Long story short, my imei is not the current one under the battery and i want to get it back. Before i thought my phone wasnt unlocked and that was the problem but its not. The phone is unlocked and i even have the codes, i just want to use my own IMEI. I currently can not connect to any networks with the captivate.
So far i have tried using the .bak file in /efs with no success (different imei).
I have tried several posts on xda but all seem to unlock and not give you your proper imei back.
Any advice or information would be greatly appreciated.

How did u manage to mess it up, may I ask. This way atleast u could warn the rest of the community not to mess ours up.
Its quite simple really, dont back up your /efs folder and keep messing around with roms.
I don't think anyone has solved this. Everything around the nv_data.bin file relates to unlocking and it says you must have a good IMEI number to start with. There was some 3rd party software that can fix IMEI numbers - but it required a separate breakout box. I forget the name, but many downloaded the software only to discover they needed to buy the box to get it to work.
One of mine managed to wind up with the generic imei but I have yet to see any ill effects from it.
I am sorry to hear about this, and even sorrier to have to say this, but xda does not allow posting of instruction on how one can change the imei.
Sent from my SAMSUNG-SGH-I897 using XDA App
Ok if we cant talk about this thats fine. Right now i cant connect to any networks. If someone would be willing to upload their /efs for me so i can try it out. Would that work?
Im in Australia so anything apart from that should work right??
did you ever got to restore your original imei?
Check here for a how to restore your IMEI.

You need root privileges to read and write to the efs folder. You can try flashing the Odin files, but it will wipe your phone so back everything up.

I'm not going to do that, and I doubt most other people would be willing to give you their efs folder. I understand the predicament you're in and I'm sure you are well-intentioned, but this would give your phone the same IMEI as my phone. First off it is illegal to have two phones with the same IMEI, second you could potentially report the IMEI stolen and lock my phone or worse. While I don't think you'd be malicious it, I'm just not comfortable giving it to you.
This would be very similar to somebody giving you a copy of their license plate from their car because yours fell off. It's just bad idea.
Since Odin won't work (it should), I suggest calling Samsung support and tell them you received an OTA update via AT&T and your phone doesn't work. Unfortunately you're going to have to lie and tell them that you were in the United States on AT&T's network, but hopefully you can send it in for a warranty repair.
In the future (I'm assuming you bought the phone for full price and it isn't subsidized by your carrier), always buy the international version of a phone with an unlocked bootloader. If you're paying full price for a phone there is no reason not to buy a bootloader unlocked phone because you would have a lot more options if you run into problems. Sorry I can't help, but hopefully you are able to resolve your proble.

I understand the predicament you're in and I understand that you have software that will change the IMEI to your value, but even if you are able to do that, how are you going to get it on the phone? As I said before you need root privileges to read or write to the efs folder. So even if you are able to make the changes with the software you found you have no way of loading it to the phone so you're still in the same situation you are now, you just have my efs folder.
There should be a local Samsung representative in your country, try calling them, maybe you won't have to ship it to the US.

yes youre right i need root privileges to do it in the phone however i have learn how to créate a image file to flash it into the phone with ODIN i have found that this has been done in some older models like in the Galaxy note 2 or Galaxy s3 you can find that info just for you to make sure that im not lying to you. thats why im insisting on this cause i have found similar problems with those phones and the way to fix this is the one im trying to do. i understand that this may sound suspicious but im not trying to do anything wrong with your phone im just trying to fix mine i understand that is not your problem but maybe i can find a solution for other guys who will have this kind of problem.
i know is not your problem but please sir let me try and probably i can do something good and then i can share what i learn here
and here i have Samsung Guatemala yes youre right and i have took my phone to them and they were not able to fix it. because its not from the country and they cant do anything on this case so im stucked to this

So you're going to run into another problem then, the bootloader on this phone is locked so you will not be able to flash anything that isn't signed by Samsung. If we were able to flash things to the phone then we would be able to root and install custom recovery. You're pretty much screwed, you still don't have a way to get the efs on to your phone.
The ML2 Odin files should fix the issue you're having, but as you mentioned before it isn't. Did you flash the ML2 bootloaders? If you didn't then you can always downgrade to MF1 or MI2 and root the phone. I'm sorry I can't help you, but you really don't have any way of getting the modifying the efs folder on your phone without root.
Hi guys, I'm trying to unlock my S3 Mini and I'm having no luck so far. I've managed to root the phone using the iRoot (former Vroot) program and it worked nicely. At least it seems it did, now it does ask me to give su eprmissions to allpications and busybox is installed.
As for the unlocking itself, I tried several methods. Firstly, there was some service menu, accessible by a long string of numbers on the dialer, then going to network lock menu and setting something there, but the menu isn't there. Or better said, when I come to the Network Lock, it says only Not Active and no further options available. Then I tried the GalaxSim Unlock just to see, but as it said in the notes, this version of phone is not supported and so it didn't work. Same with another app, Galaxy S Unlock, or something like that. That one needs busybox, so I installed the 1.22 I think, but it says that there is a problem with busybox or something. It does say in the notes, that recommended is 1.17 busybox, so I keep that as a backup hope but it seems again, that the phone is not supported...
So basically, I have a rooted S3 Mini, that is still locked to T-mobile. I'm not sure, whether the country of origin matters here, but I think it was purchased in Austria (I am not the first owner) and need to unlock it for slovak O2. So far I am actually very happy with it's stock ROM, so I'm not planning to flash it completely, just sim unlock. So if anyone has any idea, what I can do to avoid going to a phone service and have it done for money, I'd appreciate it.
GT-I8910
stock Android 4.1.2
I8910XXAME1
Seriously noone has any idea how to unlock one of these machines? I've seen so many people talking about unlocking this and none of the methods mentioned worked. So please, pretty please, if you have any info on this, share it...

Hello XDAs,
After reading that Forum with much enthusiasm for a few...well...years, i got my first question.
I hope you can help me with a big problem on my g800f: I can´t register in network.
When I search for network it pops up a few results, but if choose one to register, it says "Can´t register. Try again later."
I did a few hours of research and found out it might have something to do with my IMEI (Note: till that day i did nothing to my phone, except cf-autoroot. But never faced any problems!).
So I checked my IMEI and it wasnt the original, it was changed to 350695200123951. So I googled a bit and realised it might have something to do with the efs-partition. Googled for solutions.
Found out it might help to flash a Stock-Rom, one with three parts, via odin so i did it. Everything worked fine, but my IMEI still was the different one.
I was a bit irritated so i searched for that IMEI. And there are a few threads (some in russian and arabian), also owners of a g800f, which also reported this problem: They did nothing, but sudddenly the IMEI changed to this number. One author tells he received a myserious call from the ukraine after this happened. He didnt answer it. I am quite sure i also received that call- I didnt answer it either.
So i googled even mre: "How to restore a damaged efs-partition, without backup?" I came to one very outdated guide which wanted me to delete the efs (after saving it on externalSD) and do a few mysetrious actions...
Well, i just realised i cant fully delete the efs, its not possible and i also cant apply my backup from external sd. Anyone knowing a solution for this?
But, the most important, how can i bring my g800f back into mobile network?
Or just: How can i get away from that cursed IMEI?
Any Ideas?
P.S. If you got any questions regarding technical details of my phone(CSC, AP, Kernel, Modems), just ask. I´ll answer.
P.P.S I´m excusing for that horrible english. I googled the entire night and i´m german.

I´ve just seen this problem being reported i a different thread. Guess the problem will be discussed there?
Hi All,
Did any one actually get a fix for this issue as I have exactly the same problem, my SM-G800F IMEI now also shows as - IMEI 350695200123951-01 which is for a blacklisted NOKIA 6310. If anyone can supply an absolute beginners guide for me as to how I can get my original Imei back that would be fantastic.
I am just a user of an android phone and have zilch experience of tinkering with them.
I have seen reference to things like Odin and flashing firmware and am quite happy to give it a go myself and learn
I will post this on a few other threads that list the same issue as I am desperate to get this fixed now as is a waste of a perfectly good phone !!
Cheers.
SM-G800F, can't register in network
Hello,
I have exactly the same problem. Since some month I got the message "can´t register in network". After checking all, I found that my SM-G800F IMEI has changed to a NOKIA 6300 IMEI.
If anyone knows a fix for this issue (set back to the orignal IMEI) , it would be great. All apps which I could find didn't work (XPOSED IMEI Changer Pro , Mobile Uncle Tools App, MTK Technikmodus... ), are not supporting S5mini.
I don't have a backup of the original system EFS file.
Would be great when one could help.
Regards
Chris
@S5miniChris somewhere in XDA I read that restoring the original stock (multiple part) firmware might or did help.
Gotta do it in Odin (recommended to use an older version like 3.09).

Thanks for your reply.
I have installed the original stock firmware. But it did not change the IMEI. Available for my model is only the single file " G800FXXU1CRG3_G800FDBT1CRE1_G800FXXU1CRG3_HOME.tar.md5"
Multible file firmware I couldn't find.
A manual modification of the IMEI should be possible with " Best smart Tolls " e.g. : BSTPRO 4.03 . But for the software a dongle is requiered. To purchase this is for one time use too expensive for me

Where from did you get the stock?
Samfirm_reborn tool already tried?
https://github.com/ivanmeler/SamFirm_Reborn/releases
Checking "binary nature" or "factory mode" downloads a multiple part rom.
Edit:
Checked tool and it's working.

I flashed now also with " binary nature " firmware downloaded with SamFim. The IMEI is still the same, it hasn't changed to the orginal IMEI.
I really can't believe that a firmware update will flash the E2PROM where the IMEI is stored. Therfor the orginal IMEI must be stocked some where
in the phone and by flashing transfered to the E2PROM.

You have an n900a? If yes, where did you get the 4.4 and 5.0 stock ROMs? They were never released by AT&T.

I used custom roms off XDA hoping it would somehow recover missing IMEI
Is the phone an n900a?
Yes SM-n900a
Made in China
If the stock roms don't restore imei and baseband, the efs folder may be damaged. A completely stock flash may be done via JTAG.

Long time since I've heard that.
Wish there was something I could do on my own. I was hoping maybe just a modem flash.
I'll standby for a few more days then if nothing I'll start looking into what they could do.
Where did you get the stock 4.4 and 5.0 ROMs?
Here on XDA

I believe they were both from the unified threads.
you can find 4.4.2 stock on here
then 4.4.4 and 5.0 were based on official release.
Update
Still have no clue whats wrong
Either something is really wrong on the software side of the phone beyond Odin (maybe JTAG)
OR
The Sim card slot on the phone is damaged.
The phone was given to me because the old owner was never ever to get it working and gave up.
I have the IMEI on a sticker located on the back.
(Yes I know discussion about changing IMEI etc is banned that's not what I'm here for)
My main question is what can be done if I don't have an EFS back up? Is the phone just a softbrick/parts
If so plan forward is just to use as a car dock lol.
I am in the same boat man. I do not know what to do, to get my imei back and baseband. i posted a thread as well similar to yours hopefully one of us gets a success story!!!!!!

The first step would be to try to find the proper basebands. Dont know where any of the firms are located. Im trying to dig them all up. And reupload them but may take some days. I am hoping to temperarelly revive this device as i have gotton one myself.
Best of luck

My goal as of now is to find a t mobile 1 with a broken screen and switch boards. Done with the boot loader being locked.
I was instructed to do 1 of 2 things... 1st like you said buy a busted up phone with a good logic board and swap. OR 2- buy that same junk Note3 and copy the efs files and install them into your phone and switch the imei to yours. etc... I gave up on trying to revive mine so I no longer can tell you if it works or not but it seems to be the best 2 options friend... good luck let me know if you get it with one of the options....
