Use this version of EFS pro, newer versions don't play nicely with our phones
If you make a standard nandroid backup, but skip the data backup, you can restore your EFS anytime.

Hi,
Of course you can use GalaxSim Unlock to restore your EFS backup. The backups made by other tools for this device will contaion the same data. By default, it will restore the EFS folder. If you check "advanced mode" in settings, you can chose to restore the whole partition.
Unfortunately, I've had a look at your data : you seem to have lost your stock EFS data (I suppose you IMEI might be wrong). Unfortunately if you don't have a backup made before you lost it, you can't do much to restore your imei.

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 .

By the way same thing happened to me and I have .tar.gz file type as backup. This backup was taken using Aroma while installing rom. How can I restore this backup please?
Thanks in advance,
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.
Hello,
I looked at other threads regarding the EFS partition but none that really answer my question. I hope it's not a stupid question...
So basically, I was trying out a new ROM and made a backup using TWRP. I inadvertently backed up the data partition separately, but I figured that didn't matter. I then backed up all other partitions (EFS and Modem included) in a separate file. I didn't like the new ROM I tried so I went to restore my backups. When restoring the "everything sans data" backup, I kept getting an md5 error, even though I didn't create an md5 upon backup nor did I ask it to look for an md5 on restoration. I decided to try and restore everything except the EFS, and it worked. Phone is up and running and it doesn't seem like there are any issues. Can someone please explain this to me? I'm assuming the existing EFS partition was never changed, so restoring everything but the EFS should still result in a complete system, but can anyone suggest a reason why it failed when trying to restore EFS with everything else? Thanks!
Hello XDA, I am on the process of moving from stock 4.2.2 on my DUOS to a Custom ROM, I haeve my device currently ROOTED, with CWM, SU app, ROM has been backed up using CWM/ROM Manager, Stuff synced with Google, Apps backed up with Titanium, need to be sure I have a recoverable EFS backup.
Now here is where I halted the process because I have been reading quite a lot and talking to people used to flash their phones but none of them have a GT-I9082 and we aren't sure that about what partitions are vital for an EFS restore.
I know I have backed up using EFS Professional my EFS partition but other than that no other partition was available (Used International Variants option as filter, since my device isn't listed by default). I added manually a filter named ftaer my device, the way I made it was reading the PIT file and selecting all the available partitions, but I'm still not sure whether that would suffice to recover a broken EFS.
I would really appreciate any input from people who already recovered their EFS successfully either using EFS Professional or any other method, please tell me which partitions have you backed up.
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.

You may as well post it as its not a valid imei, it's a generic imei.
Is it 004999010640000?
Hi, I just flashed AICP and found that the VoLTE is missing. I've an EFS partition backup taken with TWRP earlier. But that file is an IMG file. When I try to restore that IMG file using TWRP it asks for the correct partition to restore. All I can see are:
Boot
Recovery
System image
Vendor image
Firmware (image)
Splash
Could someone please say to which partition should I restore it?

Your efs backup should be named something like efs.emmc.win

Nope, the file name is efs_backup.img . How to restore it?
Could someone please help? I found tutorials only to backup EFS partition using TWRP. Didn't find any for restoration. At least someone please post the link to it? Googling didn't give any results.
I've already asked this on XDA before, but no one replied me. Here's the link: https://forum.xda-developers.com/le...te-problems-custom-roms-t3744291/post77703907
If the EFS in IMG file format can't be restored then what's the point of backing up the EFS using TWRP? I always QPST the ZUI ROM whenever I switch to a different ROM. This time I don't have my PC with me, that's why I'm asking this. If we can't restore this using TWRP then at least please confirm it. Then I will wait until I get my PC.

Efs Backup created through twrp contains .win format and you can recover only if it's in that format. Or if you are damn sure that you have created backup through twrp then find that version of twrp and then try to restore.
You dont have to flash the file, you have to restore it using twrp
Make a backup of your current efs through twrp
You will find it in the internal memory in twrp folder
Go into the folder, keep going in till you find the img file of your current backup, replace it with the previous backup.
Then boot into twrp md go into restore, you will find the option to restore the efs partition
