Go to TWRP, go to backup and select only EFS and hit backup. You are done. Optionally, you can also select the Storage path.
Go into twrp and select that partition to backup.
i assume that i can restore it the same way from restore option in TWRP
right?
I wish I could do this, twrp won't back anything up for me. It just hangs.
just did a back up for the EFS folder and restored successfully
thanks guys

Is your twrp flashed or are you just booting it and still have stock recovery?

Can you share the efs backup with working 4g, got the same issue with VoLTE not working.
hi
i had a problem with a moto g5 xt1676, i have lost both imei numbers.
there's a way to recover/restore them?
if i can do a backup for EFS folder, there's a way to edit some file/s (which one/s?) in order to put back imei numbers on?
Thanks

Yes, and i have already restore
I have a sm-n900 exynos and I have lost my imei and baseband during a Samsung flash. I have a TWRP backup, efs.img backup by dr.ketan's backup tool but nothing is able to restore my efs. I have scanned emmc blocks for bricked blocks and all blocks come back as non-corrupted. may be the partition is corrupted .how do I erase my efs partition to rebuild it. I have tired to flash PIT from ODIN but that too doesn't work.
tried this post http://forum.xda-developers.com/show...567133&page=36
but need a guide to identify the partitions and how to rebuild them. by any chance anyone know if I could extract twrp backup to files to restore efs or from efs.img so I can use the nv_data.bin, since tried restoring the backups and it didn't restore I feel the partition might be corrupt and hence not being re-written. so might be I have to rebuild the partitions by formatting as explained in this thread. but I don't know exactly the steps for exynos variant. I tried using terminal on twrp but mkef2 command shows mmbcblkp03 doesn't exist which as I have read in posts is the efs partition on this phone and reboots to twrp recovery. and mmbcblkp12 show filesystem too small and reboots to twrp recovery
Can some one upload sm-n900 efs folder may be can try and edit nv_data in hex editer

Could you provide more details about the backup you have:
- What files do you have? What is the name of these files, and also the file sizes?

If that's your EFS back up, I'd remove it, or someone else is gonna enjoy your IMEI

So it seems you have the correct backup for your device. Some more questions:
1- Can you show the link to the EFS tool you have used to make a backup?
2- What is your difficulty now? You don't know how to restore? Cannot restore? Or you already restored but the problem still persist?
Please be noted that you have to restore ALL efs-related partitions, NOT only 1 partition.
At the moment, my app 'IMEI Backup ★Samsung★' can only restore from the backup that has been made by it. But I will add the ability to restore from the backup which was made by other apps, may be in the next release.

That means the above-mentioned app does not work correctly with the restoring job?
Has your phone been rooted? If yes, I will guide you some steps to restore manually.
Yes its rooted and has twrp recovery . It would be just great if you xould guide me

Hi there!
I just came out of bootloop when trying to move from CM13 to stock rom (COJ5), I needed to remove efs file of my device using (EFS Professional) to get out from the bootloop!
now I just not registered on network! with [emergency calls only] on lockscreen.
Luckily... I made backup of efs using ( EFS☆IMEI☆Backup ) but dont know how to restore it!
that application telling me to restore with another app which is ( Partitions Backup & Restore ) but when trying to restore it ask me to select destination partition ...there i get lost..what to choose exactly?!

I was doing some rather regular restores from TWRP when all of a sudden I lost my Baseband with no [apparent] way to recover it.
I flashed 4.4 and 5.0 stock ROMs. Nothing. I flashed the modem [CP_N9005XXUGBPB1_MODEM.tar.md5] a zillion times. No luck.
I tried flashing this baby, made by a fellow XDA'er:
http://forum.xda-developers.com/showthread.php?t=2507403
It's based on a script that supposedly fixes this issue. Also no luck. Still stuck on "unknown" baseband, no mobile network
Any help is MUCH appreciated. It's 00:18 and for the past 3 hours I've tried to recover from this...
P.S.: I have a full backup of ALL my partitions, so I think I can recover from this. Somehow...

Well, I tried to restore the entire OS via TWRP from my full backup. And now, since you mentioned it, I also tried restoring ONLY the EFS. No go
Do you have an actual backed up EFS folder .

I have these files among my TWRP backup files:
efs1.emmc.win 14 MB
efs2.emmc.win 3 MB
efs3.emmc.win 3 MB
I always back up all partitions.
Upon restore, I can see an "efs" folder in the root (along side etc, acct, mnt etc) but the folder is empty.
I have NOT taken any manual backups of the efs folder (as in copy the folder itself), nor did I use a tool such as EFS Professional. I found out about these too late
I was hoping that TWRP does what it says when it "backs up" data. Am I to understand that I just destroyed my phone because TWRP didn't back up my efs?
Sadly thats not an EFS backup .
A shop with a JTag should be able to fix it .

Ouch. Much appreciated, despite the bad news .
I'm quite angry on TWRP now. What did they mean by "efs" backup, if there's no actual backup?
So this means they have to access the phone motherboard to do... what? What should I ask them to do? Flash me a new IMEI?
i installed a firmware and had a command to delete all. but I have a backup made with TWRP. is there any way to restore the IMEI?
You will have to flash your stock firmware.

sorry I'm new. I have to search again for a firmware? my backup doesn't work?
If you have a backup in TWRP, IMEI is in "Efs" part.
If you don't have that, flash the stock ROM again and that is how we were going to get your code back.

right. I have 2 separate backups from 2 different years. but neither has a folder or file named efs

It doesn't need to have a folder which is under that name. You have to select the backup from your TWRP recovery and there you will find the folder. You cannot find it using file manager.
If you cannot find it even in TWRP recovery when restoring backup, you need to flash your original ROM and your IMEI number will be back.
