Hi,
I have managed to lose my IMEI and empty my /efs folder. I was using the Gingerbread Beta 2 ROM provided by Whitehawkx on my Samsung Vibrant. Everything was great for me, I was loving it and was using it as daily driver. Until one day, my cell was in my pocket and I realized it was overheated. I removed it from my pocket and saw that it was frozen and had the double rainbow screen. I removed the battery to switch it off and restarted.
Since that moment, I lost all the files under my /efs folder and also lost my IMEI. As a result my phone does not recognize any SIM card. I can use all other functions like wifi, bluetooth, etc. but cannot use any phone functions like calling, sms, etc.
Please please please help me out to resolve this problem. I do not have backup of my /efs folder. I do have nandroid backups of my JFD, JI6 and KA6 ROMs. (if that helps in any way)
I have already tried going back to Stock JFD with clear efs checkbox checked using odin but no luck...
Please Help & Very Thanks in advance...
P.S. Let me know if you need any more details...
This is tricky, but it can be done, I am not sure how much your phone is jacked up. But here is a link explaining how to do this, read carefully a few times before you proceed:

Thanks oka1,
But before your reply I did something because of which I am screwed even more
While trying out everything, I flashed my Vibrant with the International Samsung Galaxy S ROM - 'I9000DDJF2'. I also used the CSC file that came with it.
This did not solve my IMEI problem but then now I can't go into Download mode or recovery mode as we do not have the home key that International Galaxy S has.
Please help me get in Download mode or Recovery mode so that I can get back to Vibrant ROM.
we do have a home button. use that to go to DL mode.
how come did that messed up your eds? was it told that you need to backup your efs folder?

Got lucky, managed to get into Download mode. Found this post 'http://forum.xda-developers.com/showthread.php?t=728698', the key was - "If you still can't enter download mode, you may want to try holding down the volume key + the power button. Plugging in your USB cable may also aid your efforts to enter download mode."
But this does not solve my lost IMEI and /efs problem. I did not know about backing up the /efs folder :-(
I am trying my hardest to try and restore my IMEI...
just get a replacement. that's the easiest way I think.
is your phone unlocked?

Hey Im looking now through some old threads, might have a fix.
I did that too, but luckily, after that, i bricked.
Backing up /efs will avoid any problems like this?
Potential Fix
I attached a screenshot of the files that should be in your efs folder. When I unlocked my phone, it required deleting all of the nv files besides the log, which leaves -
The .android folder is empty
The .imei file contains your imei number (found under your battery - put it in without slashes)
The imei folder which contains bt.text with your bluetooth mac address and a code file with the word XEN
I would recommend ODIN back to stock, root, set up this file structure (leaving out the nv files), then download the sgs unlock tool, and run it. People have reported success using the unlock tool to rebuild nv_data.
If this fails try reading through this thread - http://forum.xda-developers.com/showthread.php?t=879189&page=3
Thanks guys for helping out...
@iynfynity - My phone is unlocked. I can't get replacement since I am not in US. I bought it from ebay.com.
@pvspencer22 - I will try the way that you have mentioned. I thought since I am not in US, I can request someone from US to share their /efs folder contents. A nice guy from xda was ready to do that but then he was not comfortable :-(
Ya I wasn't to comfortable with it. It just doesn't seem safe for me to give someone else my IMEI. And plus I dont think it would work on your phone anyways, because the efs file wouldn't match your phone

I tried these ways, no luck :-( Seems that the only possible way to resolve this is if someone agrees to share the contents of /efs folder of a working spare vibrant phone. But then no one is ready to do this...
Wonder if it could be possible for YOU to give your information from your phone & battery to someone on here that could make edits to their files with your info and send it to you??

Not a bad idea

My original IMEI was 351801041232857.
My phone model is TMo Samsung Vibrant, I bought it from ebay.com.
Not sure what other details would be required as the only thing different is the IMEI, rest would be just as any other Vibrant phone.
Currently I am on stock JFD (downloaded from xda) and my /efs folder is completely empty.
Guys, please let me know if any other information is needed. I would be more than obliged to provide it. I am just trying out all possible ways to resolve the problem and I deeply appreciated each and every message coming my way... This is what makes xda so special...
As I have said, my handicap is that I am not in US, else I could have easily asked T-Mobile to solve this problem for me...

I have nothing against you mate, you were just trying to help... I have completely understood your concern...
About the second part whether it would work or not, we need to try it first to figure out whether it works out or not. That is why we are here... trying to help each other out...
Guys, someone please help me out with /efs folder contents of a spare Vibrant phone...

reply if you still need help. I got a solution as long as you have the backup efs folder.

Thats the main problem, i do not have backup of my efs folder. My efs folder is empty and hence I am requesting someone to share their efs folder contents :-(
I need a vounteer helper who can share his efs folder contents...
Please...
I bought my Note a week ago and swore I wouldn't flash any roms until the stock ICS version came out (was told it was supposed to come out in 3 weeks). Still couldn't resist rooting it and freezing the bloatware, but now I'm itching to try some of the ICS roms that have been released lately. I just can't resist.
I come from the Captivate and remember that a good time after I started flashing roms it was announced that backing up the nv_data.bin file in the EFS folder was something we should have all done before flashing.
Is it the same thing with this phone? I don't see a nv_data.bin file but it's entirely possible that there may be something similar that I'm not spotting.
Thanks.
No input? Though the files in the /efs folder don't look like they hold any information that can't be lost I've archived it anyway.
Does anyone know if there's any other information I should save that would be unrecoverable after I flash a different rom?
I used Efs Pro.
Get some SDK tools correct for your system here. http://developer.android.com/sdk/index.html Also some .net frame work 4.0 from possibly here http://www.softpedia.com/get/Programming/Other-Programming-Files/Microsoft-NET-Framework-Client-Profile.shtml Finally the business end of it, Efs pro from here http://forum.xda-developers.com/showthread.php?t=1308546 Thanks to lyriquidperfection. At least this is what i have done. Hope all goes well.

Had the same initial thought and also archived the EFS folder. Screenshots of my APN settings (always, saves headaches) and various other settings. Upon looking around the forum, surprisingly found little mention or info in regards. So the best i could come up with, i tried, worked. Backed up as a .img and as a .tar . Overkill perhaps, but felt safer in doing so. Then posted above. (Sorry for the crude/improper use of links?)
1. I read something about loosing your IMEI after rooting / installing a rom. Is there a way to avoid this or restore it after?
2. I was wondering if there was any estimate as to when voodoo will be available for the i9300(searched the forum for voodoo really quick with no luck)
I apologize if I'm asking stupid questions, I'm just trying to learn everything I can and be 100% prepared for when I get my device.
For imei, first thing I always do since the S1 is first root the phone and in root explorer or similar I make if copy of my 'efs' folder. I make copies on the SD cards then transfer to PC just in case.
With the S3 it also has another folder - 'factory' but it contains the exact same files as the 'efs' folder. I also copy that just in case.
I always test by deleting the original folders to corrupt my imei then I copy the backup folders and imei comes back. I know there are other ways but I prefer this method. Copy and paste.
As for sound, there is a thread on it but personally not sure when it will be ready. Don't follow it much because my sound is already awesome using siyah kernal audio tweaks.

I dont get you??
He means that you can download a stock ROM from the Bible that he linked and you can extract the files you need from there with something like 7zip or Win.rar or Winzip. Then you will have all that you need.

I suspect that this request is a veiled attempt for someone to unknowingly post their EFS folder that you have requested so many times. I surely hope that this is not the case because that would be bad. Your other threads asking for the EFS folder have all been closed. If you are looking for all the files that are in root / of a stock Vibe, that is where the EFS folder resides. That is not ok as you are essentially asking for it but in a veiled and mysterious way in order of trying to dupe someone to uploading it. And that is not Cool.
I already answered you on the Changing motherboard fixes EU bug thread that changing the motherboard will get rid of the EU bug but you won't be able to get any info that was on your original Internal_SD.
If you are willing to offer a reward, EU BUG permanent fix reward 20$, then really you could just take that $20, hold on to it for a bit, get $20 more and just buy an new motherboard off Ebay. They are only $40+. Just install it, flash back to stock JFD and you will be good to go.
First of all if any 1 I'll give me his system files then he surely will not give his efs as he I'll be a knowing what's efs folder all about .....and I just want to confirm the size of all these files but mainly those files which are unable to load at the start up
Hi all
I want to explain my problem, and first thing i tell you that i'm an italian guy so excuse me for my bad english..
So.
What's happend.
I have my Galaxy S3 (i9300) by 2 weeks and i like flash roms. The efs folder problem is not new to me 'cause i got this problem few weeks ago with a note 2 but all gone good thanks to a Backup of this folder.
This time is not going so well like last. The first thing i've done before flashing the 4.2.2 update was back up the efs folder.
I haven't back up with a program but i just copied it on my pc using root browser. Obviusly i checked if the files was good in the inside of the folder.
All ok, last night i flashed the update and obviusly (My fortune :') ) my efs was corrupted.
I simply copied my backed up efs folder on my pc on the storage and then replaced with the original "recreated by system" efs (imei 0049..)
This last time worked with my note 2. But with sgs3 seems the opposite.
I tried everything, just copying, replacing only nv_data.bin, trying to find the imei on hex editor..everything.
But i observed that when i copy the "right efs backed up" replacing the " recreated by system efs".. when i reboot i find another time a "recreated by system efs".. i know that 'cause when i copy and replace the efs the files on the inside shows the data (h/m/s) that is not the same as when i reboot..
So i ask to you, is there another solution?
I searched on the web few hours and all of the solutions explained on the web doesn't work for me..
So i ask to you:
1- Why my backed up efs folder is every time replaced by "system recreated efs"?
2- Is there a method for find the IMEI on the nv_data.bin so i can see if the back up i done is good and not corrupted?
3- Maybe doing a flashable zip of /efs folder will solve this?
4-Is there a method to write on nv_data.bin my IMEI?
Thanks to all, you are my unique chance to save my phone.

I watched your thread and maybe my problem is that i have an efsv2 but my firmware is EMC2 (march 2013 rev2) so it can't read efsv2 folders.
I'm downloading an EMG4 firmware.
I will tell you if it works.
If it works i have to do you a favor!
