ISSUE with the unlocking code - AT&T Samsung Galaxy Note 4

Hi there, I have an AT&T Galaxy Note 4 with android version 5.1.1
So back in August AT&T have provided me with the unlocking code which did unlock my device. Then two months after, my charging port has been damaged so I sent it to Samsung to get it fixed which took a month for them to get it fixed. Then they sent me back the phone after they changed (cosmetic parts, LCD screen, USB cable, charging port) even though the only issue i had was the charging port. Long story short, I got the phone back from Samsung updated from 5.0.1 to 5.1.1 but the device was locked to AT&T network.
I made a request again from AT&T for the unlocking code, but the code did not work. when I put in the unlock code it says "Network Unlock Request Unsuccessful"
The IMEI number did not change so I have no idea what to do since I talked to AT&T and they told me the only unlock code for the IMEI number I provided should do the job.
Then I tried to call Samsung and they said there is nothing that they can do, my only option is to sell my phone and buy another phone that is unlocked ????? please I need some help here. I tried Factory Reset but still no luck.

Experiences SIM unlocking SGH-I747 (Galaxy S III) AT&T 4.3 with codes

Has any one had positive experiences with SIM unlocking the AT&T sgh-i747 (Galaxy S III) after the 4.3 update with a code??
I paid $14.99 to SamMobile to unlock using their software but it didn't work and they don't answer my emails. But that's not with a code
Admins: if there is a thread for this already, please point me to it. I could not find one with successes after the 4.3 update
Note that AT&T didn't want to give me a code: I had cancelled the service already and paid the ETF (foolish, I know), and now they don't care about me
I've seen plenty if users have success unlocking with a code. I don't know about how sammobile does it though.
You have to be stock for it to work BTW.

Thanks doc. By "stock" you mean the official ROM without root? As I said, it's not the original version (4.1.1) but the OTA update to 4.1.3 by AT&T
I will have to buy some code
Root doesn't matter. Many custom stock based ROMs will also work but some may have removed some needed files which is why I just said stock. As long as its stock based and has the stock dialer it should work though.

So, no one has any experience to share? has anyone unlocked a Galaxy S III 4.3 with a code? It's OK if you prefer to PM that info to avoid being interpreted as advertising
Official AT&T Unlock Code Fails
My contract ended id-September so I requested an unlock code, which was previded (below). I sent two separate requests for the unlock code and the number provided twice matches. I tried the unlock code (while using a T-Mobile SIM card) twice and the phone said the code was incorrect.
I prepared the phone by doing a factory reset. These are the phone details:
Model number
Samsung-SGH-I747 running
Android version
4.4.2
baseband
I747UCUFNE4
kernel
3.4.0-1514807

These are the instructions provided:by AT&T:
Thank you for contacting AT&T Customer Care about unlocking your AT&T Mobile device. We have reviewed your request and confirmed that the device may be unlocked. You should complete the unlock process before porting out your number for use with another carrier. Please allow 24 hours upon receipt of this notification to complete the unlock process.
Your Unlock Code is :12345678
Unlock Steps - Use Non-AT&T SIM Card
1. Power off the device and insert a non-AT&T SIM card.
2. Power on the device.
3. Network Lock displays: Enter the device unlock code.
4. Enter the eight-digit unlock code.
5. Press OK.
Note: You are allowed five attempts to unlock before your device permanently locks to the AT&T network. Note: If your device has been altered from the original manufacturer's standards, such as rooting the device, your unlock code may not work and you will need to contact the original manufacturer for assistance.
For questions regarding AT&T Mobile device, please visit the Phone/Device Learning Center. Thank you for your business. For other questions about our AT&T wireless service or other Mobile devices, please visit att.com.
I've tried the unlock twice and it did not work. The phone is rooted. I think I manually installed 4.4.2 because the OTA failed many time to update.
I think these instructions are confusing in that step 3 and step 4 both say enter the unlock code. Is there a second code? I thought an phone unlock code is a single 8-digit number.
I have successfully unlocked an old HTC Aria so I have a little bit of experience performing unlocks. But if you have advice I'd appreciate hearing your thought.

Forgive me for asking but is your phone running a stock ATT ROM? Does the imei obtain from the phone match the imei on the label under the battery?

Yes, the IMIE shown on the label and via About device --> Status are identical. I asked AT&T twice for the unlock code because I thought maybe I sent the wrong code. I'm 99.9% sure the IMIE number I used is correct.
Yes, the flavor of Android installed is the AT&T version. If I recall, in August 2014 I used ODIN to manually install 4.4.2 because the over-the-air update was not working. (The OTA would download but fail to install. I'd wait for two or three days before I could try a second, third, forth... time.) I have also done a reset via Accounts --> Backup and reset. The MicroSD card was erased too, through the reset process. The lock screen, the home screen, all the typical AT&T add-on applications seem to be as they were when I purchased/upgraded the phone two years ago.
4.4.2 is rooted and I have Chainfire's SuperSU v2.00 Pro installed.
I should mention this: When I look at About device --> Status, all the way at the bottom, is "Device status" which shows "Custom". This isn't a setting. I suppose this is why the network unlock code is not working.
I'm not sure what to do next. I can't recall the page on XDA which guided me through the install of 4.4.2. I'll look a little harder because I'm sure I used XDA as my guide for the upgrade. Perhaps I'll try to install a non-root 4.4.2 image.
I never expected that I'd have five and only five tries at network unlock. I've used three tries... I need to make sure the last two work! Any advice is appreciated.
Sorry, I'm out of ideas. All I can suggest is flashing back to completely stock with stock recovery and no root access.

In my case AT&T told me they would not give me a code until I paid off my contract. I would seem they don't care about their former or current customers.
I showed them though, I was still on 4.1.2 and simply donwgraded my modem and used the free unlock method. It's now time to upgrade to kitkat.
@wpscully
Don't know if you still need help, but maybe this would do the trick? I think it's the last post that's describing a different method of getting the unlock code to work.

@DocHoliday77, your pointer you mention above has proven invaluable. For the record here is the link I used; http://forum.xda-developers.com/showpost.php?p=55677344&postcount=137 MrBrown72 has a secret code and menu selections which seem to tell my phone to ignore all the customizations I made (root, maybe removing some AT&T bloat) and accept the valid network unlock code AT&T provided when my contract ended. The phone is now working on T-Mobile, rooted still, and none the worse for wear. I also want to thank Audit13 for advice on what not to do, and well as his guiding me so I found the hints that the phone considered itself "custom".
Finally I'll mention that if I had not been able to unlock this phone I never, ever would have selected AT&T as a cell provider. In this process they were professional, respectful, and helpful. T-Mobile didn't get my old line transferred before my AT&T contract ended. AT&T probably could have made clearing up this transfer very hard. But they were kind, understanding and efficient in reinstating my old number briefly so T-Mobile could finish the transfer.
I know others have had trouble with vendors. I wish all companies could understand that being unhelpul or rude is the fastest way to lose a customer for life.

[Q] Pls Help! Need to determine unlock status asap. Also, USSD codes failing

Hi.
I am unsure if my phone is unlocked and can proceed with porting my number over to Metro PCS. Please help me with advice how to proceed. I decided to move my service to Metro PCS since they are now a Tmobile company and after lots of research, I found that I can use my current phone/software as long as it was unlocked. I recently purchased my Galaxy s4 second hand and assumed it was not unlocked. I had immediately rooted it and flashed a new rom (Insane Kitkat 4.4.4). The phone has been working well. I already have requested and have my unlock code from Tmobile.
When I went to the Metro PCS store to port over my number, the phone did not request an unlock code when inserting their Metro PCS sim card (not activated). They said that my phone may already be unlocked or that it may not need to be unlocked since Metro is now owned by T-mobile. They stated that it may work if they go through the entire registration process, port over my number and activate it but that it would be a gamble. If it did not work, then I would not be able to go back and reactivate my sim immediately with Tmobile since it would then be in deactivated status with them.
I tried to find out if it is already unlocked by *#7465625# but my phone will not run this or any other USSD codes to verify. I keep getting errors when trying any USSD codes. A message says 'USSD code running' then "unable to process request".
A friend of mine has an activated Galaxy S4 on Metro PCS and I tried inserting her sim card to prompt for the unlock code but my GS4 just booted normally then showed 'not registered on network'. It did, however, have cellular signal bars. When I inserted my Tmobile sim into her GS4 it did ask for the unlock code normally.
I am at a loss now..
funny, I like to know if there is a way to check carrier unlock status for simcard without having to put a simcard in.
T-Mobile phones work with metropcs without the need to unlock
Could the custom rom be suspect?
Maybe need a stock rom to get carriers sorted out, then go to custom roms.

I ended up contacting Tmobile and they stated that the phone showed unlocked status already but I think you are correct. I wasn't aware they could tell me this. It was very fast and super easy to find out.
I have the phone working great on Metro PCS now. USSD codes still failing though...

When you mention sim unlock code, are you referring to a code to unlock the sim or carrier/network unlock code?
I've never personally come across a situation where a phone re-locked to the original carrier after unlocking with a code or using a free method. This includes flashing ROMs, bootloaders, and modems to an s2, s3, s4, note 2, note 3, and note 4..

The quickest solution may be to buy an unlock code from eBay. Unlocking by code should be permanent.

Carrier unlock for S7 Active

Good day, I bought this device to use overseas it have clean imei. But when I put my own Sim card I found that it's carrier locked. This phone is not on contact so I headed to https://www.att.com/deviceunlock/#/unlockstep1 to unlock it. For what I received reply -
"We can't unlock your device today. You've tried to unlock this device too many times. Wait 30 days and then try again." So that's what I did receiving the same decline afterward.
When I called at&t support line they said that this imei is not listed on the AT&T database and that phone should be from another carrier (although it has an at&t logo on the back side).
Desperately I tried to use third-party websites like https://www.unlockbase.com getting error again - NO TOOLS FOUND TO UNLOCK YOUR Samsung Galaxy S7 Active!
Any solution on how I can use this phone with another carrier?
Any software unlock? I will root it for this

Unable to unlock Samsung Galaxy S9 T-Mobile model SM-G960U

I have been trying to unlock a Samsung Galaxy S9 T-Mobile model SM-G960U to use it on local carrier (Ecuador) with no luck (I have use doctorSIM service too)
After booting the phone a got a message:
Security error.
This phone has been flashed with unauthorized software is locked. Call you mobile operator for additional support. Please note that a repair/return for this issue may have additional cost.
Trying to use the T-Mobile device unlock app, then a screen shows up with a message "Your device is network locked at this time, which prevents it from operating with other compatible wireless networks. To inquire about your device's unlock eligibility please continue" but after tapping the Continue button there is not option of permanent unlock, I got a message saying: "Server not responding. Please try again later."
I have trying to install de stock firmware G960USQU7ETG3_G960UOYN7ETG3_TMB (Android 10) downloaded from Frija using the Odin tool, doing a factory reset, wiping the cache, doing a NAND Erase with Odin, but the security error still shows up.
The device is able to browse on websites using Wi-Fi, what should I try next?
paid services are the only way. You won't get help on that here. They employ a different type of lock than most devices.
@OP
I don't know all the ins and outs of tmobile unlocking (not a fan of their service). However, I recently had in hand a paid off s9+ which was still locked. I ran the unlocking app multiple times over the course of a few hours. Each time it came back with an error (unsuccessful or something to that effect) when I tried the permanent unlock. For each attempt the tmo sim with active service was still installed. Eventually it did finally unlock. I'm not sure if a tmobile sim with active service is a necessity. Probably is as it has to authenticate the account for unlock eligibility.
I have a Verizon Samsung Galaxy S9 Sm-g960u and needed to switch to T-mobile. I had no problem switching from one carrier to another because I was told that all Samsung Galaxy S9 devices came factory unlocked. I bought a T-mobile Samsung Galaxy S7 Note from a friend and tried using the T-mobile app to unlock the phone I think there was a problem so he just called T-mobile and explained that he sold his old phone blah blah blah and since he owned it they just unlocked it right over the phone, no problems or issues.
