Not sure how this mod was done. I purchase an XBOX 360 Arcade edition way back in 2007-8 (HDMI). I went to a mod place to mod it. Back then, it was impossible to mod it because of the new DVD drive (I think it was a Lite-on?) so I paid them extra so they could install a Samsung drive in it and they did their thing. They had a huge lot of Samsung drives in a box and put it in. Modding updates/changes the firmware on the DVD drive right? So does that mean the Samsung they installed is modded while the Lite-on drive is UN-modded? I don't understand where they got that huge box of Samsung drives and don't understand how the "key" is attached to identify the Xbox 360 online.
