My Note II is just rooted since a few month ago, but I dislike the custom stock so i just did FACTORY RESET cause I believe it will restore the original stock but wrong

My device can't boot up anymore and stop at SAMSUNG logo.
So, I just download the Odin 3.x, Samsung Kies and Samsung Stock for NoteII Singapore Sigtel as well.
After that I try to install according to instruction ([ Login above or register to see download links. ])

But no communication port [ID:COM] is highlighted, so I can't install the stock.
So, please guide to me how to get it back.
