hi guys, i am new to xbox360. i ordered the equipment to modify it but they have not arrived yet. however, i have the original game PGR3 to play with, but it reqires a software update to be installed. i assume it is to support the xbox360 steering wheel. will i still be able to flash the dvd firmware after i update the xbox360 ? im guessing it shouldnt matter since im not flashing the hdd. thanks.
