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...

hi, i'm new here. i don't know anything about phones. i just switched from at&t to tmobile. i'm using the galaxy note 2 (at&t). with a t-mobile sim card. i got the unlock code from at&t and it is not working. it tells me the unlock network is "unsuccessful" and i've already tried it like 6 times. i'm only aloud 10 attempts. can someone please help me? i know this forum is mostly how to unlock the phone manually, like without the unlock code number.. but i have the code, i just want it to work.. i don't want to root or flash or whatever. i don't even know what that means. can someone please help me?

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.

You do not really need the unlock code. Do a search in the forum as you cam just unlock it with Samsung' service menu.

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:

HTC One X won't accept sim unlock code

I have had two companies give me the same unlock code which does not work. Is it a problem with the phone or a problem with the code?
Both say factory reset the phone but this has some issues I think, sometimes I get a red triangle or it reboots very quickly without resetting from the rom.
Phone is sim locked to Three UK (who have stopped fixing the phone directly and HTC won't look at it as its been boot loader unlocked)
Can anyone help with this if so, give full instructions and files needed. Thanks in advance.
P.S. it would be nice if a debranded rom could be installed.

ARe you on STOCK rom and stock recovery. If no go to full stock

I had the same problem on my One X locked on Orange Romania. It seems some GSM operators change the factory unlock codes. The only way to unlock it would be to have a buddy working at the GSM Operator or wait until the phone gets out of contract. I was unable to unlock mine.

yes I'm on full stock rom.

Does anyone think it is because the boot loader has been unlocked?

It shouldn't, I believe I had the same problem but I was on AOSP, I had to put a stock ROM on for sure.
It could be worth locking it to see though, it's not the biggest pain in the ass!
If no joy, Im out of ideas... sorry mate!
Good luck

My phone has this stock Rom already on it.. I would have to try putting another stock Rom on it. It it possible to put a standard unbranded stock Rom on it instead of HG3?

As far as I know ofcourse you can

OK I have put another H3G stock rom on and this does not work either.
After looking into this further I have found somewhere that if the phone is a replacement one or something was changed from manufacturer and providers with regards to databases for unlock codes then the one provided may not work.
Well my phone went into the service centre and they fixed it but stated after testing they decided to change the mainboard. I suspect because it was originally a CID 1111111 with S-OFF(unbranded as HTC described it) as it was delivered first day they came out. Rush job to get to market and didn't get branded to H3G_001 and S-ON I suppose.
Anyway I suspect that because the main board has been changed the the unlock code has also changed and not been documented or changed on the database for the codes. So they are providing me with the original code not the new one and the letter for the fix state IMEI code previous and new the same, so they must have just reprogrammed that and forgot about the unlock code.
Is there a way to read these off the phone, NVR or something?

I am with Orange or EE and I have tried to flash a stock rom with stock recovery and relocked bootloader and nothing has worked. I have paid 2 companies for the unlock code which is the same code and nothing works I am so frustrated might have to leave htc. This is ridiculous I am on 3.16.61 and my cid is orang001

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???

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

Make my TMobile S4 usable in India...please...

Hi all,
I would like to start off by saying that i dont care about any warranty or any such issues. I had bought a S4 in US which i brought to India without ever activating on T Mobile network. This means that on contacting T Mobile, they are unable to send me any activation code which could SIM Unlock my device.
So now my only problem is to make my device usable. I see two options:
a) SIM Unlock
b) Complete removal of firmware and install some custom ROM, bootloader and other components to get rid of T mobile network
Problem is that i am a newbie and couldnt find any thread that could help me. MY device is updated to the latest version i.e. i am on 4.4.2 with baseband as M919UVUF9B4 and knox bootloader
Can someone help me out. I have already tried rooting the device and trying some apps which suggested that would help me unlock my device but none of them worked..
Thanks

If you paid T-Mobile the full price for the phone approx US$500-US$600 (not the subsidized price) before you left, they should provide you with the SIM Unlock code. You may need to talk with another customer service agent. However, if you only paid the subsidized price, then you've broken the contract with them, and they won't. You'll have to contact a company that will sell you an unlock code.
As to rooting the phone, have you tried this one: http://forum.xda-developers.com/showthread.php?t=2294005 ?
If this doesn't work, you're doing it wrong.

Hi all,
I would like to start off by saying that i dont care about any warranty or any such issues. I had bought a S4 in US which i brought to India without ever activating on T Mobile network. This means that on contacting T Mobile, they are unable to send me any activation code which could SIM Unlock my device.
So now my only problem is to make my device usable. I see two options:
a) SIM Unlock
b) Complete removal of firmware and install some custom ROM, bootloader and other components to get rid of T mobile network
Problem is that i am a newbie and couldnt find any thread that could help me. MY device is updated to the latest version i.e. i am on 4.4.2 with baseband as M919UVUF9B4 and knox bootloader
Can someone help me out. I have already tried rooting the device and trying some apps which suggested that would help me unlock my device but none of them worked..
Thanks

Flashing a custom rom will not allow it to work on a different network. The phone will still be sim locked.
Like the post above me says, call T Mobile and have them give you the code. If you didn't pay the phone off, they won't give it to you nor should they.

Chainfire's Region Lockaway app will SIM unlock in the process of removing region restrictions. I remember reading something to that effect anyway.

For use chainfire's Region Unlock, you must be root.

@Skipjacks & rlichtefeld: I have already tried calling T Mobile and they are not ready to provide me any unlock code since the phone was never used on the network. Yes, its paid in full but i am in India now and cannot do much from back here to fight with them.
Have already tried chainfire's Region Unlock but its unusable on 4.4.2.
Please suggest the ways in which i can unlock my phone which is on 4.4.2 with baseband as M919UVUF9B4 and knox bootloader and i request you to please do not assume that phone is blacklisted or the warranty be void. i just want my phone to work here and that's it.

id suggest you find a website that unlocks phones, it usually costs less than 10 bucks or probably like 500 or so rupees but it should save you a lot of headaches

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.
