maybe you should look directly thread Recover IMEI http://forum.xda-developers.com/showpost.php?p=17587351&postcount=1

I Dont Have An EFS Folder To Change Nv_data
I Guess I Need An EFS Backup From a Working Phone
Or Full Rom With EFS Package

I Hope Someone Upload EFS Package For Me ...

I Need Help ... The Phone Network Not Working At All

i have the same issue.
the post http://forum.xda-developers.com/showpost.php?p=17587351&postcount=1 only works if you have a backup of the EFS files or if you have the EFS folder.
i dont have any of that. what happends if is use the EFS folder and files from another Galaxy (same model)

I Guess If You Flash Your Phone With Another Phone Efs Backup
You Will Get The Same Imei Of The Phone
But The Phone Maybe Work Good

It will work, but, both phones will have the same IMEI #. That's the reason why no one will share their efs folder (files).

The best way for you guys is to send your phones to the service centers, so they can restore your own original imei numbers.

IF There is a Samsung Service Center In My City
That's Mean I Shouldnt Make This Thread Here ... I Made This Theard To Find A Solution
Anyway Thanks

Somebody Help Meeeee

Fix all 0s imei
My device ( Note 3 N900 ) was showing all 0s Imei after i replaced motherboard. So to fix it I rooted my device, go to root, delete the efs folder and reboot. After the reboot you will see a msg restoring settings.... thats how I got the imei back. Please try it at your own risk.

[Q] IMEI lost!!!! please help....

My imei no got lost while restoring backup using cwm..... i looked around the forum and the ".nv_data" method will not do because my efs folder has a file named "essiv" only and nothing else.....
if someone would confirm what files are contained in thier efs folder and mail it to me also i'll be grateful......

I don't think the 'efs folder' of one device can be used with other devices as it contains the device's IMEI number.
Could you elaborate a bit as to what did you do that resulted in the loss of your IMEI number ? It would help others avoid it in future.

Well.... i restored the same backup file couple of times 'coz i was trying to flash a new theme...btw i am on stock indian 2.3.5......
the files in efs folder can be edited using hex editor (read somewhere in the s2 forum...i don't remeber which thread) so the imei no. in that file can be modified...

I noticed after some search~ My IMEI number could be found on my cellphone box (I don't know where is it...)
I'll keep trying to reset and see if sometime efs folder get some files inside of it cause it's always empty.

After that i tried EFS professional Tool but while doing backup it says unable to create archive error status 7
but it created a folder in sd card and contains few file in tar.gz i extracted it and updated with odin again no IMEI
After that i download efs.tar.gz file from XDA site and flashed it again the problem repeated but suddenly i got some files efs folder and efs folder also contains some files and folders it looks like

[Q] Core Plus (SM-G350) - missing nv_data.bin, "Emergency calls only"

Hi guys,
does anyone of you have Core Plus rooted? If yes, can you please look with any file manager to /efs folder? I need to compare whole folder structure with someone who has fully worked phone. Because this phone is showing "Emergency calls only" and I found that my /efs folder is 99% corrupted. My /efs folder has this content (I see there only these sub-folders):
.files
bluetooth
FactoryApp
imei
lost+found
wifi
In folder "imei" I see only these 2 files:
.nvmac.info
mps_code.dat
The problem is that I cannot find there 2 important files nv_data.bin and nv_data.bin.md5 (files needed for successful phone registration to network by IMEI number)
Can you please check and let me know, what exactly you see in /efs folder and it's /imei sub-folder?
Thank you very much !!!!
Rado

PS: I rooted my wife's Core Plus but I see in /efs folder exactly the same structure as on mine. But I cannot see nv_data.bin on her phone too !!! And her phone is fully working !!! Why I cannot see nv_data.bin in /efs folder on Galaxy Core Plus? Does it work somehow differently than other Samsung phones???

So it must work differently than other Samsung models. In ODIN I checked boxes:
Re-Partition
Nand Erase All
Phone EFS Clear
but after flashing oficial ROM I still have my good IMEI and SN. There must be some other partition where are nv_ files stored (through EFS Professional I saw there 19 partitions)

I analysed .PIT file and also used EFS Professional and I see that there is 19 partititons:
cal
syspam_dep
param-spml_dep
rf_cal_file
kernel
recovery
modem
reserved
sbl1
sbl2
param
dtsbk
dts
fota_sig
efs
csc
system
hidden
userdata
Can you please specify on which partition is located nv_data.bin ?

Problem with "Emergency calls only" solved by SW intervention. Thank you for nothing

The EFS is unique to every phone and it shouldn't be shared (and it can't be). If you did the NAND Erase and the EFS Clear in ODIN without a backup of /efs, you have no options to restore it.
