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

Yeah my IMEI is "004999010640000". So I'm going to check for the efs back up. I'll report back.

There wasn't an efs folder in the root to copy over. But I did go ahead and copy the efs folder that was inside of the backup folder to the root and rebooted and my IMEI is still "004999010640000"

Oh did you copy it into the root of the sd card? Because I meant the root of the device.

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?

Okay, sort by date and find the oldest one and then go and delete the contents of your root /efs folder and copy the files from the oldest efs backup into the root /efs folder then reboot and check.

What files do you see in the efs backup and what app are you using to move them?

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.

I donated to you. Thanks for helping.
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.

Forgot to have nandroid backup . Wiped data, cache partition, dalvik cache, battery stats Couple of times. Screwed up the phone for flashing, No signal.. Later, I was able to fix it with SGSII_repair But, stuck with a generic IMEI (004999010640000). I haven't backed up efs folder. Now I'm only left with cryptprop_es in the previous efs folder.. Is there any way to restore original IMEI ???

Try this ! 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#.
If all the above steps do not work, check with a called developer Odia on XDA, he has recovered many phones with lost EFS.
All the best.Hope this helps!

I don't have the nv_data files or, anything related to that !!!
Have you tried GSII_Repair from the Market ? This might be your last best chance before you need to send it to Samsung/your telco for repair. Look for it, read the description & then decide whether you want to try it or not.
If this doesn't work, nothing else will.
Edit to add - My bad.

Yeah !. This is the App Which Has Set The Generic IMEI & Brought Back The Phone's Signal !!! Would it Be A Problem in Future if, I Stick With This Generic IMEI ??? (I Know That Some Operator Blocks This IMEI But, Mine Didn't, Yet..)

He says in the opening post he has tried GSII_Repair which gave him the generic IMEI.
OP, if your EFS folder is empty and you made no previous backups I suspect you will have to send it for repair.
Imei is known by telephone company?
Can't he just get imei from them and create new folder if there is no backup?
Isn't imei on phone box?
Sent from my HTC Glacier using XDA App
The necessary files are encrypted. Even if he knows the IMEI it's not just a simple case of creating a text file with it in for example. I wouldn't be surprised if his MAC address has gone too.
Do a search for the post about user ODIA who has helped some with no IMEI .

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?
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!

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.

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.

I have only two back up files: efs.img and efs.tar.gz, but efs folder should contain much more files.
I delete efs folder in the root and restart phone, but anfter restart it only creates the efs folder which is empty.

Ok so click on efs.tar.gz and there should be the efs file. Copy that and and place into efs file at the root of your phone. Click on 'yes' when it asks if you would like to overwrite the file

I have done this, but after reboot all these files are deleted and efs folder remains empty.

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?
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

Unzip it with a file manager and use a root explorer to replace manually

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

Read the imei / efs thread in general.

i am stuck

- my efs(folder) is blank

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.

i have both efs.tar.gz and extracted folder ready in my ext-sd......
i wonder if somebody can help me with creating a cwm.zip from the .tar file
thanks ....
try to install stock again via odin but this time install a diffrent version (for example if you installed INU this time try INS).. before that factory reset your phone and wipe cache via recovery mode.. don't lose your efs backup it's very important copy it to your PC in case something wrong happens
i already did so

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"
