Security Error and Network Lock

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

Hi,
It looks like my phone's region was set to Singapore (XSP). Both the SIM cards I use are for Canada. Is there a way to change the phone's region?

as stated before, just flash another n960f firmware manually.
so try OXM
single sim and dual sim have the same firmware in case you were wondering.

Thank you and I know I'm asking very basic questions here, it's just so simple with a Pixel and I really don't want to brick the Note.
What you are saying is that it doesn't matter the region I pick, the Note 9 will continue to work as an "international" phone where my two Canadian providers and Google Pay will continue to work? I have XSP right now as region so if my phone is set to Singapore and I can use Google pay in Canada, one doesn't prevent the other from working.
I can also see that versions ending in "ARJ1" are available from samfirm and the "J" would mean it includes October patches if I understand everything right.

familiarize your self with what is a snapdragon and an exynos and the different phone models pertaining to each then bricking won't be an issue. anyways ODIN usualy wont let you flash something that is not compatible.
yes J is October and for google pay, usually its supported pretty much wide spread. samsung pay is an other story and is the more coveted of the 2 'pays'. but since you're after Google pay, it should still be working.
just remember that you cant downgrade bootloaders so be sure of your intentions because you cant revert back to a lesser revision.

Thank you, that's a very good point. I know Samsung can be slow to update to begin with so I was looking for ways to be at least not in a situation where my phone is the last to get the slow updates. To have an expensive flagship phone that still can't apply the September updates is disappointing. I have manually flashed my pixel often because the "check for update" would not give me an update so that's not usually a problem for me. I also liked how the pixel has very few customization options compared to the Note 9, that's fewer options to reconfigure after a fresh flash!

I applied the update from today (in the stock firmware thread) and I was a bit concerned as this was a first flash but everything went well. I have to say as nice as it is to like a phone "stock" like the pixel, having customization option is good. Also it will discourage me from doing full wipes all the time because it takes more time to reconfigure!
Thank you for your help today, I really had a hard time figuring out which country/region I should flash.

H872, no network service and service disabled after latest update

It was working fine on android 8 since it came out (4-5 months?)
There was an annoying notification since the past 2- 3 weeks for a software update, so I decided to finally do it.
No changes after doing that update, I received an another update notification of around 150 mb. ( not really sure but def. under 300mb)
After that, my mobile network service suddenly went out, mobile data is disabled and grayed out, same when I try to click on Mobile connections.
On the lock screen, it says "service disabled" and *#06# says imei null.
What happened? I know this definitely happened after the update, and my phone was bought brand new, how can i fix this?
Also, I'm located in India and use a Vodafone sim card, I tried putting other carrier sim and it's still giving the same error which worked perfectly before the update
Any help would be appreciated
I'm guessing I might have to do a factory restore, but I would like to have that as the last option

my device also shows that message "not eligible bla..bla.." I think you have to downgrade to 20d firmware. But as you can see my phone is running latest update and cellular is working fine since I believe once this phone is unlocked permanently, it will remains unlocked.

As i understand T mobile unlock sheet app, after you unlock phone, app should delete itself !! In my case this didnt happend, and the result is as I describe before ! It seems i spend 240 € for very fine but lockedphone. Next time dont buy on e- bay you idiot, i say to myself. Because two days ago i bought new Samsung A7 2018 with 64 gb for les money ! And unlocked, of course !!

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.

Question IMEI gone

Hi guys, I'm in a very big trouble, since I was trying to rollback yesterday from A13 Oxygen 13, in a converted NE2110 Chinese model flashed previously with NE2115 Rom, I was having ridiculous battery life with the rom, so I want to test the European NE2113 rom, I've download the NE2113 Rollback package and applied with the local update apk provided by Oneplus, the procedure was apparently sucessfull, but SIM isn't recognized when A12 NE2113 rom booted, I've thought its a band relates problem, so I've flashed black the NE2115, but stills the same, I've get in to the IMEI numbers, and both are NULL and Baseband is blank.
I'm in Ecuador so it's absolutely impossible for me to sent the phone to Oneplus Repair services, and even if it was possible I doubt a lot they can take the phone, because it's bootloader unlocked.
If anyone have an idea about something I can do, I'll really appreciate that, it's an expensive phone and I've put a lot of effort to buy one trought and auction sale and even played to import from United States, so if you think there any hope available please share with me, I've read the one post here with someone who still needs to repair the IMEI seeing it's impossible for now, but at least I have to try to restore the phone, I can't have a media player unusable SIM phone of almost 700 bucks.

I've tried but actually I've notice a bigger problem : battery isn't charging, I've only 30% left, tried to reflash the NE2115 with same results IMEIs are gone, phone connects trought USB cable to PC but is no way to charge it
