Hello, today I got a live demo unit from Samsung, but it's a small problem, in this device, it is not possible to use the phone part, it is possible to fix this? phone is not locked, and the sim card is in working, and all apn is i order, but it wont register on the network.
NEW INFO!
My phone is "out of service" and i cant turn it on, so i can use it.. can some one please help me.
the raido is working, becasue WIfi is working, the same with thew bluetooth, so it seems to be loocked for use of sim cards.
please help me some one?
my imei is a very strange imei starts with 00499................
Hello Jespersen84. Seems like i9300 live demo units don't have their own IMEI (they all have the same) and the EFS folder isn't complete, some files are missing.
You can use everything, except phone calls, sms, mms and 3G data.
Thats correct,
but i was hoping it can be fixed, maybe change imei, or is it possible to copy the files that are missing to the efs folder?
i have tried to root it, i have installed new custom rom, nothing wil work, i thing i have to cange the IMEI to get it to work.

Change IMEI is illegal and against XDA rules .

Closed, as changing, and discussion changing IMEIs is illegal, and against XDA rules.
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 there.
Hope someone can guide me on this. I've been reading all the posts related to unknown imei, lost efs folder, etc and tried several things to solve the problem, but anything worked out.
The phone got wet with some raindrops (very few raindrops). Warranty was lost because they told me the motherboard was damaged by water. At first the battery exhausted in no time and it didn't charged properly, but a couple of months later everything seems to be all right except that it tells there's no IMEI, and the SIM card isn't read by the phone. Later on I've brought it to another technical service where they've told me the motherboard wasn't damaged, but the SIM connector. They wanted me to pay a big amount of euros for such a little piece. I picked up the phone and decided to investigate by myself.
The actions done to the phone: I fisically opened it and applied a connector cleaning spray; then I upgraded it to ICS and finally rooted it. Then I tried lots of solutions that are posted in the forum, like the GSII_repair, busybox, backup of the efs folder via android-sdk, efs pro, etc.
The only thing about efs that I can read in the phone are two files: an efs.tar.gz and an efs.img.
The efs.tar.gz seems to contain everything needed to restore EFS folder: nv_data.bin, nv_data.bin.md5, etc.
I have no idea how to tidy all this mess up. I know that it's possible that the phone won't work again because of the rain, but I want to sold all the possibilities out before using it only as an ipod galaxy, and I resist thinking that if it was damaged by water the phone woulnd't work ok like it does.
What do I want? Trying to give it its IMEI number again and seeing whether it catches signal. Any idea on how to do that with the files efs.tar or efs.img.
Thank you so much.
Since you have some kind of an EFS backup, then you can use kTool, in the Google Play Store, to restore that backup.
kTool requires root.
Hi and thank you for the reply.
I've downloaded this hc-ktool and tried to restore EFS from backup via efs.tar.gz and via efs.img but anyone worked out. It still says "unknown IMEI". Any idea about why it didn't work?

In the baseband section it tells UNKNOWN, as well as the telephone number, IMEI, IMEISW and Bluetooth. D'you think changing the modem will change all the other unknown stuff? I'll try it anyway, thanks.

Nothing to do with the modem. I changed it and everything's still the same.
Still rounding the problem... I installed root explorer and I saw there is an original efs folder in the root of the memory, not in the internal sdcard of the phone. So, what can the problem be? Is the phone really damaged? Or do someone think is only a software matter (is the efs folder corrupted?). Anyone can help?
http://forum.gsmhosting.com/vbb/f258/galaxy-s6-edge-imei-null-null-1960154/
So this morning I woke up and i couldn't get on my carrier network.. Which made me wonder wtf was going on. So I tried to go into settings to connect, but it wouldn't let me. I then realized my IMEI number was "unknown" which made my face one huge questionmark. I've tried using this guide; http://forum.xda-developers.com/showthread.php?t=1264021
But I can't find my folder? BUT!!! I found a EFS backup on my internal sd card.. which is good. I just don't know how to use it now?
I have CM 10 Nightly built from about the 15th of December (2012) and Siyah kernel... I think..
The folder i'm talking about is a zip named efsbackup.tar.gz
Can anyone help me? I tried going back to an old backup I had from october, but it didnt work either..
Try using an app like kTool (there are others) to restore the EFS backup (but obviously you only want to try this if it's definitely borked). There's a thread devoted to it on here (and you can get it from Google Play) which should have instructions on how to restore with it (never had to restore one myself).
The backup would have come from Siyah, which automatically makes an EFS backup. If you manage to fix it, thank Gokhan

I downloaded the app just before I saw your comment.. and it all looks confusing, but I tried clicking the "Restore EFS from backup (DANGEROUS" and it says I don't have the files.. Is there a way I can browse into my internal SD card, choose the file and then restore it?

I did say "There's a thread devoted to it on here..." (kTool). I would have thought that would be a pretty big hint to read that thread from start to finish if necessary (it's not a big thread; 23 pages. Can flick through it in no time).
And as I've never had to restore EFS myself, I only know what I've read in threads on here (same as you) so can't offer you first-hand experience. I figure the answer will be in one of the threads devoted to restoring EFS (and there are heaps of them on here), up to you to find it.

Its not a good combination when im tired and I really want to fix my phone.. But I see lots of issues.. The only thing is, I didn't have a EFS file when I looked ( I hooked my computer up, but i dont have an .etc map?) so..

Well I've given this a few gos on myself, and I've tried several apps claiming to be able to fix this, which made a EFS folder or file, and then it restored the exact folder again.. But this is all I got. I got a IMEI number, but it's a fake one.. or standard one, either way, it is not mine and not acceptable to any carrier. When I dial that it says "Not registred on network"

yeah, you've got a generic IMEI. Did you look under the battery? there's your REAL IMEI.
Still, dial *#06# and tell me what number pops up.
In that case, leave it till you're not tired. Last thing you want to do is do something silly & bork your phone. It can wait.

Well, you got a couple of guides to use those apps.
First of all get try locating the efs back up with root explorer app, so you can move it to a folder where hc ktool can restore it.
If that doesn't work get busybox running in the background and open gsii repair.
and if all the above don't work, your up for reading threads time.

Hi guys I'm having a strange problem with my sister's galaxy s2. For the second time she lost her IMEI without any reason (no flash ecc just turned off the phone and no IMEI when turned on). The last time I've been able to restore it and I made all the backups using efs pro, But this time when I try to restore it the procedure goes well but the imei is still missing. I tried to restore it manually and I discovered that for some reason the EFS folder is blocked on READ ONLY and I can't switch it in R/W. This problem is preventing me to restore the IMEI and I can't find any similar case on google. Can someone helps me with it?
Thank you a lot

Sure the phone is rooted. My situation is very strage. If I enter the EFS folder with root explorer and I click on "Convert to R/W" the folder remains R/O. Also if I try to cancel any file (or rename or move) in EFS folder nothing happes (that probabbly is what prevents EFS PRO from working). Is there any way to force that folder to be read/write or to cancel it? Maybe using adb shell from the pc?

Eheh of course I already done it about one year ago! The problem was my blocked EFS folder but now I know how to fix it if it happens again :good:
People seem to have problems whenever they use EFS Pro. People should use kTool; seems to almost always restore without any problems.
