Is there some tutorial to do a full NV backup on our phones? Want to make a full NV backup just in case I may hit the IMEI bug.
No because it doesn't seem to be a problem with this phone. However, just to be safe, I used an app called zipme from the play store to make a flashable zip containing the efs folder. I then proceeded to back it up to my dropbox. Just in case

yea, I made a EFS backup through TWRP but just want to be super safe with a Full NV backup. Got the IMEI "0" bug on the S3 and restoring the IMEI wasn't enough to fix it. I had to do a full nv restore to fix the phone.

Seems like something to ask the synergy team I guess, since they figured it out on the s3

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
Sent from my GT-I9100 using XDA App
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?
Brgds... /Tubgirl
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 .

If i have a siyah backup of my esf (a tar.gz and a img.gz) what do i have to do to restore my esf folder?
Search for/read the kTool thread on here.
I got stuck in flight mode yesterday and I can't get out of it.
I have seen i need to restore the efs folder but i don't have a backup.
Is there anyway of getting a backup of an efs folder?
If not how can get my phone back to working order? does it have to be returned to manufacturer?
Would I need to put my phone back to stock as it is now rooted if it needs to go back to samsung?
I have a full backup of my phone on kies if that works?

Search is your friend.
I searched this forum and found some intersting threads:
Here a user had the same problem and wrote how he could solve this issue => http://forum.xda-developers.com/showthread.php?t=1261948&highlight=efs+restore
Here is a tool to backup (&restore) efs folder => http://forum.xda-developers.com/showthread.php?t=1308546&highlight=efs+restore
And another user seems to have solved a similar issue => http://forum.xda-developers.com/showthread.php?t=1331701&highlight=efs+restore
Good luck !
yeh i found all those posts and have been reading them carefully.
Only thing is i don't think i can find the nv_data.bin file anywhere.
I have ES File Explorer installed and i looked in the EFS folder but it says it is empty!!!
when i used the EFS Pro it worked through it, i got a .img file at the end of it which is 20MB but i can't seem to view anything in it...
ok now im getting somewhere i found the nv_data.bak so im going to use the articles again and have another go.
I didn't realise you had to use the .tar for the efs backup to view the files
I'm still very much a noob and i was wondering if there was a consensus as to which tool between kTool and EFS Pro is the best and most noob friendly way of backing up your efs folder.
I was also wondering if there are any more precautionary steps one should take after rooting for the first time besides doing an EFS backup, a CWM nandroid backup and a titanium backup.
Thanks
kTool. Get it from Market, couple of clicks, keep one copy of your EFS on your external SD card and one copy on your PC (and copies on a CD/DVD and a couple of external drives if you're ultra paranoid ), go to the kTool thread on here & buy Hellcat a beer.
Done
If you're doing a Nandroid backup, EFS backup & Ti backup right after you root your phone for the first time you're well on the way to un-noobing yourself You'd be surprised at how many people who have been here ages don't do those things.
You could go to the trouble of using dedicated contact and SMS backup apps, but you can just as easily backup your contacts to Google, and you can restore them easily enough from your Nandroid backup. There's an app in Market called AppExtractor which allows you to restore individual apps, SMS, contacts and other stuff from your Nandroid. Haven't tried it yet tho.
But I'd reckon you've pretty much got it covered.
As far as backing up sms's goes I find sms backup+ to work really well, backs up your sms to your gmail account!

And in case of corruption of internal SD (Happens) remember to take backups of pictures/etc and store copies of your backups (nandroid/EFS/ETC) off the phone.
Rule of thumb, if you cant afford to lose it, back it up. Speaking of that, better make a nandroid and copy it to the PC
I currently have two b/u's:
-one generated by Hellcat's Ktool,
-one generated by Galaxy S Unlock.
Both live on my sd card, and on my PC.
Both tools available on Market (Ktool also on XDA). Ktool has saved my bacon once already.
Go with kTool, it works flawlessly. EFS Backup failed (freezed) first time I used it (luckily nothing bad happened do efs partition).
Also kTool can easily install new kernels, installing speedmod takes just few seconds.
This is my no 1 root utility (although it has... weird interface).
Best way to restore from a backup?

Ktool, Just deleting the whole thing with root explorer and copying it over, using a terminal editor to extract the backup over your EFS.
All should work.

Both apps have inbuilt restore features; they save .img's and .tar's to your SD. Ktool saves it to the root of your sd and Galaxy S unlock saves to a folder, and each app can call on these files upon you selecting restore.
As far as restoring the EFS via adb, that's one thing I have to learn still. I'm not sure whether extracting EFS from a nandroid is possible, and how it would be done, via adb, etc...

my phone has forgotten its imei. ive not flashed it in a while and restoring it with efs pro doesnt change anything. ive tried many times and my efs folder looks just like it should but the nv data files are blank.
warranty service is out as it got wet a while back .
if i cant repair it myself ill replace it and use it for a media device.
what can i do to repair this any ideas?
Without a backup, it's a service centre job (or a music player as you mentioned).

back up is not an issue i have tham but it wont take a back up from the pc in any way shape or form. also have unknown baseband
I'm referring to an EFS backup, BTW. Not a CWM/other backup. Without an EFS backup, you have zero options.
Now then...If you are talking about an EFS backup when you say 'back up is not an issue i have them but it wont take a back up from the pc in any way shape or form':-
A) What app did you use to make the EFS backup (or was it an auto-backup EFS made by Siyah/similar)
B) What are you doing to/how are you trying to restore the EFS
?
a copy paste back up and an efs pro backup of efs folder. copying and fixing permissions doesnt solve neither does restoring efs pro back up.
looks like its now a posh media player
Hi can i restore the efs from a cwm backup ? I can't do a restore from cwm as i get "md5 mismatch" error
Before Installing Recovery / Rom what should be backed up (except personal data) ?
I heard EFS should be backed up and made into several copies.

you are right.
First thing after root = backup your efs folder
Then after you got a custom recovery, making a nandroid backup is always a good idea.
and yes personal data is also good to be saved.
in addition i highly suggest you to read the stickies
after that happy flashing :laugh:

Well I rooted the device.
Used kTool(Verification screenshot: http://oi57.tinypic.com/s2gl01.jpg) to backup the EFS, got two files: efs.IMG & efs.tar.gz one is 20MB the other is 0KB this is normal? Cause the verification said there's an error of some sort..
I have SuperSU as Root controller, this ok?

Last time I did that somehow ****ed my phone up.. Not going to try. Also last time I lost my IMEI & Serial using the backup that I made via kTool restored it properly!
