[WARNING!] Backup your /efs folder before you flash

***Please backup your /efs folder with Root Explorer or similar before you flash any ROM!***
Here is what happened to me:
a) I flashed some firmware which changed my phone's product code.
b) I tried to restore it by editing the nv_data.bin file contained in the /efs folder.
c) This made my phone show a corrupted IMEI (004999010640000).
c) A corrupted IMEI means lots of trouble, in my case I cannot download apps from market anymore
d) If you don't have a /efs backup your only chance is sending your phone to Samsung for repair (it's illegal to modify IMEI and moderators will ban you for discussing this subject in their forum).
The /efs folder is located in the root of you phone, it is only visible with Root Esplorer or similar, and contains IMEI and product code information which is signed and matching, don't change its contents unless you have a HEX editor (I wrongly used wordpad instead).
If mods think this warning will save some headaches to forum users, they could sticky it.
Probably it will help reduce IMEI modification discussion as well!

imma do this now just incase...
took one for the team huh... good looks...

I understand that modifying your IMEI is illegal here but there should be considerations on how to restore the IMEI back to original state if it was damaged by a firmware flash and no usable nv_data backup, the information on the nv_data is encrypted and from what I understand the IMEI data on nv_data has to match the hardcoded IMEI so Im not sure if its possible to change the IMEI on the SGS by just changing the nv_data contents.

Wow, thats a

this was discussed to death a few month ago and only firmware to do so is JPC, which no one would flash now.
And you shouldn't toch those files, as they are signed (you have to delete so they are recreated from back up). Go and search a bit (look for specific topic and topics with "Release" in them).

I was able to flash JPC ages ago even before the warning on the efs came out, there was a guide on how to restore the IMEI from the back up.. sadly on my end the back up was also corrupted, Not much of a big deal for me as in my place IMEI duplicates dont really matter.

guys i have unlocked my samsung vibrant to other carriers, all is going good. then i accidentally deleted my new efs folder. when i copied my old efs (from the locked phone) my IMEI was screwed up. but still my phone is working fine all that is not good is my IMEI is changed to a different number which has a lot of zeros.
how can i fix this problem?

i got a backup of my efs folder but do anyone knows how to restore it back

But it's always safer to keep a backup of that folder. Any malicious code can delete/modify the ocntents of that folder (with su permissions), and you can't get it back completely by flashing, only by backup.

I backed up my folder and hopefully i'll never need it, but how would I restore it in the case my imei is broken?

Probably a noob Q but how do you backup nv ? Tried kalpik's command line but seems that it doesn't work on jpa

That's why I don't care my productcode. I think it changed to KOR long time ago.

I already have JPO. should I still backup efs for later flashes or did i have to do this on eclair? My IMEI is still OK. Never had JPC though

Some people say that JPA is ok, BUT JPO corrupted their IMEI. Its what was said.

I am sorry that my post annoyed some senior members whose opinion I respect and to whom I am thankful for their job here on XDA.
I only own an Android phone since a month and previously I only visited WM 6.5 forums, so I missed all the discussions about this subject.
That's why I thought it would be a good idea to have a warning stickied somewhere for total noobs like me.
For those needing a way to restore their backups it depends on what they did to save their data:
-if they have copied the /efs folder with root explorer or cp command just copy them back to your phone's /efs folder.
-if they have a efs-backup.tar.gz file in their internal memory they have to type in ADB or terminal emulator the command:
su
busybox tar -xvvzf /sdcard/efs-backup.tar.gz

I just checked the esf folder on my pohne with astro file manager and it's empty. What's with that?

Astro is no good for that, you shoul use root explorer or similar.
If your IMEI is ok you definitely have a good /efs folder content.
Search forums for ways to backup its files (either use root explorer or adb or terminal emulator).

i move my efs folder to sd card and i moved back do root and now i dont have emei number anymore me cell is infuse 4g whats can i do or its gone...

So, just to make sure.. I opened Root Explorer on my galaxy s2 (with villain rom 3.0) and copied the EFS folder and transfered it to my sdcard, then I also copied it from my sdcard and stored it into a backup folder in my computer.
Does this mean that if my phone somehow becomes corrupt and i lose my IMEI and what not, I can just restore that efs folder with the one I just backed up and my phone will work again?

yes backup - if fail - restore

And it'll be greatfull if you guys can even share me your origin /efs folder (without nv_data.bin offcourse). Mr. Qbanin @ samdroid.net can help us for the nv_data.bin fixed, but only copy this file can't revise G3s IMEI...
Pls help and we can find out the 100% method for restore IMEI @ our phone in the future. so we can do the flashing freely without worry losing our precious IMEI anymore.
Many Thanks and Best Regards

From a thread about the Galaxy S it seems that the IMEI is stored in encrypted form in a file called nv_data.bin. I suggest that in future anyone who flashes keeps a back up of that particular file just in case.
I can't suggest a fix for you if you don't have an uncorrupted backup of it, but maybe reading this thread http://forum.xda-developers.com/showthread.php?t=771158&page=11 could help? (it seems to suggest deleting the file might cause it to be regenerated, but I'd be careful with that!)
Confirmation of this by someone who has a spare/free one Galaxy 3 would be handy, but I dunno if we have anyone around who does. (Ideally we'd test the effects of deleting nv_data.bin, corrupting it with random data and the effects of restoring the file)

AHHHH! Just thought as I posted this (sorry for DP but it deserves it) - Your nv_data.bin file is stored on /efs. In principle you should be able to remount this partition and fix everything... I have no USB cable to hand, but when I do I'll give you its /dev/block/stXXX designation.

Dear all rooted i580x user!
Pls kindly help compare your "good" /efs folder... maybe mine missing something???? due to one time Erase Phone EFS using Odin Debug Options.
Mine /efs now as below:
Code:
/efs/nv_data.bin
/efs/imei/.nvmac.info
/efs/.files/.dm33 (empty folder)
/efs/.files/.dx1 (empty folder)
/efs/.files/.mp301 (empty folder)
And if you can do adb shell, it'll be very kind of you by sharing your good backup stl4 and bml4 - for research purpose (those partitions did not content any of yours personal data - so PLS HELP!!!). Pls do the backup partions as below and share your img here if possible.
Code:

Hi
I lost my IMEI too but I have a back up of my /efs folder.
So if you still need the files just tell me.
My story is ...
The phone was locked to SFR France, I tried a lot of instructions but nothing worked for me.
Finally I found one who said change the files in the /efs folder to jpc, here it is:
http://forum.xda-developers.com/showpost.php?p=7930170&postcount=7
what I got:
1. the phone is unlocked now and working (call, sms, ...).
2. I lost my IMEI, its now all zeros like 00000000!
what I have in my /efs folder now:
.files (folder)
imei (folder)
root (folder)
batt_cal
nv_data.bin
nv_data.jpc
nv_data.jpc.md5
specs:
GT-I5800 Galaxy Teos
Android 2.1 Update 1
I5800XXJG3
Protuct Code: GT-I5800DKASFR

/efs is located on /dev/block/st14 it should be configured the same as /data

I lost my IMEI too. If you get any methods of recovering it, please let me know too.

Please describe how you lost your IMEI, so that others don't do this way.

I am working on the very same problem and willing to help.
But for this, I need original nv_data.bin files.
Of course (just like ANY "remote" unlocking, NOT only the imei-based code) this involves sending your data (IMEI) to me.
Well, I am a member for a while, and thus may have earned a degree of reputation.
Anyone willing to help (NOTE: you need to HAVE IMEI..) please drop me a pm.

[TUTORIAL] Remounting/restoring/backup the /EFS partition

/EFS partition contains a lot of information about your phone, f.e: wifi/bt mac address and your IMEI (nv_data.bin).
It's highly recommended to backup the whole partition, or at least copy the files from the efs directory.
CORRUPTED OR NOT?
You can check if the efs is mounted or completly damaged with this command:
adb shell
mount
You will see something like this:
{
"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"
}
Red part means /efs is mounted.
IF YOUR PHONE HAVE CORRECT EFS PARTITION:
1, Root your phone - there are several methods to do this.
2, Install root explorer or Estrongs file explorer and copy /efs dir to your sdcard - this will copy the files.
or
2, Make a backup from the whole partition -this is better if you flash a phone with wrong ops, the only way to restore using this backup.
Backup:
adb shell
su
dd if=/dev/block/stl4 of=/sdcard/efs.rfs
Restore:
Add efs.rfs to an unix compatible tar and flash with odin as efs file:
IF YOUR PHONE /EFS IS CORRUPTED:
Flash the included /efs tar with odin:
This will remount your efs partition and (if you have a backup or fixed nv_data.bin) you just need to overwrite files with a file explorer.

confirm WORKING 100% ... all you just need later is the nv_data.bin fixed
Thanks so much for your efforts

I am using I5801 JPB (with restored bootscreen and Rooted via SuperoneClick)
while using "adb shell" command at Better terminal its showing "adb: not found"
I flashed my I5801 from JP9, JPA and JPB till date..
is it possible to restore the backup now..??

Because you need adb.
If you do on phone (Terminal emualtor) adb shell not needed, just su and the other commands.

how to make .tar file because backup file is .rfs format help me i want my imei back

ok, using the dd method i made the backup of my /efs to a efs.rfs file that have ~4 MB
But when i go to the efs folder (on / ) or see the copy i've made to my SD card, there is no files at all on this folder. How can we "see" those files (nv_data.bin) ?

Hi
For backup I simply copied my /efs folder to SD card using root explorer.
Then I modified nv_data files to get unlocked.
there was no SSNV in the files.
I have a working unlocked phone now but the problem is that IMEI is all zeros like 000000000!
Can I use that folder to restore my files?

Download the Tar Utility from GnuWin32's SourceForge Page.
Code:
hxxp://sourceforge.net/projects/gnuwin32/files/tar/1.13-1/tar-1.13-1-bin.exe/download
(change it to http)
It'll install the tar.exe executable and required dlls in C:\Program Files\GnuWin32\bin
Copy those to where you have your rfs (or you can add the bin folder to your PATH Environment Var, google for help on how to do that)
Now type:
Code:
tar -cf efs.tar efs.rfs

Yes, you can, just copy nv_data to /efs.
Windows users can use IZARC to create tar files.

[AROMA] EFS Backup Restore utility (Noob friendly)

EFS Backup Restore utility (Noob friendly)
What and Why
Before starting with this guide you must know what is EFS and why we need to backup it, still you don't know about it then Read This and come back.
OK so now you know why we need this and again before proceeding make sure you need device Rooted, If you don't have rooted device then first Root it (use this guide option 2 to root ) then join here directly to step 2
STEP1 : prerequisites
1.As said above you should have rooted device
2.Make sure you have CWM/TWRP installed. If you have stock recovery then you can use this guide to make EFS backup. But here described method is much easy and noob friendly.
If you want to install CWM then download this philz recovery and flash using Odin
STEP2 Backup EFS
1.Download EFS_baclup_restore-AromaV2.zip
2.Copy downloaded file to Int/Ext SD card
3.Switch off device and press Vol up + Home + Power to reboot device to Recovery Mod. Once it rebooted to recovery mode, selecy Install zip option from recovery
{
"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"
}
4.Select option choose zip from sdcard OR Ext Sd card depending on file you have copied
5.Select EFS_backup_Restore_Aroma.zip and select enter.
6.Now next screen you will have is Aroma installer. You can select option depending on your choice, where to store EFS backup. Here in example i have selected to make backup on both place int and Ext SD card
7.Once backup is finished, you will have msg like this. Now you can select next to exit.
8.Now select back and return to main menu of CWM and select to reboot system now.
After successful backup you will have MyEFS folder depending on location you have select to backup. You can see 20MB file efs.img in MyEFS folder. along with that you can see build.prop file too. Actually that file have nothing to do with EFS backup but just for capturing information of your ROM when you made EFS backup.
STEP3 : Copy to safe place
Copy MyEFS Folder along with files in it to safer place on PC / Cloud to make secure extra copy.
RESTORE
Follow first 5 steps as mentioned above in 'Step2 Backup EFS'. Now here you have to select option
'Restore EFS from intSD' OR 'Restore EFS from EXTSD' depending on location you have choose to make backup.
Select one of it and click next.
Now exit from aroma, reboot device.
PS : If you already have efs.img 20MB file which you have created with other tool and want to use this to restore EFS, you need to create MyEFS folder and to put efs.img file to MyEFS folder in sd card manually.

Change log :
[13Sept13] V2 released : All user of first release requested to use V2 to restore EFS, First release have bug in restoring and may fail to restre. If you have made backup with first release no need to make backup again, issue was with restore only. Sorry for inconvenience.

In case need this

Good tool Dr.ketan.
What is the difference between this tool and philz cwm efs backup option?
sent from my GT-N7100. Press thanks if I helped..

Nothing technically
But Philz recovery have option to make EFS quite internal and may be newbie don't knowing it. Also AFAIK it making backup as hidden file so again sometime newbie gets confused.
Here attached tool makes simple efs.img on MyEFS folder and that you can restore with other tool like AS_id's tool OR with Terminal emulator i have mentione in other thread.
Here i have illustrated in detail so it may become easy for any newbie.

So product efs.img file is same as all. And can be restore with other tools also.
One suggestion from my side,
Add date, time and ROM details in .txt file with this efs.img backup if possible.
I know you have backup buid.prob with it, but as noob we can't identify.
And thanks again for this nice tool. Adding this to this thread also.

I thought earlier to make date stamp, but i think it's have no use b'coz we can't remember on which date which ROM was there on our device.
Build.prop is giving information of your ROM which really we needs. just open with text editor file from device and you can find information in first few line.

Thx Doc for the great tool. You make people's lives easy :thumbup:

Great tool. It should be included in every aroma based roms.
However is the efs backup valid with any modem? I have the impression that they are related and newer modems effect older modems.

Great, thanks a lot!

See you have some misunderstanding.
This is different method of making backup, it doesn't make changes in contents of it.
Modem have no role directly. basically culprit is newer kernel. when you flash new ROM (so kernel) it lakes change in EFS partition which older modem can't read and so No IMEI.
If you flash new modem than again it will work. And tha't why i included to make backup of build.prop to capture ROM information at time of backup. So if you have created backup on older ROM, i recommend to flash older ROM - Restore backup - Upgrade ROM.

DR. Ketan you rocks!!!
Thanks for this valuable info for people like me!!!
You always anticipate mistakes made by newbies like me!!!! and make our life easy by making small installer zips like this.
Thank you once again!!!
Ashwin

And such compliments inspires to make all these possible!

thanks
Thanks for your easy guide

@ All
Who have download first release kindly use V2 to restore. I have foud a bug which may cause fail to restore. No need to make backup again if you have already made with first release, it was only restore issue. Sorry for inconvenience.

Thanks Dr. for providing very easy way to back up and restore of efs.

[Tutorial][SP][JB 4.3]External2Internal for xperia sp[UPDATED WITH WORKING LINK]

Hi friends,
At last i have found a way to mount external storage as internal and vice versa for xperia sp jb 4.3(.205). For this, you just need to have init.d support in kernel so your system can run a script on each boot which will do the mount in background.
Requirements:
1. Root
2. ((1. Busybox ))
((2. Universal init.d ))
((3. Es File Explorer ))
3. The attached script named "swap"
4. Patience and cool brain
How to do:
1. Install busybox
2. Install universal init.d
3. Make a folder in your external storage named "0" and put all the files of your external storage into it
4. Make another folder in "0" and name it "xInternal". Cut your files from your internal storage into it( So now, you have all ur files of external storage in "0", and all your files of internal storage in the folder "xInternal" inside "0"
5. Download the zip and extract the script(swap) and place it in /system/etc/init.d (Go to your root of the device with any explorer, i used es file explorer, then go to system/ etc/ init.d and paste the script there.

}
6. Set the permission of the all checked (-rwxrwxrwx)
7. Change the owner of the file to "system"
8. Change the group of the file to "sdcard_rw"
9. Reboot and Die!!! Becaue you need to cut all files from the folder "Android" inside "xInternal" and paste it in the "Android" folder inside "0"
(So you have the files of your previous inter storage/"Android" in the folder "Android" of your present internal storage{which is actually your external sd})
10. Enjoy!!!!!!!!!!!
Download script
Issues:
1. You will see in settings that your external storage is changed as the same size of internal storage but internal is same as it is. Dont worry. Just dont look at this bcz its showing wrong info. you can install file commander and see by yourself that the script works
2. Es file explorer will show you that your internal storage is replaced with your external storage, but at the place of external storage, you will just see obb. But its wrong also, dont worry
For your help:
Before using this script--
Internal storage: /storage/emulated/0 (size ex. 5 gb)
External storage: /storage/removable/sdcard1 (size ex. 16 gb)
After using this script--
Internal storage /storage/emulated/0 (size ex. 16 gb) [
External storage: /storage/removable/sdcard1 (size ex. 5 gb)

The script mount and bind /mnt/shell/emulated with /storage/sdcard1, so u have a folder in sdcard 1 which names "0", if u go in /mnt/shell/emulated/, u will see 3 folder named "0", "legacy", "obb". You already created "0", and "obb" & "legacy" will be created automatically, so your /dev/block/vold/179.33(/storage/removable/sdcard1) will be mounted as /mnt/shell/emulated/ and you will get your sdcard1 space in your internal, means /storage/emulated/0/. And you will see all your files of sdcard1 in "0" bcz u have put those in in a folder names "0" in your sdcard1. tricky, huh???
And if you are using this and avoid annoying low internal space, just send me thanks by pressing thanks button and encourage me to make more useful things and tuts in future
