and began to leave 4.3 official few days ago. if you downgrade to 4.1.2 can install a modem having supeior mg4 or so you would not have problems imei.

If u did not back up ur efs before u flash 4.3, it is useless. Not entirely useless but useless at this situation.

Download XXEMG4 firmware from sammobile and flash it using ODIN (Same way you did for 4.3)
Did you do a nandroid bk up? Restore that? When you flashed 4.3 it's changes efs. So to fix network simply flash mg4 or newer modem. I use mj3 modem that comes with 4.3 mg9 firmware.
Please refer and use help threads which have already been made on these topics.

Flashing roms in CWM is same in all phones...
If you looking for an AOSP roms, you can try SlimBeans... I use it and its really smooth and fast and low battry drain
If you Looking for Samsung base Roms, Try Wanam Lite or Android Revolution HD...
there is lots of note 3 ported roms but i found most of them laggy and unstable...

I have flashed lots of official roms, but i didn't see any important differences between different countries roms... Just some language features...
I'm persian but i flashed MK6 rom that is for Europe, I've got no problem... I can even type Persian...
For 4.3 rom, you've got just few choices and best of them is MK6... The other 4.3 updates have a lots of bugs but MK6 is almost bug free rom...

Downgrade from 4.3 to 4.0.4

It is possible to downgrade from 4.3 to 4.0.4 ? if is,how to do it ? via odin ?
No, unless you have an efs backup from before you upgraded to 4.3.
Also, 4.0 will kill your phone.
why,4.0.4 is stock firmware for s3 when s3 build.
Search and read about SDS, a bug they fixed at 4.1 firmware EMG4. Anything earlier than this will destroyed the nand memory.
slow to upgrade to 4.4.4
why do you think better 4.0.4
ok,can i downgrade to 4.1.2 ? i am now on 4.3 NeatRom.I think device performe faster,little more ram memory is free than 4.3

Download 4.1.2 version minimal XXEMG4, not older (letters before G are older, far from G newer) and flash via Odin.
You can find firmware on sammobile (not allowed to post link due to rules).
Also, if you don't know how to flash via Odin, look -> here
i need 4.1.2 for Serbia (Telenor).When i type i9300 on sammobile,just gave me 4.3 firmware

You should've done some reading first:banghead:
I am afraid to ask if you have Efs backup?
Flash 4.3 again and pray . If it recovers(imei) then downgrade to 4.1.2 and when you choose firmware be sure that it's not below mg4 modem.
Backup Efs after flashing 4.3 if you get back your Imei.
