Hi
My efs folder was deleted and i dont have backup of that folder . I am not able to use my network for calls and text messages.
Android has assigned me a dummy imei 004999010640000/01. Is there any way to make my network work again .Currently its showing "Not registered on network " error.
Please help ...
I think u should reset ur fon it will automatically recover all the efs file.

No, it won't
If you don't have the backup of EFS partition, you are out of luck. Sorry...

I have heard about this EFS and how things get Nasty when IMEI gets corrupt in samsung phones . So Can anybody write a simple steps for me to backing up EFS and restoring it if ever necessary ?
Thank you .
Another thing i have forgot to mention is i am unable to find a Folder called EFS in my / . There is a Folder called Factory which has all ther NV data files.
Hello I have a classical corrupted EFS/ Bad IMEI after flashing rom problem. So I cannot making a calls...
I made a backup of EFS floder but no using software but just copy of whole floder. Now I dont know if it is possible to restore it because backup programs are using iso formats ot tar formats. When i am trying to replace it in Rootexplorer it does not help...
I tried format EFS floder and it does not help either.
Is there any way to save the phone ?
Or another question... is it posible to make "efs.img" from the floder in my computer ?

No i dont think its possible to manually restore it , Rrather you should have followed steps of Backup restore take it service center pay it and get it replaced
or out 100% there is 1% chance to save by flashing proper Stock Firmware .

Solution
Ok I done it with help of "wenousch" from czech forum.
Solution that helped:
1. a) flash Stock rom via Odin. ( Auto Rebot F. Reset Time a Nand Erase All )
b) flash Stock rom via Odin again but !!!without!!! NAND ERASE ALL.
1.5 IMEI check ( false 00sillyness)
2. Root
3. deleting all files in efs floder with root read/write premissions ( using root explorer )
4. adding files from backed up floder to (now empty efs floder in root directory )
5. restart of phone
done - I have good IMEI and I am able to make a calls.
Hi everybody.
I've Installed some days ago a custom rom.
Everything is working fine, but I've seen that my IMEI is changed with generic 00499901064000
even MAC ADRESS is not availlable.
But it seems that everyting is working fine.
Now, I don't rember if I've a EFS backup.
There is a way to rebuild or recover it? (either with that without EFS backup. (I've cell box with IMEI shown)
I've seen that I've a taz file of EFS backup in my SD folder, but it is only 85 byte large.
Thank you very much for help me.
Regards

Bro Goto Your data/radio Folder & Delete nv_data.bin ,nv_data.bin.md5 & Then Goto Factroy Folder & Copy only [ nv_data.bin ] To data/radio Folder & Restart Your Phone Thats it....
Thank you very much.
Solved!
So I found myself wondering how can I make life difficult for myself... I did a software upgrade in Kies on my T805 and now I have a default IMEI...
I was on cm11 before doing the upgrade to 5.0.2
Has this happened to anyone or does anyone have any idea how to fix it?
Many thanks for any reply.
That shouldnt have happened but youre not the first person to state that cm has messed with the partitions. Id stick with stock based roms in future.
Download EFS professional then under the samsung tools tab select other tools then 'Repair NV data from internal file backup'
If youre lucky it will be restored.
Now some friendly advice, ALWAYS make a full backup via recovery before messing with anything custom on your device, especially make sure the EFS partition is backed up.

Thanks for the reply, sadly it restore a different default IMEI ending in /01 instead of /17.
I was 100% sure I had backed-up my efs, turns out I did but on my phone x(.
Any other suggestions?
Try this. Make a backup in recovery of the efs partition.
Boot into android then using a root file explorer open the efs folder then delete nv_data.bin and nv_data.bin.md5 then reboot.
See if this replaces the deleted files with the backup.
