I must have wiped the EFS folder in CWM not realising it's important. If I do a factory reset or wipe "data" in CWM, the phone IEMI code is lost and it only allows emergency calls. Only a restore from the image brings it back to a usable state.
I have a image backup, so I'm sort of ok. So it's running ok, but that means I cannot sell the phone off, as I cannot do a reset without bricking it (and I cannot delete accounts)
Is there anyway of recovering IEMI, NV_DATA.BIN?
I wouldn't be fiddling with this phone if I had enough RAM in the first place. I have tried QPST but I cannot communicate with the phone, it just says not found.
Is there any other way of copying NV_DATA.BIN modded to my IEMI to EFS folder?
Is it a simple fix?

Use galaxy toolbox to restore imei and search the thread how to use it.
will it recover iemi from a nv_data_bin that I don't have?
tried it, still does not work. EFS partition file is about 1MB when backed to micro sd card. Is this right?
does anyone have a backup of theirs and could they edit iemi for mine?
I've been having wifi problems too, it keeps on dropping out with the wifi address. This one of the problems with lost efs/iemi?
getting it looked at by phone shop, I've restored the image, done a factory reset, unrooted it, do I need to do binary counter reset?
IMEI partition is very small, that's right. On russian 4pda.ru some people repaired their IMEI by installing stock rom via odin. (that, wich comes with 4 files.)
I have downloaded the single file and repacked versions.
Which version of Odin should I use? I cannot get odin to communicate with the phone, is there another way of flashing the phone?
phone FIXED! Managed to unzip the repacked files, used odin 1.85, flashed the three files, rebooted, then reset to factory defaults, and can now dial out!

Hi, I've had the same problem, I want to install jelly bean ROM on my galaxy ace s5830i, but tried it before and I only read a forum about backing up efs folder afterwards, so it was too late! Now I have an imei number but the efs folder is empty, so there's no way of installing a ROM like jelly bean without being able to recover the imei number later, EVERY TIME I INSTALL JELLY BEAN IT KNOCKS OUT THE IMEI! Does anyone know how to recover the details in the efs folder if you have accidentally wiped them?

1. You don't install Jelly Bean. You install themed Gingerbread ROM
2. You won't see anything in EFS folder ever. If you can't see anything in it, doesn't mean it's empty.

Hello, I own Galaxy S2, after I tried to update firmware to JPKI1 ( Downloaded from samfirmware), the flash went ok but after that, I noticed the Signal is gone, IMEI and I CANT do any reflashing either to stock or custom, I used ODIN to do the flashing procedure, each time I flash a Firmware nothing happens the old (JPKI1) version still there, I'm confused what to do now DIY or Service center?.
Regards.
sounds like you may have nuked your efs folder.
If you ment to write I noticed the Signal is gone and the IMEI
Hopefully you have a backup

Can you flash a new rom & rooted kernel via odin
then look to see what you have in /efs
If you have any backup files under /efs, say /efs/_nvdata.bak you may be in luck (I was)

Well, I tried to flash another kernel and another rom but the weird thing is after finishing the flashing, nothing happens at all, the old version is there, even if i do a data wipe, the data doesn't wipe at all, every thing is still the same, thanks for the reply.
BTW: I haven't found anything in efs folder.

Currently on Checkrom XWLA4 2.3.6 with Speedmod kernal.
Last night I performed a Titanium backup and a Nandroid backup in preparation for an upgrade. I had previously performed an EFS backup sometime back. I didn't perform the upgrade, just completed some backups. Anyways over night something seems to have gone wrong with my phone. I wake up to find that it's showing there's no SIM card detected and then when I checked baseband version and IMEI both are showing unknown as well as a bunch of other fields.
I've tried a number of ways to restore the EFS folder. I've tried GSII_Repair, EFS Pro 1.9, kTool, and a couple of manual methods. All of which give the same result.
Some strange things that I noticed, I have an EFS folder inside of an EFS folder. The /efs folder seems to have less files then the /efs/efs folder. Also /efs/efs folder was the fold that had the .nv_data.bak and .nv_data.bak.md5. Not sure if its suppose to be that way.
Wondering what the best way to try to get my phone up and running would be.
Thanks,
Lu.

The problem:
(a) You performed nandroid backup in CWM recovery while your phone was connected to the charger. This is a known bug of almost all versions of CWM recovery.
(b) Baseband missing means that your Modem was wiped off which happened as a result of the bug in (a.)
Further Explanation
a. this has nothing to do with your /efs folder
b. If baseband is missing then the phone can never read your IMEI, hence no network
Possible Solution
a. Download Modem (CWM zip format) of your choice. If you already have a modem then, skip to next step
b. Disconnect your phone from the charger
c. Boot to CWM recovery
d. Flash modem.zip you downloaded
e. Reboot phone
check your phone info after reboot (give your phone about 5 minutes to settle down), your IMEI, network etc should be back now
good luck

it was definitely plugged into my usb port charging at the time. just tried what you recommended and still the same issue. i wouldn't be surprised if everything that i tried today with the efs folder made it worse.
any recommendations? would it help if i tried a fresh install of xwla4 (2.3.6) or something newer like xwlpg (4.0.3)?
really need to get this fixed. any info or step-by-steps are greatly appreciated.

You shouldn't have messed with your efs partition after the issue came up. it's suppose to be the last solution and not the first one.
ok.
try this:
-Remove your SIM.
-Reboot to CWM recovery
-Flash modem
-wipe cache partition
-wipe dalvik cache
-reboot phone
-Allow phone to stay for 5 mins.
-check your phone info, check IMEI
if both are back fine, just reinsert your sim and continue normal life.
let me know what happens

Not sure what happened or how this happened but while I was retrieving the information from the About Phone screen the baseband was showing unknown and then once I glanced back down to get some more info, it just appeared and within another few seconds I got my IMEI and cellular services started working!
Thank you very much kind sir! Greatly appreciated!

When you have this kind of problem, messing with /efs should always be the last solution and not the first one.

in your own case, where baseband and imei was missing, changing anything in the efs comes last because, if it's other thing related, flashing modem , firmware and things like that should fix the problem.
Then the last thing is messing with /efs partition.
Why, because, efs partition is not touched during flashing of ROM/firmware. It contains sensitive files, and should only be modified as last resort.

I did a back up on sd and pc. Before. I had only flashed from rr 2.6.1 rom to a jb rr rom after a few days of not changing any thing it came up network locked enter code etc. Whilst out driving so nothing I changed iko. Now it still changes imei but I have a stored working backup so I jus restore that and reboot. Would a modem and rom have to be compatible? I've never changed my modem do I need too and is it flashable? thanks
I only have these problems cos standard isn't different..

Nice to hear that
I was running CyanogenMod 10.1 ROM with SiyahKernel v-1.9.1. My phone ran out of battery, so I went to charge it, I turned it on and it became stuck at the ''SAMSUNG S3 GT-I9300'' logo. I left it there for 30 min. nothing happened, I took the battery out and the same thing. So I decided to flash again the Stock Firmware with ODIN (obiously ), It flashed it with no problems, but it is the same. I tried so many things and searched in so many posts and nothing helped me. Sorry for writing long and for bothering! Thx!
Plenty of reasons why your phone won't boot, running the battery until shut down increases the risk of corrupting files or even partition. If the stock rom flashed via odin successfully then there should be nothing wrong, you did factory reset and clear caches before you booted, right?
factory reset from recovery

Samsung S3 GT-I9300 purchased in the UK.
Its my sisters mobile and i think its soft bricked. She told me it just happened and she done nothing. I received the phone in stock condition.
The phone was orignally stuck solid on the first startup title screen and would not go any further. This is what i have done so far:
1. booted the phone into recovery mode which shows E:failed to mount /efs (invalid argument)
2. wiped cache partition
3. wiped data/factory reset
4. Installed Odin3-v3.04 and downloaded I9300XXDLIB_I9300OXFDLI1_I9300XXDLIB_HOME.tar
5. Connected phone to Odin and flashed the above .tar file which completed sucessfully.
The phone rebooted and it still got stuck on the first startup title screen.
I then looked for a different version and downloaded I9300XXEMF1_I9300EVREMF1_I9300BVEMF1_HOME.tar
this version also installed sucessfully onto the phone after repeating what i had previously done.
The phone reboots and now gets past the first title screen to the animated samsung logo but then keeps looping the animation.
The blue led in top left corner is on and is pulsing from dim to bright constantly while it loops.
Getting a little progress with the 2nd version i kept this on and patched CF-Auto-Root-m0-m0xx-gti9300.tar ontop of it.
Still the same looping when it gets to animated samsung logo
I dont know if this would of helped but i then tryed downloading the NV Generator to make a new IMEI file but cant get
the phone to respond to NV reader writer program.
Iv downloaded Adb and tryed to push the IMEI file onto the phone but it fails with error E: Signature Verification Failed
Im a beginner and this is the first time iv tryed to fix a phone and iv hit a brick wall and not sure now if im wasting my time.
can anyone help me get to the next stage?
Restore your backed up EFS would be the first step .
Do you actually have an I9300 as the NV tool is for a different phone
jje
Does your phone have a cwm or twrp now that u cf rooted it? If u do..then just flash a new rom over it after a clean wipe..(not stock) hopefully your phne should reboot to the new rom..otherwise ill think of another way..put the files into the extmem card using a card reader..or take a tar file of the new rom and flash it after clean wipe..works for me everytime i f up

apply update from ADB
apply update from external storage

wipe cache partition
apply update from cache
sorry if this is not what you meant. im not sure what cwm and twrp is short for.

Ahh yes I get you now. sorry lol.
what if I get a backup /efs from another phone. would I be able to mount it via sd card, then edit the efs to suit my phone so its not a clone of the phone iv got it from?
iv just flashed ODIN_CheckROM_V4_XXBLG8
it gives alot more options to fiddle around with. I think I could fix this phone to be honest if I keep looking into it.
OMG!! after installing the rom I just posted the phone has booted up and im in
I don't know what to do now.
is the efs fixed? should I make a backup?

this is what I flashed and it seems to have fixed it?
can anyone explain what has happened, I would like to understand what this rom was able to do that the others I flashed before couldn't.
if it booted it doesn't mean that EFS is okay

do you know what I could do from here to fix the efs?
should I try and pull anything from the phone onto my computer now that its booted?
when I goto status it says IMEI unknown
I know my imei number is behind the battery, how do I register it?
the fact that it booted changes nothing.
you can't repair the EFS if you don't have a backup
what is EFS? is it a folder? a file?
can anyone else explain a little more?
it is a folder.
to explain a little more - you need a new motherboard because every EFS folder is device-specific
I cant get the phone to connect to my wifi. Kies is not picking up the phone either.
is there a way I can download apps to my pc and load them onto the phone? I would like to try and get root explorer installed to see if there is an efs folder.
i tried EFS PRO. it has generated an efs.img file, is it useful?
this is what i done to get it, im not sure if its correct. can anyone tell me?
i went into Backup and selected Device Filter: International Variants
i ticked the block device box and clicked the backup button.
the operation was successful and it created the zip file with the efs.img inside it.
i have pulled this zip from the phone using QtADB_0.8.1_
does anybody know if this file can be used to fix the problem? or has it made a backup of a corrupt efs folder?
After having S3 for some months, I decided to update it to 4.3.
So I searched online and saw some tutorials how to root and install costum ROMs.
I read few tutorials to be sure how to do that and after all went good and the ROM installed, One problem has rised: NO SIGNAL!
so I wiped all and installed a ROM STOCK.
After that the signal came back "half way". It's showing signal bars but I can't call to anyone, even after calling to my provider...
I just don't know what to do. Please help

well these tutorial you've read were either very bad or you haven't read them correctly, because probably you missed the important step of the efs backup. see therefor the stickies thread or the thousands of similiar questions here in the q&a.

That is your backup flash with odin
( When you flashed a custom rom it probably backed up your efs some roms backup by default)
I would just backup your efs you have at the moment just in case you have problems flashing. You will then be able to return to how your efs is now even though it is not fully working..
Or try this app >> https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool <<
The phone has to bee rotted to use ktool?
I also understand from the link you did about the EFS that there are two types of base bands and if I have an efs backup that I did on V1 baseband so I can't restore it on a v2 baseband, so my conclusion is to get back to 4.1.2... correct me if I am wrong

good that you found efs backup
yes you need root. or you use the recovery philz touch to restore your efs (then you don't need root, but a custom recovery).
well samsung roms based on 4.3 need efs v2, so you have to go back to 4.1.2 to restore your efs v1 backup.
if everything is working again, I would suggest you to use oding to upgrade to 4.3, because then everything should be updated correctly (but keep your efs backup, and make another one, just to be sure)
then you can try out again custom roms based on sammy 4.3
So what is the best option to restore it?
Because before I tried (while 4.3 stock rom was installed) the flash it with Odin but Odin always crashed when I was uploading it to Odin.
With kTool I tried before but when I am clicking on the button it says that it restored but he didn't asked for directory, when do I need to put it?
The same story with phliz, I also tried with this and he don't asks for directory, only asking whan the ending if the file-tar to bin...

Just extract the efs.tar and copy its contents to /efs.

Where is this folder located? I can't find it
and does it for xTool and phliz recovery destinations for teaking the recovery from?
Edit:
I found the /efs. I dind't know that I need to use root explorer...
I exchanged the files with my back up and suddenly instead of 0049 IMEI I got 0000 IMEI.
I tired also to flash a modem and also didin't work...

Hmm... try installing another EFSv2 modem, then do the /efs copying part again.
Suddenly after so restarts, the IMEI got back
But... The SN now is 0000000000
You'll need to correct the permissions of the files you've copied. Try searching for someone who already did this and duplicate what they did.

Ok,
I tried something new. I flashed a new modem, backed up a full backup and then installed a costum rom 4.3.
the IMEI GOT BACK! And even the SERIAL NUMBER!
But I think the serial number is not good because he has 16 or 17 (I don't remember) digits (numbers and letters).
But still i have signal bars but can't make or receive calls he says: "No registered on network"
For the finalle, I tried ARIZA patch but he Is stuck on 0%...
here I stopped, I really don't know what to do.
Don't use the Ariza patch once you've got your IMEI and SN back. Maybe try flashing a new stock version of Android with a EFSv2 baseband so as to not go through the copying fiasco.
