Hello XDA Users,
I think some people here know who I am, so I will jump on the "Introduction of myself" for now.
Recently, I have faced many questions & problem of fake IMEI, of damaged EFS folder. So I made a little experiment on my device(GN2).
First, I backuped my EFS folder in 2 types - one is .img and the second is tar.gz.
Then, I deleted my EFS folder using ES Root Explorer. Which made my device to be on somethine called "Permanent Safe Mode" - You can not get out untill you fix your EFS folder and change some values.
This is permanent safe mode:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After I did my "research" I have managed to make several methods to backup & restore EFS, which should make your life easier and better.
First of all, Disclaimer:
I'm not responsible for any damage caused by using these methods, all methods tested by me, so it should work on your device too.
This is for I9500 Only!!!!!!!
Let's continue.
What you must have:
Latest base with latest modem and latest kernel - very important since in the latest versions samsung prevented the option to install old modems/kernels, so if you install old kernell/modem it can show you wrong IMEI.
Rooted device with the latest Super User
Latest busybox
CWM / PhilZ Recovery
Terminal Emulator
Root explorer - Can be ES File Explorer with working root option or just a root explorer from the market
A working EFS backup(In order to restore it...)
Time & Patient.
Important Notes:
When installing XWUBMG5, several people suffered from Fake IMEI. This is because the new firmware messed up your EFS folder, which means that you can not restore EFS backup until you are on older version, recommended is XXUBMG9(right to 05/08/2013)
Some custom roms include modem installation in their rom installer. Due to modem flashing in recovery, some devices might get Fake IMEI. My recommendation is before even starting to use this guide, please try to install the latest modem via odin from this thread:
http://forum.xda-developers.com/showthread.php?t=2192025
You will find at least one method that works on your device, so don't give up after one method.
Note II & S4 has the same EFS partition (mmcblk0p3), All methods were checked by me on my Note II and fully work. So it should work on S4 too. At least 90% of them
Read all guide and pay attention to all small details.
Backup methods
Method 1 - .img backup
First method, is an automatic backup/restore software.

Method number 2 will create you efs.img backup on your internal sd. After that you can copy it to your computer.
What you have to do is this:
Open terminal emulator
Write the following:
Code:
su
Then click enter. It will ask for super user permission, give it permissions.
Then write:
Code:
dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img bs=4096
Then click enter.
When it finishes, check if you have efs.img on your phone memory. If so, copy it to comupter, if not, you did something wrong try again.
Click to expand...
Click to collapse
Method 3 - .tar.gz backup
This method will compress your efs folder into tar.gz file. This method is the same as choosing backup EFS folder in my rom(PhoeniX ROM)/Omega/Wanam/etc.
A tar.gz backup should look like this(On some devices there might be more files, but this picture was taken from Note II N7100 backup and it fully works):
What you have to do is this:
Download this and copy it to your device:
http://d-h.st/f4I
Reboot into recovery
Flash the zip
Reboot your device.
Connect your device to your pc, and copy the backup in "efs_backup" folder.
Click to expand...
Click to collapse
Restore methods
Now the fun begins
You will have to restore your backup when you have one or more of the folowing problem:
Fake IMEI (usually 004999010640000) or "null" IMEI
Blinking SIM card icon on the top tray… ETC
Unable to unlock your SIM card using your PIN
Fake Serial Number (usually 0000000) or "null" Serial
Unable to register to the network (usually comes with Fake IMEI & Fake Serial so check them.)
Attention please,
If you are 100% that your EFS folder is damaged and you have a working EFS backup with the right IMEI number, my recommendation is this:
With root explorer, go to your efs folder and delete all files inside
Long press on power button will turn off your device.
Then turn on the device, you will be in "Permanent Safe Mode".
Continue to one of the following methods.

Method 2 - Restore .img backup
Method number 2 will restore your efs.img backup from your internal sd.

Then write:
Code:
dd if=/sdcard/efs.img of=/dev/block/mmcblk0p3 bs=4096
Then click enter.
Now, reboot your device. If you still don't have IMEI/You are still in Safe Mod, reboot again.
In the second reboot, the bootanimation might stuck and the device will reboot automatically again. Don't worry, it is ok because it installs your efs.img.
Click to expand...
Click to collapse
Method 3 - restore .tar.gz backup
This method will restore .tar.gz backup.
A tar.gz backup should look like this(On some devices there might be more files, but this picture was taken from Note II N7100 backup and it fully works):
If you have like this, continue to the guide:
Create on your Phone Memory(Not Extrenal sd!!) a folder called "efsbackup"(without quotes)
Copy all files & folders from the EFS backup into "efsbackup" folder(The files are like in the picture)

Method 4 - restore .tar.gz backup
This method will restore .tar.gz backup.
A tar.gz backup should look like this(On some devices there might be more files, but this picture was taked from Note II N7100 backup and it fully works):

Copy all files & folders from the EFS backup into "efsbackup" folder(The files are like in the picture)
Using root explorer, go to "efsbackup folder, select all files & folders there, and click Copy.
Still in root explorer, go to "efs" folder of your device(It is located where all main folders like data, system, etc.).
In "efs" folder, click paste. It will ask you if you want to replace your files, select replace to all files(So all your files from "efsbackup" folder will be in "efs" folder)
Now open terminal emulator
Write the following:
Code:
su

Now write:
Code:

Hello,
It seems that crash backuped your Fake IMEI.
Something that I thing it might help, helped for some other, download latest modem from here:
http://forum.xda-developers.com/showthread.php?t=2192025
install it as a Phone in Odin.
it is importand to mark phone, and flash via odin.
Then try..
If you don't have any other backup, I think you might have to use your warranty.
When I backup the rom I forget my phone in flight mode maybe this the reason why I lost my imei ?
And my baseband now is
I9500DDUBMF8
+Edit
I found these in my internal storage
The First One From Crash Rom 5.0
And The Second From Stock MG5 Where I have fake imei

I don't think there is connection between these two.
Downlaod this:
http://d-h.st/esG
Open odin, Select Phone, select the modem's tar, connect phoen and flash.
After that check if you have IMEI.
If not, Try to install stock XXUBMG9 or XXUBMG5 - If you had MG5 before, it seems that you can not downgrade your phone, so try to install MG5.
If after MG5 there is still no IMEI,
Flash again as Phone via odin this modem:
http://d-h.st/Xxk
If still there is no IMEI, try to restore your current EFS backup.(Make sure you have Root and busybox and all I asked in the main thread)
If after that no IMEI,
Restore to stock and use warranty( make a story that you woke up one morning and you couldn't conect to your network, and you tried to mnake factory reset and still it didn't help)
Good luck

One question: is it device-specific (i9500) or can we use it on other Galaxy devices (I have i9305)?
I used this tool to backup the EFS and later on after flashing a custom ROM when i restored the backup i didn't get back to Service and the IMEI Was still NULL

Hello XDA Users,
I think some people here know who I am, so I will jump on the "Introduction of myself" for now.
Recently, I have faced many questions & problem of fake IMEI, of damaged EFS folder. So I made a little experiment on my device(GN2).
First, I backuped my EFS folder in 2 types - one is .img and the second is tar.gz.
Then, I deleted my EFS folder using ES Root Explorer. Which made my device to be on somethine called "Permanent Safe Mode" - You can not get out untill you fix your EFS folder and change some values.
This is permanent safe mode:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After I did my "research" I have managed to make several methods to backup & restore EFS, which should make your life easier and better.
First of all, Disclaimer:
I'm not responsible for any damage caused by using these methods, all methods tested by me, so it should work on your device too.
This is for I9505 Only!!!!!!!
Let's continue.
What you must have:
Latest base with latest modem and latest kernel - very important since in the latest versions samsung prevented the option to install old modems/kernels, so if you install old kernell/modem it can show you wrong IMEI.
Rooted device with the latest Super User
Latest busybox
PhilZ Recovery
Terminal Emulator
Root explorer - Can be ES File Explorer with working root option or just a root explorer from the market
A working EFS backup(In order to restore it...)
Time & Patient.
Important Notes:
When installing/downgrading firmwares, several people suffered from Fake IMEI. This is because the new firmware messed up your EFS folder, which means that you can not restore EFS backup until you are on the latest version, latest modem and latest stock kernel, recommended is XXUBMH1(right to 05/09/2013)
Some custom roms include modem installation in their rom installer. Due to modem flashing in recovery, some devices might get Fake IMEI. My recommendation is before even starting to use this guide, please try to install the latest modem via odin from this thread:
http://forum.xda-developers.com/showthread.php?t=2192025
When installing modem via odin, make sure you select PHONE and not PDA
You will find at least one method that works on your device, so don't give up after one method.
Read all guide and pay attention to all small details.
Backup methods
Method 1 - .img backup
First method, is an automatic backup/restore software.
Special thanks to A.S._id for his software.
The software:
I9505 EFS Backup / Restore
Help to preserve and restore the image of EFS partition:
* Need Root
For Windows
* Extract from the archive, connect the device to the USB debugging mode (System settings/Developer options/USB debugging) and run selected .bat (depending on the backup or restore)
* To retain the image of efs.img must be in a folder with Restore_EFS.bat
* Extract from the archive, connect the device to the USB debugging mode (System settings/Developer options/USB debugging) and run RUN_ME into terminal (double click), select option...

Method 2 - .img backup
Method number 2 will create you efs.img backup on your internal sd. After that you can copy it to your computer.

Method 3 - .tar.gz backup
This method will compress your efs folder into tar.gz file. This method is the same as choosing backup EFS folder in my rom(PhoeniX ROM)/Omega/Wanam/etc.
A tar.gz backup should look like this(On some devices there might be more files, but this picture was taken from Note II N7100 backup and it fully works):
What you have to do is this:
Download this and copy it to your device:
http://d-h.st/SaK
Reboot into recovery
Flash the zip
Reboot your device.
Connect your device to your pc, and copy the backup in "efs_backup" folder.

Restore methods
Now the fun begins
You will have to restore your backup when you have one or more of the folowing problem:
Fake IMEI (usually 004999010640000) or "null" IMEI
Blinking SIM card icon on the top tray… ETC
Unable to unlock your SIM card using your PIN
Fake Serial Number (usually 0000000) or "null" Serial
Unable to register to the network (usually comes with Fake IMEI & Fake Serial so check them.)
Attention please,
If you are 100% that your EFS folder is damaged and you have a working EFS backup with the right IMEI number, my recommendation is this:
With root explorer, go to your efs folder and delete all files inside
Long press on power button will turn off your device.
Then turn on the device, you will be in "Permanent Safe Mode".
Continue to one of the following methods.
Click to expand...
Click to collapse
Method 1 - restore .img backup
First method, is an automatic backup/restore software.
Special thanks to A.S._id for his software.
The software:
I9505 EFS Backup / Restore
Help to preserve and restore the image of EFS partition:
* Need Root
For Windows
* Extract from the archive, connect the device to the USB debugging mode (System settings/Developer options/USB debugging) and run selected .bat (depending on the backup or restore)
* To retain the image of efs.img must be in a folder with Restore_EFS.bat
* Extract from the archive, connect the device to the USB debugging mode (System settings/Developer options/USB debugging) and run RUN_ME into terminal (double click), select option...
What is EFS, Why it is necessary to backup
Click to expand...
Click to collapse
Method 2 - Restore .img backup
Method number 2 will restore your efs.img backup from your internal sd.
What you have to do is this:
Put your efs.img on your phone memory(not external sd card!) in the main memory, not inside folder.
Open terminal emulator
Write the following:
Code:
su
Then click enter. It will ask for super user permission, give it permissions.
Then write:
Code:
dd if=/sdcard/efs.img of=/dev/block/mmcblk0p10 bs=4096
Then click enter.
Now, reboot your device. If you still don't have IMEI/You are still in Safe Mod, reboot again.
In the second reboot, the bootanimation might stuck and the device will reboot automatically again. Don't worry, it is ok because it installs your efs.img.
Click to expand...
Click to collapse
Method 3 - restore .tar.gz backup
This method will restore .tar.gz backup.
A tar.gz backup should look like this(On some devices there might be more files, but this picture was taken from Note II N7100 backup and it fully works):
If you have like this, continue to the guide:
Create on your Phone Memory(Not Extrenal sd!!) a folder called "efsbackup"(without quotes)
Copy all files & folders from the EFS backup into "efsbackup" folder(The files are like in the picture)
Download this script & copy it to your device:
http://d-h.st/zwR
Reboot into recovery
Go to mount section and click on(Very important!):
Mount /efs
Click to expand...
Click to collapse
Now install the script you have downloaded.
After it finishes, reboot.
Now everything should be fixed, of course if your backup is 100% ok.
If it doesn't work, try method 4.
Click to expand...
Click to collapse
Method 4 - restore .tar.gz backup
This method will restore .tar.gz backup.
A tar.gz backup should look like this(On some devices there might be more files, but this picture was taked from Note II N7100 backup and it fully works):
If you have like this, continue to the guide:
Create on your Phone Memory(Not Extrenal sd!!) a folder called "efsbackup"(without quotes)
Copy all files & folders from the EFS backup into "efsbackup" folder(The files are like in the picture)
Using root explorer, go to "efsbackup folder, select all files & folders there, and click Copy.
Still in root explorer, go to "efs" folder of your device(It is located where all main folders like data, system, etc.).
In "efs" folder, click paste. It will ask you if you want to replace your files, select replace to all files(So all your files from "efsbackup" folder will be in "efs" folder)
Now open terminal emulator
Write the following:
Code:
su
Then click enter. It will ask for super user permission, give it permissions.
Now write:
Code:
busybox chown 1001:1001 /efs/nv_data.bin
Then click enter.
Now write:
Code:
busybox chmod 06755 /efs/nv_data.bin
Then click enter.
Reboot device. Now everything should work.
Click to expand...
Click to collapse
Exit "Permanent Safe Mode"
When you in "Permanent Safe Mode" situation, it means that your EFS folder is broken.
If you succeeded in restoring your IMEI and you still stuck in this Safe Mode, use this guide:
Method 1
Open root explorer.
Navigate to /efs/FactoryApp/
Open "factorymode" file as Text and edit it:
Change this:
Code:
OFF
To:
Code:
ON
Open "keystr" file as Text and edit it:
Change this:
Code:

To:
Code:
ON
Reboot device.

su
Then click enter. It will ask for super user permission, give it permissions.
Write the following & click enter:
Code:

Will heimdall work as an alternative to restore the efs.img? Like this: heimdall flash --efs efs.img ?
It is used from download mode, like odin, so would work even if you cannot boot.
This Method, in Moto x?
tamirda said:
Note to forum managers: Please make it a Sticky Thread, It should help to all users and there is no use for this tutorial if it is in page 3
Hello XDA Users,
I think some people here know who I am, so I will jump on the "Introduction of myself" for now.
Recently, I have faced many questions & problem of fake IMEI, of damaged EFS folder. So I made a little experiment on my device(GN2).
First, I backuped my EFS folder in 2 types - one is .img and the second is tar.gz.
Then, I deleted my EFS folder using ES Root Explorer. Which made my device to be on somethine called "Permanent Safe Mode" - You can not get out untill you fix your EFS folder and change some values.
This is permanent safe mode:
After I did my "research" I have managed to make several methods to backup & restore EFS, which should make your life easier and better.
First of all, Disclaimer:
I'm not responsible for any damage caused by using these methods, all methods tested by me, so it should work on your device too.
This is for I9505 Only!!!!!!!
Let's continue.
What you must have:
Latest base with latest modem and latest kernel - very important since in the latest versions samsung prevented the option to install old modems/kernels, so if you install old kernell/modem it can show you wrong IMEI.
Rooted device with the latest Super User
Latest busybox
PhilZ Recovery
Terminal Emulator
Root explorer - Can be ES File Explorer with working root option or just a root explorer from the market
A working EFS backup(In order to restore it...)
Time & Patient.
Important Notes:
When installing/downgrading firmwares, several people suffered from Fake IMEI. This is because the new firmware messed up your EFS folder, which means that you can not restore EFS backup until you are on the latest version, latest modem and latest stock kernel, recommended is XXUBMH1(right to 05/09/2013)
Some custom roms include modem installation in their rom installer. Due to modem flashing in recovery, some devices might get Fake IMEI. My recommendation is before even starting to use this guide, please try to install the latest modem via odin from this thread:
http://forum.xda-developers.com/showthread.php?t=2192025
When installing modem via odin, make sure you select PHONE and not PDA
You will find at least one method that works on your device, so don't give up after one method.
Read all guide and pay attention to all small details.

Method 1 - .img backup
First method, is an automatic backup/restore software.

You can try and share your experiences.
From my personal experience with another device the dd method in terminal works just fine
Sorry but null IMEI isn't fake IMEI
Difference:
Null IMEI means you don't even have any data for the IMEI oh and it's bad!
fake IMEI means you do have a data which is corrupt. Nothing more only digits has been changed.
There's a different between those
I remember having null IMEI and my backup didn't help at all service center was forced to swap motherboard to get IMEI working.

I already discuseed this, you need to restore your EFS backup after you flash the ROM that you made the backup with.
so flash XXDMF1 with ROM XXDME6 (or DXDMF1) and then restore EFS.
if that didn't work. then flash XXDME4 then OTA update will give you XXDMF1.
If you can't recieve OTA updates and you have Root, then tell me so I send you my XXDMF1 and DME6. (dr.ketan has DXDMF1 which you must try first).
After every flash restore efs then restart to see if it is fixed.

first of all make sure your phone is rooted. then download mobile odin Pro (you need Pro version to maintain root or simply root again). then download this file:
http://www.mediafire.com/download/ena68zhyjhwpc78/update.zip
Edit: this will make your mobile a french mobile, so don't flash it just get someone to convert it to a modem.bin or modify it for your country.
now open mobile odin pro and flash the Stock ROM XXDME6.
after it finishes open mobile odin pro again and go to update file, and choose the file you downloaded above. then flash it.
you you have build number XXDME6 and buildbase XXDMF1
now restore EFS by using this app: https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en
Code:
Put your EFS file on your mobile (External SD Card is preferred on the Root of the Card, so its location should be /storage/extSdCard/efs.img).
name it efs.img for easier use (if it was an img file).
now in the terminal type this:
SU
then grant it superuser permissions.
then type this:
dd if=/storage/extSdCard/efs.img of=/dev/block/mmcblk0p3 bs=4096
it will show you numbers if it was done correctly.
then reboot your phone and everything should work correctly. Reboot again to make sure.
In case it didn't work, then Flash the DME6 ROM, it should come with DXDMF1 , then try restoring EFS again.
tell me what happens with you.
@mysterionTM
what is your configuration of your phone? (your rom)
I put thanks to you both

what do you mean permanent way? why would you need DME4 if you have a higher better one?
you can flash DME4 (it comes with ROM DMB4) modem alone and keep it permanently, but if your EFS backup was when you had anything other than DME4 then you can't use it anymore, you have to recover EFS everytime.
just use XXDMF1 (since your CSC is DMF1) and restore EFS. don't see any reason to use an old modem.

on your other phone , you had EFS backup on DME4. on this phone, your backup is on DMF1. DMF can read DME backups, but DME can't read DMF backups because samsung changed the EFS read type on DMF1. so once you go DMF1, your EFS partition is changed permanently!

you're wrong
I was only backup on DMF1 on the other note 2
I followed this procedure and are able to put DME4 :
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
but on this note I can not!

you can change the IMEI as you like using Maui META but now the NV data file itself is corrupted so the phone won't boot
So i need a valid NV Data file to be able to fix the IMEI

I'll upload mine (but modified IMEI), but which file?
is it the nvdata folder inside /mnt/vendor?

i guess so
NV Data NV Ram
I don't think it's correct, the nvdata folder only consist of GPS ID, BT MAC, WiFi MAC files.
The rest is a bunch of calibration files for sensors.
I'll try extracting using Maui.
Sorry bro, unable to extract it using Maui as well.....

Hey All,
My Phone's Begoniain [ 8/128 ] .
I tried flashing a custom rom on my phone ended up with the bootloop.
So, I tried flashing the stock rom and my IMEI number got deleted.
I used MAUI IMEI Tool to restore the IMEI. Later I realized that the NV Data got deleted ( NV Data is Corrupted ).
Now I'm unable to install MIUI and also not able to see any network related information ( IMEI No, MAC, Sim, Wifi, Bluetooth, etc., ).
I searched all sites, No results regarding [ Mediatek Helio G90T MT6785V ].
Can anyone advice me on this.

how much priced you for this.?
primero debes resetear el efs (con UMT o por TWRP) para dejar los imieis en "0", luego para repararlos pasan el firmware y ponen un nuevo imei o restauran el que tenian y listo

MOD EDIT: English Translation Below
First you must reset the efs (with UMT or by TWRP) to leave the imieis in "0", then to repair them pass the firmware and put a new imei or restore the one they had and that's it
