[Galaxy S III Q&A, Help & Troubleshooting] tomniu:
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?

Thank you

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.

Restore IMEI on SGS2: http://xdaforums.com/showthread.php?t=1264021

Download EFS PRO: http://xdaforums.com/showthread.php?t=1308546

Download your original firmware using check fus downloader (http://xdaforums.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 :)

IMEI restore on SGS 3 (GT-i9300)

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 :)

---------- Post added at 12:16 PM ---------- Previous post was at 12:10 PM ----------

Good news is that it will work - even if you did not back up your efs folder before you messed with it!

I did backup after the phone was rooted and new rom installed. Too late the IMEI was gone. I posted the problem on this site and was helped by DocHoliday77. he gave me some simple instructions and 2 files to download. I followed the steps and presto I was back in business. there are files to restore the IMEI and to get the data connection back. I did this a few days ago and it worked. The best part is that the phone does not need to be rooted. Please credit DocHoliday77 for this. This site is pretty cool.

I had a similar problem with my SGS3 i9300. I backuped the efs in aroma installer and then flashed omega rom, lost my IMEI (it changed to 004999...), could not connect to my network etc. I restored the IMEI by unraring the efs_29Sep2013-2102.tar.gz to my external sdcard (I got te efs folder). Then I pressed delete on efs folder located in root using root explorer (te efs folder stayed but everything inside it was deleted). Next I copyed the contents of my unrared efs folder from external sdcard to the efs folder in root. I didn't change any permissions, just restarted my phone and IMEI came back and everything worked for me.

To see ALL the files in the EFS folder you need should use ES File Explorer and make sure the 'show hidden files' tab is set to ON. All the files will then will be shown and you can follow the 9 step procedure.

If you don't do the above you'll be able to follow some of the steps but when you delete the EFS folder it will say deleted but a) the folder will still exist and b) the folder will appear to be "empty" which it isn't.

1-restore your phone to android 4.1.2 official stock rom (UNROOT): http://xdaforums.com/galaxy-s3/general/fix-s3-to-factory-unroot-stock-recovery-t2323847

2-after that fully charge your mobile phone to 100% (really needed not just for fun)

3-open KIES from samsung and connect your phone using you cable.

4-from tools--->Software upgrade and initialization-->proceed for that step till it ends following the instructions from kies.

5-it will download about 1.2 GB of data ensure your internet speed is fine.

6-make sure you have enough space on your computer about 5 GB

7-after it finishes in kies you will have your phone good as new with android 4.3
