[Q] EFS - Galaxy S II Q&A, Help & Troubleshooting

I would like someone to help me understand what exactly efs is.
A friend of mine will give me a rooted galaxy s2. I am currently a nexus s owner.
I know root and flashing stuff but i don't know what exactly efs is. I have heard that i need to back it up before doing anything to my phone.
How can missing efs harm my phone? Not to boot up? Does nandroid, back up efs too? How can i backup / restore it? I have also heard about an app that does that work but what if my phone doesn't boot?
Please, help me understand it.
(sorry for bad English if there are any mistakes)

Well EFS is the folder on ur phones memory wher all the smartphone data like WIFI, Bluetooth Mac address and the phones IMEI no are stored.
so a mess up with the same and ur phone will not wrk normally ie to say , No wifi connection or Blutooth devices connection or even no netwrk (if IMEI no is messed up).
So its always important to Back up ur 'EFS' Folder once u root ur phone and start using Custom ROM/Kernel etc.
Also Some Custom Kernel's like Siyah, Dorimanx etc will 'Auto backup' ur 'EFS' folder if u install the same
U can also BKP using 3rd party apps from play store
So that u can utilize this backup to restore all the imp data, if ur phone gets messed up for some reason
Hope this is clear for u

Thank you so much.
So, a missing efs folder can't cause bootloop, right?
Can i backup that folder by simply making a copy on my pc?
If i use a 3rd party app to backup efs and switch to another rom, i just reinstall the same app and, if there is a problem, restore the folder?
Which app do you suggest? is kTool good?
If i don't make a backup and i find a problem coming from efs, can it be fixed?

i would also like to ask something else...
on my nexus s i always boot into cwm recovery an flash whatever i want (roms, kernels...)
but i read that many people are using odin. i am not very used to this app so, is it safe to do it "my" way?
please answer my previews post, too

Somebody please help...

Don't bump the thread....you can find that answer with google or mere observation.
Check any stock ROM thread and you'll see.

EFS folder can make your device unusable.
Ktool is a good app to back up EFS.
It's always good to save a backed EFS folder in your computer plus another back up saved in your device.

Samsung galaxy S2 EFS Folder

I have a Samsung Galaxy S II with lost IMEI & unknown baseband, ( the source of such a problem usually is the corruptness of the efs folder or missing ), My question is if the efs folder is missing would it be possible to use another backup from another backup of the efs folder from different S2 and edit in the details needed?
You can restore from your backed up EFS folder .
Or search XDA >>> EFS will find a number of posts and some fixes .

Hi mate, I don't have a backup of the folder so can't restore
no, you can not use a efs from another phone as the imei is unique to each phone. you would end up bricking it.
You need to send it in for reflashing with specialized tools which will rebuilds your efs folder.
I have the same problem here.. any idea how to rebuild the efs folder?

Cant understand why people do not make a backup of the EFS. If they all took the time to read the stickies, they would know how important this is. Learn to walk before you start to run.

That's assuming they indeed read the stickies, of course.
Reading
Read Stickies is important, but sometimes there are procedures that don't work well, or as expected, so problems like this will appear and they must have a solution.
restore with a backup folder!
You may not of personally made a backup but a lot of roms and kernels do it for you automatically, so you may have one or more backups and not even know it.
Check if you have one in /data/.siyah if you have used said kernel.
Check your sdcard for any made by roms they usually make a folder named something like efs_backup
Last I looked in addition to the backup I made 5 minutes after buying the phone I have 20+ made from each rom upgrade.

As long as your EMS folder is intact and IMEI is correct, its not too late. There are a number of apps and programs to backup your imei. Ktool is one of the best and simplest to use. Also try EFS pro.

Mate when people buy a phone, they don't expect that their phone's EFS will get meshed up. In my case I have Galaxy S and my wife has Galaxy S2. She has been using her phone for year and half, no major problem. Last week it suddenly lost the network connection. I tried different SIM but still no good and started searching to resolve the issue and I found how to access IMEI. It was empty. She didn't do anything, no new apps installed. Mobile service provider can't help..

Advice for ROM flashing noob.

Hi guys,
Right so I own both Galaxy SII(personal), GT-S5830(business) and my wife has a GT-S5830. Located in the UK
Now I have been looking at the latest CyanogenMod and would like to install this ROM on my GT-S5830, as I understand this is one of the best custom ROM's available for this phone.
However every where I read advises me to first backup my /efs folder, only problem is I can't find this folder to back it up! So far I have tried EFS Pro and a few others, but they all fail or give me an empty folder.
Any help would be very much appreciated as I have been researching this since Friday and I'm pretty much ready to blow a gasket....
Dont ever try to touch ace efs partition as its dangerous. Many had hard brick their ace because of tinkering with that efs partition. Ace's efs partition is abit different from other device because it's hidden and unmounted upon booting.

If that's the case why is everyone telling me to back it up? I'm more interested than ever now lol, is the Ace the only one that has this partition hidden?
Everyone from where? I never came across any post here on ace forum that advice to tinker with the efs partition. And its stupid to advice to do so on ace because in order to backup it u need to mount it first and thats when disaster strike.

I thick it has something to do with IMEI coz some guys r loosing their IMEI after flushing custom Roms which results to no signal situation meaning ua phone is done 4 real coz there is no known way of recovering it 4 Our ace
I keep reading that it is wise to back up this folder before you start flashing new ROM in case you screw this folder up.
U read that on other device forum, not here on ace forum. As i said earlier, dont ever touch ace's efs partition.
But if u insist of doing so, theres a thread here somewhere guiding howto network unlock ace, and in the process also explain howto mount that particular hidden partition. May god be with u if u ever try to do it.

haha I already unlocked my business phone using that thread, didn't actually realize that was the partition it mounted.... silly me.

Seriously!? Why do you get people trying to act like a smart ass?
Maybe you should read my OP before you make comments, I used the search button, spent two days doing research and found nothing directly relating to what I asked.
If you don't have anything constructive to say then say nothing at all.
There are a few apps in the market which can backup your efs folder.
I never tried them though.

Don't listen to anybody who says to leave the efs alone. I don't have your device but I STRONGLY urge you to find a way to back up that file. If you have already rooted the phone then a good file explorer should allow you to make a copy and send it to dropbox or save it to your external SD. Even mass storage and copy/paste it to your hard drive on your computer. And yes... CyanogenMod is the very best.
Good luck!

Hello all!
I guess the APP Chainfire broken my IMEI, i already changed my rom and nothing happen.
When i did #*06# my IMEI is 0000000000000
reading some tutorials I saw that I need to back up the EFS folder but this folder does not exist!
What can I do to restore my imei?
If someone pass me the backup of the EFS folders I use it?
You're basically screwed and you need to send it for service
This was sent from a Galaxy Ace. Problem?
Aw! Thank anyway!!!: (

See the irony? U wanna back it up and in the process u actually ****ed it up.
Why would backing up something ruin it?

Because it wasnt a folder to begin with. Its a hidden partition that intentionally left unmounted on boot. In order to backup it u need to see it, in order too see it u need to mount it. This when disaster strike. Forget to unmount it and it'll be lost forever. And even if u do manage to back it up its still useless because theres still no known method to use it to recover ace's imei. this have been said many, many times before, yet u who is a senior member with over 300 post still clueless. Thats what amaze me the most :/

If your rooted use a root enabled file explorer (I use Root Explorer) and open it up to /. There should be a folder called “efs". Simply copy that folder and place it on your internal or external sd, then for safe keeping place it on your laptop/computer

I've been nervous about flashing anything else since I've read about 4 cases like this. I'm so freakin happy I found this thread! I've found the efs folder your referring to, but I don't know if I should copy the efs folder to my external storage or open it & just copy the IMEI folder to my external storage? Your help would be so very much appreciated.
Maybe someone should put this in general and try to get it stickied, as it seems like a necessary preventive maintenance?
Edit: I just backed up the whole folder to be safe, and I'm going to make a general post referring to this problem.

IMEI restore not working? HELP!

I know many people have already asked about their IMEI disappearing and i managed to restore my backup using Galaxy Toolbox before but i tried to restore my IMEI again and it didn't work. I then decided to revert back to stock via Odin and i successfully went back to a stock ROM but my IMEI is still missing and i am getting quite worried now. Have i lost it for good? I obviously lost it after flashing the data2sd-ext script by Amarullz if this helps towards helping me?!

I managed to finally restore my IMEI. It was very confusing but basically i had to delete the old directory/folder i had on my ext-SD and then download Galaxy Toolbox. Then i opened up the app and went to the restore option, it says it could not find the directory and tells you to make one with the backup i previously took beforehand when i had a working IMEI. So i connected my device, transferred the file into a new directory named 'GalaxyToolbox' and disconnected the device. Finally i loaded the app and restored my backup, rebooted and hooraaay my IMEI was back!! I can't tell you how relieved i am! I MUST donate to Doky for making such an amazing app! I think i'm going to leave the data2SD-ext script for now and maybe try other methods if there is any?
Oh and i love your S3 Ripple Mod by the way, i had to go back to Simplicity V5 and flash it again! Lol

what is the name of the "old directory/folder" and where do I find it? I really need to resolve this problem
I probably didn't explain my solution very well after reading back through my post.
It has been a long time since I faced this issue but I'll try and explain what I did to resolve the problem...
1) Connect your device to your computer and transfer the GalaxyToolbox folder (should contain 2 files inside) to your computer.
2) Delete the GalaxyToolbox folder on your device once you have transferred it to your computer.
3) Disconnect your device and open File Manager/Explorer app on your device.
4) Create a new folder titled 'GalaxyToolbox' with no spaces on the root of your SD Card.
5) Connect your device to your computer again and transfer only the file titled 'EFSpart.img.SAVE' to the new GalaxyToolbox folder you created on the root of your SD Card.
6) Disconnect your device and let media scanner finish. Open the Galaxy Toolbox app and select restore EFS partition. It will tell you it has found a backup and ask if you wish to restore it, click yes.
7) Close the Galaxy Toolbox app and restart your device.
Type *#06# into your dialer and you should see a small box pop-up with your IMEI number letting you know the restore was successful.
I know it seems strange that this method fixed it for me but I think the app itself creates a 'temporary' backup which is the backup of your currently missing IMEI number and when you try and restore it keeps restoring the EFS backup which has no IMEI... So starting from fresh and moving the original backup I made back into the GalaxyToolbox folder seemed to have fixed it for me.

Hi there,
Rather make a Guide on fixing IMEI, instead of posting here...It would be helpful to many guys.. :beer:

What if someone doesnt want data to be restored. Of course it was an option when we had no way of backing up IMEI
But now (for over a year), we can work on IMEI independently via Galaxy Tools, then what is the need of this method handling data and it also can cause many FC's
Yeh Bro. Its Just. If They Dont Want Data To Be Restore Just Flash De Stock Firmware. Ur Rite.

Wrong! I tried to restore my IMEI by reverting back to Stock ROM via Odin and guess what? It didn't work, my IMEI number was still missing! So the method you suggested won't work either. Like Areeb said, Galaxy Toolbox is your only friend here...

Galaxy Toolbox is not being my friend. I've lost my IMEI and I can't bring it back whatsoever.
Tried flashing stock but the efs folder is always empty. So the 9-step guide doesn't work for me (Or am I missing something?)
Please help guys. I don't have previous efs folder backups. But I do have nandroid(CWM) backups of the rom and restoring them doesn't help.

EFS its a partition with raw data, not contain files... so you dont need to see files inside te "folder"... to see if you have your IMEI you have to dial *#06#

Err no...I was following the 9-step process posted by OP to restore my IMEI and I can't find those nv_data and all those files(required in 9-step process)
I've already checked *#06# and it shows an empty box

I agree, if you managed to backup your EFS partition via Galaxy Toolbox beforehand and you are facing an issue with your backup not restoring as it should then follow my mini guide on the first page of this thread. If however you didn't take a backup before you lost your IMEI then you'll have to follow the guide from this link -
