A few days after updating my phone to Nougat, my phone restarted itself, and after the restart, a security error showed up saying "This phone has been flashed with unauthorized software and is locked", and after unlocking the phone a screen came up saying that my device has been network locked and it can be unlocked using the device unlock app, and the invalid sim card error.
I was never rooted or anything like that, my phone had received OTA updates. I did not master reset, but I rebooted many times, and the error message appeared on every boot, but disappeared after a while allowing me to use my phone. And now, although the error doesn't seem to appear anymore, i still can't use my network, and when I checked the IMEI, it had changed to 350000000000006, and the one on the back is different.
Is there any possible way to fix this without sending this phone back to Samsung/T-Mobile for exchange, because I had bought this phone from USA but brought it to Pakistan, and Samsung Pakistan says that they would charge me for the repairs ( I still haven't visited them, they told this to me through mail).
HELP PLEASE?
Bump?
Have you tried using Samsung Smart Switch?

I didn't try Samsung Smart Switch, but I had reflashed it using Odin, and tried a factory reset and it didn't fix it, i got it fixed through Z3X box.
This happened to me also.

I had taken in to a repair shop who had a Z3X box. That's the only way to get it fixed. He downgraded my phone to Marshmallow and re-flashed the cert. I live in Pakistan and that costed my Rs.1000 (i.e. $10). Make sure you take your phone's box with you as a proof of purchase because changing IMEIs is illegal in many places.
P.S. I can't upgrade to Nougat now, if I will, the phone won't register to the network.

Thanks mate. I also live in Pakistan - Lahore. I took my phone to Hafeez center and they charged me 1500. Now the phone is on Marshmallow. I'm receiving notification of update. I've tried 3 times but if failed to install. When I tap on update it downloads the OS which is about 1.3GB. then restarts to install but it fails when reaches 30%.
Can you please tell me why we can't update our phones. I'm using another s6 which is also of T-mobile and it's running fine on nougat.

Not sure about that but we can't update because probably our CERT files have been patched in EFS is messed, I got it done back in July 2017, and at that time, the guy who repaired it said that they didn't have Z3X's software update for Nougat, so they had to downgrade my phone to Marshmallow, and the patch they used won't work on Nougat. Don't know about yours though, maybe he used an updated patch or a different tool, you can ask that guy whether if its safe for you to update to Nougat or not, if he allows it, then try flashing Nougat through Odin, if it doesn't work you'll have to get it patched by him again. Don't update if he doesn't allow, otherwise he won't patch it again without extra charges, and if he allows that and something goes wrong you can blame him for that

Bump,noone on metro pcs has had this issue?
i have the same issue after updating to the latest android version 6.0.1
I contacted customer service but their operator won't let me talk to "that someone" it will just end the call on me even though bills are paid on time. They have the worst customer service . I went to the store where i bought the phone and they told me chat online !! They don't even have one
****.. so it was the update after all. I also updated to MM, and then the sim unlock tool would always fail immediately.
I called Metro PCS several times, they can't help me.
We need to go back to Lollipop to get that sin unlock app running, but it seems it's not easy to do this.
So I wrote a guide, thanks to @GotHeart 's advice.
Follow this guide and you should be able to downgrade to Lollipop and run the stupid sim unlock app.
Baseband: N950USQS3BRA8
Note 8 is unlocked and currently with T-MOBILE, previously AT&T. I've search all day today and still can't find why I don't have the Oreo update yet. I have the Samsung keis software and it tells me I'm up to date. Did it ever come out for my baseband? I apologized in advance if this was already talked about, I only saw discussions about it being rooted. I want to keep it stock. Thanks

You can check for latest firmware related to your specific model on sammobile.com, then download through updato.com (or using the SamFirm tool) and flash it through Odin.

Since you're using it with T-Mobile and it was previously AT&T you're not going to get updates anymore unless you use an AT&T sim card.. The only way to get the updates at this point is to download the update firmware yourself and flash it through odin. The reason being is because T-Mobile doesn't carry AT&Ts firmware updates so you have to get it yourself.. It's easy as hell to find the firmware on places like Android File Host. Also do not download T-Mobile firmware it will not flash... Use AT&Ts firmware only.
I have a AT&T iPhone 7 from work, you guys think if I take that SIM and put it into the Note 8 the updates would come through? I was looking through the Sam mobile thing. You guys make it seem easy to manually update and I'm terrified being my first time doing it that way. But if you think the SIM card swap would work I'll give that a try first.

The sim card swap should work.. Can't hurt, try it and then check for updates.
It worked!!!
I swapped out the sim cards and it worked!
I ended up having to back up the device and restore, since the update wasn't showing up. I cleared the cache, checked and nothing. After restoring the phone the update became available. After the 8.0.0. update there was about 4 updates after (security patches). I'm now on 8.0.0 with Aug 2018 security patch. I put my tmobile sim card back in and restarted the phone. I even get the tmobile screen during boot up which I never gotten since I switched back in February. All in all it's working fine. I'll update if anything crops up. Thank you all for your help!
You can push software update with this procedure.
put this in your phone app: *#8736364#
Then go to Field Test mode.
Change "Device Initiated date" to one or a few minute ahead. wait until you see "SET" then press Home.
Wait until you see software update to kick it.
Try several times if it doesn't work at first.

Hello,
I have an SM-N950U from TMB which was purchased direct from Samsung when it was just launched after the whole debacle of the Note 7.
Phone has been working fine on TMB this whole time. Today I switched to VZW and attempting to have the phone unlocked.
I tried to use the Device Unlock app on the phone, with no luck. It fails when I try to Permanently Unlock the phone.
I called TMB for assistance, they said that the manager has tried to process it manually and has been unable to do so after multiple attempts. Escalated to higher support who got on the phone and said she's unable to help and does not know why it is not working. Said she will be escalating to a higher support group, but as of yet, nothing from anyone.
Is there any way of unlocking this phone without TMB?
I've attempted to flash VZW via ODIN, both U and U1, with no luck. I also tried the U1 XAA and still the same thing, I get a message "Network locked SIM card inserted".
Any help would be greatly appreciated as I am at a total loss and want to continue using this phone as I've been, just with VZW now.
Side note, maybe it's failing because the phone is already unlocked, just doesnt work with VZW? Not sure if thats a possibility, but is there any way to check to see if the phone is in fact unlocked or not?

Who is your provider? Are you using SIM or eSIM? Are you rooted? Did you disable all the Magisk modules before the update? If you forgot that step, have you since disabled all Magisk modules and started over?
While you may be out of commission on the phone side (although, Google Voice would be a good band-aid), you may not be out of commission on the SMS side. Google's text app, Messaging, recently went live with RCS messaging and it can send texts via WiFi.
Incidentally, if it's Google Fi that's giving you fits, the same thing happens to me every time I do a clean install. Fi refuses to connect until I've rebooted two or three times and then the final confirmation comes several hours later.
im in malaysia bought secondhand 1 year ago on grey market , check my sim with another phone , working well on that phone. had been running my phone on regular stock since bought.

Okay, you answered almost none of my questions but it's irrelevant at this point because it sounds like the phone was stolen. If the IMEI is reported as stolen, it's flagged in a database and alerted carriers will shut off the service.
If that's the case, at this point, I'd be more concerned about the police knocking on my door than lack of mobile service. I'd send you over to IMEI.info to verify but I'm guessing I haven't told you anything you didn't already know.
imei number legit not reported or blacklisted, but yeah i think this phone is doomed unless there some magic update resolved this

Why don't you try to reset using the last official 10 firmware (to reset all partitions), then activate through setup, then flash and test a custom rom. This is of course only possible if it's an unlocked bootloader (which you didn't mention) but that's where I'd start especially if it worked before the update. You say is legit and sounds like it worked BEFORE the last update so roll back and then use a custom rom.

Unfortunately it's my best guess because I can't reproduce it myself but if it worked prior to the firmware upgrade, it should work by reverting the firmware to the previous firmware in my opinion. I'd take it the step furtherand go with a custom 10 ROM to remove Google firmware updates messing with it in the future (assuming we get it working again).
Interestingly enough, I searched other forums and found other users reporting the same issue. Again, assuming it worked on the previous firmware, I would roll bak to it. Ideally, I would rollback to 10 because I know 10 works (not sure how well it works for you in your local and provider), but thats where I would start. Backup everything you need, then use the last 10 firmware to -w the device and activate then start over.

Hey guys,
I searched on google but was not able to find a solution for my issue due to software updates..
For like a week i do have the notification for the software-update to be ready to install (October security patch) and finally yesterday i had time to let the installation do its thing.
All of sudden after the update i can enter my SIM pin and that's it. No network, no cellular NOTHING.
What i did:
- Factory reset
- Data wipe via recovery
- Flashed current DBT firmware manually via ODIN
- Flashed previous DBT firmware
I am out of ideas.. Seems like a hardware problem, right? The lower part inside of the phone - is that the part for network? Should i try to replace it?
I replaced my screen 2 months ago, therefore i am out of warranty i guess, right?
Thanks in advance for any advise or help.

To decide if you still have warranty or not, you need to visit the sales/service centre. To ascertain your issue, you need to give a little more background on your last activities. Did you change your CSC anytime? When the problem first occurred, were you totally stock? Is your device carrier locked? Lots of questions..
Look if able to see IMEI in device settings - about phone
If IMEI is there and still you are unable to connetc to network, you should ask your operator if your IMEI got banned.

Hey Doc, thanks for responding!
Well, both of my IMEIs are there. I use dualsim and both of my cards accept the PIN and also shows the IMEI but on both of them no signal. This first happened after replacing the screen. I forgot 1 or 2 screws and then i had no signal. After screwing correctly, i again was able to connect to the network.
And now all of sudden immediately after updating OTA both of my sims stopped working. But well, i have seen some youtube videos saying, that it can be the GSM cable on the side of the phone. I am not sure if i replaced my old cable with the one in the new screen or if i used the old one. I will check later when i am at home.
My only guess is: GSM cable is dead, motherboard died or flex cable is damaged..
// Edit:
I removed the GSM Antenna from my old display and replaced it with my new screen. For a second i had 4G and it died again.. i took out everything at least 5 times and finally i cleaned everything with Isopropyl-alcohol and let it dry and voila my phone has signal again. No clue if some miracle happened but i am happy again.
