Sorry I see it, 0225. This is crazy, what options are you selecting after "Get Slim Key"? ...Don't unlock.
I KNOW liteon 9504 but on jf it say 0255 so im lost i follow this vid http://www.youtube.com/watch?v=4edHp_ltFpQ
Think im suppose use the ide for something ima keep looking f your PC see's the drive then give it a shot and try to extract the key, you got nothing to loose i don't know if its gonna extract the key but it might.
