[Q] How to restore to 4.0.3 from JB 4.1.2 STOCK leak?

[Eslf]

Hey everyone, I would like to know if after I've installed the JB 4.1.2 Stock Leak on phone I could just restore it by flashing a ROM using Odin (the ROM that you can download from Sammobile) or I need to do something else?

Note: I got Philz CWM 6 Kernel and root on XXSJ.

Sorry if it is kind a noob's question, but thank you for your help.

Yes.

But do I need to change the kernel or can I keep Philz's?
