i deleted efs folder 15 times done lot more so u cant say i had backup
you've got to be joking right?
and just for the info: it's not a 100 % fix
king_below_my_lord said:
First of all you should apologize to wishmas7er, he is right this is not a 100% fix, and you were able to recover your imei because your efs folder was still intact with the file containing the imei info, some people are not so lucky, if anyone gets their efs folder wiped clean or overwritten he/she is screwed and the only option for recovery would be warranty, otherwise he/she is stuck with a expensive media player.

You deleted your efs folder?
(technically it's a partition)
?? I'm at a loss of words, but as far as I have heard an efs wipe = screwed uptill now, I don't know how your imei got restored with the above process(just think about it how will a phone recover information not present on the device) anyway I am sorry if I offended you, I personally am not willing to take the risk of deleting my efs folder, so I won't be able to try it.
Anyway is your current imei same as the imei given on your phone box?

Sigh..listen mister I was and still will be polite, because I took into consideration that you are just a misunderstood newbie, we don't come here to insult or make fun of people but to help people in trouble in any way we can and a false piece of information like yours will be misleading to other noobs and will cause a lot of trouble I never in my comments went about calling you names or insulted you, and for your information let me tell you some thing's you should know
your efs,system,sd card,ext-sdcard,usb(if pluged),etc.. all are partitions and when they are mounted they appear as folders because linux architecture(which android is made up off) mainly shows them as folders ,even if you delete the efs folder only the data within maybe lost and not the actual efs partition wont get deleted. Now since you were very adamant about this efs deletion thing, even though I was sure that it was impossible, I went out of my way to ask one of the elite dev's about this :

salesale:
dont think so. probably is a joke
That is a copy of pm with salesale who is a developer who made the NeatRom for several devices like the S2,S3..
You see that^^^ the devs think that you are telling a joke.
So I am telling you admit your mistake and correct your statements about the efs deletion foolishness or one of us here will report this "wrong information" thread to a moderator who will delete this post, frankly I don't mind that in the least considering your rude and impolite behaviour.

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..
samsung galaxy note 2 lte 4g N7105
Hi everybody i'm new here i have a problem with my phone,my phone is rooted, 1 month ago i had this problem that my phone would not boot stay on samsung logo,i rebooted in recovery and say EFS failed,so i connected my phone to odin flashed a couple of roms but nothing worked, i saw that there was an option EFS clear so i did that but did not work either so i reflashed a rom and this time it worked but when it booted it didn't even ask me to enter PIN for sim and i noticed in about device there was no baseband and no network signal please help guys i would appreciate thanks.
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.
Btw try LEWA rom

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.

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!

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 :/

So this morning I woke up and i couldn't get on my carrier network.. Which made me wonder wtf was going on. So I tried to go into settings to connect, but it wouldn't let me. I then realized my IMEI number was "unknown" which made my face one huge questionmark. I've tried using this guide; http://forum.xda-developers.com/showthread.php?t=1264021
But I can't find my folder? BUT!!! I found a EFS backup on my internal sd card.. which is good. I just don't know how to use it now?
I have CM 10 Nightly built from about the 15th of December (2012) and Siyah kernel... I think..
The folder i'm talking about is a zip named efsbackup.tar.gz
Can anyone help me? I tried going back to an old backup I had from october, but it didnt work either..
Try using an app like kTool (there are others) to restore the EFS backup (but obviously you only want to try this if it's definitely borked). There's a thread devoted to it on here (and you can get it from Google Play) which should have instructions on how to restore with it (never had to restore one myself).
The backup would have come from Siyah, which automatically makes an EFS backup. If you manage to fix it, thank Gokhan

yeah, you've got a generic IMEI. Did you look under the battery? there's your REAL IMEI.
Still, dial *#06# and tell me what number pops up.
In that case, leave it till you're not tired. Last thing you want to do is do something silly & bork your phone. It can wait.

Well, you got a couple of guides to use those apps.
First of all get try locating the efs back up with root explorer app, so you can move it to a folder where hc ktool can restore it.
If that doesn't work get busybox running in the background and open gsii repair.
and if all the above don't work, your up for reading threads time.

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.

Don't be a jerk. If you're not going to help him fine... But your response was unnecessary on a developers forum where we are all here to learn and spread knowledge.
As for the question, your way is fine as well.

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.
