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.
HI, i got this problem since i update to 4.2 (or i notice just after update) :
i made one nandroid backup in 4.1.2 and 2 backup in 4.2, but when i enter in clockworkmod/backup i can see only the files from old 4.1.2 backup.
New backup really exist because i can restore it from recovery! but no way to see the files or directory under /sdcard/clockworkmod/backup ...what is the problem? to browse folders i use root explorer, and also in windows7, but i always see only the old backup directory i made on 4.1.2... now deleted it, but no changes, now the backup folder is empty...
any ideas/solution?
thanks!

/sdcard is a symlink the files are actually stored at /data/media/0. The new CWM bacups should be at /data/media/clockworkmod/backup
I use root explorer for efs folder backup. Any other suggestions that are compatible with grand?
Problem with root explorer if you do not know how to set permissions then restoring will not work.

Try using ES File Explorer, on the settings panel, select root explorer > mount r/w > select rw for both / & /system.
But why do you need to backup the EFS folder? Your IMEI won't get lost if you are using Custom Kernel or anything. In case if you want to restore to your region's CSC code, view my topic here.
There us always a danger that you will accidentaly wipe the efs folder when flashing. This efs folder backup is highly emphacised here in xda and elsewhere. It is very difficult to get back the imei in case it gets erased. So I put up the question here. I also learned that it is even illegal to change the imei in India.

hello, to recover the EFS folder on your device before flashing, you should make a backup in case something goes wrong. By I have heard of a method for a generic IMEI but do not know if it works in tab 3
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
