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.. I was confused, but then I saw the backups and immediately backed them up AGAIN... Hmm. And I can't factory reset, can I?

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.

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?

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.

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..
samsung galaxy note 2 lte 4g N7105
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 guys,
Right so I own both Galaxy SII(personal), GT-S5830(business) and my wife has a GT-S5830. Located in the UK
Now I have been looking at the latest CyanogenMod and would like to install this ROM on my GT-S5830, as I understand this is one of the best custom ROM's available for this phone.
However every where I read advises me to first backup my /efs folder, only problem is I can't find this folder to back it up! So far I have tried EFS Pro and a few others, but they all fail or give me an empty folder.
Any help would be very much appreciated as I have been researching this since Friday and I'm pretty much ready to blow a gasket....

I thick it has something to do with IMEI coz some guys r loosing their IMEI after flushing custom Roms which results to no signal situation meaning ua phone is done 4 real coz there is no known way of recovering it 4 Our ace
I keep reading that it is wise to back up this folder before you start flashing new ROM in case you screw this folder up.
U read that on other device forum, not here on ace forum. As i said earlier, dont ever touch ace's efs partition.
But if u insist of doing so, theres a thread here somewhere guiding howto network unlock ace, and in the process also explain howto mount that particular hidden partition. May god be with u if u ever try to do it.

Don't listen to anybody who says to leave the efs alone. I don't have your device but I STRONGLY urge you to find a way to back up that file. If you have already rooted the phone then a good file explorer should allow you to make a copy and send it to dropbox or save it to your external SD. Even mass storage and copy/paste it to your hard drive on your computer. And yes... CyanogenMod is the very best.
Good luck!

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.

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 .

2) giving someone else your EFS folder wont work, your phone will just default to the generic IMEI which is normally no better.

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.

So you were restoring nandroid backup and you lost your phone's IMEI? No never happened to me. But you should have made a backup for it dude!
Edit: Okay got it. Install Root Explorer pro and check whether the efs folder is there or not. Set the same permissions from another I9100 and then reboot. Set the same permissions for each file in that folder and the folder itself. If you have made a backup in the form of .tar file then use HC ktool to restore your efs folder. It would automatically set the permissions required!

no thats not what happened. I rooted my 4.0.4 using Odin and Siyah Kernel v5. Straight after rooting it, i downloaded GSII_repair from the app store and backed up my efs. Then i downloaded Titanium and backed up everything. Then i went to recovery mode and made a back up. I finally flashed the Resurrection ROM v3.1.3, i rebooted, everything was working fine, like imei was there and so was signal, i restarted my phone and my imei number went away, so i used the GSII_repair app to restore, it worked fine. I restarted my phone again, imei was gone yet again. So i decided to go back to my stock ROM back up, imei was gone, i restored, everything working fine now. Just not sure whats happening because i have rooted phones before and that has never happened to me, every time i restart, imei goes away, sometimes it comes back, sometimes it doesnt. What has happened? just reallly confused. i have a back up of my EFS though.

Oh man that is really heart wrenching. Atleast you made a backup before messing with your phone. Okay now can you restore your efs? If yes then restore it and download HC ktool and make another backup for it. Then restart your phone and if you lose it again then restore it using HC ktool. You can try EFS Pro from your PC as well.

They are two different tools I guess for efs backup and restore. HC ktool can also make backup for your kernel that your are currently on!

just restarted my phone and checked, the imei number is showing. i didnt have to restore or anything. Is it safe to flash a ROM now? or any risk of brick? thanks for your help btw
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

I get your point but with your IMEI coming and going, it would point too corrupt efs files on the root of your phone, given you have tried various methods already, I would take a copy of the suspected corrupt efs folder save it onto your pc, then go back to the root folder and delete it, replacing it with one from your EFS_backup folder on your external SD, no need to edit any of the internal files or use any other software, simply reboot

But do note down the permissions of the folder. You will need to set the same after pasting. Use Root Explorer for replacement purpose.

i have root access and everything but it wont let me delete the efs folder, keeps saying its only readable...
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

Have you root your phone?

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?
try tool, play with it for a while.
GS2 repair app is your other choice.

Thank you a lot gastonw that worked. If someone is interested I had to cancel the efs folder with hc ktool, reboot, restore and reebot again to have i work. Now I think that I will upgrade the phone to the last firmware available hoping to avoid other imei loss

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.
This is the new ROM Manager?
