After 2 days and a lot of head scratching i've managed to finally get my phone back after a random corruption of my /efs folder... heres what i did:
the important part: you need to be able to access /efs with root explorer etc. and check the 2 files; .nv_data.bak & .nv_data.bak.md5
in order for this to work, these backups must be dated earlier than their .bin counterparts... in my instance, the .bins were modified sep 14th 2011 @ 09:45am (the time i rebooted the phone when i noticed i had no signal and the corruption occured), but my .bak files were both dated dec 31st 2010...
in adb shell, i ran
Code:
su
busybox tar zcvf /sdcard/efs/efs-backup.tar.gz /efs
i then downloaded 7-zip, used it to open the .tar file
i deleted the corrupt files;
nv_data.bin
nv_data.bin.md5
i then renamed;
.nv_data.bak > nv_data.bin
.nv_data.bak.md5 > nv_data.bin.md5
after closing and saving the changes, i then went back to adb shell and ran
Code:
su
umount /efs
mke2fs /dev/block/mmcblk0p1
mount -w -t ext4 /dev/block/mmcblk0p1 /efs
busybox tar zxvf /sdcard/efs-backup.tar.gz -C /
reboot
and voila! i was prompted to select my network provider, check status and all my IMEI, IMEI SV and other info was back to normal!
hope this helps someone out there, as i had a hard 2 days trying all sorts of different methods to get this working and was getting to the point of giving up...
good luck
Dickie.
Original post
right, i've been banging my head against the proverbial brick wall all morning over this... this is the score;
This morning i had no signal - 0 bars with a little x from memory
i switched it into flight mode, thinking when i brought it out it might reconnect
when i entered the power menu again, the flight mode button was greyed out (but it said it was switched on), also 'Call' in settings is greyed out, 'flight mode' is UNticked in 'wireless and networks', and trying to enable bluetooth returns an 'In flight mode' message...
reboots, cache/dalvik/full wipes, reflash of rom, flash of stock from odin inc. modem etc all do nothing...
In settings>about phone>status i am missing a lot of info, including phone number, network type and IMEI/IMEI SV...
i can enable wifi, and i downloaded an airplane mode toggle widget, which re-enables 'call' settings, bluetooth, and replaces the aiplane symbol with a circle with a cross through it...
I'm pretty stuck at this point and all i can think is that perhaps the EFS has become corrupt... anyone got any ideas?? all suggestions appreciated... in the mean time i'm going to look into the EFS stuff which i have no idea about yet lol
cheers,
Dickie.

yes you have corrupted /wiped your EFS or IMEI ,
If you backed up your EFS its not a problem just restore .
Plenty of restore EFS posts around broken IMEI etc .
jje
I'm looking in the EFS folder now, all seems to be present, but i am missing my IMEI (*#06#)...
not sure how this has happened, not done anything recently... very strange... but it does seem to be specifically the IMEI as my macs etc all all there and ok...
not backed it up so i'll see if theres a way around it :/
Cheers,
Dickie.
This happened to me 3 days back. Was sure I needed to send it in for service (reflashed and everything without avail) but then someone mentioned the EFS folder corruption issue.
Thankfully, I bumped into Rawat's thread a few weeks prior, and promptly backed up my EFS then.
It only took about 3 minutes in the terminal to fix the problem afterwards, no pc needed.
No EFS backup would usually mean a trip to Samsung service.
I got the same problem sice yesterday... tried all with the help of some guys here but nothing helped!
@eiraku: Do you like to explain me how you fixed the issue in the terminal, because my was /efs folder was also backed up but overwriting doesn't helped
ive just realised, my nv_data.bin & nv_data.bin.md5 have todays date in root explorer, i'm guessing thats a last modified date and that happend during the time in f*cked up, but the nv_data.bak & nv_data.bak.md5 are dated 31 dec 2010...
does this mean all i have to do is rename those backups and all should be sweet???
cheers,
Dickie.

Sounds hopeful.
I'd suggest you take a copy of those backups & put them on an external device before renaming anything.
i took 2 backups of the entire /efs folder, then renamed the bak files to bin, but i'm having trouble copying or pushing them to /efs...
anyone know how to mount it as r/w, i cant through root explorer and not sure via adb
any help appreciated...
Dickie.
---------- Post added at 06:24 PM ---------- Previous post was at 05:40 PM ----------
ok, i have tried the following:
busybox umount /efs
busybox mount -o rw -t ext4 /dev/block/mmcblk0p1 /efs
busybox mv /efs/.nv_data.bak /efs/nv_data.bin
busybox mv /efs/.nv_data.bak.md5 /efs/nv_data.bin.md5
then when i check with root explorer all appears correct with the baks gone and the bins dated 31 dec, but upon rebooting its all gone back to the way it was before...
again, anyone got any ideas??
Dickie
Did you found a solution? I'm thinking about going to a service center
i'm trying to work out how to get the damn /efs folder to remain r/w...
everytime i change the files, moments later its reverted to what it was...
just trying a different insecure kernel to see if that helps... even sometimes whilst i'm deleting/renaming the files it suddenly becomes read only again...
really wish someone who knew how to make either an update.zip or an Odin flashable tar could do so with my renamed .bak backup files to overwrite the original bin files...
Dickie
happened to me but the problem solved in a couple of hour without doing nothing
tried making an update.zip but i get a status 6 error... stuck again...
could anyone take a look at this for me?? ive been on this almost 18hours and im tired and need to sleep...
again, any help appreciated!

This happened to me whenever my phone restarted after cleaning the battery stats with Battery Calibration app (by NEMA) from App Market. At first, I restored my nv_data.bin file that was backed up (efs backup), but it continued to have same problems for next few reboots...
BUT!
I believe I have a possible simple remedy for this problem:
1. Turn off phone.
2. Remove SIM.
3. Turn on phone.
4. Wait until phone fully boots. (my phone did not detect SIM card and had emergency mode available, showed normal information in About Phone options)
5. Turn off phone.
6. Re-insert SIM.
7. Turn on phone.

Yesterday i updated kernel on Revo 2.7.1 via KitchenPro app (for infos from CFROOT_KI3.zip to CFROOT_KI3_v4_2.zip) everything seem fine but this morning no imei, no baseband...
I search a lot before finding your thread (i think this one should be sticky !)
Your procedure is clear & simple (and hoppefully work in my case).
Thanks again dickie2007
PS : It seem since the serie KI* there's a lot of similar problems (i saw many thread during my research this morning about this kind of trouble)
If u flash different carrier branded firmware in CSC & do not set it correctly,
u may find that u can't see ur IMEI via *#06#.
Don't worry. It is still there. This is my way to solve it.
(just several seconds and without efs backup)
1.edit carrier branded code in "/efs/imei/mps_code.dat" to meet what you flash.
Ex. My S2 is CWT in the beginning, so I flash a CWT CSC and edit the code to CWT
2.use *#06# to ensure if IMEI could be shown correctly
3.To double check, u can use *#272*imei#. If u can reset carrier branded code then it is done.

Does this also work even if baseband is shown as unknown? I flashed a stock ROM with Odin and lost both baseband and IMEI. dickie2007's method didn't work but maybe yours would have...
Hello
I have a China Mobile galaxy gs3 i9308, and the imei no. was changed to 0000000000000/null because of rom flashing (I think).
Now I am not registered on the network, so I have to change the imei no. back.
I tried several tutorials online, but seems like they're only for the galaxy s.
I tried the 9 step guide but I can't find the .nv_data file in my efs folder.
Can anyone help me or point me in the right direction?

Thanks for the quick reply. But I followed the written version of the guide and it only works for galaxy s? Because in my nv_data.bin file there's no line 00188008 in hex editor.
this is the link to that thread: http://forum.xda-developers.com/showthread.php?t=881162
The video poster also said it only worked for galaxy s.
Any other ideas?
hey, I have the same problem, SGS3 with wrong imei 0049.... i lose my efs file, someone can help us?
You could try flashing stock rom, heard that this sometimes restores imei, not sure if it works on s3
Also, check if the rom or kernel you flashed created a eggs backup, some do

i have the same problem i cant fix my imei, after flashing the phone it changed to 00499.. it made no backups and no nv_data.bin.bak
If the efs folder havent been backed up, what can i do? I tried changing the nv_data file like some tutorials here explain, but no luck(tried couple of times, it defently not compatible with my galaxy s3), i believe these tutorials are for erlier galaxies.
Please help!

Did you back up the efs folder before you flash your device?
I understood that imei numbers were hardwired into the phone. And changing them n having the equipment was illegal. This is what the networks use to bar your phone if it gets stolen.

How to restore your IMEI number on SGS3 (GT-i9300)
I deleted my IMEI number when flashing roms a few days ago and it was showing as 000000...
I searched everywhere for a recipe of how to restore it and could not find one that would work. The closest that I got was a brilliant post (see link below) describing how to restore the IMEI on a SGS2 i9100. After following this recipe, I was able to restore my IMEI number to 0049 .... which is just as useless as 0000....
It took me a couple of days of research (and HUGE thanks to everybody whose previous research I was able to use) and I finally succeeded in restoring my IMEI using the 9 step process that I describe below. I can't guarantee that it will work and I do not know if it will work on any device besides the SGS3 GT-i9300 (international SGS3), because this is the only device that I have and was able to test the process on.

Download your original firmware using check fus downloader (http://forum.xda-developers.com/showthread.php?t=1032437&page=18)
You need:
-EFS PRO, a brilliant little program for Windows used to backup / restore the efs folder as well as recover / repair the nv_data*.bin files.
-Windows
-Windows USB drivers
-Rooted SGS3
-Root explorer.apk
-Original phone firmware (actually, you only need the modem.bin file, so once you download your firmware package, you can just extract the modem.bin file).
-Odin or Heimdall
Your phone's IMEI number is stored in the ".nv_data" file in the original shipped efs folder.
Process:
1. make a copy of your EFS folder using root explorer and store it somewhere safe (on your SD card and external SD card should do it).
2. delete the EFS folder from the root of your phone using root explorer.
3. reboot the phone
4. open root explorer and go to the EFS folder (yes, it is still there! The Android OS has generated a new one for us) and delete the following files:
nv_data.bin
nv_data.bin.md5
nv.log
.nv_data.bak
.nv_data.bak.md5
nv_data.bin.bak
and the entire IMEI folder.5.Now go to your backed up EFS folder on your sd card and copy the IMEI folder and the " .nv_data" file (note the dot) to your new EFS folder.
6.Make another copy of the ".nv_data" file in your new EFS folder. Rename one of them to "nv_data.bin" and the other one to "nv_data.bin.bak".
7. Connect your phone to your PC and start up EFS PRO. After your phone has been detected, press the "Repair nv data" button to correct the ownership and permissions.
8. Reboot your phone into recovery mode using the three botton combo and flash the original modem firmware (the modem.bin file that you extracted earlier) to your phone using Odin (use the "phone" button for the upload) or Heimdall (use the "radio" partition for the modem.bin file upload).
9. Reboot the phone normally and your IMEI number will be restored and you will be able to connect to your mobile network again
Good luck and let me know how it goes

Hi there
You need YOUR IMEI number back (which is not 00000... or 0049...) it is the one under your battery.
If you followed all the steps, then it should have worked.
One extra thing that you can try is if you did not flash your original phone firmware (and you only flashed the original modem.bin file) then do this step first.
And then work through the 9 step process, ignoring the step where you flash your original firmware (because you will have already done it).
Good luck and let me know when it works

Hi,
after flashing a modem, i got a "fake imei", and i can't connect to my provider.
After some search i found a thread to recover:
- copy esf to sd
- format efs
- restart
- copy imei folder and nv_data.bin.bak (from 2010) to nv_data.bin
- restart
i'm still stuck with this imei.
Is there something else to do ?
i tested this process with android 4 samsung, and 2.3.5
do i have to be in the same release than first time i used the phose ? (2.3.3)
thanks for advises/help.

Hello,
Thanks for your suggestion,
i tryed that yesterday, but as i have no backup how can this solve the problem ?
should i rename something ?
i did the few steps to format and reinstall. but it still the same.
I noticed after flashing the modem, the timestamp changed from 2010 to 2013 on the file nv_data.bin and .md5
i had a .nv_data.bak from 2010 is this the correct one ? (in the efs folder)
this is the one i'm trying to restore, if possible/correct ?

I noticed after flashing the modem, the timestamp changed from 2010 to 2013 on the file nv_data.bin and .md5
i had a .nv_data.bak from 2010 is this the correct one ? (in the efs folder)
this is the one i'm trying to restore, if possible/correct ?

If you tried SGII_Repair I assume you've already tried this and didn't work, right?
If so, try going back to previous MODEM (back EFS folder with HC kTool first).

Not the original ROM, the last modem you used before flashing the one that got you in this mess.

Hi,
after flashing a modem, i got a "fake imei", and i can't connect to my provider.
After some search i found a thread to recover:
- copy esf to sd
- format efs
- restart
- copy imei folder and nv_data.bin.bak (from 2010) to nv_data.bin
- restart
i'm still stuck with this imei.
Is there something else to do ?
i tested this process with android 4 samsung, and 2.3.5
do i have to be in the same release than first time i used the phose ? (2.3.3)
thanks for advises/help.

Okay, so you've got 2 EFS folders, one in your SD card and the other one in system's folder, all same files in each folder, am I right?
the copy i have is a backup i did after the problem.
not sure at this time, i'm thinking to restart fresh, i'll copy /sdcard/efs to /efs and replace.
Then i'll try again gs2_repair to see if i missed something.
Woot working get my imei back and online
many thanks !!!!
backed up with ktool now

LS6 didn't work for you?
REMEMBER to BACK UP the EFS folder!
LS8 and LS6 make my imei disparear if i use getril to have the same ril/baseband
if i use ril xxlq6 with the modem LS8, my imei come back (*#06#)
but reception is very poor
i'm using CM10.1 nightly 04022013
now i'm using xxlq6 baseband and ril; it is most of the time full strength, then sometime fall to -130 DB 0 psu
but if i start a call to my second phone, it pass from -130db to full strength
Bought and activated used phone 2 weeks ago. Phone worked fine thru Friday night. Woke up Saturday to find I could not connect to cell network. Call to carrier revealed my IMEI number does not match the number they have. Somehow my phone IMEI changed to 350000000000006. Internet search revealed many others with same problem. The main difference between their situations and mine is the fact that in almost all of their cases their phone was rooted and they flashed many different ROMS to their phones and something obviously went wrong. My phone is NOT rooted and I have not tried to modify anything. Simple as that. Went to bed working, woke up broken.
I have now researched this the last few days and have no clear answer. Is it possible to set my IMEI back to my correct, legal,clean and not blacklisted value? Any help is greatly appreciated.
My guess is without a backup of the original, you can't do anything about it. Best bet is probably return it to the store you got it from and get a refund/exchange.
Edit:
Fastest and safest bet would be refund/exchange.
Little research has shown other people had a similar issue. Check Nox to make sure the phone hasn't been rooted before, if it has, you know what happened. If it hasn't, chances are the phone was flagged as lost/stolen after being sold (if 2nd hand).
As for a fix, I found this:
http://forum.gsmhosting.com/vbb/f898/g925f-imei-350000000000006-a-2044425/
Recover corrupt IMEI (without prior EFS backup folder)
Items needed
Root Explorer
Efs folder (no need to have a backup of this prior to the disappearance of IMEI folder, but it has to be this folder on the phone)
Obviously having a rooted phone
Instructions
1- With the Root Explorer to back efs folder to the SD Card
2- For safety make a second copy of the folder to the PC
3- Once both copies made to proceed to erase the original EFS folder on your phone
4 Restart the phone
5- When you start the phone, it will automatically create a new folder EFS, Root Explorer to delete the files and nv_data.bin.md5 nv_data.bin found inside the new EFS folder.
6 Copy the folder from the SAI IMEI folder we saved on the SD card and stick it on the new EFS folder created in the root directory of your phone
7- Since the SAI folder we saved on the SD card .nv_data file copy, paste into the new folder EFS generated in the root directory and rename it nv_data.bin phone, then recopy again .nv_data file rename it nv_data.bin.bak
8- With Root Explorer /efs/nv_data.bin change the owner
9. Restart the phone
If all went well you should have recovered the IMEI can check if recovered by entering * # 06 # on the phone dialer.
Thanks for the response ProdigyThirteen.
The Knox is clean 0x0. Everything I have found says the original IMEI is clean and not flagged.
I will definitely look into the procedure you provided. It looks promising. I'll take any sign of hope I can get.
Just tried the recommended procedure but no luck. It is possible that I screwed up steps 7 + 8 because they were not clear to me.

Copy the nv_data file from the SD card to the newly generated EFS folder on the phone and name it nv_data.bin. Then make another copy in the same EFS folder and name it nv_data.bin.bak.
Then you need to set the permissions for EFS folder/nv_data.bin file. They need to be set to rw-r-r. However for this procedure you need to be rooted.

Could you tell me did it work?
No, unfortunately it did not work. After following all the steps again, the IMEI still comes up incorrect. The search continues ..........

Have you tried flashing the stock firmware again? Either by smart switch or odin?
Will try again tonight when I get home.
Callumbr1, No dice on the stock flash. I installed Smart Switch and tried to do the reinitialization. It gets along in the process and then fails in the " Device does not have DRK" error. Also have DM-verity error. I tried to find solution briefly but didn't get far. Ran out of time tonight. Will try again tomorrow. Still appreciate your help.

I remember I did have the exact DRK error on my s6 edge one and dm verity fail. The way I fixed it was by flashing stock firmware through Odin. Quote me when you try again and I'll do my best to help mate.
IMEI
If you want to get back your IMEI try Dashboard .
you will find all your devices there, then try to find a way to write your IMEI in your phone (may need root)

Currently I had damage a new phone in the process of transferring a twrp backup from my gold note 8 onto my black note 8, but now silly of me I didn't realize I tried restoring the efs partition as well causing me to have a bad partition. Now, I currently manage to fix the efs partition and solve some issues im just stuck in trying to find the file in which I can alter the IMEI as currently its 00000000000 i've checked NV_data, but I cant seem to find the offset that contains it i've tried searching it on my working phone to see if I can spot the imei so I can find the right offset, but no dice.
edit: I've solved my problem i'm not sure if it'll work for you, but what I did was root my device, delete the efs folder which eventually game "000000000" imei and the baseband wasn't appearing as unknown anymore, then within the new efs folder that was created on its own there was a folder called efsec in which it contained !svc and svc files, so I extracted these files and edit these files with notepad++ which within there was an option for imei and it showed me all 0000000 so I imputed the original imei, and finally after a reboot I reflashed stock and then flashed a combination file which when it booted up it automatically restored my imei

Thanks for the answer. I would like to clarify one point ...
I realized that you replaced the parameter "deviceID": "00000000000" in SVC and !SVC files (in the newly created /efs/ sec_efs folder) with your original IMEI.
But what does "and then flashed a combination file" mean?
With which software did you flashed the modified SVC and !SVC files?
Maybe you just replaced SVC and !SVC files with 00000000000 IMEI onto SVC and !SVC with your original IMEI via RootExplorer for ex.?
