[Q] EMIE change after omega rom installed

Hi everyone,
I hope someone can assist me.
I rooted my i9300 device using Samsung Galaxy S3 ToolKit.
After installing Omega ROM 46.1
What i discovered after installing omega rom is that my IMEI number had changed to 004999010640000 and am no longer registered on my network.
I then went to rom manager as i had a backup of my sock rom i restored it but still no network says not registered to network.
i went to a couple of forums n dowloaded offical stock rom from this link (http://forum.xda-developers.com/showthread.php?t=2005286) still no network no back up nothing and the emie is still changed 004999010640000.
current version on mmy ph is
GT I9300
model 4.1.2
basebande version : I9300xxemb6
kernel version : 3.0.31 -1071725
build number : jzo54k.i9300xxemc3
after installing stock rom from this link (http://forum.xda-developers.com/showthread.php?t=2005286)
So basically:
I get the wrong IMEI number when running stock android from Samsung.
and nothing seems to work as not network
Can someone assist me with this? as i am new to changing roms .
You're going to have to search, as discussion of methods to change a device's IMEI is illegal in many places and cannot be discussed on XDA.
Sorry that it's not much help, but the answers are out there if you use Google properly.

Go to Faqs and Guides and read and post in the EFS/ IMEI thread we do not need yet another thread.
As it looks like you failed to backup your EFS as per the instructions its best to take it to a service centre for repair .
Please read the stickies then if you have any questions post in the sticky thread which is actively maintained. Also its IMEI not EMIE

[Q] No network after Odin flash

Hello all,
I live in The Netherlands and I had bought the Samsung Galaxy SIII from a telephone provider in the Netherlands.
I had an official ROM for the Samsung Galaxy SIII and everything worked ok.
It was working on Android 4.1.2. and I wanted to flash it to Android 4.3. with Odin. It was the first time I ever flashed something in my life so I was very happy that it seems to turn out well.
But I discovered that I have a big problem on my hands know because my IMEI is completly gone, my phone number has become unknown and my network is gone too!
I still can use WI-FI on my phone but that's it!
Does anyone has any idea how this can be solved?
I am aware that there are simulair posts here with this subject but it didn't help me so for that reason I desided to post a new one for this issue.
Thanks in advance!
Follow these guides if they can't help sounds like a service job..
Please tell me you backed up your efs?

Well what modem are you using. Please ensure you are using XXEMG4 or above modem.
Read the efs 'know this stuff' thread, it may not fix your problem if you didn't back up your efs folder first -but it contains the reason for your problem and the only answers.

Hi Friends
I am having a serious problem on my s3. It is showing a Sign of Network (Network Bars) at the top side of the screen but still showing Emergency Call Only. I have tried flashing Different Custom Roms and Modem but it is still having the same problem. Pls help me with suggestions to fix the problem. My Country's Firmware Is 19300XXEMF6 19300JVEMF1 ECT but terafile has deleted the file as hosted by Sammobile. . I will be so Glad if my phone can come back to life.
Thanks so muchThanks
My suggestion is don't post duplicate threads, search and read before you ask a question asked many hundreds of times already.
There is a specific thread in the sticky posts, over in general forum - efs 'know this stuff'.
