you must open up your 360 and look at the dvd drive model written on the dvd drive itself. If you actually go to the link i posted you can find most of the answers to your question. Judging by the manufacturer date i'd say you have the 0079fk/0079fl drive which require modchips for the dvd drive itself before you can flash the firmware. And posting the serial number of your xbox is never really a smart idea.
