Hi,
I have a Google Nexus S (Model-GT-I9020T made by Samsung). I flashed it with CyanogenMod and messed up my IMEI number. It now shows a generic number. I am from India and I can't connect to my carrier now. I have searched for days and at the end I feel that ODIA can help me to restore my IMEI.
I have restored my phone to Android version 2.3.6, Build Number GRK39K. The phone has CWM recovery, rooted and Root Explorer and Terminal Emulator installed. My EFS folder has nv_data.bin nv_data.bin.md5. But imei folder has only one file .nvmac.info.
Root folder is empty and I also don't have any folder called factory. Can you, please, please help me restore my IMEI number to whatever number is written under the battery?
Thank you,
India.

Hi all,
I have been using Captivate for a while, rooted and flashed with new rom's etc....now I want to unlock it to use on other carriers and cant find /efs/nv_data.bin file...looks like I might have deleted this partition...
is there any other way to unlock with out the original nv_data.bin file? my phone does show me correct IMEI number so..is there a way to find the unlock code based on that IMEI number?
appreciate all your help.
I did a master clear and flashed it back to original rom with Odin but still can't seem to find /efs/nv_data.bin ??
I only have 3 folders now..
Android
DCIM
sd
You can not see the file with the stock file manager. You need to root then use either root explorer or super manager
MIUI
search for galaxy s unlock by Herloz in the market. i have a used cappy with a corrupt nv_data.bin, and using super one click returned the fffffffff code. the app worked a treat and the unlock has stayed thru a few roms now. it doesn't repair the code but does the trick.
This The First Time I Flash My Device
Accidentally
I Checked On [ Phone Efs Clear ] in [ Odin Multidownloader ]
After The Device Finish Flashing
I Found That My Imei Changed To 000000000000000
And I Didnt Found The Efs Folder
Even After Flashing My Device To Another Rom
There Is No Efs Folder
Someone Told Me That i Have To Get Efs Backup From Working Device
I Hope Someone Help Me Here .... =(
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

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.
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...
Picked up a used infuse and while flashing away lost my imei. Of course I didn't back up my efs file as recommended everywhere. While messing around I stumbled across this method.
1. Write down your imei.
2. Factory reset phone.
3. Make sure you have root and a root browser installed. I used the root browser in ROM toolbox.
4. In root browser go to efs folder and open it.you will see a file called crypt prop_data.
5. Open the file to edit. Only text in file should read null.
6. Replace null with your imei you wrote earlier.
7. Reboot.
Imei should now be restored. I've only tested on my device. Recreated flash scenario 3 times losing imei each time. Repeated above steps recovered imei every time. Hope this helps someone.

Any troubles with IMEI not saving?
Thank you for adding this information. It is really helpful as a lot of us have to deal with this IMEI problem. I do have a question. Have you experienced, or has anyone experienced the situation where the IMEI number is saved, but upon returning to the folder, the same old "NULL" shows up? I've saved it several times to no avail.
Any thoughts would be very welcome.

Ok for friends who have completely corrupted EFS folder then the phone is "without imei" just write this file via ODIN in PDA
mega.co.nz/#!lxdgHCpL!UXThp1fT2HKrTJA_G1czASiKjkkrit-FjVJSwiexPFQ
This file restores EFS with a standard imei 004999010640000 then proceed to restore your imei staff with the method you prefer.
I used Z3X.

Thank you., I got this file with Flash Odin software, but unfortunately the problem is not resolved or you have any suggestions?
After flashing the above file, you need to restore your own imei number, to get the network working. Check the bill for the phone, or the box it came in to find your imei number.
Ok my imei peinted in phone box and i have this number.How to restore this imei number??
Use Z3X. Search here in xda forum for more details.
