didn't pay your installment bills.
2. The phone is reported as stolen.
If you purchased a used phone, get a refund.
