Hi, everyone!
I need advice of an experienced person.
The efs folder on my device Galaxy Tab s 8.4 (SC-03g) is empty (Tab is rooted). It had happened after custom firmware upgrade.
I have a backup of efs (it is not a tar file or something. I have made a copy of efs via root explorer. It is on my sd card).
When I try to copy it back on device, it copys well. But after device reboot the root folder EFS became empty
Maybe it becouse of wrong premissions, but I dont know, what permissions are correct.
Can anyone help me with this issue.

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.
Hey guys,
I have used gnexus toolkit 'Boot to CWM Recovery without Permanently Flashing it' to start my gnexus, and made a nandroid backup, but i can't find the backup files in my clockwormod folder. When i Boot to CWM Recovery, there is a backup files in restore option, then where is the backup files?
Anyone can help me? I want to find the backup files.
Thanks.
At least in my Galaxy S2, the backups are kept in the microSD external_sd card, folder clockworkmod, subfolder backup
From this external microSD card, CWM is able to recognize every single backup I saved for restore..
post is right above me.
it is located in:
sdcard/clockworkmod/backup or
data/media/clockworkmod/backup
They should be recognized in recovery (under backup and restore option)
Are you browsing using an Android file manager or plugging the phone into a PC? I had a simular issue where CW backups weren't showing when connected to my computer, although they were there using ES File Explorer.
For me, they eventually appeared in "sdcard/clockwork/backup" while browsing the file system from my computer.
my problem

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.
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
