Missing IMEI and EFS files. Can you help?

Hello everybody!
I read for a several days about my problem. My IMEI is missing (*#06# shows only 000000000-oes). I never made a backup of the /efs folder, and there is NO any original bin or​ bak files.
I tried several methods for repairing the IMEI, but without success.
I tried to copy other nv_data.bin file into the /efs folder, but after reboot (or removing the battery) the file is missing.
My question is - Is it possible to get needed files form other owner of such phone? Have in mind - I'don't know the original IMEI of the phone too. This phone was a gift to me from my employer and I never get a original box (where the IMEI should be written).
So the situation is:
1. I have not original IMEI
2. I have not bin files or bak files in /efs folder
3. The phone is rooted, and etc.
Any suggestions?

Try flashing the stock rom using odin. I got this problem once with my Galaxy S and that was the only solution that worked.

I already did it ( without result. In fact flashing with stock EU rom take my phone to cyclic reboot. The Android OS can't load at full - loading styas at white characters (Samsung Galaxy W) and after 1-2 minutes it restarts again.
I tried several flashes with ODIN, finally I used ASIAN version of the stock ROM and the phone now is running. Thanks God!
If there is no other suggestions I can try again to flash stock rom. Please can you provide me some links? I think I used links to the stock rom, given in that forum but... if you tried and tested some, I'll be very appreciated.

The IMEI is also written on the sticker on the mainboard under the battery. Not sure it will help you that much though, if you also lost the other /efs files. Good luck though.

***WARNING*** PLEASE BACKUP your EFS!!

***WARNING TO ALL***​FLASHING ANY FIRMWARE CAN POTENTIALLY BRICK YOUR DEVICE ​
With that said, PLEASE use some precautionary measures to keep your device alive!​
There are many threads out there about making a backup copy of the "/efs" folder. that folder contains all of your IMEI information that is NOT replaceable! There are several cases all over the web, about people who have lost that information causing them not to have service, leaving them with "generic" IMEI's and some with all "0's"
I am posting this to help prevent thoes who are unaware of the consequences that happen when the EFS information is lost!
Here I will post a few guides and informational threads here in XDA to help with this.
EFS Tool for Windows
Guide for the Galaxy S II
A Story From the Vibrant
From the Galaxy Note​
I would also emphasize on making a nandroid backup of your complete system in recovery before starting to venture off onto any custom rom!
Here the folks at XDA have built a great community with a outstanding reputation to help one another advancing to the next level, also unlocking the extreme potential of our devices.
Be sure to "hit" the thanks button and when possible post a personal "Thanks" to the great devs and contributers we have here in XDA!
Feel free to add to this thread, any useful tips and such...
Thanks and God bless.

I have not yet confirmed this, but here are three links to what may be a way for those who have lost their EFS to repair it!
there are other guides on how to recreate the efs folder but these tools may enable us to insert the correct information!

I just copy and paste in my pc the EFS folder, thats enough? and how you can identify if there is a problem in the EFS?

That should be enough, but I would make backups in at least to other ways just to be safe, it's better to be safe than sorry. a single file can get corrupt without your knowledge! find a on-line file host like Google drive and that way if your pc was ever to go down it will always be there. Just don't loose your password!!!
to know that there is a problem, check the about phone section in status, the device will show your phone info, look for the IMEI! if it reads all 0's or a generic number starting with "04" and ending like "40000" you have problems! that is a unique serial number that identifies your individual phone!
I'm also not sure that if you were to use it to call an emergency hot line like "911" they would be able to locate you in time! that may not be true tho!

the serial number so far is not a problem! it's the IMEI that you need to worry about! some refurbished phones and others that have flashed a custom rom will display an all "0's" serial no.
this is simply a helpful warning to make a backup before doing any modding! and finding ways for others to repair what is lost! if your phone is ok, just make a backup and your good!
One day we will figure out how to completely restore a lost efs and edit what is needed to get back to the norm!

Thanks to Pierreone, I added a link to a thread that looks promising and has success reports!!

Whew, I got lucky. I don't have an EFS backup and have flashed several custom ROMs, but I referenced About Phone against the label under the battery and my IMEI is still intact!
Could someone post what the Generic IMEI is so people can know whether their device is intact?
This is a a bigger problem than it sounds, because in some countries, changing the IMEI may be crime and land you jail time! If the IMEI under About Phone doesn't match the under-battery label, you could be in deep ****.

About the efs folder ?
First of all Thank You for the heads up... I'm finding out a lot about backing up the efs folder but not a lot of detail about what exactly is contained in it other than imei and serial... probably because it shouldn't be fooled with but I like to know how things work in detail... is there any detailed post or site where I can get a complete explanation about it ? Complete file list/tree? What else does it control ? Can it be edited ?

EFS Tool for Windows

This utility works fine. Just wanted to mention 2 things that you need to set before running this successfully:
Settings -> developer options -> android debugging enabled
Settings ->Developer options-> Root access -> set to 'apps and adb'

I followed the guide from the Galaxy S2 forum, and after the first command:
busybox cp -a /efs /sdcard/efs/
Every line says "can't preserve ownership of..." and "operation not permitted"
Am I doing this right?
I did get an efs folder on my internal storage which is about 5mb in size after that command anyway
The rest of the guide, all of the other commands went through ok.

Holy crap, I wish I had listened to this warning! After flashing a great new rom and getting it 98% set up the way I like it I was deleting some junk apps the marketplace had auto installed, one of them (for wi-fi hotspots I think) was to blame and must have toasted my IMEI.
I thought, oh I'll just restore my CWM backup from an older setup - md5 error can't restore. DOH! After spending most of two days hunting for solutions (none of them linked in this thread worked, except I did get to where I could place calls with a generic IMEI but no data or text). I finally was able to recalculate the md5 manually and restore my old backup, which then got stuck at boot logo, then I flashed a new ROM and the IMEI still isn't back! After much reading I have come to understand NANDROID BACKUPS DO NOT TOUCH THE EFS. That is one thing that that I didn't understand, and the reason I thought I was safe. Please update the OP to state that so more people like me will listen to your advice.
Backup your EFS! Thanks for the warning

Victory!!!! :victory:
I was so close to just paying at http://sam.123unlock.nl/ and using their service to re-write my IMEI (because they show an unlock video using our phone and their software), but I kept digging in XDA and trying everything I could find. I tried the SIII IMEI editor, NV reader-writer, manually restoring the .nv_data.bin, mobiletech videos backup script...blah blah blah. I tried restoring CWM backups, flashing back to stock everything, using kies, I was trying everything! During all this I at times had no IMEI, all 000s, and a generic #, each of which provided different levels of services. I considered keeping the generic IMEI which AT&T didn't seem to mind but then I finally stumbled on a solution.
In reading the http://forum.xda-developers.com/showthread.php?t=859914 post which is linked to in the "A Story From the Vibrant" in the OP I tried the abd EFS tar command and executed it on another Captivate Glide I have that had some water damage but is mostly still functional thinking I could overwrite the entire good EFS of that phone to my good phone with the hosed IMEI. I used AROMA http://forum.xda-developers.com/showthread.php?t=1646108 and deleted the EFS from CWM (I felt like adb and terminal weren't effective since the OS was still awake) and then restored from my working EFS tar, then wrote on top of that the first backup of the hosed EFS I had from before I started messing with it (thinking I'd try that before trying just the other phone's E)FS.
When I rebooted I had the correct serial and IMEI back for the phone! It is now working 100%

I flash alot from to rom, if i use the aroma file manager n save the entire efs folder on my external drive ,if i were to ever run into problems can i go bak to aroma file manager n just restore the efs folder and make everythinfunction again ?

Some guys say yes, others say use the tar command to preserve file permissions. I backed it up both ways. When I used aroma I deleted the files and replaced them rather than over-writing the corrupted ones and it worked fine for me.

So I just got my captivate glide bought it used and I followed thegreatones instructions to get CM 10.1 using the factory image to get it to 4.X then flashing the rom.. and after i flashed CM 10.1 my imei was gone. SIGH. I don't have a backup, which of the paid services works the best? who has tried them?

I managed to make EFS Pro work but the glide is not listed and I don't see any partition to backup. Am I missing something?

I haven't tried any but I would first give AT&T a call. They can probably assist you. And I believe there's a 14 day return date, I believe AT&T only checks the physical aspects of the phone.

After installation i found that i kept on getting Not registered on network ERROR. I checked the imei and still corresponded with the one on the back of the phone.

There's a lot of contributing factors that might cause this eg. Sim Card IC, ROM compatibility, Modem Issue and so on.
Try go to setting / more settings / mobile networks / networks mode and set to GSM only. Wait for two mins or restart the phone.

This looks like modem problem. Try to flash another modem, better via odin from pc

Ok what have you lost?
If you have the correct imei then flash this tool and it will recover your network.
http://forum.xda-developers.com/showthread.php?p=32338426
If your imei isn't correct either 0000 or 004499 then you need to flash your backup efs.img if you didn't back it up then the best thing is place the original stock rom and run triangle away and warranty it.

Problem solved
Guys I had this problem for about 3 months and today I found a solution to it ..so happy, so heres the deal ...my imei was not broken but I could not make calls .the error that it gave was not registered on network.i tried flashing stock rom , different modems , different roms but no succes until now.
So heres what you have to do
Install the latest version of miui rom .
Download the dmg1 modem and install it after installing the miui rom.
Then install the ariza patch and apply yhe patch that it has.make sure that you have internet connectivity while using ariza patch.after downloading and Installing the patch your mobile will restart and hopefully you will be able to make call.

Flash dmf1 or me4 modem.
Sent from my GT-N7100 using xda premium

Hey thanks for replying .can u post a link to the modems

Flashed both modems still no luck..

If you have flashed ME6 or MF2 based rom. - Your EFS has been modified, No changing Modems(Only XXDME4 or DXDMF1) Backup EFS anyway.
If you aren't getting signal - flash this modem (DME4) or this one (DMF1)
If you made a EFS backup prior to flashing ME6 or MF2 based rom then downgrade to a non ME6 or MF2 ROM then change modem. After reboot you won't have imei. Now restore your EFS.
Even if you do not have a previous EFS backup then try the same procedure, but don't change modem. If you get signal, then you were lucky(happens in case you flashed a custom rom or didn't flash the latest kernel).
If you don't get signal then you could try this-
1)Copy your EFS folder to a safe location.
2)Delete the EFS folder. It will way can't but don't worry.
3)Reboot. You might have factory mode (yellow colour text on screen) and no lockscreen.
4)Copy the backed up EFS folder back. (Replace All)
5)Reboot.
If you can't get rid of factory mode(yellow text overlay) even after recovering imei, try this-
Enter all the commands into terminal emulator one by one and hit enter after everyone. Don't forget to give SuperUser permissions to it.
Honourable Mention -
Thunder Roar Rom has been configured to allow modem change without corrupting efs - http://forum.xda-developers.com/showthread.php?t=2338033

CM 12.1, IMEI Missing?

I was messing around on my ATT I747 phone switching users, when I finally got the new account on the phone, the IMEI is missing. The IMEI and Bluetooth are blank/unknown. I've tried using NV tools, but the *#7284# phoneutil isn't working. I've reinstalled the NJ1 modem, nothing works.
I'm on the 9/4 Nightly.
Does anyone have a suggestion?

When you went into About phone -> Status did you touch the IMEI information row. It actually opens a submenu where your IMEI is displayed. I've had a few moments of panic before I realized that early on with CM 12.1 ROMs. It looks a little odd since some of the other rows like IP address and wifi MAC display their values in little gray text right beneath them.
Also, your EFS folder will always appear blank if the file manager you viewed it with didn't have root access before you browsed into the folder.
Sorry if this is obvious. Just thought I'd point this out because I think the IMEI submenu was new with lollipop. I don't recall it on kitkat, but I could be wrong. Hope you get it worked out.

My IMEI says "Unknown". I viewed the directory with "Root Explorer" and did a full search. At this point, I'd even settle for a service that completely redoes the phone if someone knows of one

You can execute the needed commands from the command line, see here rootzwiki.com/topic/32397-tutorial-imei-backup-nv-with-qpst-us-variants/
Or if necessary suck it up and flash stock.

I suggest confirming that you have both the nj1 bootloader and modem. Perhaps one or the other did not flash properly.
If the bootloader and modem are correct, I would try a different custom ROM or flash the stock Samsung ROM as suggested.

I tried reflashing the modem/bootloader, still no dice. So, I think I'll just go back to NJ1 stock to get it working again, and then go from there. I'll flash the NJ1 bootloader/modem first (again), then the system/boot. I'll let you all know how it goes.
Thanks for the help!

I'm still not having any luck. I did a factory wipe, then flashed the NJ1 bootloader/modem/system image via TWRP from this post on XDA:
http://forum.xda-developers.com/gal...tt/general/ucufne4-to-ucufnj1-update-t2941792
After flashing the system image, TWRP tells me there is no OS when I go to reboot, and It just hangs on the AT&T logo. I'm really not sure what to do from here. I'm reading that if I try to downgrade to NE4 where there are more files in existance that it will brick. I would load the bootloader/modem via Odin instead of TWRP, but I can't find a NJ1 tar file.
I'm very sorry to keep asking for help, but I do appreciate it, and do plan on buying you both coffee if you let me.

The one from Enewman17? That's the one I flashed from the last link I posted. Gets stuck in the AT&T screen, if I flash CM 12.1 the OS works but no IMEI. If I upgraded to NJ2 would that maybe force a redo of all the partitions? Or would that make it worse?

If it gets stuck at the logo, boot into stock recovery and do a full factory reset/wipe.

OK, loaded stock recovery via odin, finally booted into stock 4.4.2 OS. IMEI and bluetooth are still missing. Looked in all EFS folders via Root Explorer, and there are no NV_data files. Baseband and build are both NJ1.

I tried that, but I couldn't get the tool to connect. I'm reading that a Z3X tool can sometimes fix it? I think connexion2005 has one, so I'm asking them. Spending 16 hours on a $100 phone, lol. I'm ready to do something else If you know of someone else that can fix, I'd greatly appreciate it.

Before flashing any s3, I always made a backup of the nv folder.
Fortunately, I have never had to make use of these backups.
I know of no other way to fix the issue.
Are you using a win8 machine? Maybe win7 would work.

I also have lost imei on Samsung s4 m191. I can't seem to find a fix, Is there one?
