How can i take backup of my efs using twrp ? Is that possible ?
You can but not sure if it will be a full EFS backup. If You mess up Your IMEI You can use factory binary to fix it.

And from where i can find these factory binary ?

Have you tried doing a wipe? Then use an efs app to restore your efs back up.

Use HC-K Tool, you can get it from the play store.
Don't use Odin to flash EFS.
Enter stock recovery, wipe data/cache. reboot, then use the app to restore the efs.
i cant get into android. im gonn try flashing an earlier rom.

I checked and verified different odin versions, with odin 1.85 efs clear is
not greyed out ; )
im using 3.07 but do you think doing an efs clear using 1.85 will sort this out. ive repartitioned it too

Noo OP did you read anything about flashing with Odin?
All you need was to open stock recovery or cwm recovery, wipe data, then use am efs restore app.

I have a quick question...I have an i337m and have backed up my efs with twrp and efs pro. I am noticing a big difference in sizes. TWRP backs up sizes that are a few bytes and efs pro is just a little over 2 megs. Is this correct due to compression differences? I just want to be sure I have a reliable back up
I have a similar sized twrp backup of efs. I haven't had to use it so can't tell you for sure if it'll work but I trust twrp. Mine is 53kb.

efs is just some personal data/phone info--afaik--why 2mb
my bu is 94kb
i don't think twrp compresses

In backup, just tell it to backup the efs partition only. Twrp gives you options for the different partitions. You just check the box

Hello xda i have a i9505, after some trouble with the imei i have restore it but the phone it's in factory mode.
I have read other post about the problem and how to fix it but i can't follow the guides because my efs folder is empty (I have root)
Thank you

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, please, can someone upload his efs.IMG from sm-n900 ?
I want to write it inside my phone to try with a box if it possible to write after my imei loosed.
I have null/null and no backup from telephone!
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?!
