Hello Guys,
I have an 8 month old i9100 that never had a custom rom or even root, but for more than a week los it's baseband information/IMEI and all the rest. The EFS folder was intact, no file missing and I tried all the known restore methods of restoring the IMEI but with no succes.
My question is: can it be a hardware problem? The service said the board need replacement. I have to mention that the phone had some serios drops in it's lifetime, but non of them when this problem occured.
I need some advices...
Thank you!
hardware prblm cause no root,custum roms,or changes,tweaks u made ..but phone had serious drops u say...so the board mus b damaged..do u hav efs bckup,if yes then root an restore using helcats tool..

It's not my phone and I had to use the EFS folder I found. I tried with other nv_data.bin files but no result. is like phone refuses to read the file. No previous EFS backup as the user of the phone has no idea about custom FW and stuff like that... he uses what he buys.
go in efs and delete nv data.bin and nv data.bin md5 an there is a imei folder u can delete and replace with the backdup efs.....but sure u hav the good efs bckup or the phone is fu---ed up

already did everything I could... nothing seems to work. Also, afik if you delete the efs folder, the system creates another one with nv_data.bin inside, ofcourse not a good one. In reality, in this phone if I delete the efs, at reboot it gets recreated but with no nv_data.bin inside...weird
Wow M8! I just posted a question regarding a GS2 i bought from a friend with the exact same problem. If you find something let me know, If i do ill let you know then. But i guess its not because of the drops the phone has taken because the one i bought is intact. But exact same issue here....

Hello all!
I guess the APP Chainfire broken my IMEI, i already changed my rom and nothing happen.
When i did #*06# my IMEI is 0000000000000
reading some tutorials I saw that I need to back up the EFS folder but this folder does not exist!
What can I do to restore my imei?
If someone pass me the backup of the EFS folders I use it?
You're basically screwed and you need to send it for service
This was sent from a Galaxy Ace. Problem?
Aw! Thank anyway!!!: (
At times flashing a stock rom and not a custom one might help... and data abt imei stored in efs folder... so i feel no one wud share his efs folder with u... and in the future do use an app named nitrality for making a copy of ur efs folder...

Good luck trying to back up ace's imei and at the same time doesnt messed it up and lose it forever.
See the irony? U wanna back it up and in the process u actually ****ed it up.
Why would backing up something ruin it?
Sent from my GT-S5830 using xda premium
Because it wasnt a folder to begin with. Its a hidden partition that intentionally left unmounted on boot. In order to backup it u need to see it, in order too see it u need to mount it. This when disaster strike. Forget to unmount it and it'll be lost forever. And even if u do manage to back it up its still useless because theres still no known method to use it to recover ace's imei. this have been said many, many times before, yet u who is a senior member with over 300 post still clueless. Thats what amaze me the most :/

Hi everyone! I know i'm not the first one who has this problem but i'm one of them.
I read and tried everything on what i could find about this, but i can't get it fixed! please help!
The situation:
I have a I9100 Galaxy S2, and it works fine, except for the cell phone functionality. It sais "Baseband unknown", has no imei number (also no 0049... imei), and i tried multiple EFS folders (i also have one from a friend who got it from his own Galaxy S2.). But no work.
In fact, i read that if you delete the EFS folder, it should autocreate a new one. It kinda did, but it only generates a bluetooth, upgaddr and wifi folder. Nothing more nothing less.
I flashed another rom, i flashed another phone image with Odin. I tried to erase all kinds of stuff with the clockwordmod recovery. But nothing helps so far.
If i'm correct from my standing, it looks like the baseband is broken itself. Why else wouldn't it even recreate the EFS folder? I'm starting to think that my original EFS folder (which i backed up before replacing it) was fine, but it's not even being read anymore...
Can anyone help me?
Thank you!
bump, still trying. Flashed a new clockworkmod recovery and with adb reformatted the efs partition as listed on xda somewhere. Then rebooted.
The Bluetooth does get a new mac address, so that part is good, but baseband still unknown and imei totally empty.
Also, the phone should regenerate the efs folder itself right? Well it doesn't. That means, it makes a bluetooth and a wifi folder, but that's it. No files or whatever...
Help please!!
m8 y u even delete the efs folder????? anywayz u got a backup so jus copy papte the files of efs...an flash stock rom....if u get un known base band then revert one step back --tht is flash a stock rom then come to present rom--then check///or u can flash cwm modems available suited to tht rom...but make sure u r pure stock--pda,modem,csc.....an yes copy the good efs folder on ext sd card too ,,so tht u can set same permissions like the ones ur copying to phone efs folder(sometimes the permissions change afta reboot)
i'm facing the same problem
hello, i have a question, in galaxy is recomended that make a bkack up of efs folder, for IMEI, is the same in WT19i?, and if it is, where is the folder with IMEI number thz.
Why would one need to backup IMEI?
Doesn't matter what you do with your phone, it won't change. The IMEI is written deep in the system(not in /system or ROM, even deeper). Where exactly, we don't know.
Can't remember, how was that file system called...
IMEI
hello thz, i see Galaxy s2 have a folder called efs where is the imei, and in some cases it cant damage and you lost it, for that reson thery recomended backup it, THZ

Sorry to inform that,IMEI on samsung phones gets messed up very easily.Flash 2/3 custom roms and you'll probably end with a generic IMEI.I had a galaxy SII with generic imei.I tried a lot to recover the imei.But as i didn't have the backup of "EFS" folder,I was unable to restore it.Now using a xperia mini pro.Don't know if phones from sony has these kinds of problem or not...!! Searching....!!
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.

Thanks guys...I have tried this one. Didnt work. Just wondering if anyone knows how or if I might be able to restore from sdcard0, if it still exists. I assume not, but I guess it might be something. Does anyone know why Omega JB did that in the first place ?

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.

Imei NULL/NULL - EFS Folder Lost.
Hi, I have a i9300 which lost efs folder, already tried restoring it through the box octopus, but at the time of writing the imei, it reports the error. (Write imei fail). Anyone have any idea what I can do?
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.

Efs I learned a lot about on the s2. S2 and s3 and all Sammy phone work the efs the same. What's nv_data.bin file size. The PIC is to show that efs folder isn't in int SD. Any efs file that's in int SD is a copy and same as with ext SD.
Also try this out...
http://forum.xda-developers.com/galaxy-s2/help/solved-stuck-flight-mode-efs-issue-t1261948 may help may not but its worth a go on the s3. There also is a man on xda who can fix efs...all he needs is control of you're PC to make it happen but he charges for this. Interested? Not been interested in efs folder since s2 but now I'm getting interested again.
