Default Trying to use Casual with rooted 4.1.2 on SCH-1605(note 2)

Im a noob and have been trying to use casual to unlock my bootloader. I have a rooted version of 4.1.2 flashed through odin on my SH-1605. Ive tried it twice now and it hasn't worked. This is what i am getting from casual. I had to shorten it quite a bit but i think i got the main error.

This is a tool which will root, unlock, and install a custom recovery on a Verizon Galaxy Note 2.
