Not all falcon consoles can be modified yung mga luma pwede pero kung ngayon ka lang bibili hindi na pwede. They did something kasi sa DVD-ROM drive kaya unflashable na siya. Dati kasi they use a solid state chip to store the BIOS of the DVD-ROM. What the pirates do is change the BIOS by erasing the original BIOS and replace whith a hacked BIOS thus the DVD-ROM will accept illegal discs. Now I don't know how M$ did it, the BIOS is no longer stored in a solid state chip so hindi nila mapalitan yung original BIOS.
