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
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.
Guys i made this thread for the people who already encounter this kind of problem and for those who will encounter in the future..
PLS DONT POST YOUR IMEI HERE!!!
We only need those who encounter this error...
1st pks dial *#06# in your phone then your imei number will be popup...
Now this is the problem many of android users has this the same imei.
004999010640000

i m deseperate ....
Y_Y
CELICA we have the same problem. did you solve it??
no yet !!!
but i have one idea ....
may be if i flash the efs.rfs with odin may going to work , because to use rootexplorer is vain ...
can you give some folder efs to see if you have some similary code ...
i think this file nv_data.bin have all that need imei and baseband ...
may be some help going to be welcome ...
thank you ...
delete and wrong nv_data.bin and nv_data.bin.md5
rename the good
nv_data.bin => .nv_data.bak
nv_data.bin.md5 => .nv_data.bak.md5
(must have a "." in front the nv_data files)
copy using root explorer to efs folder
change permission as rwx------
change owner to 1001 - radio
change group to 1001 - radio
efs folder permision should be rwxrwx--xx
efs folder Owner should be => radio
efs folder Group should be => system
and factory reset
Good luck
edit: root explorer have to set "show hidden files".

Firstly please stop spamming all the threads. Now just go to the service centre and tell them kies screwed you up and you want a replacement if they can't fix it. If they don't buy it just try to use Google and find out how to restore. If not go to the technician.
Cheers

man, calm down man. you using DXKP9?, where do you locate.
what is the meaning of flash it back?, it mean flash back to froyo?
show us what is inside your efs folder and do you have the nv_data.bin backup?
do your still having the file as below in you backup(the original file)
.nv_core.bak
.nv_core.bak.md5
.nv_data.bak
.nv_data.bak.md5
.nv_state
nv_data.bin
nv_data.bin.md5
forget about the file nv_data.bin & nv_data.bin.md5 in the phone, there are not the original.
or, do you want my help, although im not an expert.
yes
the technician said that he will flash it back to the orignal firmware and that is froyo. im from philippines.
i downloaded root explorer though my phone is not rooted i checked the efs and in properties its size is 0 and i think it is already empty Y_Y

I have the same problem .. how have you solved? :/ thanks
For all who have lost their imei, simply follow this post. http://forum.xda-developers.com/showpost.php?p=48073115&postcount=3
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...
Hi, i have a great problem, because the my Galaxy Core return me NULL imei.
I have tried already with all method that there are in this forum, but i no have success.
in EFS folder there isn't nv_data.bin file but there is mps_core.dat.
I haven't a backup EFS folder, please help me. Thanks!
