[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!

[SOLVED] BASEBAND "unkown" EMEI "unkown" - EFS Backup available

Hi all,
i had to use "Clear Phone EFS" in Odin to get my 9005 back working - i thought: "Hey no problem i have multiple EFS backups..."
But now even if i restore my backup in TWRP or via the Windows Batch Backup Script, my Baseband and EMEI and EMEISV is still "unkown"
Can s.o tell me the steps i need to do, to rewrite my Baseband and EMEI with my available EFS backups?
What i have:
- EFS Professional
- 2 different EFS backups in TWRP
- 2 windows back tool EFS backups (i mean this script: http://forum.xda-developers.com/showthread.php?t=2447342)
- Working WIFI
- Working BT
- Stock N9005XXUENA6_N9005OXXENA5_N9005XXUENA2_OXX file(s)
- Stock N9005XXUENB4_N9005DBTENB1_N9005XXUENB1_HOME file(s)
- Stock N9005XXUENB7_N9005DBTENB2_DBT file(s)
- Odin + 9005 PIT Files
- Correct SerialNumber in DeviceInformation->Status
I'm on the new Bootloader and KitKat OS
Thank you very much for all your help!

On the N9005 the IMEI is no longer on the EFS partition (mmcblk0p11) but instead in some other partition - I think mainly in MS1 (mmcblk0p12) with something else (backup?) in MS2 (mmcblk0p13). There might be something else in mmcblk0p17, mmcblk0p18 and mmcblk0p19.
If you do not have any backup (including a larger "debrick backup" - search for that post) you can try to see which one of the partitions I listed above was supposed to be the backup of what; and if that fails there is a more complex procedure described somewhere in a thread on XDA - involving manually hex-editing your SN and IMEI from under the battery or the original box of the phone.

ok thank you - bad news

What about the "unkown baseband"? How can this be fixed?

Ok a managed it to get all back working, incl. baseband, emei etc (but you need a twrp efs backup with all 3 efs partitions --> simply a twrp backup)
If some others have the same problem, here you go:
I think some other partition was corrupted and thats why the twrp efs restore didnt worked (just a twrp efs restore).
I did following: (you need a efs backup!!!)
Folow exactly this guide http://forum.xda-developers.com/showthread.php?t=2567133: and do all partitions, DONT! skip the efs partitions (we have a twrp backup)
Now some further steps are needed:
IMPORTANT:
1) When you put in back your battery, boot back into twrp and restore your TWRP EFS Backup!! Dont boot in the OS!!!!
2) Then reflash with odin a stock based rom without any other checkboxes (NO EFS PHONE CLEAR, NO NAND ERASE ALL!!!!), just a normal odin stock rom flash
3) Let the phone reboot into OS and YES: Baseband working again, EMEI working again

Bro whats a twrp efs backup?

Team win recovery Project. Its a revovery and a twrp efs Backup is a Backup from the 3 efs partitions in twrp

Hi, I have the same problem as you did, my baseband is showing unknown and the imei is showing null. This happened when I was installing a different modem via ODIN. I do have a EFS backup, however, it was done with philz recovery instead of TWRP and has 4 files ('efs.ext4.tar'; 'efs.ext4.tar.a'; 'nandroid.md5'; and 'recovery.log'). Are these the same that you would get with a TWRP?
I also have another efs backup that I did which is one file only, 'efs_20140531_122400.img'. Would I be able to use this for anything?
The phone is an N9005 on Kitkat.
Thanks for any help in advance and please let me know if you need any other info.
Cheers
--------------------------
Just to let you know,
I had tried flashing flash latest full UK NF4 system before and it didn't work. However, desperate as I was, I went again and gave it another shot and incredibly enough, it worked!!!! Phone is back together again!!!! Yeeahh!!! There goes an incredible load off my shoulders. I guess I did something in between that actually helped, we may never know.
Cheerio

Hi Hundsbuah,
I upgraded my Note 3 9005 Hong Kong Version 32 GB from Jelly Bean to KitKat without taking backup of EFS and now I have IMEI Null and Baseband unknown. I found backup of other user's note3 EFS at "http://forum.xda-developers.com/showthread.php?t=2447342". So, if I tried EFS restore from above link will it resolve my IMEI null and baseband unknown issue?
Regards,
Asif

[Q] SM-N900 EFS nv_dat.bin corrupt EFS etc Pease HELP!!!!

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

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

[Q&A] Restore EFS from Nandroid Failed (Solved)

Hi Everybody,
I'm really disappointed. For the second Times, I've corrupted my EFS partition. IMEI is empty, as the baseband...
The first time that I had this problem, I could restore the EFS using the fabulous fix from Fireasusman : http://forum.xda-developers.com/showthread.php?p=47014662#post47014662
But this time, It didn't work.... I'm really really sad.
Before trying to restore the stock firmware ( My problem was coming when i tried to restore stock firmware before to sell it) i made a Nandroid backup with TWRP recovery. I've an EFS/MODEM backup in this Nandroid.
When I reboot into recovery, and go to restore, I can select EFS, and it seems restore It. It wrote : Restoring 2 partitions/Restoring EFS/restoring EFS2/restoring EFS3/EFS Done/Restoring Modem/ Modem Done...
But after reboot the problem is Still There...
I'm really Angry, I lost 400$ and I don't understand why my Nandroid Restore of EFS failed...
I also try to flash modem with ODIN but it still Failed.
Note: I was an temasek CM12 (android lollipop).
Thank you very much for every help.

1. Flash STOCK ROM and take a look how it works. Sometimes only flashing it recovers the EFS folder.
2. Next time use this APP for backup/restore your EFS.

Really thanks for your help.
But i've allready try to restore stock ROM. At least twice. But efs is still corrupt. And the phone never arrive to boot...

About how many time I can consider that flash stock ROM will not repair my EFS partition ?
I've allready done twice...

Ok... I solved my problem.
As I explain in first post, I'had a EFS backup with a Nandroid Backup. But when I restore with TWRP, the problem was still there. No pin, No baseband etc...
I only delete the EFS folder using root explorer. I reboot, and it was OK. EFS folder was rebuilt automatically.... No more complicated than that...

Good finding

Because the IMEI is not stored in the EFS folder.

How to backup IMEI (efs parition) ?

Hi folks
How to take a backup of the efs partition ? I am not seeing it in twrp partitions list for backup. Any help is highly appreciated.

If you are looking for a quick solution, you can try the app(s) available in play store. Requires root and I believe you are rooted.
Nandroid backup through TWRP will save EFS with other partitions. Or you can try terminal commands through TWRP for backing up the modem files. Don't ask me for commands, I will probably mess up the code !
