I have a rebadged Lite On, the Sony Liteon 1673S, need best firmware

I have a rebadged Lite On, Sony - Liteon 1673S, need best firmware for burning DVD +R and I want to change the book to DVD ROM for Xbox games?
Thanks

Go to the top of this forum. There a link to all the firmware for Lite-On including 1673s. I crossflashed mine with the 1693s f/w KS0B UFB2 and it works great.
