IMEI and Baseband problem, need help, fast - Galaxy S6 Q&A, Help & Troubleshooting

Recently, motherboard on my S6 (SM-G20F) died and I had my motherboard replaced, having made a backup, accidentally, on my old motherboard, I tried to restore all the information I had to my new motheboard.
The problem started when there was a complication durning the restore process and I was forced to flash firmware (by the way, the new motherboard is from Switzerland, the guy from which I bought the motherboard is not sure who was the phone carrier, so I was forced into flashing diffirent Swizerland firmwares) and I have lost my IMEI and baseband number.
I have already tried flashing stock firmware in order to resolve the IMEI error, Octo box and similar software are not free, so, what would You suggest ?
Thanks in advance !

Galaxy S4 i9500 Origin

In July I went to New York and bought an Galaxy S4 i9500 and messing around with the device I corrupt the EFS folder losing my IMEI.
Since it wasn't bought on my country (Brazil) I don't have any support nor warranty so I send it to a friend who owns a service box ( octopus probably) and flashing the ROM he asked me what is the country of origin of my device, since I bought in the US and this model in particular isn't supposed to be selled there I don't know wich country it came from and can't fix my device. The back label says it was made in china but i guess every other phone in the world was made there too .
(I bought it from the Samsung stand in the 5th ave Best Buy so it is original)
No problem
In phone setting option there is baseband version and build number from there you can find out where the device is from originally manufactured.
But now I think you have flashed other firmware and that original information is gone.Corruption of efs folder can be from many ways either flashing roms or wiping full internal memory by not following appropriate methods corectly.
You could have make efs backup in first place before experimenting with the phone.
But now you can try the following methods.
Try to flash latest modem to see if it help through odin.
One other method is that you can find your country of origin by your imei no which is on the box. Just call or email Samsung customer service in your country, I did in my case and they can tell you from the imei number the country of origin.

Ok Try to flash stock firmware and see if it helps and do tell me if you succeed.
You should be able to flash a stock firmware through ODIN and have the phone working again.
Then as mentioned above, before doing any work on the phone you should do a EFS backup, nandroid backup.
I remember with my previous phone (Galaxy Infuse) i was learning also how to root, tweak, modify the android and also "killed it". I was able to resurrect (in a manner of speak) the phone by loading the stock firmware the phone had when i first got it.
Good luck!
My friend said he repaired the device through the octopuss box and are sending me back. He couldnt upgrade to 4.3 because he didnt know the country of origin (like I said before). I call samsung to ask if they could say to me but here in Brazil the only company that really helps trough phone is Blizzard so I ended where I started. I found a website that using your serial number or IMEI can say where your device are from and I for my surprise it is indeed a chinese Galaxy S4. In Sammobile I found the CHN firmware that matched the time of fabrication (July) and probably its the stock firmware that I was looking for and one of the ones that I didnt tried to flash at the time.
The thing is now I'm too scared to try flashing this one to my mobile and ending ruining the device again and once more being forced to use my old ****ty iPhone. Any sugestions for me guys? (The device didnt arrive yet... i knew the serial and IMEI 'cause i noted down)
You don't have to flash firmware for country of origin. I'm in New Zealand and flash firmware from all over the world, the latest was UK firmware, with a modem extracted from Austrian firmware.
Just go to sammobile and make sure it's for i9500 and you'll be fine mate

What is the serial number of your phone? You can find it by beneath the battery or in settings, about device, status.

It's below the battery, next to the IMEI. It is a combination of letters and numbers and looks like this "S/N: XXXXXXXXXXX" (X= Letter/number)

[Q] IMEI corrrupted

Bought a new S6 from Ebay that had been opened up to all networks. Discovered it was rooted which I didn't want so I flashed it with a stock Vodafone ROM. The phone worked fine for about 10 days then all of a sudden I got the message 'not registered on network' when I try to make call. It turns out that the IMEI number has changed. Does anyone know whether this type of problem can be sorted out?
Flash back to stock via odin.

IMEI Corrupted
I'm going to use a Vodafone ROM as this phone was originally on Vodafone before the seller had it opened up to all networks. THE ROM is G920FXXU1AOCZ_G920FVFG1AOC4_G920FXXU1AOCW_HOME.tar.md5. Does this sound like the right one? Sorry for all the questions - I'm new to this. The other thing worth mentioning is the IMEI at the moment is 350000000000006. Where could this have come from? Any ideas? It's weird because the original IMEI was in tact for about 10 days before it changed to the one above. Any help at all would be appreciated

Corrupt imei is known issue when flashing and rooted. That's why firdt thing you do when rooting, is you backup your stock rom together with efs folder. Idk which is your stock rom, you have to do some research, download that rom and use odin to go back to stock. You will lose everything you got on the phone btw so save any pictures or music.

Thanks for that. The problem I have is that there's no backup of the EFS folder or the stock ROM. Without these, is there any way of sorting this out or is the phone dead? Cheers
hi
i have same problem did you fix that if yes please help me
Bring S6 back to Samsung for repair
My guess is the phone you bought was stolen and after 10 days it got blacklisted.
Or the seller claimed he lost his phone to insurance company, sold it you, got a new one on insurance, and then after the 10 days the "lost" phone (your phone) got blacklisted.

I have the exact same problem, bro. All of the sudden my IMEI changed to 350000000000006 and I'm not able to register on my network. Did you manage to fix this? Please, let me know.
The same story, any help?
How I can fix this? Please help
Get Chimera tool and you should be able to fix it no problem
Did you manage to fix?
My baseband shows as attached after installing vador rom so I'm confused
If you didn't formatted/wipe the efs/nvbackup, there's a chance you can retrieve your imei.
But if it doesn't, the only way is to bring it up to Samsung or a good phone technicians to repair or get you a new branded IMEI for your phone. Mine was fixed by a technician using Octopus box tool.

Fix a soft bricked g930f with backup from a good g930f?

I purchased a g930f off of Swappa and somehow soft bricked it to the point where it lost its imei and even if I get it to boot, it won't access my provider (ATT). I bought another one (yeah) and it appears to have exactly the same firmware that the bricked one did when I got it. I wonder if by making a nandroid backup of the new phone, I can get the old one working again, and somehow get the original imei reinstated on the bricked phone. I do NOT want to fake an imei, or do any other illegal thing, just get the first phone working again and hopefully reinstate its imei and serial number. Anyone have thoughts on this?

Try using Odin and download mode to get back to stock. That should bring back your imei. I think because you restored a backup from another phone, it tried to write the new imei on the old phone causing an error. Let me know how it goes.

I never did get back about your reply, but you were on track with your suggestion. I ended up finding the factory binary and flashing that, which got me back my IMEI and able to boot again, and then flashed the proper firmware. All is well since then.

restoring imei

i had corrupted efs partition i took it to a local repair shop they fixed it. it was rooted and downgraded to 5.1.1 and the imei was changed,..right after that i backed up my efs,flashed official 6.0.1using odin and then i flashed xtrestolite rom.but in xtresolite rom it does not shows imei while i press *#06# but it shows imei in about device/status/imei information and there is no issues like emergency call only.i tried flashing my backed up efs partition but the result was same. now the question is it fixable ? and can i restore my original imei as i am planing to sell the device.
It's just a ROM problem. If you want to sell the device, just install stock ROM.
I dunno, I have XtreStoLite and *#06# shows IMEI & S/N. Don't think it's a ROM problem. Did you ask guys at repair shop about it?

[Fixed] My SM-G955U Has No IMEI or Baseband

EDIT:
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition.
So, here is a bit of a story I will try to keep short.
I went to Vietnam and bought a S8+ from there.
It was a US S8+ from Sprint.
I used it fine there but when I came back to states I tried to put my Verizon sim in and it doesn't work.
I don't get any signal. But I am able to see Baseband and IMEI.
So, I tried to use Odin and flash one of the SM-G955U1 Firmware.
Now, my phone is weird and out with no Baseband or IMEI.
So I try to flash back to firmware it was on.
Same thing.
Any ideas why my S8+ is like this?

Can you get into recovery/download mode now? What was the last known version of software you know that was on your phone?
If you can get into recovery, what info are in those details?

What happens if you restore from the OEM function?
Try downloading custom recovery and flashing a custom rom. You will lose samsung pay but you might have a working phone it's a chance I would take if it was me. Your baseband is messed up try just flashing your carrier baseband . These are just ideas good luck

If flashing a custom ROM will fix your phone then so will downloading latest official Samsung ROM and flashing via latest Odin .
The second option above would be the best to try unless you're happy to have a custom rom and lose Samsung pay and anything that relies on Knox being functional

Update on the post, I sent it into Samsung. I should hear word soon if they can fix it and how much if anything.
Jtag dead phone to life and rewrite IMEI
First of all my phone is the s8+ G955fd, but I am sure that the people that helped me can help most Samsung owners with bricked phones.
My phone ended up being stuck on the first boot screen, I couldn't get into recovery or download mode. I installed TWRP and after that I lost my IMEI numbers( dual sim), so I tried to reflash stock and thats when i became bricked. I searched someone to help and found reference to the Fonefunshop in England. I sent it there and they said that the eMMC chip was bad. I searched for someone who could write to it or put a new one on the motherboard . I found A2Z cellular in Ottawa Canada. They used jtag to restore it to stock and they told me that the Fonefunshop had not opened the phone which is necessary to use jtag as they claimed, so avoid them.
The phone was now back doing everything it should except the IMEI's were null like before. I gave them the original IMEI's and the phone is working like new.
If your Samsung is bricked these guys can probably fix it and it won't cost much to find out.
the SM-G955U has a locked bootloader, so people should not be telling you to flash a custom recovery or custom ROMs. there is only one way to get root on this phone, through the samfail exploit, and safestrap is the only working recovery. I don't believe it supports CDMA networks but I'm not 100% sure on that. I have this device and I'm only aware of GSM carriers using it.
Just an update on this issue. I still don't have a working Baseband or IMEI. Any clues?
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition via ADB.

Be very careful with doing that. It can cause the EFS (the partition that controls IMEI, Mac and a few other things) to be completely corrupted. Which will cause the device to be useless without fixing it.
Now a little heads up. As messing with the IMEI is illegal in many countries (the US being one of them) There are only 2 ways to fix an IMEI issue allowed on XDA.
1. Restore the backed up EFS partition
2. Return it to the OEM to be repaired.
What did you do after you deleted EFS? I can delete in Combination but I dont get the IMEI number back.
Please I need all XDA members assist ,because of I mistake delete EFS with combination file on my G955U VZW , I have null imei number, then I repair it by flash qcn with z3x Samsung tool , but still I have IMEI number but emergency call only is still display without service ,
