So I was reading about backing up your /efs folder and I was wondering if backing up your device with CWM through recovery, will that also back up /efs folder?
Thanks!
i dont now this but you can just copy the efs folder and paste it at your computer.its so easy
If you want you can download nitrality apply from market, which can automatically do a backup for ya

just copy the files might not be enough, permissions and ownershiop etc is lost. Look in this thread for info how to backup /efs
http://forum.xda-developers.com/showthread.php?t=1068193
I'm wondering the same thing... Does CWM backup the /efs folder?
No. There are apps that can do same (Hellcat's kTool being one), and some kernels automatically make an EFS backup by default (Siyah for example).
Edit to add - For clarity, CWM will not make a separate backup of the EFS. As it essentially makes an image of the phone, obviously the EFS details will be included (everything is included), but I doubt you can extract the EFS folders/files on their own from a CWM backup. If there is a way, I'd certainly like to know how to do it Would be handy to know, even if I do backup EFS whenever I do a backup as a matter of course.
So as long as I've made backups using CWM and then suddenly my efs folder gets corrupted, a simple CWM restore would repair the efs?
On the other hand... in theory (I would never try this) wouldn't that mean that if I did a CWM restore on a different SII that phone's IMEI would change?

Hmmmmm....Basically when you restore a CWM backup, you go back to whatever state your phone was in at the time you made the backup.
Now, if you borked your EFS, and if you restored a CWM backup, would this fix this EFS issue. In theory & based on the CWM backup being an 'image', you'd reckon yes it would.
In practice, I'm not about to delete my efs folders & try it out tho
So far as the IMEI is concerned, no, I don't believe it would. Reason I say this is because I know people who have taken a CWM backup of a phone they've had to return for replacement. Got the replacement phone, and restored the CWM backup on the new phone; essentially cloned the old one. And that hasn't messed with the new phone's IMEI.
At the end of the day, people who don't make EFS backups are insane IMHO (you probably guessed that from my sig). Given it takes literally 20 seconds to make an EFS backup with kTool, and another minute to transfer a copy over to a PC, there's no excuse for not making a backup.
Edit to add - Interesting questions/thread BTW I know who could answer these questions definitively for us. Odia. He's the EFS king on here. Can sometimes (often ?) recover IMEI's when there are no EFS folders/files to work with. How ? Who knows. Voodoo maybe ?
Ok, I'm no expert by any means and please correct me if I'm wrong, but wouldn't a complete efs backup include imei?
The reason I'm asking is because suddenly my phone can't make/receive phone calls with my current carrier (other carriers still work). I restored a previously made CWM backup but it didn't help. Today I read about efs and what it contains so I started to wonder if maybe that's where the problem lie. I've only made CWM and Titanium backups so far because I had no knowledge about efs.
Brgds... /Tubgirl
Easiest way to tell if it's an IMEI issue is to check the IMEI. If you have your actual IMEI in settings/about phone, that obviously isn't the problem (whatever you do, don't post your IMEI on XDA. Ever), if you have the generic IMEI 004999010640000, then you've got a problem.
If you do have the generic IMEI, then we can look at options to possibly rectify it (sometimes possible, sometimes not).
If your IMEI is fine, the problem lies elsewhere & you're worrying about nothing There are a million things that could cause the problem you described.
However, no excuse for not making an EFS backup nowish if your IMEI is OK & keeping one copy on your external SD card & another copy on your PC (and even another copy on a external drive if you're really paranoid).
I just used the IMEI example to question whether efs is included in CWM backups or not. My IMEI is just fine but since I'm so reluctant to send my phone in for repair I'm just grasping for straws here Thought maybe my problem was related to efs since I suspect it's not included in CWM backups. Anyway... since I never made a "real" efs backup my question is pure academic. I'm afraid my phone needs to be sent to a service center. System restore didn't resolve my problems either but I'm pretty sure that wouldn't resolve efs problems either.
Brgds... Tubgirl
Did a bit of digging & found this. It would appear EFS is not backed up in a Nandroid backup after all despite it being somewhat of an 'image'. So I guess that answers both our question.
No, system restore more than likely won't solve EFS issues. Normally the only way to fix it short of having Samsung do it is Odia/whatever method he uses (which he won't divulge; and fair enough. I'm sure it's highly technical).
If you need to send your phone in for warranty service, do a format cache, data, system, & sd card in CWM. Then flash a stock rom in Odin, then use a jig to reset the flash counter.
Obviously once you root a phone and/or run non-stock firmware on it you void your warranty and should have no expectation of warranty service, but many people have been able to get same by doing the above. But in saying that, there have been people on here who have followed these steps & been 'found out' in any event.
Unless it's a case of actual damage to the phone caused by use or whatever, if it's a hardware fault, you might be able to get away with it.
WHich method do you use to backup your efs?
I use Siyah kernel which automatically makes an EFS backup & dumps it in the /data/.Siyah folder. There are also apps which enable you to make a backup, I've used kTool in the past & there are others (names of which escape me; search on here/Google Play).
I'd recommend kTool (search for it on here/Google Play) as it isn't kernel or rom dependent, it backs up EFS to /sdcard/efs.img & also allows you to verify the backup. You can then transfer a copy onto PC, external drive or whatever in case the worst ever happens. Quick, easy & no fuss.
Thanks a bunch... I'll search for it.
No probs

I saw this thread was about CMWbackups, and have a quetion about it. decided it's better to ash here than start a whole new thread
The CMW backups; does it backup EVERYTING?
So if i forexample have some movies on my external SD card, and then takes an CMW backup..... Next i delete everyting on this SDcard, and then flash the CMW image,,,,, will my movies then be back at my SD card? Will they be back at any other place at the phone? or will they be totally gone?

No as said it does not back up EFS .
It takes an image of the firmware OS and applications on the internal sd card .

Hi all !
if i restore nand backup from another phone on my phone + restore my orgininal EFS folder does it mean my phone will work perfectly without any surprise ????
thanks a lot

totally not recommended. you could be coming from different android version, or even if same version, different manufacturers may have different setup.
if you feel adventurous, you can try just reinstalling the "data" portion though, that is where your installed apps are placed. but be warned it also contains some previous system settings which may not be compatible with sgs3.
better alternative is to install Titanium backup, it has function to read from nandroid backups so you can pick and choose what you want to extract from there.
First of all this is the wrong section to post this, go to the q&a section instead.
If the other phone was not the same exact model of phone then DO NOT restore the nandroid. Like the other commenter mentioned you can use titanium backup to save and restore apps or even use it to extract the apps from the nandroid.
Hi all,
I remember my first Froyo rom on my GS1 was provided as a nandroid package..
Questions go in the Q/A section
Fyi, nandroid doesn't touch the EFS partition or the bootloaders, or radio, just the system, data, cache and boot (kernel) partitions.
You *can* restore another person's nandroid onto your phone, but its really not a good idea (someone shipped roms as nandroids for a bit...), and you shouldn't need to touch the EFS unless something goes wrong, and a rom should never touch the EFS.
Edit: As people above say, don't restore a nandroid from another model of phone onto your device, if you want to move data from phone to phone like that use titanium backup or the like.
i want to copy a nand backup from a S3 orange 16GB onto my phone S3 SFR 32GB, because i have no solution for a "NO SMS,NO CALL BUT INTERNET WORKING" problem

Well in that case at your risk by Nand i hope you mean a CWM Nandroid recovery .
Its often best to have the same version of recovery to restore backup if first attempt fails ..
Be far simpler to flash a stock SGS3 Orange rom via Odin .
jje.
I have GS3 i9300 International version.
My EFS partition has been corrupted.
I already have the backup available i took with EFS backup pro but when i now connect through it it doesn't pick it up even though i have put it in the same directory.
I also tried to backup the existing EFS folder (Which doesn't have anything in it) using Root Explorer in Phone but got an error 'Can't locate Mount Point!"
How can i restore my EFS folder again? Any suggestion will be helpful as i have been trying to read all what is available at XDA.
There is no IMEI and baseband available. I had the stocked firmware when this happened with CF root and Siyak Kernel.
I have checked in CWM Recovery mode.
All partitions are mounted except EFS and i am not able to mount it even in recovery.
So after like 24 hrs, i am finally able to restore everything back to normal .
Since the efs partition was not mounting, i used the following commands to do so manually in terminal
Code:
mke2fs /dev/block/mmcblk0p3
mount -w -t ext4 /dev/block/mmcblk0p3 /efs
The link that helped me realize this was
http://forum.xda-developers.com/showthread.php?t=1857811
After running this command i had signals and Wifi begins working but IMEI was turned to generic.
Then i turned to EFS bakup pro and this time successfully restored my efs folder and getting my origional IMEI back.
So all this taught me that flashing and tinkering with your android phone carries a huge risk and we should all be prepared to face such issues if decided to do so.
But really, what's the fun if we don't .
Following are some issues that i faced during this whole process which i am sharing if anybody else gets in the same situations
- The first thing i did was to flash the stock firmware but this lead to an unrooted phone again
- I used CF root to gain root privileges again but supersu was asking for binary updates before giving root permission to other programs.
- So i downloaded SAMSUNG GALAXY S3 TOOLKIT which is an excellent resource for everything related to rooting, flashing and backing up GS3.
- I rooted with busybox so that EFS backup pro can be used.
- Since my GS3 was not having mobile or wifi signal, this toolkit helped a great deal.
- One small thing that i missed was place my EFS back in a folder named "EFSProBackup" which is to be placed in the same directory as the executable of EFS Pro so that it can recognize it in restoration tab.
I hope this will be helpful if anyone gets stuck in this issue.
Oh glad you resolved it
This shows how important an efs backup is

I had ruined my i9000 same way and used it for a year with generic imei. I had to copy paste the efs folder everytime i rebooted the phone. Now i am on i9100 but i havent yet backed up my efs, can you guide me how to do it?
Download EFS Pro from here EFS Pro.
Connect your phone with pc via USB and make sure you are not using USB Mass Storage mode.
Start EFS Pro. Obviously, you need to be rooted and have busybox installed for this application to run.
Your phone information will be displayed once it's connected.
Create a backup of your EFS Folder either with a .img or .tar extension.
And keep flashing hassle free .

2)IMEI-UNKNOWN
3)MOBILE NETWORK-UNKNOWN

Further info:-
1)i can locate an EFS folder in the normal file manager which is empty
2)in the root explorer i can see an EFS folder with 18 files in it.
plz help thanks in advance,waiting for a quick response from your side
file manager shows empty because it is not operating with permissions to see it. This is not relevant.
use root explorer only
Just flash MG5 stock ROM from India. If it is still broken, send it for repair. Simple as that

I did exactly the same way and took a back up then flashed a custom rom and lost baseband version and imei, i then flashed back to stock rom restored EFS via EFS pro but the issue still remains.You can see my numerous posts in this forum,plz help me out thanks in advance
I've flashed roms and mods on my Sgs2 since I bought it 2 years ago. I've bricked it a few times and I always managed to fix it by myself, I only asked for help when my WiFi stopped working and I couldn't get signal at all only emergency calls (Never found fix for WiFi).
Anyway, I'm facing a similar problem now with my IMEI, I had this problem before and I learned how to fix it but now nothing works.
I've used EFS Pro, Restored a nandroid, flashed a stock samsung JB ROM (even though I don't think ROMs do anything to efs) I used kTool from Hellcat and the only way to make it work is doing my nandroid restore (CM9.. old nandroid backup) and copy pasting my efs folder I have backed up, however, If I copy paste the folder using another ROM (thats how I always fixed my corrupted imei) it doesn't work anymore, It only works once after restoring nandroid CM9, If i flash CM9 Odin it doesn't work, any ROM I install gives me corrupted imei. this problem started happening since I flashed stock JB ROM, I NEVER could use stock JB ROM without losing my IMEI, and I wasn't able to put it back by copy pasting efs folder (always used to work when i had this problem) another thing ~ I used NukeWipe Script ~ before moving to Android 4.2.2 now I only can use my phone with CM9 from my nandroid and fixing the imei there by copy pasting my backed up EFS. If I flash anything else my IMEI gets corrupted and I can't fix it with anything! hoping for some help, I would like to know how much will it cost me to fix this, take in mind that I'm from Mexico and USD is pretty expensive here
PS: I also tried the tutorial of Recover IMEI in 9 steps and it didn't work.
When I restore my nandroid I have a corrupted imei and no signal, my nandroid doesn't have a file explorer so I download one from market.. how do I download one from market if i have no signal at all and corrupted imei? I don't know ... I don't even have the 3G icon or any signal and it says no service but internet works fine.

Back up your efs folder with another app like galaxy s unlock or something (some apps make a copy of the EFS folder while other apps make an image of it), copy them to your PC then flash stock with mobile odin and see what happens.

I managed to get my imei back, codeworkx helped me, all i had to do was restore efs and then flash stock GB check if i still have my imei then flash ics then check if i had my imei then flash the old rom i had (mcm 4.2.1) and i had my imei but ... i tried to update to 4.2.2 nightly and my imei got corrupted, can't restore it while using 4.2.2, I couldn't use stock JB because of this, im guessing this is happening in 4.2.2 because they're using new stuff from stock JB.
Any ideas?
Could be, tattoo EFS on your arm just in case.

Hi guys,
Only recently did I recover my phone from a soft brick and since then; learning and living everything XDA and Android I decided to flash CyanogenMod on my phone. Loving it! Aside from the terrible Trebuchet launcher. I since downloaded all my apps and the like, flashed Philz recovery. Anyway, the following is everything I have backed up on my computer and all the files I have. Have I forgotten anything?
I am asking if you can actually read this and make sense of what I'm asking, do I have everything in case I end up screwing my phone I have everything needed? The user Darke5tShad0w was extremely helpful and he drilled it in my to backup the efs file for my S3 but I am unsure if I actually have backed that up, however there is an actual efs backup on my phone's internal memory in a folder named clockwork mod, I'm unsure though if I do in fact have a backup of the efs.

Sorry, I know it's difficult to read but I've tried to get all the information across and attempted to make it readible. Italics are folders while bold is like the root folder containing what I need.
Reason for all the stock files is in ever the case I need to restore to my last rendition of TouchWhiz, install Touchwhizz and reinstall the stock recovery.
Would it be worth doing a nandroid backup of my current CyanogenMod settings and what have you? Would the process be the same? In case I ever softbrick, wouldn't just using the Installer be enough.

Hello again.
If you did it all through philz like was said in the other thread and it didn't fail when you did it you should be sorted.
If you want to make doubly sure another app like ktool to create another efs backup.
Remember to keep a copy on your computer or somewhere else.
And yes it would be a good idea to do a nandroid backup now you have cm up and running.
