[Help]EFS Partition

Hi everybody! I have a problem with EFS partition, I'll try explain my problem on the better way possible because I don't speak english.
After several flash via odin and CMW the EFS partition is broke.
When I flash the stock ROM with odin the IMEI is there, but when I flash a Custom ROM the IMEI dissapears and I don't know how fix this!
I tried with EFS pro but print an error:
Device Connection: okay!
Root Access: okay!
Detected 'efs' Partition Location:Failed!
Error:Can't Locate Mount Point!
EFS backup Failed!
Also, before all that, I tried with Galaxy Toolbox, and I did a backup but, this backup not works. I know that because I tried restore the EFS partition on the Custom rom and the IMEI isn't appear.
Somebody can help me please? I want restore the EFS partition.
My SGY is GT-S5360L
If you need more information about my phone, just tell me.
Thanks for read!
Greetings!

Soft Bricked i337M. Maybe EFS problem.

I used TWRP to wipe all my partitions under advanced wipe.
I Odin'ed the stock kernel, stock rom and TWRP.
I used TWRP to mount the efs partition, and adb pushed my backed up efs.zip into that partition.
I checked using the TWRP file manager that the files and folders are all in the efs partition.
But after a reboot into TWRP, the efs partition would become empty again, as if I never transfered the files.
And off course, my phone is now stuck at the notorious Samsung logo boot loop.
So why did the files delete themselves after every boot? And is there any way to solve my boot-looping issues?
My current partition size:
Boot (10mb)
System (2135mb)
Data (0mb)
Cache (62mb)
Recover (10mb)
EFS (4mb) it is empty, but still has 4mb?
First question is what firmware were you on before all this? Second question is why did you do all this?
If you were not on mf3 firmware get the stock firmware from sammobile.com and flash that in Odin, PDA. Do not check re-root partition. Hopefully that get your phone to work again.
Wooo hooo it works
Ahh I fixed it! Sorry for the troubles.
I'm glad you got it fixed. But don't mess all that stuff you did.

Yea, curiousity definitely killed the cat. This may be my last of my 9 lives.
Would do sufficient research before attempting theses kind of tasks again.
Thank you. I fixed the problem following several other threads in this forum. Vast amount of knowledge here, just a bit too scattered.

Hey guys,
I think I just bricked my S4 big times. I neither can mount /system nor /cache nor /efs. (I did a efs backup a while ago so I'm not concerned about that) But my phone doesn't boot, TWRP doesn't recognize any OS etc. It happened after I flashed the Domination Theme over Omega 10 (MH8). I have a working backup. Any way to get system, cache and efs to mount again? I really have to have a working phone tomorrow.
No need for help anymore. Fixed it by wiping system and cache manually through advanced wipe options in twrp. After that I was able to restore from my backup

Calling Dr.Ketan need to reach you

Dear Dr.Ketan
since I have recently registered I am unable to post anything on the development thread. I am facing a serious problem. and I am asking you this because I had backed up efs.img 20 Mb and it has helped me restore earlier. but now it's failing to restore my efs. I am explaining the problem below.
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.
1. could you tell me if it's possible to extract the efs.img to the efs files and will it help.
2. do you think there is a way I could retore from your tool using some other method.
i have tried the following things too
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 if you 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

If you don't have a backup and flashing official firmware doesn't help to revive it, nobody else can help.

I finally managed to repair the damage caused by EFS and by when I go to the root explorer I had a clean empty folder EFS whatever I tried to install the new ROM moaning and costum and wipe reset Factory me is always the folder EFS empty my IMEI was correct as it was under the battery, the only thing I had a bad signal and wifi is deenergizes.
To repair the damage I'm desperate to be ordered from stock rom sammobil version 4.4.2 because my phone was slow I then ordered stoc 5.0 then I root the phone and ordered phils latest recover and then I went under the option to mount and put the mount seytem then I have connected phone to a PC and install the adb shell on the computer I Open cmd and typed it
adb shell
su
mke2fs /dev/block/mmcblk0p11 ( skip to next step if fail)
mount -w -t ext4 /dev/block/mmcblk0p11
reboot
This will create a generic EFS files on device
Root explorer/efs and delete factorymode(OFF) and replace with factorymode(ON)
reboot in recovery wipedata factory reset...don
This last what it says to me it was not necessary because I went in and looked exporer root file factorymode where it has been on only one I did factory reset and that's it I got back EFS files and I am so done with all programs EFS Bacup :good:
P : S: because I have a bad signal or should now install new modem in order to find the best signal
