Ok just in case anyone is looking like I was for three days. . The nv_data folder that many remember from s2 and s3 is not on the s4.. It is just the efs folder. . I did an efs-pro back up. .a nandroid.. And used philz cwm to get an efs only tar and img.. feeling backed up now hope im right and was not mislead.

So I was trying to take be smart and decided to back up my efs folder with efspro.. One it had no option for verizon model the latest version has snapdragon and international so I chose snapdragon. Back up worked then I tries the NV.. did the ##dmmode# dm on and nv backup which said command sent but my phone just rebooted so I am not sure if it did anything. Question is there an app that can do this from the phone.. if not why not lol.. and if not is there an easy way that I am missing to do this... I am very newb.. my last phone was a charge and all I did was flash like nuts.

Recoveries can back it up. It's one of the options in twrp when making a backup.

Um so you can also do a dd of the efs partition I don't know the partition number but it will be something like dd if=/dev/block/platform/.../by-name/efs of=/sdcard/efs.img
Update:
Nandriod backups work on file systems that are lower than recover. This means recovery/system/data/cache. You will have to use a backup partition tool or the dd method above.

;| ohh I did do an efsprofessional but when I selected the phone they didnt have sch-i545 they had snap dragon or international so I dont want to trust that. I also copied the folder with file explorer but I with my limited tech skills can only assume its just not that easy.. Ill have to try the DD method just need to find the copy paste commands since thats how I live with linux. I also did the NV backup with the same program but the phone just rebooted so I think that didnt work. I posted on the forum for the tool but no response yet. Thanks I am glad you posted I would crack if something happened and my backups did nothing..

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?

Theres also a Dev called Odia that can restore lost EFS/IMEI folders.Costs i think but its worth it if you cant get it done yourself.Send him a PM.

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.

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.

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.

There are a few apps in the market which can backup your efs folder.

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!

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.

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

I've been trying to backup my EFS folder from my US Cellular GS3 (SCH-R530U) with very little luck. A couple hours of searching has pretty much everybody recommending the use of EFS Professional, so I grabbed that (release version 2.0.26), Problem is that it crashes after initializing the ADB server, hitting me with event name "CLR20r3". Searches to troubleshoot that error suggest that I check to make sure my .NET Framework is up-to-date and that I don't have any other ADB processes running in the background. Both of those have been done; error still pops up.
As-of-yet the phone is unrooted; I've been trying to backup the EFS before I begin a root and subsequent flash to AOKP (for starters). Does an unrooted R530U have issues backing up the EFS folder? Any ideas on how to fix the error EFS Pro is hitting me with, or alternative EFS backup options?
Many thanks in advance.

I'd suggest a start from some modern recovery f.e. PhilZ Touch or CWM 6.0.3, both of them have very nice feature of making a backup, including your /efs folder. Then you can flash original stock recovery if you wish or simply flash any ROM you want because custom recovery is everything you need.

I'm no expert, but when you hit reboot in TWRP, fix permissions if prompted to do so and try again.
I know from experience that you are able to both make backups and flash ROMs, though.

I figured out what it was. TWRP couldn't make a back up because there wasn't enough storage left on the System, because the System takes up 6gb's alone...
