[Q] EFS Backup Question - Vibrant Q&A, Help & Troubleshooting

I've noticed that one of the steps in flashing CM7 for the Vibrant is to flash "vibrant-efsbackup.zip".
See link-http://forum.xda-developers.com/showthread.php?t=968291
The question I have is: Does the vibrant-efsbackup.zip file backup of your efs for you (as the name suggests)? If so, can it be used as a standalone way of backing up the efs partition, without having to use adb or terminal emulator? I'm not using CM7 so this would be used with Darkys 9.3 vibrant edition.
Thanks in advance!

Good question. Can the same zip be used to backup EFS if running deodexed/rooted stock Kb5?

Yes that will create a folder on your /sdcard called /sdcard/backup/efs and it can be used with this post:

What about doing what I just did.
I used root explorer. Went to /efs. Copied the entire folder. Then pasted to my internal sd card root.
Then to have a copy on my computer, I just copied onto my computers dekstop.
I have an entire copy of /efs folder.
Good enough?

perfect! i also just have a complete backup of my internal on my pc desktop for emergencies.

I think you have to mount the folder before copying.

Yes you have to be rooted I think, and you have to mount it to see it, you also can't see it unless you use a root explorer type app.

Issues: new rom, back up?

Hi everyone. I've just rooted my galaxy s 2, running on gingerbread XWKE8. I'm planning to install a new rom.have heard about various rom available.
1. Is villain 2.0 rom okay? The main purpose for installing a custom rom for me is to save battery as I'm outdoor most of the time. as of now my gingerbread is working well except for this battery issue. Is it worth changing the rom?
2.Was reading about titanium backup
I've done back up of my custom apps + system data on phone' s external sd card. I don't have paid version of titanium. Can't buy it either. (no credit card).anyway, shall i be get nandroid backup too, just in case? when i install new rom n use TB for restore, since it*
Has system data as well, won't it overwrite the old data on the new rom? it sounds un believable coz it thwarts the whole purpose of installing a new rom. So will there be an option of ticking individual files to restore as per my choice? (no pro version of . titanium). If so, how do i know which one to be restored?
3. If clockworkmode has a back up option why do we need a titanium backup? cos it gives a nandroid type backup?
4. Can clockworkmode be used to upgrade to a new firmware (custom our stock) or odin should be used as in rooting with a little modification (depending on if firmware has one file or 3 files)?
Please enlighten.
Thank you very much

1) See for yourself if it's worth it.
2) Yes do a nandroid and check this before changing rom.
3) Nandroid is a exact copy of your current set-up, restoring it would undo the custom rom flash.Titanium backs up your apps so you can restore them after changing rom.
4) Depends on how the files are provided. Both should be possible.
For a credit card alternative I use this.
Hi.thanks a lot for replying. How do I get nandroid backup? Do I've to use rom manager in order to do nandroid backup? Cos when I search for nandroid in market, it doesn't return any nandroid app as such.

So if I happen to dislike or have problems with a custom rom, I just restore the backup of my rooted stock rom and all is back to the way it was (all, data/boot/apps/settings ...)? I think it will be, but I just want to be sure.
Hi.thanks again. I've read that recovery mode back up or titanium backup doesn't backup efs folder . One needs adb our terminal emulater or root explorer to do so.is there any link that explains efs folder backup using terminal emulater step by step?

I already linked to the right thread, in the thread there are different commands. All you have to do is pick a method, create the efs folder, copy the command to the terminal emulator and hit enter.

VillianRom is nice I've been using VR since release and tried many roms en route and keep coming back to VR for some reason!
Best to do a nandroid via CWM Recovery so if any of your new installs have problems you can always wipe and go back to a working config.
I only use TB to backup app data, I don't like backing up system data as when moving from one rom to another if you restore you may encounter issues so always best to start from scratch to save any hassles.
Default [REF] Backup /efs folder. IMPORTANT.
This guide is based on a guide by Candanga on the i9000 forums, and some commands from supercurio
Please hit thanks on their posts and show them some love for the write up.
-----------------------------------------------------------------------------------------------------------------------
I’ve compiled a quick guide to instruct how to make a copy of the /efs folder. I’ve found in many threads suggestions about backing up this folder but the methods itself are very general. Most of the times they suggest to “root and copy the folder” with Root Explorer or similar, but usually it’s not that easy or it just doesn't work for everyone.
This guide ASUMES you have read this Excellent Guide by Darkstrikerfirst:
H E R E <-- Make sure to read the ADB Guide.
I recommend doing this with a Mobile just taken out of the box or with any Official ROM of its Service Provider. If you have already Flashed your phone with another ROM but its working fine, then you can use that /efs also.
Why the /efs folder?
This is a very sensitive system folder that contains Phone-specific information such as the IMEI (encrypted in the nv_data.bin), wireless devices MAC addresses, product code (also in the nv_data.bin), and much more. Often users trying to change product codes or trying to unlock the mobile will end up corrupting data in this location.
Why back it up?
Well, let’s resume it saying that backing-up this little folder will keep you away from Samsung service centres.
***WARNING: I take no responsibility to any damage caused by the methods cited and/or written here. Their sole purpose is to back-up data and not to alter in any way the integrity of the original files of the mobile***
What you will need:
* Rooted SGS II to get permissions as a SU (Super User) and perform the backup
* I would suggest learning a little about the terminal commands used (in case you are not familiar with them), as it’s better to know what you are doing rather than typing strings like a little chimp without knowing what they are; if you are a little lazy, then you have a good chance bricking your mobile. <- Busybox Commands(or Google them)
* Terminal Emulator by Jack Palevich (available from the market) <-Terminal Emulator or use ADB which is included in the SDK Development Tools
The standard prompt of terminal (adb) is a $ sign. Once you enter “SU” it will become a # Sign.
***NOTE: Make sure to keep an eye on the screen of your SGS II during this process, because it may request SU permissions [currently doesn't on CF-root]; else, you will get an error (just if it’s the first time). In Terminal Emulator you will need to reset the app after granting permissions cause it usually freezes***
*Remember: to use ADB you need to enable USB DEBUGGING under Applications/Development in your SGS II.
Here are 3 methods, I recommend that you do both Clean and RAW.
Basic, unix permissions lost :
Code:
su
busybox cp -a /efs /sdcard/efs/
Clean :
Code:
su
busybox tar zcvf /sdcard/efs/efs-backup.tar.gz /efs
After this, you will end up with the file efs-backup.tar.gz in your INTERNAL SDCARD in sdcard/efs/, which is a “tarball” or a ZIP of the /efs folder. That file is your backup. You can expand it with Winrar.
You can also back up the mmcblk0p1 (where /efs is stored) under /dev/block which can greatly support in recovering your IMEI in case of a screw-up:
RAW :
Code:
su
cat /dev/block/mmcblk0p1 > /sdcard/efs/efs_dev-block-mmcblk0p1.img
Same thing, the target is the INTERNAL SDCARD in sdcard/efs/, so go ahead and copy the file.
Hi theghost & thanks for replying. Yes, i had read that link . But being a starter in androids, i had some doubts n thought if someone else knows a more simplified thread. Eventually i followed the same thread only.
As the author said, there r two methods - clean & raw n he advises to use both. when u used raw , in the end comes- no such file directory exists. When i checked my files->sdcard , i could see efs folder n some files inside it (which wasn`t happening even with astro file manger) I copied the efs folder N pasted it into Externalsd folder (default Ext. sd card folder ?)
R my efs folder files safe now ?
Is there any other precaution to be taken , any files to be saved before i embark on installing New villain rom 2.0 as per instructions given here http://forum.xda-developers.com/showthread.php?t=1081368 .
Strangely efs folder saving point isn`t mentioned here , even though its so important. (But then may be its very basic) Is there any other basic that i should know ?
Thanks a lot again.
with regards.
Create the efs folder with astro, then use the raw method and copy the .img to your pc.

Thanks mate. I'm backing up only custom apps, not custom apps.

Mist that you already had the efs folder. If you already have something there your probably good. If you still want the raw method to work make sure you type su first and hit enter and than exactly copy the cat command (ChromeToPhone is great for this) it should work.
Didn't work out mate .

How are we supposed to restore efs.img?

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).

I will ask him to report here.
One thing he has fake IMEI now.This should work right?

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.

[Q]How do we backup our efs ?

This is important I think we should figure out a way asap
Sent from my GT-I9305 using xda app-developers app
install android terminal to your device
and try the command below
Code:
su
dd if=/dev/block/mmcblk0p3 of=/mnt/extSdCard/efs.img
Great I did it now I have efs.img which is 20mb is this my backup ? Jus curios how come with k-tool and i9300 it saves 2 files and much smaller. What's the difference
Sent from my GT-I9305 using xda app-developers app
compression level... if u wan a smaller file , u can download kzn or my rom and u can just backup efs with it without flashing rom..
nah 20 mb is fine thanks dude, I am just wondering why there was 2 files with the K-tool but one with this way
I am out of thanks I have been thanking the I9305 Devs all day, Dont worry another load coming your ways tomo lool
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
My god what rock have you lot been living under for the last year or so?
Download the POPULAR and VERY WELL KNOWN EFS Pro application from my sig.

there you have it, I have used your windows tool and it created the exact same EFS.img as does this command line
Code:
su
dd if=/dev/block/mmcblk0p3 of=/mnt/extSdCard/efs.img
But your software way is much easier and even has a way to restore it. thank you very much yeh i must of been living under a rock cause all i ever knew about was K-tool with my previous phone i9300, but K-tool does not work with the I9305

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

Then you put it safely onto your dropbox and voilà.

no need to back up efs folder just for rooting your phone! you can not find any files in efs folder until your phone is rooted and es file manage is enabled root permission.

thats because nothing was accessible until after root, dumping system was easy, but any other directory/file on the device wasnt able to be read after until being rooted..
samsung didnt even include tar binary so I dumped over adb, then CF helped root and then we dumped raw images!

LTE devices have a QualcommChip, where everything is stored in the nvRAM, the EFS includes only files that have nothing but absolutely nothing to do with the IMEI.

I backed up my EFS to internal storage but cant find it don't see no /data/media/SamsungTool/ (using EFS file explorer) just want to save a copy to the PC. What's the exact name of the backed up file so i can use the search feature? cheers.

Backup to your External SD instead.
/storage/extSdCard/SamsungTool/efs.img

For full backup, which partitions do you recommend?
Galaxy S5 SM-900P Partition table
you can still simply create a copy right?
I have always had rooted phones and my SGS 5 is no exception, it got rooted using CFroot in the carpark immediately on picking it up.
I have therefore always simply made a copy of the efs folder on to the external sd card which is then synced to my dropbox.
However I have not really kept up to date with developments in these areas, so my question is nowadays is this still enough to ensure the safety of my device and it's ability to connect to my carrier. In the past when I have had issues after flashing roms and things simply deleting the /efs folder and copying the contents of my back up into it and rebooting has always been sufficient to get my carrier back up and running is this still the case with the international SGS5 qualcomm variant or do I need to consider other elements?
When will it work for SM-G900V? I just rooted my phone today and would like to use this for my backups. I just tried it by using EFS backup and now it's stuck on a triangle with an exclamation mark that says Please Wait. Ugh! Help...
