Default Unlocked Bootloader install 4.3?

Do I have to Odin back to stock to update? I am currently on a stock rooted rom with CWM 6.0. I thought i could so i tried to install and it just came up to CWM boot and threw a few errors.

I really just need to know what to do at this point. and i couldnt find a definative answer to if i should or not.
