[ATTENTION] Before Changes In Rom With Odin, Kies (Update Firmware) Or Flashing Save Your EFS Folder
Its Always Better To Save Your EFS Folder, Just To Be SAFE...
Why?
If You Lose Your IMEI # You Can't Download Apps Through Market Or Etc. In Turn Making You Spend Money At A Samsung Repair Center...
What If I Already Odined, Used Kies (Update Firmware) Or Flashed A Rom?
As Long As Your IMEI # In Settings And The One Under The Battery Match Your Fine...
How Do I Get My IMEI # Back If It Ever Changes?
As Long As Your Device Is Rooted Replace Backup With Root Explorer Or Use The App To Repair...
Must Be Rooted And Have Busybox...

Remember Its Really Important...
App Thanks To Lyriquidperfection...
I Dunno If T-Mobile GS II Needs To Do This But Its Always Better To Be Safe...

Hey I Got An Alternative Use Root Explorer Go To Root Find EFS And Press And Hold It When Menu Pops Up Press Copy, Go To SD Card And Press Paste... There Should Be A Copy Of It Now On The SD Card Plus The Original....
Edit:
I Found That Its Exactally The Same As The Tar From The Tool I Refered Everyone To, All The Files Match Up...
Also If You Look In Etc/Firmware/Misc_mdm/Image You Find 3 EFS MBN Files, I Didn't See Anything In FS... So Im Guessing Its In The Rest Is In Firmware...
Still no update on where the nv-data.bin or nv-data.bak files are, huh? The i9100 has them in the efs folder but still cannot locate them for t989.
I'm having these same issues with an unknown IMEI, IMEI SV, and baseband.
Hi all:
I got a new galaxy nexus that i'd like to use as my main phone, but I don't want to go through the trouble of setting it up again, my current gnex is just perfectly setup. They both have the same version of android (4.0.4).
I was going to to a clockwork mod backup of the current phone, move it to the new phone and restore there, but I think I'll mess up the IMEI if I do that?
What additional steps do I need to carry out to preserve the phone's IMEI?
Thanks in advance.

If both have absolutely the same ROM, restore just the data backup, not the system backup, and you should be fine.
You can copy the IMEI on the original nexus to the other? Wouldnt that be best?
Is so follow these steps (it may look much, but i dont think it would take long if u want to keep your original imei number!
You must have:
-Root
-Root explorer for copying files to and from EFS folder
-Android SDK for the ADB tools or Terminal in your phone.
IMEI is stored in ".nv_data" file in ORIGINAL SHIPPED EFS folder too, so you just have to do these:
1) make a copy of your EFS folder to your sdcard using root explorer and then make a backup of the folder to your computer [ to have another copy if you had to format sd card sometime ]
2) delete the EFS folder (BE SURE YOU HAVE BACKED IT UP IN A SAFE PLACE AS SAID IN STEP 1) from the root of your phone using root explorer.
3) reset the phone, after that, go to the root, and you can see that the EFS folder is still there, don't make any mistake, this EFS folder is new and generated by the android OS.
4) go to EFS folder using root explorer, and delete "nv_data.bin", "nv_data.bin.md5".
5) go to your backed up EFS folder on your sdcard, copy the "imei" folder to the EFS folder at the root of your phone, then again go to the backed up EFS folder at yout sdcard and copy the " .nv_data " file to your EFS folder at the root of your phone using root explorer, NOTE: the dot in first of nv_data is not a mistake, copy the ".nv_data" file.
6) make another copy of the ".nv_data" file in EFS folder in your phone, so you would have 2 copies of ".nv_data" in EFS folder
7) rename one of ".nv_data" files to "nv_data.bin" and another one to "nv_data.bin.bak"
8) at your PC open CMD at the ADB tool path, or run Terminal at your phone enter these commands:
adb shell ( use this command of you use ADB, if you're using terminal, skip this line )
su ( ALLOW THE MESSAGE CAME AT YOUR PHONE's DISPLAY BY SUPERUSER PROGRAM )
chown 1001:radio /efs/nv_data.bin
9) reset your phone.... after that you have your original IMEI. you can check your IMEI by dialing *#06#.

Thanks for the suggestion. Unfortunately, it doesn't seem to work, my IMEI gets clobbered to some generic IMEI when I do this.
Off to trying try sikiduck's suggestion.

Stupid question... there is no efs folder. Do you mean /factory? There are nv_data files in /data/radio as well.
I'll play with these a bit and see.
You got root?

Yes, I do. I tried playing with the nv_data files, but I can't get the original IMEI to come back no matter what I do.
Does someone knows is there EFS folder on LG G3 because I cant find it with RootExplorer. I was looking on SdCard and through whole device but theres no trace of it. I've made a backup with adbshell comands and got modemst1.img and modemst2.img but I want to copy and save EFS manually.

It's not manual but there is an app called efs backup that backs both the efs file and the modem for you

thank you very much!!!
Like the title says,
Where is EFS folder so I can delete it? I want to delete it so that when I reboot it it would create a new one? I think mine is corrupt.
Thanks in advance.
