CWM restore failed : data.img not found

Hi everybody,
First of all I want to say thanks to this community because I found a lot of informations here and solved many problems I had.
I searched all the day and I don't know what to do with the issue I get now...
I decided to install JellyBlast V3 on my Galaxy Y GT-S5360. Before that I made a backup of my stock ROM with ClockWorkMod (v5.0.2.6) and then I installed JBV3.
All was allright and I wanted to restore my datas only from the backup with the CWM advanced restore. That didn't work (Maybe because I can't restore datas from a different ROM?)
So, I wanted to make a complete restore from the same backup to get all my datas back, but I get the following message :
"data.img not found. Skipping restore of /data
.android_secure.img not found. Skipping restore of /scard/.android_secure.
Restore complete!"
The phone can boot up but my datas are not restored at all.
I explored the backup folder and there is no "data.img"... but in some resolved threads I read people didn't have it neither... and I am a big optimist so I kept searching...
I tried to restore again but with another zip file of CWM (who resolve some bugs) I found here http://forum.xda-developers.com/showthread.php?p=27475895
But It failed again with the same issue.
I read that if the kernel changed the restoring is not possible anymore so a previous kernel have to be installed (http://forum.xda-developers.com/showthread.php?p=27475895 )
To be sure, I installed a stock ROM with Odin by following this http://forum.xda-developers.com/showthread.php?t=1465800
I picked the S5360_XXKL3_OXXKL1_XXKL3 bundle.
Since I installed the fresh ROM I tried to restore datas again, but I got the same issue again...
So, I want to understand why I get this error ?
Maybe flashing with a stock ROM is not enought to replace the present kernel by the original one ?
Thanks for enlighted me (and sorry for my english)

By any chance is your CWM called gt-s5360CWM or something
You have to backup with a clean CWM and restore with the same clean CWM

Indeed, the first CWM I used to create the backup was "GT-S5360_CWM.zip" but the restore doesn't work.
The second CWM I tried is called "CWM_bla_bla.zip" and the restore failed with this one too.
I think the backup I made is not proper
Thank you for your help.
PS : if my backup is corrupted, is there a way to recover at least my contacts with a backup explorer or something ?
EDIT : I think my backup is definitely not good, I made another one with the "unbugged" CWM and It makes more files including a "data.rfs.tar" file...

[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

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

[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

If your phone is rooted then you should have twrp installed
and if you have twrp installed it has an options of what it
can backup when you select "backup" or "restore" and
there you will see an option to only backup efs or backup
other things in the phone like system, data, cache & dalvik.
Select EFS and nothing else if that's all you want to backup.
Good luck, have a great day!

Thanks alot dear.. I already did that in twrp. Is that the only thing which I need related to efs ? Is twrp efs backup is reliable ?

Yep.
But move a copy of the backup to your pc just in case you have any future problems.
