Actually the last time I tried to restore I had the same issue. Not sure what the remedy is, but I had to just re-flash the Modaco ROM I was running prior to trying out the 2.1 Rom. Wish I knew what was going on.
just figured it out...let me ask you this did you rename your nandroid backups?

No, I just have a ton of them in my nandroid folder but never changed any names.
It names the backup based on the source device serial number and the time the backup was made. This, I think, is how it knows which one is the latest. I had this problem once before and the trick was to create the following folder structure in the root directory of your sd card:
nandroid\[insert device serial number]\BCDMRS-20100205-2102\
Note the BCDMRS-20100205-2102 is just a folder name I took from my nandroid folder. If you created the nandroid folder as I describe and have just one backup you can use the same folder name I did and put your backup in it.
An alternative method would be to do a nandroid backup to recreate the paths on your sdcard and overwrite the contents of your equivalent of BCDMRS-20100205-2102 with your older backup.
I didn't get much sleep so sorry if this doesn't make sense.

Cool i will try that and see if it works. Actually im not all that pressed to backup any of my nandroids, so if this doesn't work I am going to delete all of mine and make just one backup to what im running now and hopefully that one will work if I ever need to restore. But thanks for the info.
You posted as I was editing my post. The alternate method might work better.
yea i just renamed my nandroid backups to the date in which i created them ie. 20100303 and that worked...weird i think but it works like a charm
As a lot of you will know a few Nexus S owners have had problems with there IMEI numbers being corrupted/re-written after flashing a ROM from on here (XDA) no blame being apportioned at all ! We all know the risks of flashing ROM;s, Kernels, Radio's etc.. And we do this entirely at our own risk.
However a fix is still needed, although more and more people are returning there phones under warranty.
I'm one of the lucky ones who sent there Nexus's of to cpw and who's had there Nexus repaied and returned.
Back to what I need help with.
What I want/need to do now is back up my efs folder, so that I can restore it if anything like this was to happen again,.
Is just backing the folder up with Root Explorer, Astro or a simular App, saving it and then just restoring it enough, Is it that simple? The reason I ask is that when Ive backed them up, I then check the Details and they differ.
The efs folder on the phone / is 4,214,784 bytes and contains 7 files.
The backed up efs folder on the phone /mnt/sdcard is 4,227,072 bytes and contains 10 files
Whats that all about ????.
Can anyone recommend an App thats spercificaly for this task?
Sugestions welcome
Thanks in Advance

Have you tried this and compared folder size's and how many files in each folder ?
Also, what about backing up RSA keys?

Hello Everyone.
So... I'll get right to the point here. My Galaxy S5 got stuck in factory mode. That day i was installing a bunch of ROMS. If you need a list of them, let me know.
I decided to go back to my old nandroid backup because I wanted to wait for a 4.4.4 version of the ROM i had found. However, I also got interested in installing a Custom Kernel, so I went ahead and installing Chronik Kernel cause I heard that it was really good. However, I forgot to wipe the cache and dalvik cache before installing the zip, so now I think it messed up my EFS partition, and am stuck in factory mode without WiFi and calling.
I have tried many methods involving the "FactoryApp" folder, but when I checked my phone to edit the text, the folder wasn't in the EFS folder. So I also knew that the Terminal Emulator option was out.
I even tried unrooting and re-installing the stock firmware and doing a factory reset, (I have a nandroid backup on computer) but even that didn't work. I can re-root if needed, but please someone help me, I really want to fix my phone soon. (Also I probably shouldn't have tried doing this on my vacation from home, oh well I am a really curious guy)
Help please!!
Someone please help me! I really don't know what to do! All that is in my EFS Folder is a bunch of APK files for apps i have installed and these files called: act_lock, react_lock and react.lock.bak. Someone please... I really want to get back on WiFi, also I am back from vacation, so I can use my Data plan to install things needed.
Is anyone going to help me?

Typically it is in a file efs/FactoryApp/factorymode.
Can you show your efs folder structure?

It looks like you have an invalid efs folder.
Did you make the imei backup? If so just restore it.
If you don't have imei backup, try reflashing full stock firmware.

Yes, it is not too weird as Samsung now does not store the IMEI in EFS partition. It does store in another 2-3 partitions (these partitions are vary from model to model).
EFS partition does not contain the IMEI. It contain the S/N, WiFi and Bluetooth MAC addresses, etc...
Please do the following things:
1- Install Phone INFO ★Samsung★ app and look for the IMEI and S/N (in the DEVICE ID section), and compare them with the IMEI and S/N on the sticker behind the battery. Are they the same?
2- Create a file with a name 'factorymode' on the sdcard, open it, input 'ON' and then save it. Navigate to the efs folder, create the folder with a name 'FactoryApp' (case sensitive). Finally move the file 'factorymode' you have created above to that folder. Reboot the phone to see if the problem still persists?

Alright so the imei is the same but serial number isnt, however when I try to create folder it will say in efs partition: Operation failed:No Space Left On Device

Yes, as I have said, the efs folder does not contain the imei. However it does contain the S/N.
What did you mean by 'serial number isnt'? The S/N in Phone INFO app is still in valid format? Or it is zero or empty? Can you PM me that S/N (in Phone INFO app)?
Regarding creating folder, make sure your file explorer app has been grant root permission. And try to move/delete some APK files (in efs folder) to free space.

i still have the same problem did evry thing but didn't work for me :S
As I see often people having problems after flashing roms, I noticed that they always forgot one important thing to backup.
So I decide to write this article about the importants of the EFS as it is your lifeline of your phone.
Maybe you already have heard of the EFS partition, if not then keep on reading.
The EFS is a partition where the most important device infromation like Wi-Fi address, Bluetooth MAC address, IMEI address, etc is stored.
Without this data, you won’t be able to use your phone anymore and it's completely bricked.
So It’s extremely important to keep a local copy of your EFS partition as when the EFS is damaged then your phone has become useless and can only be restored with your personal EFS file.
You can't use an EFS file from somebody else as the file is your personal acces code to your hardware.
Hopefully you will never have to restore your EFS partition.
However, it’s never a bad idea to make a backup copy, especially if you flash allot of roms like I do.
Thanks to xenon92 for the APK version.
Thanks to lyriquidperfection for the window version

I don't understand the question.
Technical you might never need it, but it's just incase something went wrong.
i have flashed my phone already hundred of times and it always went okay.
If you use the tool from Xenon92 then it will create your backup and you can copy it somewhere safe
Thank you

I have a problem with my i9500... after getting it fixed by a service center i got a Factory Mode is on massage and then my wifi turned off... I tried everything that i found on the web and learnt everything related to efs folder that I could have find but with no luck...
I guess its something about efs directory permissions... is there any advice there from you guys about this problem maybe a list of ownership/permissions for every file/folder in efs folder could do the trick
many thanks in advence!!!
BTW i have efs backup but its only the folder so i think its might be lacking the right permissions or ownership for the files inside...

Is your phone rooted? If yes then follow this:
1-using RootExplorer/ES FileExplorer navigate to efs/FactoryApp/ and search for "factorymode"
2 - open it with text editor and change OFF to ON and save it.
3-restart.
All the best!
Thanks for the replay...
I managed to fix the issue by deleting all efs folder and then restoring it from a backup i had... then did factory reset (all the needed wipes) and vuoala got back to user mode...
