[q] help emergancy calls only site doesnt have information needed

Hey ive had a rooted s3 for a while now it was already done when i bought it months ago..... i decided to put 4.3 on it i thought i did it all right but obviously ive done something wrong since it now says emergancy calls only, i have tried;

taking the battery and sim out
wiping all user data and cache via the up, power and home button
I have reinstalled numerous software BTU and international and past firmwares, tried using the csc changer cause at one point it was KOR not BTU, ALL ROMS BEING STOCKS....

I have recently tried installing a Custom rom..... CYANOAGEN 4.3 (stable) which im under the impression is a custom mod anyways?????
Now i am completly puzzled ive searched numerous sites including this one but noone ever seems to have quite the same information i have on the device status or situation explanations so i thought id put this out there... erm im in the uk if that matters... and a fast response will be most helpful i will be attaching me device info screen shots OH AND BTW I HAVE A SIGNAL AND IT ASKS ME WHEN I TURN THE PHONE ON 02 MONTHLY, 02 PAY AND GO AND TESCO WHICH I AM ON GIFFGAFF (GIFFGAFF WORKS ON THE O2 NETWORK FOR THOSE OF YOU THAT DONT KNOW)
