A mod chip is a third-party hacking device that is soldered onto the motherboard of a video game console. Hacking your console allows you to run custom programs or backup copies of game discs. You can modify your Xbox 360 without a mod chip using software from the Internet and your computer. Modifying your Xbox 360 will take approximately 25 minutes to complete.
Remove all accessories and power cables from the Xbox 360 console, then lift the front faceplate off the machine. Unclasp the tabs on the console's outer case and lift it off, then unscrew the Torx screws underneath. Slide open the metal interior cover and lift the Xbox 360 DVD drive out of the case. Unplug the SATA cable from the console to the DVD drive, then connect your SATA cable from the DVD drive to your computer.
Turn on your computer and download an Xbox 360 modification program. Install the program, then run it. Select your Xbox 360 DVD drive from the main menu, then click "Flash Firmware" to begin the modification process. Click "OK" to confirm your selection and the program will modify or "flash" the .BIN firmware file on your Xbox 360 DVD drive. Flashing your console's DVD drive allows you to run backup copies of discs on your Xbox 360.
Close the program and shut down the computer once flashing is complete. Unplug the SATA cable from the computer to the DVD drive, then reconnect the SATA cable from the Xbox 360 to the DVD drive. Lower the DVD drive into the Xbox 360 case and close the metal interior cover. Replace the Torx screws and outer plastic case. Put the front faceplate back on the Xbox 360 and reconnect the accessories and/or unplugged power cables.
Opening the Xbox 360 will void your warranty from Microsoft.
