[Q] Stock Note 3 lose Unlock after Sent back to Repair

Hi to all
I have a Stock AT&T Note 3 on KitKat, And I bought the unlock code from a website and the Code was working fine
I sent my phone to the Samsung repair center in TX to fix the memory card slot problem.
After a week they sent the phone back to me, and Of course the phone is back to the original settings
When I turned on the phone and inserted my T-mobile Sim card, the phone is asking me for the network
unlock code, so I entered the same code that I used before and it is not working ...
Thanks

You probably didn't get the exact phone you sent them. They probably sent a different one. Check for an old receipt, or the original box for the imei code. See if it's different then the new one. It most likely is. If it is, you will need to obtain a new unlock code.

I checked the IMEI number and they matched
I also thought of that it might have to do with the unlock code
so I ordered another Unlock code from a different site
and it turned out to be the SAME Unlock code from the other site !!

Yes there's only 1 unlock code per imei. It doesn't matter where you obtain the code, it will be the same.
I hate to tell you this, but you'll need to contact the warranty dept and probably send the phone back. Again :'(

Do you think this has anything to do with the Region lock restriction ?

No I don't believe it to be related to region lock.
Check one more thing for me please. Verify that the imei of the phone is what you believe it to be. Open settings and in "about phone" check under status and verify the imei is what you think it is. You can also Press * # 0 6 # on your keypad, Press 'Call' or 'Send' as if making a call. Your IMEI number will be retrieved and displayed on your screen.

do you know anything about this ?
NOTES: If you have a Samsung Galaxy S3, S4, Note 2, Note 3 or your Android version is Android 4.4 (KITKAT): All SAMSUNG devices manufactured after the date of JULY 2013 and Samsung devices running on Android version is Android 4.4 (KITKAT) are subject to REGION LOCKING. If your phone has been used previously with the original carrier, this will not apply to you. However, if your device is BRAND NEW, your must activate it with the original carrier. If your Samsung device becomes Region locked, you will not be able to fully factory Unlock your Samsung devices so it can be used internationally. Even the correct code will not work anymore. In order for your Samsung device NOT to be region locked, you MUST activate (FIRST USE) your S3, S4, NOTE 2, NOTE 3 with your ORIGINAL carrier at least ONCE to take your region lock OFF. After your Region lock is off, you can Sim Unlock your device via Unlock Code. All Canadian Carriers are NOT subject to Region Locking. All USA and European Carriers ARE subject to Region Locking. Region lock is removed automatically after you activate your device with its original carrier. Make some calls before unlocking. (Insert an active original sim card into the device and make a few calls to activate the phone and bypass the region lock. Once you've activated the phone, you can input the unlock code.)

Well after reading that I'm amazed. I believed region lock was based on where you lived and used the phone. Like a person in Europe couldn't use an at&t phone overseas until it was used in the states. I was unaware a person in the U.S. had to do the same if they were using it in the U.S. but with a different carrier. My apologies.
You wouldn't happen to know anyone on at&t would you? Maybe a Samsung rep in bestbuy can help you with borrowing an at&t sim and making a call or 2 on your phone.

I tried to use someone's ATT sim and it doesnt work
Also Samsung is telling me that "as you have unlocked the device from third party site , and this is not considered as official unlock for the device"
I might bring the phone to bestbuy and let them check it out.. since the phone is still under Warranty

There's defiantly something wrong if an at&t sim doesn't work. Are you the original owner? If not do you know the original purchaser? It could have been blacklisted.

The phone is working Fine with an ATT sim card, it has signals
it is just that it is not working after I inserted my tmobile sim card
and entered in the unlock code... So the imei should be fine !

I believe you need approximately 5 to 15 minutes of use on an at&t sim card from my previous readings of other user experiences.

Sprint device SIM unlocking

I got a Sprint locked N950U device today from a third party, that I'd wish to unlock to work with any (international) carrier. I checked the IMEI and it's listed as clean. However, when I put a t-mobile card in, or a European SIM, and restart the phone I don't get the 'Enter network unlock code' dialog. After the OTA update I do get Sprint OMADM notification about trying to register the phone on the network, but since I don't have a SIM plan it fails. Do I first have to have the phone running registered on Sprint (or MVNO?) and then can switch to another carrier?
Also, when I go to at least two unlocking services online, and enter the make and model of the phone and IMEI, I never get an e-mail with unlock details and the form submission button just keeps saying 'Please wait'.

For Sprint's registeration/activation nag, have you tried disabling the responsible packages using an app like Package Disabler? If not, do that and see if still getting the unlock message. Worst case it will at least take care of the other nags. If you still get the unlock code message then try contacting Sprint to unlock. If you go 3rd party service, I've used cellunlocker dot net before.

i found samsungphoneunlock they unlock my note 8 from sprint via remote connection, someone has connected to my laptop and i follow some instructions and they unlock the phone for me..they told me sprint phone do not ask for code..i hope this helps..cheers

N950f-ds [galaxy note 8 exynos] - rmm state lock

Hello,
I negotiated a Galaxy Note 8 (SM-N950F/DS) through a site of collective purchases in Brazil, with invoice and all the accessories.
I did all the tests in the device and I decided to buy it, because it seemed reliable.
The device already had the factory settings, but with Android 7.1.1.
I activated automatic update in order to upgrade the android to 8.0.
I received the update and installed it. When restarting the phone, I started the settings normally, I was able to configure the Samsung Account, but when I was starting the configuration of the Google account my phone blocked.
After trying several unlock passwords, I made contact with SAMSUNG which instructed me to send the device for local service.
When I arrived at the service it was verified that my device had "transport block" and who is responsible for unlocking the device is the store in which the device was purchased.
I went to the store that was described in the purchase invoice and there informed me that the store does not perform any kind of unlock or block, so I could not solve the problem.
After several discussions with Samsung and the store, it was verified that my invoice was exchanged and that it was possibly not true.
It was from there that I realized that I was deceived by the seller of the device, because when I try to contact him, my calls do not complete and he blocked me in the social networks.
The only information I have about him is his name and the phone number that should have already been discarded.
Anyway, I realized that I would have to try on my own. Because of this, I am doing this post. I apologize for the long text above before passing the technical information, I had to explain what happened, because I do not want to pass as a thief.
After doing several research I found that the lock was being triggered by RLC.apk which is located at "/system/priv-app/Rlc/Rlc.apk" in stock firmwares.
I found an instruction that guided to freeze the performance of this app with application Ice box v3.1.9.1.
I tried the instruction, but it did not work on devices with Binary 4 (which is my case). The device continues to locked.
I talked to some technicians who told me that this is a block known as SEDA_LOG or DNP 0001. There are some companies that unlock remotely, but it does not have support for Binary 4.
With rom COMBINATION I can use some applications installed by adb, even my data network works perfectly.
The IMEI is normal, unlocked, and is out of the blacklist.
Other information is that the RMM State is Lock, FRP ON, OEM LOCK ON.
Also, when the lock screen appears a few times the message "Silent Log is not allowed for commercial version, please get the EM token".
Through the Samsung Account I can make the phone ring and even locate it, but it does not unlock.
Some failed attempts:
- flash a rom from another region (the device region is ZTO, I tried O2U)
- wait 7 days for the RMM State to disappear (not disappeared, continued locked)
- freezing the RLC app
- enter several PINs to try to unlock.
- login with my samsung account on rmm.samsung.com to try to unlock rmm, but I can not access.
If anyone can help me, or can guide me in what to do, I am very grateful.

Well, if you got scammed by some nasty person, strictly talking, the device in your hands was illegaly traded, as such, here in XDA no solution will be given or support offered, sorry, these cases appear often, and the moderators usually close the threads

Carrier Sim lock after Samsung repair

So I bought a Sprint Note 8 (SM-N95OU) that was unlocked from eBay over a year ago. We use T-mobile for our service. Everything was going good until the phone would no longer boot up due to draining all the way to 0%. Called Samsung and they did a free replacement outside of warranty.
So now that it's been repaired it is UICC SIM carrier locked.
Under UICC unlock it says "your device is locked to Sprint SIMS only." A message pops up and says to contact sprint. I contact sprint and give the IMEI and they said I have to contact the owner. I assume they never unregistered it from their account.
Is there anyway we can go back to using the phone? I mean we paid for it and feel like we own it but according to the software it does not seem to be the case. Lol.
Will putting a Sprint SIM in unlock It? I notice it doesn't ask for a pin and I think I read they are unlocked via a signal. That signal would have to be resent or would communication on the Sprint network alone unlock it. Not sure If somehow it will know to unlock itself once it connects to sprints network?
Anyway any help or direction is appreciated. Not sure if I need to sell it to a Sprint user and get a different phone now.

Well I just paid somebody on eBay 10$ to unlock it. So far so good.

I had a very similar situation whichresulted in weeks of back-and-forth communication between Samsung and Sprint advanced technical support. Which that department is a joke in and of itself but the actual solution to my problem was just to insert an active Sprint SIM card into the device and then have them unlock it.

Question Verizon S21 Ultra Locked and not unlocking

I appear to be in one of those samsung lock horror stories. I purchased a paid off verizon s21 ultra that was suppose to be unlocked but after i put my tmobile sim into it works for 5 minutes perfectly then an error pops up saying unable to change carrier call verizon customer support. So i did long story short i got no where. So i filed an FCC complaint and got in contact with a verizon executive and he got in contact with who i bought the phone from and they provided all the paperwork proving it was paid off and he reprocessed the unlock request and said it will now for sure be unlocked and it didnt unlock so i contacted samsung like he said for me to do if it didnt so i did and they told me to wait 48 hours for it to process. 48 hours later guess what its still not unlocked so i call samsung back and they said verizon still hasnt released it supposedly and there is nothing they can do and i need to go back to verizon. Im stuck in an endless loop of verizon executives telling me to call samsung and samsung telling me to call verizon.
What is there left for me to do now? This is stupid why is it not unlocking... The only thing that i can think is left is that the phone is flashed with stock firmware and not verizon firmware to remove the bloatware. But that seems like it shouldnt matter. Also the phone never asks for an unlock code it just says call verizon customer service.

It's more a Verizon lock horror, not Samsung.
Flashing other FW won't solve your issue.

First, did you verify that the unit is paid off?
Second, do you know anyone that has verizon?
Don't know if it will work, but I would try flashing the unit back to stock Verizon firmware and finding someone who has a verizon sim card.
Verizon units kind of unlock on their own. It is troubleshooting I would try because I do not believe the unit will unlock on U1 software on its own. Once it can get unlocked then flash back.
I suggest someone who has a verizon active SIM as it may help in it unlocking even though you can connect through WIFI

The verizon executative said it was guaranteed paid off and he unlocked it remotely again. But it does have u1 firmware on it im guessing i need to use frija and download the vzw firmware? And will another unlock request need to be processed again? And none of my friends have verizon due to how much of a ripoff they are lmao but i can have another verizon demo sim put in at another verizon store. I feel like i would have to file anpther fcc complaint just to talk to another verizon executive.

I believe for it to be unlocked or at least go through the process, the verizon U package is what I would flash, but you may be in a little bit of a issue if you don't have a verizon SIM on hand, even if not activated.
There are multiple ways to get it to flash back to U. I would use a patched ODIN and just flash the appropriate files from somewhere like samfw.com
If he sent out the remote unlock, it is very possible that once you flash back to U verizon package and connect to WIFI and go through the setup process etc. It may just unlock on its own. If you do not have a Verizon SIM card, leave your SIM out of the phone while going through the initial setup. You will need WIFI.
I would start with a clean flash just to be safe.

You literally quoted the answer

Verizon firmware has an app called "Network Unlock". Perhaps at the 60 day mark, the phone automatically unlocks. However, if on the unlocked U1 firmware, there is no framework to remove the lock. It'd be interesting to see exactly how the Verizon unlock process works.

It is somehow tied into their U package software and I am assuming unlocks it at the modem level in background processes. It's like the "signal" they send out can only be detected on their U package. I've seen it many times where Verizon phones automatically unlock themselves when restored to original package from U1.

I can confirm this works on my s21+ that was on verizon network, and was supposedly networked unlocked. Service carrier software said vzw/vzw, vzw/vzw. Tried to switch to tmobile with no luck with sim card swap. 5 minutes, error message about cannot which carriers, please call Verizon. Was on SM-996U1. So I tried to flash to SM-996U1 TMB, then SM-996U1 VZW, then, SM-996U1 XAA. No luck. Then I flashed, hesitantly, with SM-996U VZW . I thought that would put all verizons bloatware on it. Reseted phone and it did put all verizon bloatware on it. Then the magic! I installed my new tmobile sim, and a message appeared and asked if I wished to switch carriers. YES!!! phone rebooted to tmobiles network with no verizon errors. I checked service carrier software and it was TMB/TMB, VZW/VZW. I flashed phone again to SM-996U1 XAA. I rebooted and service carrier software was TMB/TMB, TMB/VZW! I then checked for software update, took update, and all it good! Thanks for all the information here. Took me days to find it and understand it and try it!!

Hi, folks. I am facing the same issue with my S21 5G (SM-G991U). I am also told that the phone paid off and clean. I am not sure what version I am on currently. I have tried SamKey, but that didn't work. Any help would be appreciated. Thank you in advance.

From my experience, Verizon phones will not unlock unless on the U package, the U1 never allows the unlock to be processed.

It does not boot up with Verizon but it does have a few Verizon apps included (it has Call Filter and Digital Secure) installed. The current version of the software is G991USQS6EWD5. Service provider version is SQOMC_SM-G991U_OYN_SPR_13_0020 SPR/SPR,SPR/VZW.

Are you using this phone with Verizon service? From info you provided, your phone thinks you are using Sprint. It's a SPR CSC. You need to change the CSC to VZW. You need to bring the phone back to it's original state for any attempt of the unlock "processing".
