Hi
I have searched many threads with regards to missing IMEI and Baseband unknown.
There are many solutions including the 9 step guide and also the app called S2 Repair. I had this problem and i used S2 Repair and it worked a treat. I then used Galaxy S Unlock and that also worked a treat.
However I did a software update via kies and on phone (i wish i never did now) and I am back to no IMEI and Baseband Unknown and S2 Repair no longer works ? After lots of reading i think S2 repair is tring to repair the wrong files ???
My question is this ....... I did not make a back up of my EFS folder before using S2 Repair or Galaxy S Unlock BUT i have got all the files in the EFS folder in the root of the phone EXCEPT (dot).nv_data I DO HAVE nv_dat and (dot).nv_data.bak files
I also have folders in the sd card named S2Repair which has "efs_save.tar" and "efs_save.tar.gz"
WILL I BE ABLE TO USE the files in the S2Unlock folder ?? . In this folder there is the efs folder and these files
"efs_save_for_sgsII.tar"
"efs_save_for_sgsII.tar.gz"
"nv_data.bin"
"nv_data.bin.unlocked"
JUST TO CONFUSE THINGS EVEN MORE I have just found 2 more files on sd card called " efs.img" and efs.tar.gz"
GALAXY I9100, GINGERBREAD XWKI4, 2.3.4 BASEBAND VERSION UNKNOWN, BLANK IMEI
Any help appreciated !!

First and Foremost you are posting this in the wrong forum, so not many can advise you about it, ( will ask MOD to move you to S2 Forum)
But not to worry as long as you have so many backups, you can use them to overwrite your current efs folder or use restore function in S2 Repair and restore the backup. Just for your guidance read this
In fact KIES will auto repair this problem, when you connect to it for updates as ( in most cases) 2.3.4 is old firmwares and have further updates.

Hi
Thanks for the reply and I am sorry for posting in the wrong place.
I did use S2 repair at first and it worked. I also unlocked to tesco PAYG using Galaxy S Unlock. When i did software update and it went blank again S2 repair did not work ?? After reading about efs back up I am worried that if i keep trying s2 repair the old files might be lost forever ??
I am not sure what method to take next !! with been a noob and all !!

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.
Solution
I managed a solution to get your phone back, not perfect but works.

Send me a PM for the EFS partion backup link.
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.
Hi, I'm new to rooting etc. Is it too late to backup an efs folder after I rooted the phone but have done nothing else?

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..

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,
I know there's a lot of post about the topic already, but so far I haven't seen anyone on Galaxy S III.
I haven't had the chance to root my phone yet when the problem occurred so no efs back up. It just suddenly stopped working. I read somewhere that it may have been corrupted because of the pattern lock which I was using but I don't really have any evidence for that.
I tried everything mentioned in S II forums except for GSII_Repair since its only for GS II. I tried the recommended copy the nv_data.bin to the sdcard. delete the original and copy it back again but the nv.log is telling me that MD5 has failed and it just keeps replacing the nv_data.bin with the default.
I already went to the service center and they will replace the phone in about two weeks but I just wanted to check with you guys if anyone else have experienced this on S III. And if ever kindly give advice on how to not get this problem again hehe.
no one experienced it yet?
Its not a standard fault so i would not expect posts . Rooting or flashing may break the EFS folder hence the number one recommend to back up EFS folder before flashing .

Hi guys,
I have searched high and low for this issue. I have found a lot of forums on how to fix the problem but none of them pertain to my circumstances. I installed Omega ICS ROM v 13.1 a week or two ago. I then decided to install Omega JB v18. I then upgraded to Omega JB v21 as well. In preparation for the official Samsung JB ROM, I went back to ICS. I started by downgrading to Omega v13.1 ICS followed by stock Samsung ICS ROM I9300XXALE8. A couple of days after doing this, all of a sudden, whilst on a call, I lost signal and then the stop sign icon appeared in the top toolbar. I have no radio, no wifi, no bluetooth and no lock screen & power menu. After all of the reading I have done, I have managed to discover that my EFS has disappeared. I have rooted the phone and installed ES File explorer and have looked inside the EFS folder only to find that it is blank. I did have a Nandbackup but managed to delete it in my attempts to recover my phone (yes I know im stupid but I didnt realise the significance of the backup until I realised what was missing!!). So, no EFS backup. Seemingly nothing in the EFS folder on the phones root. Any help would be greatly appreciated. One thing I did notice, which I am sure is significant in some way, is that when I put Omega JB on it, my sdcard mounted as "sdcard0" or something along those lines. Again, because I am fairly new to the custom ROM world, I didnt realise the significance of this until I had down graded back to ICS.
Please help!!!!
Thanks again.

If you do not have backup of efs folder. You have no chance of getting imei back.
You can go to service centre for rebuilding efs folder.

Flashing any roms can destroy the EFS thats why its always rule one to backup EFS folder . Multiple flashing up down up down increases the risk .
Did not Omega backup your EFS .
You say
have no radio, no wifi, no bluetooth and no lock screen & power menu
Thats not the signs of IMEI corruption as it plays no part in power menu or lockscreen .

I think that S3 has some problem in securing it's EFS folder.
I flashed my S2 with hundred's of roms and never faced this issue.
Secondly in my experience lock screen and power menu is efs folder issue.

Read all the SGS2 and one help IMEI /EFS posts i suggest .
lock screen and power menu is efs folder issue >>> If it was a continual factor in the posts regarding EFS/IMEI then i would have agreed .

A reminder about 2 things:
1) swapping/changing/etc IMEI's is illegal
2) giving someone else your EFS folder wont work, your phone will just default to the generic IMEI which is normally no better.

I wouldn't do that : in gs3 efs is not in the same block as gs2. It'll be worse than before.
Send me your efs partition backup using efs backup pro. I'll tell you if something can be done or not to restore your data.

Hey. This is one of the things I had read about and tried and it came back with nothing. I don't recall the error message but I think it said it couldn't find the partition or folder or something. I am certain that it has to do with Omega Jb and the fact that it installed and mounted sdcard as sdcard0 and somehow, when going back to omega ics, this has occurred. Another thing I have just now remembered is that I had also setup a swap partition on my ext sdcard and had it mounted. This was all working fine for a few days though so I don't see how that caused it. Was really odd. Anyways, thanks for all the help, but I am going to pay for it to be repaired.

I also lost my IMEI no after a flashing a rom, as far as I was aware I had never made a backup of my efs folder, I attempted many different methods to resolve this, then I checked my external SD storage and saw an EFS_BACKUP folder with numerous compressed EFS files, I simply selected one of the early ones copied to my desktop and extracted contents and used them to replace my current efs folder on root of the phone, then reboot and you should have your original IMEI and phone working again, hope this helps goodluck
Hi guys
I bought samsung galaxy s3 i9300 sprint and it was working with me pretty good until i installed a new customed rom , and rom was working fine and one day i have lost my mind and wanted to increase the ram so i downloaded an app after i rooted my phone and instead i format the sd card parition i have formatted the efs and my phone doesnt boot , was freezing on the startup so i Google and found out to download efs repair and after it worked fine but i cant make any calls it gives me a fake IMEI , i installed new official rom 4.1 and 4.3 and changed too many modems all kinds of modems i think but nothing worked and my IMEI still not restored to the orginial one that is written on the back of my phone .
i noticed later that whatever i install from modems it is like nothing because efs folder in my phone missing the the file that my IMEI stored in so i got later that the file that store my original IMEI is missing from ESF folder
I also tried everystep about busybox and emulator dos and nothing worked with me because i think i need to rewrite again my IMEI .
Is there any means to do that or anyone upload me EFS folder of same phone or i will just throw my phone now i dont know what to do i havent enjoy my phone more than one month
Wrong phone, wrong forum. This is for the i9300 only.
If you've wiped your efs then nothing you can do, take it to a repair centre and pay them to fix it.
Questions go in the q&a section, not general.
I cannot help here, but i suggest having a more specific title for the topic.
thanks!

Theres no way to fix it unless u have a back up of ur efs. And yeah. this forum is for the international version not the sprint version. Go to the repair center and ask them to fix it for u. You most probably formatted ur internal memory since its called the sdcard. ur ext sd card is called the sdcard1

Local shop will fix this a lot cheaper than Sammy service center. Efs is not located on int SD so wiping int SD won't wipe you're efs. Any back ups you made to int SD would be wiped.
