I had this problem and ended up getting a replacement from Samsung.
If you are saying that you've got a blank/unknown IMEI in your phone settings and also when you dial *#06# then your EFS partition is probably corrupted. Your network will probably not let you make phone calls if this is the case.
I don't suppose by any chance you done the firmware "Full backup with CWM to ODIN format" as per the instructions in the sticky thread on this forum? If you did then try flashing that because it contains a backup of your bml15 / efs partition and you will also get your previous firmware back.
If not then with then I would say prepare the phone for a return to Samsung.

Yes, and if so, then DON'T FORGET TO RESET BINARY COUNTER !!!!!
Because else, yes, you'll know it and I'm not in mood to explain it.

I'm pretty sure a standard CWM nandroid backup does not backup the EFS partition.

You can do it with the app Galaxy Toolbox:

http://forum.xda-developers.com/showthread.php?t=1647703
Mine says zero, I'm not sure that flashing from recovery affects the binary counter, may just be download mode / ODIN.
By the way it may be worth trying to restore your CWM backup, especially if its the stock firmware because you'll need to anyway. Severely doubt it will work to be honest, but you never know.

Samsung may check to make sure you have stock ROM, stock kernel, your phone is not rooted and your binary counter = 0. Act on that information in whatever way you deem appropriate.

To be honest I don't know enough about the bml15 / EFS partition and how exactly it generally gets corrupted to be able to answer that but I lost my IMEI without flashing anything.

Flash stock ROM (odexed, not deodexed), UNROOT, and reset binary counter. Flashing and resetting through Odin 1.8x, unrooting through CWM, not stock recovery.
I thought it was described in (one of) the sticky threads.
Oh, and don't forget to remove your SIM and SD card !!!!
P.S.: Your IMEI is still under the battery.

No i don't think it is possible...every phone will have its own IMEI number...

yes and changing the imei is illegal

Take a look at Post #3 on this thread "Originally Posted by Doky73", it describes how to restore your lost IMEI number!!
http://forum.xda-developers.com/showthread.php?t=1781191
Doky73 is the creator of the Galaxy Toolbox app so I would take an educated guess that he knows what he is talking about!
I would think that this would work on an S5830i because Galaxy Toolbox works and I can confirm that I have found my IMEI number at offset 0x80000 of the bml15.img.SAVE file.
Do this at your own risk obviously, I am only passing on information. As to what the technical legalities of it are I don't know quite frankly but obviously all you are doing here is restoring the phone's authentic IMEI number as opposed to changing it for a fake one.
Hope this helps those concerned!

Very useful to people who just corrupt their efs partition

[Q] Bought Unlocked Galaxy Ace EFS Folder

Hi, I bought an unlocked galaxy ace S5830M a few months ago, and I rooted it as well so I can install a new ROM. I've read that I need to back up my EFS folder, but I found out it's empty. Is that normal? Do I need to backup anything at all if the phone came factory unlocked? I've looked for the answers, but couldn't find anything either here or on google that could tell me it was safe to install a new ROM. Any help would be greatly appreciated!

[Q] Can't restore the IMEI (current, generic IMEI)

Hi,
last week, I upgraded a gifted i9000 for testing and fun purposes to CM10 from GB, and for that, I lose my IMEI (I have now the generic 0049990106400). I tried some methods to restore, but no one works.
The first of all I tried was back to GB. it didn't work. still 0049...
Then I tried to flash another GB using a pit file. it didn't work. still 0049...
Then I tried to flash a FROYO (JPU). it didn't work. still 0049...
Then I tried to wipe data / cache. it didn't work. still 0049...[/I
I didn't make a backup, but in my internal memory appeared a backup folder with an efs folder and nv_data file... I tried to restore using root explorer in a froyo version, checking the owner an permissions but it didn't work.
Trying coping only the nv_data, log and md5, but guess what?, didn't work.
Erase entire efs folder,
flash another FROYO checking "clear EFS" with odin... still 0049...
I back to GB but nothing happends...
Then I flash CM9 and CM10.2 but still the same. Can't restore the IMEI.
I checked the nv_data of the backup with an hex editor, and is filled (not 0's).
So... what can I do? I think I've readed every possible solution...
Any help is appreciate.
Thanks .

Sorry, I think I haven't explain right.
Remember that the Galaxy S, the lastest stock rom by Samsung is a 2.3.6 JW6. The jb only exits thanks to CM10. I think the phone was on 2.2 when I bought it... But I've already try to flash a 2.2 but didn't worked. Should I flash the branded version?
I've copied the nv_data and open with an hex editor... But I cant understand anything. Lots of 00's and FF's and sometimes another string.
I have a backup that CM automatic did. But didn't work.

Final Solution:- solve efs problems
When NOTHING works and its going to drive you nuts, just walk down to your nearest Phone repair shop, find out how much they will charge for using their Riffbox to edit/fix the IMEI, and it can be resolved in a few minutes .
on the otherhand, when phone functions without any network issues, having 0049 IMEI is not a problem that needs serious attention, as it is only your Identity and most people don't want an identity that can be used to track their movements

The problem is that I cannot do emergency calls with that imei... thats why I want to change it... I'm worried about if a day I need to make that call... I can not do it...
I've read your topic lots of times... but nothing works... I suppose I must surrender and get the phone to the shop... I was asking if there was some news methods or something...
The only one I can't understand was: "Replacing keystr file ( If missing) in efs > imei folder " I checked another two i9000 that has their IMEI, but they didn't has the file...

yup, Samsung had them in their earlier versions, but as people found ways to edit and alter the NV Data files, they also made it impossible to edit, most people had resolved this issue by using their efs backup files when they jump from Gingerbread to Jbean immediately after losing their network connection, but some have tried everything possible and NEVER resolved until its done with the box

ok, lets give it one more try cause many do not understand the procedure needed to be done when copy paste is involved.
when using root explorer, you need to save after copy paste (means over write existing efs folder with backed up folder) and use exit in menu of root explorer before rebooting.

This happened after attempt on installation of Mackay kernel it worked but I noticed the mobile connection was dead after a while I ran a restore but stil the same problem. The efs folder is empty with a lost+found folder there is also nothing in that folder. When I click manage mobile contract it tells me that I need to put the SIM card in but it is inserted. HELP!!

Is your IMEI still intact or does it begin with something like 0044?

Did you ever do nandroid backup before? If yes, it contains also the efs folder.
BTW, if nandroid backup was done with different ROM, kernel or CWM version, don't try to restore it with Mackay kernel!!
You must flash as furst the same ROM and same kernel and use the same CWM recovery version to successfully restore your nandroid backup.
Otherwise, you could flash some stock firmware and imei usually returns then. People report that Gingerbread JVU usually restores the imei number quite regularly. If your current ROM uses different partitions than stock firmware, you may have to flash also the PIT file to make step back to stock with success, PIT file will do proper re-partition.
Otherwise, there are quite many threads about how to restore lost imei on the i9000. Take some time browsing around.

Great!
Now backup your whole efs folder with the terminal emulator or ADB and save it on several places (different folders on internal and external SD as well as on your PC). It is explained how to do it in my thread.
BTW, on this forum it is kind of nice to click on "thanks" button leftmost beyond all helpful posts.

The same commands like in the terminal emulator can be done by the ADB as well.
You can easily find good threads here on XDA forum how to backup & restore IMEI

But for great tipps you should not forget to "klick" the thanks button ...it doesn`t hurt :fingers-crossed::good::laugh:

I tried re flashing dp2
Followed by flashing factory images of marshmallow
Followed by persist fix from this link : http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576
But still no result... The phone has just gone out of warranty and cant be given for RMA..
Can efs backup of someone else be flashed as I have seen the same somewhere in Samsung galaxy forums

I have the same problem. Unknown IMEI and baseband.
Even I have the same problem. No sim no service error because of unknown baseband and IMEI. Could you please let me know the detailed steps how you fixed it.

The OP got his phone fixed by the guarantee. I would suggest to flash stock firmware from Google's download pages. Get it back to stock and see if the problem persists.

How does the efs get deleted ?

I had an LG G2 that it happened to. Something must have went wrong during the flash. Just happened. Nothing I did wrong, just happened. Started backing up EFS after that. Backed it up during initial flash of N6, save it to Gdrive. Haven't worried about EFS since.
