Because you have 4.3!!!!
You need to install CWM Recovery then install this zip: http://filecloud.io/82jonx71
(i9300 Only)
Then do what I said in previous post
This will work on 4.1.1 only, both EFS v1 and v2 work
Solved
So guys, I did it. Thanks to all!!!
1. For fist run GalaxSim Unlock looks like this
2. Replace EFS folder ( from 4.1.2 befor XXEMG4. I have older version backup EFS). Check Permission. DONT REBOOT DEVICE!!!
And run GSU and looks like this
3. Press Unlock! Reboot with another sim and run GSU
Proffit! Network it work.

This won't pose problems if I come from a different carrier but still an i9300?
Three in Austria never had an i9300 on version 4.1.1
Not working
Hi,
My I9300 refuses to downgrade using CWM with the 4.1.1 rom.
Is it possible to use Mobile Odin ?
Thanks

Try using TWRP, or this custom 4.1.1 ZIP - https://docs.google.com/file/d/0B8hMFk8A6VXsR0lYQWdxdVZ0ZGc/edit?pli=1
any success story?
Have tried FW from link above v4.1.2
Downgraded.
missing menu after "network lock"
entering 3, after that "back" and entering 4 does not work.
s4 gt-i9300. any sugestions?

Then what about all these ways to imie fix if i don't have my efs can i do that
If you want your IMEI restored then take it to a repair shop on pay them to do it, you can't do it yourself.
So, if unlocking efsv2 is available - why does your program say my phone is in an offline state?
because it's not detected by our tool.. because you did not installed the drivers, because etc etc
ADB did not see your Phone.. EFSv2 is fully supported for unlock

I think I have some kind of same issue , but the difference is that my phone is never locked . I upgrade it to 4.3 and the phone started to give me an error after every call attempt " Not registered on network" I think the problem is in firmware. It is not my country or mobile operator based .
So is there any firmware without country or carrier lock ? my Imei doesn't damaged it is unchanged . and thanks in advance

No this is nothing to do with unlock because you upgraded to 4.3 your efs as changed from efsv1 to efs v2 you probably need the patched modem and kernel files look here >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << dont forget to reboot to recovery and factory reset if you get a bootloop after flashing.

I'll find way how to change them without a doubt , but I need some help please advice me how to figure out what kernel to use from given your's above .Is there any differences between them ?

Ok no problem here is a quick guide but please read and understand what you are doing first look here for some guides to help you >> http://xdaforums.com/galaxy-s3/general/samsung-galaxy-s3-sticky-roll-thread-t2344125 <<
(1) Download Odin and Samsung drivers (please read guides on how to use)
(2) Root your phone ( use CF-Root >> http://xdaforums.com/galaxy-s3/orig-development/03-07-2012-cf-root-6-4-supersu-cwm5-5-t1695238 <<
(3) Place the patched files on ext sd card and use cwm to flash the patched modem and kernel ( cwm is included in CF-Root) if not you can download and install it with Odin
(4) Reboot you should then have a signal.
If you get a bootloop in any of the stages above reboot to recovery and factory reset/wipe cache
Please note the above is a quick guide please read all the guides and be sure you understand them before doing anything.:good:
As for which files to flash you can use any patched kernel and modem but I would probably use the Patched_XXUGMK6_modem.zip and the Patched_XXUGMK6_kernel.zip
Good luck and be careful.2I following key, but nothing not to do. Andorid 4.3
