Firstly, what rom did you flash? Have you flashed anything else?

i tried that one too..i placed the 2 backups on my internal sd card but when i press restore efs from backup it says that no such file exists..do i have to place them in another place?or what`s the problem?can you make a short tuto please

No idea.. what would be best would be remembering how you took them....or perhaps the dev thread for the 2nd app has more info - did you read it /ask in the thread.
If you can't restore the backup, you can try and restore to stock otherwise send for repair

EFS Backup manual or automatic?

Hi every1
I see a lot of ppl on the QA complain about losing their imei number due to bad flashing and other circumstances.
I dont wanna risk screwing up my phone flashing roms so I was wondering what is the least hassle/best way to backup the efs folder?
Can u just use root explorer and copy the whole folder to extsdcard and then put the backup on the pc for future use
OR
What are the best apps for making backups and are they 100% guaranteed to make a working backup and restore with no problems?
Back up as many ways as you can, copy it to pc, use k-pack tool from the market, and copy those from your sd to pc as well, can't be too safe!
Just to update u guys pro efs will backup your efs folder to your pc no problem I recommend using this before flashing too much

Not 100% on the whole contents of the efs folder but its very important as it contains your imei number which is like a mac address its unique to your phone to identify it on a network always worth keeping a backup incase sonething happens to it

EFS is one of the partitions in the root directory which stores some of the most important data such as IMEI number, phone number etc, things which are unique to your device and will make your phone a paperweight (no network connection) if you mess with it..
Take a backup of this folder in case you face any problems..

Dear Noob..you cannot change the IMEI number yourself..you need to have a backup of your EFS folder for that..if you backed it up use the Ktools app to restore the nav_data.bin file...
Otherwise Service Center..
I hope it helped..
P.S. Post questions in the Q&A section..it is there for a reason..
I also flashed omega v14 and ended up the same as you

Looks like you are in deep trouble.
Considering you are asking this question in general section, I'll take the liberty of assuming that you did not backup your efs folder.
May be someone else can pitch in here to help you. Meanwhile you can confirm if you have the backup of efs folder or not?

Think Omega automatically backs up efs?
Flash stock GB rom gets imei back...

did you have you it will be efs zip or tar on the sd card .

Statements like that make me really apprehensive about referring people to XDA for help. Next time you have a bright idea and want to share it, just don't.

Here is a guide to repair your IMEI from the SGS2 Forum! It should be the same! I solved my IMEI problem with this Guide on my SGS1.
http://forum.xda-developers.com/showthread.php?t=1264021
[GUIDE] Recover your IMEI in 9 steps.
It is very important that you back up your efs before flashing any ROM, and before you folow this guide BACKUP the faulty efs folder because it contains the old backup of the file nv_data.bin. It beginns with a dot like .nv_data or similar (because I haven't a SGS3, but the structure of the efs folder should be similar).
Please be carefully and think twice what you are doing!!!

Restore your efs backup, if no backup then you'll need to use patched modem and kernel always.
