[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.

but i checked IMEI is clean

Oh right, that's weird then! I guess efs partition could have just randomly corrupted.

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.

Network not available at recently 4.4.2 flashed N8000

Hi guys. I'm posting here in a desperate attempt to solve my problem.
A year ago I purchased an used N8000 with Omega 4.1.2 ROM installed, and worked very good. But a couple of days ago, I flashed my tablet to get the 4.4.2 update, because I need some apps not compatible on old versions.
Everything is ok except for the fact that my sim card is not recognized anymore, if I select the operator manually, I get a "network not available" error.
I made a lot of research, with no results so far to fix the problem. The only thing I learned is that I think it has something to do with the baseband version. Currently I have the N8000XXUDND2 version, the IMEI is ok.
I live in Paraguay, the 3G band of my operator is on 850MHz.
If there's no solution, can I just downgrade to the omega rom by flashing as usual? Or the process is different?
Thanks in advance

Tried flashing the modem I had before, still no signal. I think I screwed my tablet.

when u flash a rom then downgrade it the phone's imei code gets changed which causes "no network" error .
I'm trying to figure out restoration process of original imei code for my device too.

I don't even know how can I check the original imei of my device, since I forgot to write it down. On phones they are usually printed behind the battery, but this doesn't have a detachable battery.

If your IMEI is wrong then restore your backed up EFS folder .

It's written at the bottom back of the tab & on the box seal as well. Or dial *#06#. I tired hard reset & stock rom still imei error

I checked and indeed there's the original imei written at the back of the tab, and it's not the same number as of dialing *#06#. Don't know how to restore though since I didn't back up any efs folder.

You can do a search on XDA there are a number of posts regarding users that failed to backup EFS and null IMEI .

I have the same error, after root, imei and baseband are gone.
don't have efs backup

Samsung Galaxy S7 SM-G930F - No Network (SIM - CARD)

Hello Guys, this forum is my last hope. I have a problem with my S7 (DBT Germany), I think after flashing an older stock rom and going back to newest, something happened that my phone doesn't detect any sim cards anymore. If I type *#06# , it only shows the SN Number, no IMEI. WIFI still works without problem, but I can not use my sim card anymore, so it's pretty useless now :crying:
The sim card works on another devices, so it's for sure a problem with my s7, I might have messed up something. What do you think is here the problem and how can I solve it? Any help is much appreciated, I really hope to fix this because my phone is only 2 weeks old.
I currently have the latest Firmware for DBT from updato, (December 14, 2017 for Android 7.0)
IMEI = unknown
SIM Card status: Not avaliable

Have you tried a stock ROM from sammobile.com? Updato and sammobile.com should have the same ROM but maybe there is a difference between the 2?
Did you confirm that the phone is running the latest modem?

I did not try sammobile because updato and sammobile were the same firmware. Sammobile does have a newer firmware from 28/01 but it says I need to join in order to download.
Is there a way I can fix a damaged/corrupted EFS ? My phone is pretty useless now without sim card detection

Sorry, I know of no way to fix imei issue if a combination of Odin and a stock ROM does not work. You may have to take it to a cell repair shop that can force flash the ROM and EFS using hardware like an octopus box: https://octopusbox.com/eng/features/models

You would need a way to recreate the contents of the folder. Unfortunately, I'm not sure how to create the contents.

Hey, I have finally found the solution and my sim card is working again :victory:
It really was just that the firmware was 1 version older.. I downloaded the latest DBT Firmware from samsung-updates (Build Date: 15/01/2018)
Put Bootloader to BL , AP to AP , CP to CP , CSC (not Home_CSC!) to CSC , flashed it and finally my IMEI etc. is back.
Thank you for taking your time trying to help me

Congratulations on your success

[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?

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 ,

Samsung xcover 4s (SM-G398FN) IMEI wiped

So i got this xcover 4s with a imei issue, the imei just shows 0's .
I tried looking for a root for android 9.0 i could not find any to modify the imei nor could i find a combination file to try it with factory ime.
Is there someone who could help me with this it would be much appreciated!

IMEI discussions other than restoring from a IMEI backup are not allowed.
Other than flashing your original stock firmware to see if it "by chance" restores your IMEI, we can't help you because you obviously don't have a IMEI to use for the restore process.
Good luck.

I got the IMEI it's written on the back of the phone.
But besides that i'm just looking for a root option i've tried patching the boot.img with magisk but when i try to flash it with odin it just freezes.
also there is no twrp available for my device...
do you have any tips for me on rooting the phone?
