I was on CM11 and One day i lost the IMEI number of my phone and lost all network. I think i flashed an update, dont remember clearly. I think the EFS folder was corrupted. I gave the phone to samsung service center and they were not able to fix it. Can any one help me? I dont have any backup.
ANyone? I tried flashing the stock value pack, didnt work
Cm11 suppose to do a efs backup in SD card. Look for it, if found replace efs folder with it and reboot. May work. Good luck.

Oh man!!! I flashed stock over it and there was no sd card, only internal sd! Any other method? Flashing regional stock or something?

I updated to XXBK3 as per the steps mentioned and everything went fine. When the phone booted, the simcard is not getting detected. I have factory reset the phone, changed the sim, tried my sim on another phone (works on another) but not this one.
Revert back to DDKB2 but still sim card is not getting detected. Kindly assist
Update: I have lost all folders in efs folder after flashing XXBK3. Unfortunately i dont have backup of efs folder
The only option left with me now if service center. Since there is no post for efs backup and restoer, i would request if someone can post settings/commands to backup and restore efs.
Hey, maybe you'll laugh, but there do not give any simcard wrong side. Once I flash phone at night and I'm still there giving the wrong side

I didnt understand you.
What i mean is i dont get network and when i try to open Mobile APN, i get message " Please insert SIM..."
This can happen if you have selected the option Phone EFS Clear in ODIN while flashing FW. This would delete the efs folder.
Follow my guide that I sent you for future. I have already backed up mine, but hope I wont need it.
What is the /efs folder? Should I also back it up? Only that folder or all folders under root are to be backed up?

Efs folder contains information about your Phones IMEI no. If you clear it or corrupt it you lose your IMEI and it can only be restored by Service centre if you have not backed it up. Just copying the folder is not enough. You need to back it up in the form that it can be directly flashed to your phone to restore the IMEI and to put your phone back in usable condition, as in india service providers do not support phones without IMEI nos.
Dude can u give us a walkthru of how to back up efs

Is the link given by manu1991 okay in your opinion? According to Post#2, "An alternative to the backup part is to use Root Explorer and zip the whole /efs folder onto your external sd card. (or wherever you want)". Is this possible and reliable? I tried the option to zip folder in "Super Manager" but got an empty file.
No root explorer should not be used to back up this folder. Follow the link and back up your efs folder.

Ok, I tried this and made the tar.gz file directly in my external sd card. I got a file of size 35Kb? Checked with 7-zip, seems to contain all files. Also made the .gz file using terminal emulator and got same size. In Super Manager the /efs folder seems to be 5Mb in size. I also extracted the .gz file and the uncompressed size is indeed about 5Mb. Can it really be compressed to 35Kb or is there some mistake?

yes, it can. If the files has a lot of zeroes inside. BTW here is only 3 files are very big:
nv_data.bin, .nv_data.bak and .nv_core.bak and as I can see they are have a lot of zeroes.

Yes it is compressed. Just pull out the efs folder out of the archive and see check the size, its 5.03MB for me.
Thanks falex and trip
I also made image of stl3 and it is about 6mb.

EFS / IMEI changes to Fake frequently.
With regards to your post on EFS restore, thanks for the excellent instructions I managed to get IMEI back but noticed that it gets changed quiet frequently when I am on any version of Gingerbread so I downgraded my self to Froyo and I notice that the IMEI doesnt change, Could you kindly advise me so to get it working when I am on gingerbread. Does it have anything to do with bootloaders. The restore method I used is to flash via Odin and no other commands there on.
ThanK You In advance.
i have the same troubles
i try many methods
last i failed
now i just play t959 as a pda
I believe the Nitrality app has an EFS backup feature
Good morning from Argentina!
I have a problem to restore my /EFS I have Froyo LUBKB1 (Argentina) coming from KPQ and the /efs is broken.
I have a backup from a functional EFS directory but when I try to copy it with Root Explorer, it seems that it copies it but when I reboot, EFS directory is empty.
Is there any possibility to create the .img with ADB from a directory which is in the sdcard?

Long story short I accidentally deleted my sd cards contents by partitioning it. I luckily have a CWM backup saved to my computer. So I just dragged the file to my sd card via my Mac. When I go into CWM and try to do an advanced restore I get "Couldn't open directory no files found". Simple fix if someone could tell me the proper name of the folder and where it needs to be. As always any help will get you a great big THANKS.
/sdcard/clockworkmod/backup
Thanks for that. In my desire to get organized I renamed the folder CWM Recovery. I'll put it back to normal and let you no how it goes.
ok np bro let me know how it goes
Worked like a charm. All my apps are back. Thanks for the quick reply. Must of been some pretty advanced artillery!
lol...nope just the good smell of that wolf pus**. (if your wondering, its an artillery thang)

WOW. My very first thread has come back from the dead. Sweet.
deeprocks,
Not really sure what your trying to do or what version of recovery your using. But for CWM it will always be under clockworkmod/backup. I am not familiar with your device but if you have internal and external storage the newer versions of CWM let you select where to backup too/restore from. Look into that. Also try asking this question in your phones sub-forum. Good luck.
I'm on aokp build 39 and was using devil kernel. After two days off use my Imei was borked. It's happened twice each time two days. Is there a way to restore Imei on my phone? Without being at a computer? I have the efs file backed up but am unsure what to do with it. I searched Google but couldn't find anything concrete.

This may sound crazy but I have just taken the backup /efs folder and put it on the SD card and used root explorer to copy and overwrite the /efs in the root directory of the phone, rebooted, and everything was fine.
Not sure if its the right way to do it but it worked for me. This was a while back though when I first was experimenting with flashing roms, miui would always screw up the /efs so I would flash back to froyo and overwrite the /efs by using root explorer.
May be worth a try, good luck with it.
I can confirm this works. I used this method on icssgs a few months ago.
Phoned in.....
Wow. Sounds great. Thanks guys. If my Imei gets borked again I'll try that

Lost my imei again today. Just deleted efs folder reboot. Copied my imei folder over reboot and all was well. Next time I'll try just copying my imei folder.
Sent from my SGH-I897
looks like i had some bad luck today. my IMEI reads 0. from what i'm reading if i can restore a nandroid from before this happened it is possible to fix this. as luck would have it just before i realized there was a problem i deleted a whole bunch of nandroids i had because when i made the backups i hadn't cleared the cache and their size was massive. i never even heard of this IMEI problem before so i never made a backup of my efs folder. so i have some questions about what to do next.
1) i have an incomplete nandroid on my external sd card that wasnt able to complete the backup process before running out of room. i know for a fact that the system was backed up. the backup failed only after it tried backing up the data folder. is there any way of only restoring the system part of the backup? i tried an advanced restore to only restore /system and it said md5 checksum failed.
2) is there a way of undeleting the nandroids i deleted? they're on my internal sd card. so far the undelete programs ive found for both windows and android only restore from the external sd card
3) is there any other ways of restoring an IMEI?
help is much appreciated.

WOW. that looks easy. maybe too easy. is there a catch? i had read somewhere that using this method forces the phone to constantly roam but i could be wrong.

It may or may not be "roaming" but as far as ive read the roaming part is cosmetic and isn't really happening. But because you didn't backup thats your only known method to get it restored
so i have good news and bad news.
good news: got the IMEI back
bad news: the mobile network state is disconnected, service state is out of service and mobile network type is unknown
in other words, that didn't fix my problem like i had hoped it would have. i can get 4g service. but nothing else.

Same thing happened to my dad.
Did you reprovision your device after restoring?
You may be able to extract the nv info from your partial backup. How to do this is beyond my pay grade.
Sent from my SCH-I535 using xda app-developers app
honestly now that the imei is fixed you may need to perform a reprovision. to do this, go to a touchwiz rom (any should work) and dial this in the phone:
*2767*3855#
it should fix your data services now that imei is intact but beware it will also perform a factory reset (like the ones performed in clockwork mod before flashing roms) as in it will dlete your apps but it is worth it. it will wipe then reboot (dont worry it will take a while so dont panic if bootanim takes a while) when it is done your data services should be back let me know if it works

I had to do this to get my data services back after injecting my IMEI. Total pain but it was worth it to get service restored. Only problem now is that it shows the phone as roaming but that's no big deal since it's only cosmetic.

so to confirm, it does wipe the internal sd card right? im at work and i would love to reprovision this right now but if it wipes all content on the internal sd card i want to wait until i get home so i can back it all up first. im not worried about a simple hard factory wipe since i have everything backed up with titanium pro.

looks like i was right. it does wipe the internal sd clean. i thought i had read this earlier and i finally found the post i had read: http://forum.xda-developers.com/showpost.php?p=30357448&postcount=2
well i reprovisioned it and... it worked! it has that annoying roaming notification going on but i could care less at this point.
i'm not saying that backing up my internal sd card was a waste of time... but it was a waste of time. as far as i can tell it didn't touch any files on the internal sd. i downloaded titanium backup from the play store and it restored all my apps just like before.
thanks for your help guys! :victory:

Another victory for root!
So i wanted to go back to my stock Indian ICS firmware that i had backed up using CWM.
I was on Vanilla Rootbox 4.2.1 and wiped data,cleared cache and dalvik cache and then hit restore in CWM
Everything went smooth and booted up where I had backup up with same settings and everything
BUT
I lost all my pictures.ALL OF THEM
I dont know how!
I connected the phone using USB to check on the computer but they are all gone. Just the name of the folders and they are all empty.
Ive heard restoring doesn't touch any of the user files on SD card like pictures and videos.
Now what am I supposed to do?
Please Help!

I had purposely kept some pictures in a hidden folder so they dont show up in the gallery.
They are there
also before restoring there were two Clockworkmod folders in my SD card each containing a backup folder.
I deleted one and replaced the other one with my old backup
Did this cause the problem?

Nup buddy. CWM backup doesn't touch any SDcard item. I think there is something you did wrong coz of it all visible files were deleted.
