Hi,
I'm using GT-I9300, and now I lost the IMEI. It is showing 00499010640000 / 01
I have a backup of efs folder copied using esfile explorer, dont know is it a full backup or not. Tried to copy paste back but doesnt help. Flashed different stock ROMs single file and 3 part file with pit + re-partition but those methods deosnt help me.
Some one please advice...

You can restore the efs file with kTool by Hellcat, it`is in the Playstore. First place your backedup efs file in /sdcard/efs.image and then restore. Haven`t done it myself yet, and you better google it or wait for other advices by people who actualy did it. Good luck

I haven`t restored my efs ever, so i`am not 100 % sure it will work. The esfile explorer file should be an .img file i think. Betterwait for someone who knows more about this stuff. Don`t you have a working backup in cwm that you can restore and have your imei number back?

Using es file explorer or root explorer mount system as rw and delete the current efs folder. Then copy / past the copy you saved and reboot. Original imei will show again.

Did you first delete the current efs folder? Maybe try again and delete the factory folder as well and confirm the remaining efs folder has nothing in it. Then past the copy efs folder and reboot. If that doesn't work then possible you don't have a full copy.
My backup of those 2 folders have have 19 items in each when viewing in My Files. How many does yours have?

What format does you backuped efs file have, tar or zip or something else.
It's easiest to do it in Recovery mode, make sure /efs and sdcard are mounted in Mounts&Storage.
Connect to the phone over ADB, then copy the contents of the backed up folder to /efs and restore permissions
Code:
cp /sdcard/YOUR/EFS/Folder/* /efs/
chown -R radio:radio /efs/
chmod -R 755 /efs
Then reboot the phone, hopefully it will work. If not, please attach the logfile from the /efs folder to the post so we can see what goes wrong.

Log file from efs?

I have included a script in a initd script segment to create a file called efs.autobackup.img
The forum is filled withon how to creating the .img file but i couldnt find about how to restore.Ktool doesnt work on this.
I am asking this in behalf of a fellow xda member.He got a factory efs files in some old Indian firmware, flashed it by using clear phone efs in odin and now he has some generic IMEI.How to extract the files inside the .img file atleast??
Atleast he can use the files to change his IMEI using nv_data.bin and nv_data.bin.md5
If it's a raw .img (20MB in size) kTool should work fine.
Just rename the file to "efs.img" and put it to /sdcard (root of the internal storage when mounted to the PC).
Then run a restore via kTool (be sure to use latest version).

If the .img is OK and not already of a broken EFS, or the image itself is corrupted (all these things can happen, sadly) then it can surely be restored.

He is saying that restoring with efs.img makes his phone go to unknown baseband and IMEI.

In a shell, type:
Code:
su
mkdir /sdcard/mnt
mount -t ext4 /sdcard/efs.img /sdcard/mnt
Then use your fav. filemanager to go to "mnt" on the internal storage.
If the mount command gives you an error, it's likely the .img is corrupted.
Hello,
I'm trying to get back to working 911. I've used Odin to flash all the way back to stock Eclair, yet when I dial 911 it just hangs right up without connecting. I flashed Froyo and the same thing. I thought all I needed to do was flash back to an earlier rom? Can someone point me in the right direction?
If it doesn't work on stock, it's probably a busted efs.
1) Go in About Phone > Status and check if your IMEI is "004999010640000"
2) You'll want to restore your efs. Check your sd card for a folder called "backup" and a folder inside that called "efs", copy that the "efs" folder into root, replacing the efs folder there, then reboot. You'll want root for that. Then go in and check that your IMEI is not 004999010640000

I accidentally copied to the root of sd and then noticed you meant the root of the device. So I went ahead and copied to the root of the device and restarted and still have the same fake imei number. I even tried the "Recover your imei in 9 steps" tutorial and no luck. Now I'm using EFS Pro to see if I can restore or repair or something. Ugh. I just moved into my own apartment (I used to live with a male roommate) and seeing as though I am a female living alone now, I really need 911 in case of an emergency. I'm considering just buying a new phone I'm so frustrated. When I attempt to scan with EFS Pro it says "no backup to restore" even though there is a back up.
Are there multiple efs folders in the backup folder on your sd card?

I'm using root explorer to copy and paste the files and I see the following 14 files in the backup:
.imei
.nv2.bak
.nv2.bak.md5
.nv.data.bak
.nv.data.bak.md5
.nv_state
cryptprop_applied_result
cryptprop_data
cryptprop_onetimeboo
tcryptprop_securewipedata
imei
nv.log
nv_data.bin
nv_data.bin.md5
I'm not sure if they're pasting correctly though. It says "merging" but shows today's date for the files instead of the Dec 2011 date that shows in the backup.
I renamed the .bak files to regular ones to see if that will restore the backups, the copied them to the root efs. rebooting now.
Okay try this, download a terminal emulator or use an adb shell and run these commands:
Code:
su
rm -r /efs/*
cp -r /mnt/sdcard/backup/efs-NNN /efs
Replacing NNN with the backup from December 2011.
Then close it and reboot.

When I try to run the command it says "cannot create" because there is no more space on device. Which is weird because I dont really have anything on here.
I did double check the time from the backup that copied to the root efs and it did update so the files were copied. Same fake imei though. I'm guessing all of the backups on my phone are of the fake imei because I got the phone in June 2010 and was flashing roms within two months, yet the earliest backup is December 2011. I vaguely remember upgrading my SD Card with one that had more space. So the original imei back up is probably long gone on my old SD Card. Is there any hope for restoring my imei and getting 911 or should I just get a new phone?

I'm back to the fake imei and now have tmobile connection. I tried http://forum.xda-developers.com/showthread.php?t=1264021 guide with no luck. It just puts me to an "unknown imei" with no network connection. So I have to delete the efs folder and hard reset to get back to the fake imei. I also tried to install HC-ktool IMEI Recovery app and it says "problem parsing package" and won't install the app. I'm guessing it's not compatible with Stock Eclair. Im going to try upgrading to froyo and try to get the HC-ktool IMEI recovery working. If all else fails I'm honestly just going to go buy a new phone today. Ive had this since it came out June 2010 which was over 2 years ago so maybe this is a reason to upgrade to the Galaxy S II or III.

After hours of trying to get my imei back I just decided to try a rom that was known to have working 911 since that's all im after any way. I went with stock Gingerbread and 911 is working. I still have the generic imei but all I wanted was 911 so I'm all good.
This is important I think we should figure out a way asap

nv_data.bin not in efs folder
Hi guys,
I used Total Commander to copy my /efs directory to a backup folder within the internal sd card, so it is likely that all file permissions are retained in the efs backup. However, I did notice that my /efs directory did not contain nv_data.bin, even though my IMEI is intact. Can anyone also check whether you have nv_data.bin inside your /efs please?
No i dont have that file in that directory......Prodigiez way is excellent a nice neat Img file has been created with all the efs valuable info/data..... My Rom Is now De-Bloated, Zip_aigned/Deodexed, Rooted, Unbranded and Nandroided thanks to all these devs and my motivation

Maybe its just me but I prefer the old style copy and paste method. Using root explorer or similar I simply copy the efs and factory folders and save in multiple places (external sd, PC etc).

Not a good idea as you're also losing the permission bits (I take it your external SD is a variety of the FAT file system and your PC NTFS). For example, nv_data.bin has a mode of 0700 and is owned by radio:radio. Say your /efs folder gets wiped and you then copy back your efs folder from your backup. The file (since the umask seems to be 077) will now have the mode as 0600 and be owned by root (because you'd be using Root Explorer/Terminal Emulator to copy back the files which runs as root and not radio). Whatever process (presumably running under the user radio) that looks at that file now may not be able to do so now it's owned by root.
With a tar backup, you're still preserving the permissions which are just as important as the files themselves (though you could look at another GS3 to figure out the correct permissions, granted). With a backup to an image using dd, well, it's the raw partition so I imagine everything on /efs gets backed up.

I've used the copy / paste method on S1, S2 and S3 and copying the folders / files back manually with root explorer works all the time. Haven't had any issues with permissions.
I test by purposely corrupting my imei (yes I'm crazy) and copying the backup back and all is good. Mind you I also have the auto generated tar backup as well but still prefer the copy / paste method.

Fair enough, I'd just rather restore from a tar backup since I believe there's a reason why nv_data.bin for example is owned by radio, but good to know it works.

Well I just checked 2 phones:
S1: I have previously restored the efs folder via copy / paste and the current owner is 'system'.
S3: It's my second S3. Unlike my first unit I haven't repasted the efs folder. Owner is 'radio'.
Conclusion is that you are correct about permissions not copying over correctly with the copy / paste method. It's an easy fix via root explorer to change if required, but not ideal especially for noobs.
Fortunately the change in owner didn't cause any issues but still probably best to use the tar method as you suggest just in case.
Thanks for the info.

Well, obviously, you copy the contents of the efs partition
Code:

and zip it into a tar ball.
Then you put it safely onto your dropbox and voilà.

but I dont remember backing them up
Hello, i have used ktool to restore my imei, but it ereased all my efs folder files, so now it is empty. I have made my imei backup using ktool app, so i have efs.img and efs.tar.gz files.
I have tried to flash stock rom with odin but not only one of them boots, they all get bootloop. My phone only works with cm9 but it has no imei and no network.
So i need these files from efs folder, could any one help with this? Or is it possible to restore them with my back up files?

A simple copy and paste worked for me using root explorer.
If you have efs back ups:
Delete entire efs file on the root of you phone and reboot. Upon reboot a new efs file will automatically be created.
Copy the efs file back up and place into the newly created efs file at the root of your phone. Reboot into recovery and wipe cache.
This method restored a corrupted efs file on my s3.

Ktool must of made a back up an empty folder. Don't know what to tell you. Do you have any files in storage called efs_backup? I think some recoveries or kernels automatically back up the efs file when doing a nandroid. Find the earliest back up and copy and paste.

The back up is made correctly, i open .tar file and there are all these files, but when i copy them into the efs folder in root and reboot phone, these copied files are just gone.

I read on some other efs problem threads that flashing some newer firmware (ending with mg4 or something like that) reformats the efs file and you have to flash different firmware in order to fix from back ups. Look into other threads, they might have the proper procedures to fixing efs.

Trying to flash firmwares and roms with these endings, but the phone doesnt boot, just stucks on samsung logo and repeats animation. It might be because i was installed leaked 4.2.2 xxufme7 firmware so it cant downgrade to 4.1.2 firmware.

Just a thought are you doing a factory reset between flashes also doing a factory reset with stock recovery will wipe your entire internal sd
Have a look at EFS Pro to restore a tar .

This might be my misstake.
By the way, this is solved already. I flashes stock 4.0.4 version and used ktool to restore .img and .tar files, after reboot network came back and all efs folder files were also back, then flashed atock MG6 So now i am on this stock firmware.
But i still cant install leaked version FMU7, it gives me fake IMEI and no network, any ideas?
Flew ESF folder. Help restore.
Thanks!
try through CWM Recovery (Wipe data/factory reset)

First of all, do u have any backup of efs? If yes then try to restore it and if not then try the following methods.
Flash latest stock firmware.
Root ur device.
Install x-plore or any root file browser.
Go to root directory and open /efs folder.
Open /efs/FactoryApp/keystr and edit and write 'ON'
Open /efs/FactoryApp/factorymode and edit it and write 'ON'
Change permission of both file to 744 mode and restart ur device. It may help u to get ur phone working. Try it now.

The permissions for the folder and each files are different. Some files has permissions 744 and some files has 755 and the permissions of efs folder is 711

Could you elaborate. Take a screenshot folder "EFS" in the resolution and in the folder contents show what should set the resolution?
