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...

hi
I am having the same issue, I got unlock code from ATT but it says network unlock request unsuccessful.
so if I follow above instruction to go back to 4.1.1 I will be able to use the unlock code right?
can you please give me few steps which you used for unlocking... then unlocked it with the directions galaxynote2root.com had listed.<--I dont find it.
I will try to flash it.
and after unlock can we do factory update 4.1.2?

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:

How to sim unlock the trac phone sgh-s970g galaxy s4...and possibly others

Ok so this is still a work in progress but it works, and lte works on my att and tmobile sims. Ill post as many screen shots and be detailed as I possibly can so bear with me.....
So i have a samsung galaxy s4 the sgh-s970g, and a customer needed it unlocked so I thought I would give it a try. Its been a fun phone to mess with. So I am on 4.2.2 and this is the only version I have tested on. I havent tested on 4.3 so let me know if it works for you.
So my baseband is MH3. I used saferoot to root the phone and then I used the twrp for the m919 version to get a custom recovery. after this i went into recovery and made a nandroid. I would advice you do the same if your going to try this, because I am in no way responsible for anything that happens to your phone it will trip your knox counter and your warranty is now void.
ok so I have a tmobile sim in the phone the whole time because it gives you a invalid sim message and when you get rid of that the phone is unlocked. Now I flashed the wicked v-8 4.2.2 custom m919 rom onto the phone. And after that i booted it up like normal and had no problems booting it. So when it finally boots up this is what I see....
know with the tmobile rom it is asking for a sim unlock code. This is where it gets a little tricky.. Youll need to download region lock.apk
you can get it from the play store or from the developer on xda, (great app by the way). So now is when i procedded to use spt box to unlock part of this but i believe you can do it without the spt. so just set your phone up and when your done your settings should look like this... youll still have straight talk radio but everything else including kernel is the tmobile m919.
Ok so now go ahead and open up the region unlock apk and instead of pressing unlock your going to lock it. when its done go ahead and reboot it and then its going to ask your for a password again but this time you know it.. Its going to be 00000000, or atleast it was for me but like I said i dont believe spt is needed to reset the efs i believe the region lock apk will do this and it shoould say unlock succesful like this...
the only kicker is anytime you reboot your phone your going to have to run region lock and lock your modem and then reboot and type in the 8 zeros to unlock if someone figures out a better way that would be awesome.. I also believe this method could be used to help unlock the s4 l720t and sm-n900p without the assisstance of sprint. Any feedback and help would be greatly appreciated and enjoy your unlocked phone....

Region away app works only up to 4.3, so I guess you need to downgrade the baseband to L720T's MK3 modem.
No harm in trying.

the l720t was actually shipped with a 4.2.2 rom and if you could find that modem for the 4.2.2 it was originally shipped with you can unlock it

I can only find a 4.3 ROM for L720T not any version before it.

So, just to clarify, do we have to use the ROM or can we do this on stock? I have two of these LTE-T marked phones from Straight Talk that I'd like to use AT&T Straight Talk SIMs with.

tried this on a stock tmobile mdl firmware with the mh3 baseband with no go.. What am i doing wrong?

Has anyone been able to unlock these tracfone devices officially through a tracfone provided unlock code???

Click to expand...

Yes i have, Tracfone will have to provide an update to fix the issue. Reason is that everytime you enter the code its accepted. But as soon as you reboot the phone it asks for the code again. So not sure how tracfone will handle this.

Well I returned my $250 Black Friday special as I just have no faith in getting an unlock code for these Galaxy S4s as I wanted to use it on AT&T and I had picked up the Tmobile version. I'll have to settled for a used item instead.

So will this phone work with a straight talk att Sim and a tmo Sim as long as its through ST?

After fallowing all the steps I get to the 8 0's hit enter and it just sits at the screen, and says unsuccessful. Sgh-s970g bb:mh3 av:4.2.2

Anyone know of a pay site to unlock this device. The one legit one was for over seas and I'm in US. I tried offering straight talk money and they said this phone needs to be active for 5 more months before they'll provide me the unlock code. I guess you need 12 months of active service to be eligible for the unlock program. The only thing is, is it will only work on a straight talk T-Mobile Sim until then. Tia.

It DOES work. I installed the wikid v8 rom on a SHG-S970G this morning, opened region lock, unlocked modem, relocked modem rebooted, and entered my unlock code and BAM, Successful unlock. Thanks a grand! By the way i bought the unlock code on a 3rd party site. Im now running ATT on the phone.

Straighttalk will only unlock phones purchased on or after Dec 2013, currently active on ST Service & have been active for 12 consecutive months, if you call the unlock department you will be transferred to their automated information center if your phone is not eligible for unlocking, this is just to inform you of the requirements to unlock your device.

ST unlock
I've had mine 6 months... Called them 5 times and they told me everytime they couldn't unlock my phone (sgh s970g). So.. I used CHIMURA to root for free. Installed the m919 twrp for recovery. Installed wikid v8 using twrp installed regionlockaway locked the modem rebooted, entered my unlock code and it gave me a successful unlock. As stated I'm running a Straighttalk AT&T sim on mine.

Extrapolate to S5?

Do you think a similar technique can be applied to a Galaxy S5 from Net10/TracFone? I tried to use a S902L with my (Canadian ) Rogers SIM card and unsurprisingly, it didn't accept it

By Sim unlock, do you mean you want to use an AT&T phone on another carrier? If that's what you are looking for, give me a few minutes to test something.

Yes, of course.
But I am fairly new to the note 2 so I don't have much stored up information. I now see a post that indicates that flashing a certain 4.1.1 modem, MJ2 I think, gives the user a service menu where you can change the unlock setting. So now the OP's question makes sense. Only he should have been able to find the same post I did.
In a minute, as soon as my wife lets me borrow her phone, I'm going to test an unlock tool I know about to see if it works on 4.4.2 stock.

The dialer codes that worked on 4.1.1 to unlock the phone via the hidden menu. Does not work on 4.4.2 anymore. And being you took the ota update, there's no way of downgrading you firmware...
Sorry to tell you..
Another way is to contact AT&T by email, about unlocking the phone. Can't remember what the exact name is, but goggle search it. They'll send you the SIM code, if the phone is out of contact!!! Takes about 2-3 days when I did my skyrocket to run on TMO.

Sent from my T889 N2/N3/S5..

At one time, there was a free app on XDA called GalaxSim Unlock. For some reason, the developer pulled the free app download, and the only version then available was the paid version on Play. I have a copy of the free one from before it was pulled, and it works on the Captivate and the Galaxy S II, and some other galaxy phones, not sure which ones. So I tried it tonight on my wife's Note 2 which is running Stock NE5 with TWRP recovery and has the MC3 boot loader. However, the unlock failed, saying unable to read nvdata. So it's apparently a no go on this phone.

That only works if the contract the phone was in was not defaulted, and or you are the original owner of the phone.

re: sim unlock
I recently bought a soft bricked SGH-I317 (stuck on "firmware upgrade encountered and issue"). I tried flashing LJ2 firmware and got it to change to being hung on the "Samsung Note II" logo. I think this is when it changed as I was trying all sorts of flashing trying to get off the "firmware upgrade encountered an issue" screen (also Kies would not recognize that the phone was connected). Tried different recoveries and firmware without making any progress until I flashed the 4.4.2 (I317UCUCNE5) bootloader. The phone booted into Philz recovery after that. I then flashed the stock LJ2 firmware w/ LJ2 modem, sim unlocked the phone and then flashed Skynote Air 4.3 along with the 4.4.2 (NE5) modem. This is the setup that I am using on T-Mobile now with no problems except that the Knox counter is tripped. Hope this helps shed some light on the problem.
I discovered a problem with Skynote 4.3 with the 4.4.2 bootloader. If I try to charge it with the phone turned off, the phone will freeze at the empty battery symbol and requires a battery pull to get the phone to turn on. Everything else seems to work okay.

My sister sell her note 2 to me because she's gonna upgrade to samsung galaxy S5. It was an att and I'm using T-mobile.
I did check the baseband ver and It was i317UCUCNE5 (4.4.2 OTA). the question is it is safe to flash base band ver i317UCALJ2 using ODIN?
Can you do the step by step process and also links of the files and software did you use please? thanks

It's a network unlock, so you are free to use any GSM carrier. You can lock your sim card -- then a pin is required for your phone to connect to your carrier. It's the old skool method to stop unauthorized use, from the days before a lock screen pin.

I bought a SGH-I317M today off someone. It was locked to Bell Canada. I did the dumb thing by letting Kies update the firmware. And as i've read I'm pretty screwed for downgrading it. I tried unlocking it but the hidden menu didn't give me the 4th option in the network lock path. So i tried bunch of things which at one point required me installing Kies for drivers and thats when I i let it slip and update. So now I'm still searching for a method to unlock my phone. I've gotten philstouch recovery on and Skynote working. I just tried flashing the rogers_j2 modem.. hoping this will work.. you think I should just pay one of those sites or a retailer for the sim unlock ccode?

So i tried bunch of things which at one point required me installing Kies for drivers and thats when I i let it slip and update. So now I'm still searching for a method to unlock my phone. I've gotten philstouch recovery on and Skynote working. I just tried flashing the rogers_j2 modem.. hoping this will work.. you think I should just pay one of those sites or a retailer for the sim unlock ccode?

Please let me know if it works. mine is galaxy note 2 4.4.2 NE5 baseband and I've done some research and they said that if you upload your firmware thru OTA there is a possibility that it will soft brick you phone due to unknown security reason.
I'm just waiting for conformation from some one that it's safe to flash J2 modem on a NE5 OTA

in the US, if your phone is more than 6 months old and your contract is in good standing you can ask for the unlock code. I don't know if Canada is similar.

I was going to post the same question about unlocking I317 4.4.2, and found this post which is similar to what I'm looking for so just want to add to pump the question.
It's been a while but I have done unlocking for other At&t models (S3, S4) and learned that later versions don't with the option in hidden menu to unlock, and the work around is to downgrade. However with devices that have OTA updates, it's not possible to downgrade the bootloader.
Is this the same for Note 2 I317? If so, any other method available to unlock this device to use it on other GSM networks? (I just bought one and it's on Kitkat 4.4.2 UCUCNE5, and looking for unlock...)

It's only the modem that needs to be flashed. So whatever bootloader you're on doesn't matter.

I wanted to unlock my phone today. ATT website wouldn't let me do it until my contract was fufilled, so I did some web searching.
Started with 4.4.2 and NE5 baseband. Loaded original baseband via recovery, and used the debug menu to unlock the sim. After that, updated the baseband back to the latest. Tmobile sim seems to be working just fine.

Flashing Verizon Samsung Note 10 plus N975U to U1 Firmware

Hi guys I got a Verizon N975U note 10 plus and its stuck on Verizon I'm trying to flash it with U1 so I can pop a sim in and changes it to that carrier. Do I just need to flash it with the U1 file here https://androidfilehost.com/?w=files&flid=297980 or will it need something special the build # is SQS2ASJ8

Can't say for sure it would work on U firmware (lack of first hand experience to verify) as it would for U1.... As long as the phone is network/sim unlocked then you should be able to just put the new sim card in it (and the phone will read the sim card settings and apply them).
Flashing the U1 firmware instructions on flashing U1 firmware have been at link below (bottom of first post). You can get the firmware from that thread also.
https://forum.xda-developers.com/showpost.php?p=80072192&postcount=1
Of course keep in mind that none of this will matter unless the phone is sim/network unlocked. As long as you meet the requirements from Verizon (or the phone was blacklisted for either non payment, lost/stolen or a warranty/insurance exchange that wasn't sent in) then this shouldn't be an issue.

its locked to Verizon at the moment when I put a sim in it will work for a bit then say its not allowed to use another carriers sim at this time.

Either wait until the phone is able to be unlocked by Verizon, or call them and request that they unlock it for you. Until that happens you will not be able to use a non-verizon sim card.
I would also advise keeping the U firmware for Verizon installed and not flashing the U1 firmware, as the Verizon sim/network unlock requires the carrier firmware... At least that is what I am gathering from various discussions/threads.

Is your phone carrier locked to Verizon? Has it been activated on Verizon's service for 30 days? If not, I'm pretty sure firmware flashing won't help anything. I'm on a Verizon MVNO and they wouldn't even unlock it for me to use on their own network. I had to activate with them for 30 days.
However, now that mine is unlocked, it's still locked down to Verizon in a lotof ways. My SIM card for my current carrier can't apply an APN, for example, so I have to do it manually. I'm contemplating flashing U1 to fix that issue (I hope).

I have a very similar situation. I bought a Note 10+ N975U (Verizon Unlocked) and I want to take it to U1 and then maybe to Sprint. I tried to go to the OP here and follow instructions. So I downloaded and selected all the files for U1 and apparently I did the "no-no" and got stopped with the SW Rev Check Fail : abl Fused 2 > Binary 1. I looked at what my phone is on and it is the SJ8 (November?) from Verizon. I'm guessing that means the BL file (bootloader?) in the U1 folder (SGO?) is older than what is on my phone? What do I need to do differently? I already tried without selecting the BL file, but it still gives the same error. Any help is appreciated! Thanks in advance!

The bootloader of the U1 firmware you were trying to flash is lower then what is currently on your phone. So yes you are correct that is the no-no. Also you can not skip the bootloader file when flashing, so that wouldn't have worked.
If you read through that thread you will have found others asking how to go from U to U1 firmware. Also the error within regards to trying to flash a lower bootloader version firmware was also asked and answered. I would encourage you to browse that thread and the Q&A forum because this process has been discussed on more then one occasion... It might contain helpful/useful info for you.
In short you need to get a newer firmware release. Using samfirm or frija apps, or the sammobile website look for the firmware your seeking. Google searching will show you how to obtain samfirm, frija is posted the forum here if I recall correctly.
For U1 the model is SM-N975U1 and the region is XAA.

Need help network unlocking, flashed to stock

I got a new phone, the LM-G820UM AT&T version. I followed this guide: https://forum.xda-developers.com/t/tutorial-crossflash-bypass-opid-mismatched-error.4345963/ to flash the stock firmware. With my SIM card in it says "network locked", it doesn't prompt for the unlock code. I have the unlock code and I've tried the various unlock commands (2945#*71001# and 2945#*20001#), but nothing comes up when I do these. Do I need to get it back to the AT&T firmware to be able to unlock it? If so, how can I do this?

wow, yeah, that's unfortunate. First, yes, it's the at&t firmware that the unlock code works with, not any other firmware.
second, at&t doesn't make their kdz available, so you have no easy way to get back to their firmware.
you might get lucky and find someone who has backed up all their partitions from at&t. Then u would flash ea one back via qfil.
Important lesson: don't buy a locked phone. if u get a locked phone, don't to anything to the firmware until u unlock the phone.
cheers

@AsItLies would this phone work in it's current state with AT&T?

To the best of my knowledge, no. At&t is one of the carriers that has restrictions for their networks. Last I read (have never used them personally), they only allow phones that have their IMEI (they check that), and it's using their ROM, to access volte and vowifi.
so, would it work? yes and no. Volte and Vowifi may or may not be important to you.
Additionally, I'm absolutely no expert with at&t, so u might just try and find out, my info could be outdated.
