Hi all,
In a bit of a pickle. I have flashed many phones, and this time I obviously didn't do enough homework.
What I did:
My S3 keeps losing data intermittently, so I thought having done this to a Razr, SGH-T809, G1, etc - I'd flash the latest OS - 4.2.2 (i9300xxufme7)
I downloaded Odin and installed CF-Auto-Root-m0-m0xx-gti9300
I then used Odin and flashed i9300xxufme7
I then was happy as larry, at how simple the process was - however, it turns out I now have an IMEI of 00499 and no phone number.
I am on T-Mobile UK, however the phone was purchased through a reseller (Mobiles.co.uk) so I'm not sure if it's a T-mobile phone, or a vanilla S3 that they supplied. I have never tried a different Sim card in it. It may well be locked.
What I have tried to do:
Re-flash to the standard 4.1.2 image which I thought was I9300XXEMG4_I9300OXAEMG4_BTU (this is I believe the UK image) - no change
Used NV Read write - I put my phone in RNDIS + DM + MODEM but the device isn't recognised.
Just wondering what my options are at this point?
Thanks.
Darren.
As per thousands of identical posts .
Restore your backed up EFS folder .
Fail to backup EFS then its a paid for service centre job .

Yeah, I have read this advice but I could only see it mentioned in posts from August - and since then found tools such as NV Read write, so wasn't sure if that was still the way.
I am going to try and flash TMU-I9300 to see if that will help in the first instance.
I also read that backing up the EFS folder is part of the installing ROM process by default, so could there be an EFS Backup made automatically?
Thanks for your quick reply. I'm surprised I never read the EFS backup procedure whilst doing my home work (for example, it's not written on the Sam mobile guide I followed).

Yes some custom roms backup if you choose EFS backup . It is EFSbackup tar file .
'm surprised I never read the EFS backup procedure whilst doing my home work (for example, it's not written on the Sam mobile guide I followed).
Its plastered all over the forum from week one .

Okay so because I didn't flash a custom ROM per say, no efs backup would have occured?
And I didn't read from week 1, this phone is almost 2 years old - I read the most up to date information and a step by step guide on sam mobile. Hind sight is a great thing, you obviously have it in bundles!
Well if we ignore retrospect for now and just concentrate on moving forward; you need to send for repair. I'm sure lessons have been learnt and efs backups taken before flashing next 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.

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 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.

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.

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?
I know many people have already asked about their IMEI disappearing and i managed to restore my backup using Galaxy Toolbox before but i tried to restore my IMEI again and it didn't work. I then decided to revert back to stock via Odin and i successfully went back to a stock ROM but my IMEI is still missing and i am getting quite worried now. Have i lost it for good? I obviously lost it after flashing the data2sd-ext script by Amarullz if this helps towards helping me?!

I managed to finally restore my IMEI. It was very confusing but basically i had to delete the old directory/folder i had on my ext-SD and then download Galaxy Toolbox. Then i opened up the app and went to the restore option, it says it could not find the directory and tells you to make one with the backup i previously took beforehand when i had a working IMEI. So i connected my device, transferred the file into a new directory named 'GalaxyToolbox' and disconnected the device. Finally i loaded the app and restored my backup, rebooted and hooraaay my IMEI was back!! I can't tell you how relieved i am! I MUST donate to Doky for making such an amazing app! I think i'm going to leave the data2SD-ext script for now and maybe try other methods if there is any?

what is the name of the "old directory/folder" and where do I find it? I really need to resolve this problem
I probably didn't explain my solution very well after reading back through my post.
It has been a long time since I faced this issue but I'll try and explain what I did to resolve the problem...
1) Connect your device to your computer and transfer the GalaxyToolbox folder (should contain 2 files inside) to your computer.
2) Delete the GalaxyToolbox folder on your device once you have transferred it to your computer.
3) Disconnect your device and open File Manager/Explorer app on your device.
4) Create a new folder titled 'GalaxyToolbox' with no spaces on the root of your SD Card.
5) Connect your device to your computer again and transfer only the file titled 'EFSpart.img.SAVE' to the new GalaxyToolbox folder you created on the root of your SD Card.
6) Disconnect your device and let media scanner finish. Open the Galaxy Toolbox app and select restore EFS partition. It will tell you it has found a backup and ask if you wish to restore it, click yes.
7) Close the Galaxy Toolbox app and restart your device.
Type *#06# into your dialer and you should see a small box pop-up with your IMEI number letting you know the restore was successful.
I know it seems strange that this method fixed it for me but I think the app itself creates a 'temporary' backup which is the backup of your currently missing IMEI number and when you try and restore it keeps restoring the EFS backup which has no IMEI... So starting from fresh and moving the original backup I made back into the GalaxyToolbox folder seemed to have fixed it for me.

What if someone doesnt want data to be restored. Of course it was an option when we had no way of backing up IMEI
But now (for over a year), we can work on IMEI independently via Galaxy Tools, then what is the need of this method handling data and it also can cause many FC's
Yeh Bro. Its Just. If They Dont Want Data To Be Restore Just Flash De Stock Firmware. Ur Rite.

I agree, if you managed to backup your EFS partition via Galaxy Toolbox beforehand and you are facing an issue with your backup not restoring as it should then follow my mini guide on the first page of this thread. If however you didn't take a backup before you lost your IMEI then you'll have to follow the guide from this link -

I've been trying to backup my EFS folder from my US Cellular GS3 (SCH-R530U) with very little luck. A couple hours of searching has pretty much everybody recommending the use of EFS Professional, so I grabbed that (release version 2.0.26), Problem is that it crashes after initializing the ADB server, hitting me with event name "CLR20r3". Searches to troubleshoot that error suggest that I check to make sure my .NET Framework is up-to-date and that I don't have any other ADB processes running in the background. Both of those have been done; error still pops up.
As-of-yet the phone is unrooted; I've been trying to backup the EFS before I begin a root and subsequent flash to AOKP (for starters). Does an unrooted R530U have issues backing up the EFS folder? Any ideas on how to fix the error EFS Pro is hitting me with, or alternative EFS backup options?
Many thanks in advance.
Are you asking in the right forum? Anything you try or download from here can kill your phone.

Was going to post in the developer's forum for EFS Pro, but don't have posting rights. So posting here on the off-chance somebody has an idea or an alternative.

I'd suggest a start from some modern recovery f.e. PhilZ Touch or CWM 6.0.3, both of them have very nice feature of making a backup, including your /efs folder. Then you can flash original stock recovery if you wish or simply flash any ROM you want because custom recovery is everything you need.

Hey everyone,
I recently flashed a ROM on my girlfriend's phone and due to an issue with the messaging app not working I decided to flash the ROM on top (the ROM had an option within the Aroma installer to change the messaging app whilst removing the previous one).
When I rebooted the device I realised that the phone had no signal. I checked the thread and found that the fix was to flash the same ROM again, wiping data, etc but to choose a different modem.
That didn't help so after searching some more on the thread people were mentioning that I should restore the EFS. I had made a backup previously so I used to restore the EFS using EFS Pro.
Upon a reboot I discovered that the IMEI had changed to 004999010640000 and the phone can only make emergency calls.
I have checked many threads regarding the changed IMEI and I have tried many of the fixes but to no avail. I have fully restored the phone to stock, tried many different modems and have tried restoring the EFS using different methods.
Does anyone have any ideas regarding any further methods I could attempt to restore the IMEI?
Thank you.

Follow the link in my signature to general sticky roll-up. Then read "Imei / efs - know this stuff". This includes everything you can do and the last option is send for repair. If you have already tried everything in that thread, send for repair.

Some people say to try to extract efs folder
Delete content of the existing one and copy paste the backup onto the folder and reboot solved their issues

I had attempted that previously, but thank you for the advice.

Thank you so much! After reading the sticky (apologies for not viewing it before but I wasn't aware of it's existence), I found out what the issue was and sorted it out within minutes.
For others that might have the same issue as me, when I restored the EFS backup I did actually solve the issue, the problem was that I was on the wrong baseband due to when I restored to stock.
Flashing the Aroma baseband package (which can be found in the sticky) after restoring my EFS backup resolved the problem.
After reading the sticky (apologies for not viewing it before but I wasn't aware of it's existence),
Was that due to it being hidden or some other problem .
Its no good us telling users to read the basics if they cannot find them .

Tried with a few phones and currently my S3 does not work. Been trying all the fixes (u name it i ve tried) last 2 days, driving me mad, my phones goes from 000049 imei to original( serial no.intact) depending on which modem i flash it still don't connect to my network.Was able to save my Note 2 in one go. Why is it that only Samsung phones have this problem, SDS, lost of imei etc, still think the best phone to play around with is LG ( can purposely brick the phone n revive it :laugh tho its not very popular. My fav is still HTC
