So it was originally on 4.3 and i was told to downgrade to 4.1.1 to unlock it so i did..
I ran the GalaxSim Unlock app to unlock it but its saying invalid IMEI now :/
I dont have a backup of anything what can I do to unlock it..
Thanks.
You should to install 4.4 version to unlock it. It is the latest version.
How would i do that?

4.4 won't help anyone, you can't downgrade to 4.1 without an efs backup to restore. Pay for a code.

Well I know the imei number its supposed to be (on the box)
anyway I can restore that?
Usually when the imei is invalid it means you have damaged the /efs folder, the only way to repair this is by restoring a backup.
However first try flashing a stock rom again, just to be sure, if it's still invalid then the problem is definitly the /efs folder. Because the /efs is specific to each individual phone there isn't much we can do. Moral of the story is to make sure you make a /efs backup. The app you used should have a tool to backup the /efs folder, and this should have been done before trying to write to it.
I did copy the efs folder to my sd card before doing anytjing with it...
But copying it back just made it have yellow text on the homescreen...
I tried reflashing back to 4.3 but no solution...
EDIT:
After copying it again it made the text go away but my IMEI is still 0049...
Any help?

FIXED IT, Got the IMEI back
Is there any guide now on how to unlock the phone? Currently on android 4.1.1

No, the phone is rooted and has a custom recovery.
I want to SIM-Unlock it so I can use any networks sim on it.
The easiest and safest way is to contact the carrier whom the phone is locked to and ask for an unlock code, they should give you it, but might charge (I'm not sure how much.)
Try to do the nv_data.bin method.
You won't find the md5 value in the log (Samsung patched that a while ago), instead, run this on a Linux machine (or in the Android terminal):
(cat nv_data.bin; echo -n Samsung_Android_RIL) | md5sum

Samsung updated the efs in one of the 4.3 roms and above. Your 4.1 rom doesn't recognise it as the 4.1 rom cannot read a V2 efs and since you started out with a v2 efs you cannot do anything with Rom versions below 4.3.
Restore your original rom or install a custom 4.4 rom regain your imei and either pay for a code or contact your carrier. This app is useless in your case..

I actually went into my local town, went into one of those "phone unlocking/repair" shops and paid £15 to get it done. Was done in 30minutes and works beautifully.

You go by your kernel version, not the build version. And once you've rooted try the helroz unlock app on the play store called galaxy_s unlock

And how else he would access EFS folder? Use method 1 from 1st guide in my signature. Simple and quick method. Then there are basically 2 apps you can use. One is able to calculate unlock code (Galaxy S2 SIM Unlock from Chainfire), but your HW revision must be older one. If you have newer version then use helroz app (Galaxy_S Unlock) which will patch nv_data.bin file to unlock it. Oh and don't forget to make backup of the EFS folder before you do anything.

You're supposed to backup EFS before you bork it. Once it's borked, you're boned. What you're trying to do now is futile.
You have two options; service center or contact Odia by PM (and wait patiently for a reply. If you harass him he'll probably/quite rightly ignore you) & he might be able to recover it for you for a small donation (cheaper than paying Samsung/authorised repairer to fix it).

Using sometime else's nv_data.bin file won't help you. That file contains unique information for your specific phone, including your IMEI number.

I've try to cut it short.I would like to debrand (sim unlock) my SGS3, I used a tool named GalaxSim Unlocker, but it sad

What is it? How can I fix this? or there is other method to network unlock my phone ?
HELP ME
THANK YOU GUYS BEFORE
Best way at present is to purchase an unlocking code from your network. The previously posted free methods don't work anymore due to changes by Samsung to the efs folder.

Is it possible to downgrade the rom and the modem for the one click method ?
Cost for a code varies, contact your network and a few repair ships to compare.
Yes, you could downgrade to older baseband -but only if you have a backup of your pre-MG4 efs folder and know what you're doing. Chances of bricking the phone are fair and you'll be stuck on that baseband, any upgrade will again lock the network.
That's why I said a code is currently the best option.
OK

Hi,
I'm currently running omnirom 4.4.2 nightlies on my I9300.
I want to unlock SIM network without a code, because any code providing by MNO won't work.
Now, from what I understood, the only way to unlock SIM network by myself is to flashback from 4.4.2 to 4.1.1. Now as you may know, 4.1.1 modem expects an EFS v1, and starting from build xxemg4, modems expect EFS v2...
So I can always flash an xxemg4 modem once I flashed back to 4.1.1, but it won't help because this SIM unlocking method only works on an EFS v1...
So, for now my question is: How can I downgrade EFS v2 to EFS v1 if it's even possible?
I apologize if this question has already been asked an hundred times, I'm taking any other alternative solution to unlock SIM network if you have one!
Thanks in advance!
Only if you have a backup of your efs when it was v1, if already on v2 and no backup then there is no way to downgrade.

Unfortunatelly, I don't have any backup of my EFS v1... So I guess there is no other method to unlock the device than getting the right code?
I've heard it could be done through a wire using some software from a PC?
EFS V2 can read efs v1 .but if you want to unlock your phone it's another process

I'm not sure to understand... You mean that if I set the right permissions on EFS files before flashing back from 4.4.2 to let's say stock 4.1.1 (which includes a modem pre xxemg4), it somehow downgrades EFS v2 to v1?
If so, that would be amazing !
