Default Camera error

Hello guys. I tryed the Official MIUI rom for the internation Samsung S3 but I didn't finde it to fit me that well found minor things with it. So I decided to download other unofficial MIUI roms for the S3. I found some that I like over the official one but then a major error appeared, the camera isn't working at all. I downloaded apps from the store but nothing worked tryed fixes for S3 cameras nothing. The same thing is with every unoffical MIUI roms only offical one works.
Is there a way to fix this ?

I flashed the latest versions of all the roms with Phillz Recovery. For some reason CWM Recovery didn't let me to flash and my Baseband version is I9300XXEMG4,
