Because it needs to be renamed as xxxx.tar

That's a CWM flashable zip. EFS is also mmcblk0p3 on the s3 so the script will also work for you.
Whaha sometimes there are very stupid people around here.
He doesn't even know what he is doing by posting his EFS here.
Never saw something stupid......

Guys,
I'm totally stuck, so i'm begging for your help...
can someone please make me either an update.zip or a flashable odin .tar that will flash the following files to the /efs folder...
i'm trying to fix my phone and restore its signal and for the life of me i cant get /efs to mount as rw for me to manually change the files via root explorer or adb... it appears to become r/w, but then suddenly reverts and the changes disappear....
the zip includes 2 files, .nv_data.bak and .nv_data.bak.md5, they need to be flashed to /efs along with copies renamed to nv_data.bin and nv_data.bin.md5 respectively... so 4 files will get flashed to /efs
any help would be appreciated massively
Cheers
Dickie
EDIT: attempted an update.zip, receiving a status 6 error... giving up for today, being trying to fix this for 18hours now... if someone could look at this for me it'd be appreciated...

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.
I have asked him again to post it in this thread
Is there any way to extract that .img file???

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.
My s3 stopped recognizing the Sim yesterday, so i searched for a solution. i read in xda that its the EFS partition. I got no IMEI and no Baseband. Somehow i found 2 files on the internal SD Card: "efsbackup.tar" and "efsdev-mmcblk0p3.img".
I read this thread, but it didnt help me.
Any idea how i could fix it?
Btw, Android Revolution HD 11.0 with stock kernel
I'm guessing your Rom auto backs up the efs, so best to ask on their thread about reinstalling it
Restore your EFS backup .
jje
im going to install now arhd 11.3 and then do the restore of the efs backup.
i noticed that the backup was built yesterday evening, when the problem already was. well it seems like i got no backup, when it was working
I followed in this thread this post:
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

and now i got an IMEI, but its still not mine: 004999010640000 / 01
If you have an efs.tar file why dont you put it in PDA in Odin?.
wont work.
deleted
Ok....then I dont understand why it backs up as a tar file then
yesterday i flashed siyah kernel, siyah probably made a efs backup. but that backup was already after that problem happened.
well i got now the 0049 imei
So you dont have a back up of you original IMEI is that what your saying?.Flashing ROMs normally is what makes a backup not flashing a kernel so Id say the backup is original.

you need to read better then
You'll need to perform an "IMEI injection" which is a kludgy last-resort restore method that manually writes the IMEI to NVRAM; the link I provided in Part C of "Backup" will tell you how to do it.

That's what the efs backup is for xD
Calm down, or you'll make things worse. Unzip the efs.tar to /efs and reboot your phone (DON'T PULL THE BATTERY)
Everything should work like a charm again
Hope I could help!

well, thats how my phone ended. i did that yesterday and my phone finally didnt even booted.
then i went to my carriers shop and told them it wont boot, and today i got a brand new phone
anyway thanks to all help!
Problem solved!
**********************
I think my problem happened because a flashed a ROM with MG4 baseband, and then flashed UltimaROM with another baseband which caused my baneband to corrupt.
I tried to flash Stock ROM and install different baseband but non of this worked.
finally I flashed BTU stock ROM (Which comes with MG4) but the problem still here.
Then I installed root, deleted the efs folder and replaced all the files with the files in the backup - restart and everything is working! my IMEI returned to normal.

Original question
Hello devs,
I have Siyah kernel which auto backup my EFS, i have backup named "efs_28Aug2013-1852.tar.gz"
I want to restore from this backup because I lost my IMEI when I flashed UltimaROM
I renamed it to "efsbackup.tar.gz" and put it in the root of the sdcard
then I started adb shell & run the code
Code:
su
umount /efs
mke2fs /dev/block/mmcblk0p1
mount -w -t ext4 /dev/block/mmcblk0p1 /efs
busybox tar zxvf /sdcard/ efsbackup.tar.gz -C /
I granted ADB shell root access
then i went to recovery and run the command (because I can't run umount /efs while device's running it gives resource busy message)
However when I run the first command "su" in gives me this message
Code:
/sbin/sh: su: not found
so I skipped to the next command
but I get the message
Code:
umount: can't umount /efs: Invalid argument
Please guys any help appreciated

I've backup my efs with adb but how do you have a file on tar format, i've got a file on .img, it's normal ?
There's about nine different ways to backup the efs, .img is fine but a little on the large side at 20mb. A .tar of the same is only 5mb.

Thank you for your reply, I did as you said but this only changed my IMEI from "Unknown" to the generic IMEI "004999..."
Is there something wrong in the method or my backup may be corrupt

i have efs.tar.gz file and a folder named efs in my ext sd
how do i copy that to int memory?
can't even create a cwm flashable zip file of the same?????
help me bro.....
You are posting in a thread that tells you how to restore an efs backup, how much more could you possibly need?
Go to recovery, factory reset.
Get the phone to boot, unpack the .tar file and follow the instructions in the OP.

bro, thanks for your help recently i tried cm 10 also but nothing happened.
believe me i tried everything now the only option is left that is
to restore efs backup from efs.tar.gz (which is about 12 MB)
OR
create a cwm flashable zip from the efs folder which is about 22 MB)
OR
take my phone to download mode and try to push whole "efs" folder to the location with help of "ADB"

As far as i can tell your EFS Backup is Corrupted or u have lost your efs backup.
here is what you can do. try to locate efs.tar folder in your internal memory or SD card see if it is there,
secondly you can Google for restoration of EFS. this Should Resolve your Problem

it should either be a folder efsbackup or a zipped/tarred file at the bottom of the directory, usually on the internal storage.

Hi
Have you tried the S2 Repair it worked for me first time ! I had blank IMEI and baseband unknown used the S2 Repair app and it worked a treat.
However when i did a kies update and software update on my phone it went back to blank and unknown and now the S2 Repair app doesnt work.
But just use the S2 Repair and it just might work and its easy to do !
I was thinking of reflashing mine and hope it works but i think my problem is with the efs folders

Hi
I have exact same problem Blank IMEI and baseband unknown.
I have just flashed GT-I9100_XEU_I9100XWKI4_I9100XEUKH2_I9100XXKI1 and still the same except lost root.
I Then flashed insecure kernel CF-Root-SGS2_XW_NEE_KI4-42-v4.2-CWM4 then secure CF-Root-SGS2_XW_NEE_KI4-v4.1-CWM4 and now have root back BUT still blank IMEI and baseband unknown
I have got a efs.tar.gz file in the internal sd card ? i think it came from a efs back up from when i used galaxy s unlock app
I also have efs_save.tar and efs_save.tar.gz in a folder named GSII repair but i am guessing these might be back ups of corrupted efs folder ??
The imei file in the root efs folder has a mps_code.dat file dated dec 25 2013
but in a back up efs folder in GalaxyS2Unlock it has the mps_code.dat file dated nov 29 2013
NOT SURE WHAT TO DO ?:crying:
