Hello. Firstly, I'm sorry to say that I don't have much experience as mine came directly from ICS. I can suggest a long roundabout way which is to update your android vers. from GB To JB through Odin procedure first, then just flash philz safe kernel. and then flash any roms u want. Or if you just want stock JB, then u can download stock JB firmware n flash it through odin.
Edit : Go Here
And watch the video and read. The link for the kernel provided includes CWM. After Installing CWM, you can directly flash philz safe kernel, reboot to recovery, do a clean wipe and formats (Follow OP of the rom you want to install)
