[Q] cant flash 4.4.2 rom topic

I attempted to flash a 4.4.2 rom yesterday but it couldnt and it gave me a status 7 error. I looked it up and people said that you have to update clockworkmod. Well i tried to through terminal but it couldn't. It said something like could not find directory. So if anyone has any idea what I can do pleast tell me.

Using Galaxy s3 sgh-i747 on PA 3.99.1 ROM
