Seems my IMEI changed while flashing. Can I restore my old IMEI somehow?

Hey all. Got a brand new Note 3 about a week and a half ago from a T-Mobile store and it stopped connecting to network last week. I've been having a back and forth with T-Mobile and I was told that my IMEI was blocked and I was told to exchange the device. I found out today that the IMEI on the phone does not match the IMEI on the box. Seems this IMEI was blocked for non payment. Can the IMEI change from flashing roms? It's it possible to restore it somehow?
Any help appreciated. Thanks.

Ok short answer, NO.
It is not possible for a rom flash to change an imei. The rom is on a completely different partition. There is a lot more work involved in changing that and a simple flash would never be able to accomplish it.
if your imei on the phone doesnt match what is on the back of the phone then you need to take it back.

Where did you buy it from?

I highly recommend you do as the carrier suggests. Take the time to go visit them and do things "above board".

A5 2017 imei

Hello, I bought a used a5 2017 phone from ebay and when I received it, my sim not worked, then my brother's sim either. I think the imei is being blacklisted. Is there any way to change it, or how?

You could try reflashing stock modem. Also Does Samsung pay open?

Someone know how?? I have never used Odin.
Here is a tutorial on the web for an older version: https://skipsoft.net/flashing-a-single-partition-i-e-system/

If the baseband version/ids/content in *#0011# isn't there, try
restarting the device?
changing firmware, preferably with a newer modem?
wiping data?
For installing firmware, there's odin. Use odin, the stock rom (official firmware), and samsung drivers, Insert the usb cable, switch off the device, hold power+volumedown+home(the button on the middle), grant its permission, select the stock rom in odin, start. New firmware might require odin 3.13.1. The error "failed: device _ binary _" means that the firmware is old, somewhere in the middle of the firmware version code is for example U5 or S5, if U6 or S6 is already on the device it won't install u5/s5.
To check if the device is blacklisted, the code is *#9900# > run cp based log > copy to sdcard. Select nothing else. It is available in the folder /sdcard/log/err/ , sdcard meaning internal storage or device storage or internal memory. Open LitmusLog....txt and scroll down, look for the part that says reject info list, look for Cause:6 (basically this device can't be used); Cause:3 (basically this device can't be used with this sim). It is also available in /sdcard/log/err/ss_log/*/cp_members.txt , but the reject cause is in hexadecimal, and resets after a reboot, compared to the other file that keeps reject causes until it's replaced or cleared in another menu. For more info contact your mobile network operator.

Sadly this not helped, the imei is blacklisted, and modem update not fixed it for me. :/ I contacted the network operator and because I'm not in contact with the person who sold me the phone, they can't tell me anything, because I don't have the rights. So I think the only way is the imei changing method, but I don't know if it's even possible or how.
Sorry if my English is bad, and thank you.

I did a bit of research....
- it is illegal to change imei- if hat means anything to you, lol
- it is against Ebay's policy to sell phones with bad imei
- there is an xposed module to change imei but you would trip knox

I think in my country it's not illegal, but not quite sure.. And i didn't know this, the guy wrote it down in the ebay ad even, so it went through.
Thank you, I will look into it, but I think I will sell the phone as a 'working display part'.. Motherboards are not cheap.

It's perfectly normal except you can't use a sim card? Or is there more things wrong when imei is blocked?

It's perfectly normal, everything works, except if I insert a sim, it will show a notification: ' can't connect to network '

Imei is locked to the device as far as I know. This is why a device can be blocked after being reported as stolen. If it is imei blocked then you should get a refund or make sure Ebay is involved if the seller refuses to.

Hi,
I am from Oman. I bought Samsung S20 T-Mobile/Unlocked version G981U from ebay which was confirmed by seller that it will work overseas and got delivered via shopandship by aramex.
Later found that it is T-mobile locked and has bad ESN. So my friend suggested to use unlock service from ebay to unlock so that I can use worldwide.
I bought unlock service, seller told to pay direct to PayPal and connected to my PC using team viewer. He worked for more than 3 hours and he couldn't do it. He refunded. Then I found IMEI is empty! BASEBAND UNKNOWN!.
He said it is not his mistake. IMEI is bad, so unlock was not successful.
Initially I sent him IMEI. But still he doesn't accept.
Can someone please help me to recover imei?

Why not file a case that you were sold something that wasn't described properly?

@vickytheboss Vicky, just for information. I've moved your post from the OnePlus 6T device forum to here, the Samsung Galaxy S20 Q&A as your issue and question was not really related to OnePlus. I hope you get support and find a solution here.
Stay safe and stay healthy.

Emergency calls only. HELP!

Hello
I bought a used s9 a few months back. It had dual sim. In "about phone" it said G960F and was on android 9. A few days ago, I wanted to flash android 10 so I downloaded firmware for G960F, booted my phone in download mode and SURPRISE. The whole thing was in Korean and of course it was a G960N model. So I downloaded firmware for G960N this time and flashed it. Everything went perfect but when the phone booted up, It had no sim service.
I've tried everything I've found on the forums so far related to emergency calls only or no sim service.
Any kind of help would be appreciated. I have no sim service for 5 days now.
Things I've tried so far:
Flashing my phone again with android 9 stock firmware, which I can't do anymore as I've updated the bootloader lol.
Flashing custom roms
Changing csc from SKC to KOO
Flashing OXM CSC as I live in Pakistan
Flashing different modems and basebands
Nothing worked

Try flashing back a G960F android 10 firmware.

How can I do that? I always get a PIT error.

What if you don't flash the pit file?

Done all of that. No luck

OK, let's go back to beginning: you've bought the used phone. 960F never was (as factory leaving) dual sim phone.
so, let's start from the beginning:
contact the seller and ask what the hell have you bought (if it was any variant of the S9 at all.. somehow I doubt it).
2nd: write down the IMEI and serial number, and check with Samsung if this configuration ever existed (if not, what I suppose, the IMEI/sn info about the REAL model can give you a hint what have you bought).
Having the above info in hands, find the "service firmware", 5 files ROM for your device and try to flash it.
If it will not work still, I'm afraid you have two options:
1. check IMEI against stolen devices with your carrier.
2. Go to Samsung service asking for help.

Well mostly it isn't a fake mediatek phone as it will not even have a download mode.
Probably he bought a shi**ily refurbished phone with it's internals mixed from multiple versions of the s9, in the best case.(a Frankenstein variant of the S9)

I'm going to solve this mystery for both of you. The phone he bought is indeed an S9. Here in Pakistan, 'software' guys in shops can convert these to dual sim models with some z3x and Chimera f*kery.
As for why his phone isn't working - it is because the phone had a tampered IMEI to bypass local custom charges levied on all imported phones (insane charges, doubles the price of these kinda phones). Once he flashed a new image on his phone, his IMEI status would have become NG instead of OK, which prevents the phone from accessing any networks.
Solution is to visit the same 'software' guys, ask them to 'patch' the phone. It is a 5 minute process, requires root (which these phones already have).

well, you can temporarily use someone's qcn to check how much tax you'll have to pay for "a refurbished phone" once you get back the original imei.
Edit: This'll help
