Modifying---or "chipping"---an Xbox 360 enables it to perform functions not sanctioned by Microsoft. You must violate the Microsoft warranty by opening the Xbox 360 to install a mod chip bought from a mod-chip supply store. The mod chip is soldered to the motherboard of the game console, requiring adult supervision if the person soldering the mod chip is underage. A Xbox 360 that has been "chipped" will be able to run programs created by other game enthusiasts.
Put the bath towel on a table. Remove all of the cables from the Xbox 360. Stand the Xbox 360 on the bath towel with the hard drive compartment lid facing up.
Release the latch on the side of the hard drive compartment lid with your fingers. Pull the hard drive compartment lid off the Xbox 360 with your hands.
Grab the upper left corner of the faceplate with your left hand. Pull up on the lower right corner of the faceplate with your right hand. Pull the faceplate off with your hands.
Put the Xbox 360 down horizontally on the bath towel with the power button facing you.
Insert the tip of the flat-edged screwdriver into the upper-right hole of the ventilation grill on the right side of the Xbox 360. Wiggle the tip of the flat-edged screwdriver to release the plastic latch that is inside.
Move the tip of the flat-edged screwdriver across the top edge of the ventilation grill and into the holes to release the three other plastic latches that are inside.
Repeat the procedure to release the latches from inside of the ventilation grill on the left side of the Xbox 360.
Turn the Xbox 360 face down on the bath towel. Lift the bottom shelf to reveal the 14 screws.
Remove the screws with the Torx 8 screwdriver. Turn the Xbox 360 back face up on the bath towel.
Lift the outer casing off the Xbox with your hands. Remove the screws from the back panel with the Torx screwdriver.
Pull the two plastic inserts from the left and right sides of the Xbox 360. Pull the back panel off the Xbox 360.
Remove the screws from both sides of the DVD drive with the Phillips jeweller's screwdriver. Lift the DVD drive up with your fingers.
Pull the two cables out of the back of the DVD drive with your fingers.
Remove the screws surrounding the metal plate with the Phillips jeweller's screwdriver. Pull the metal plate off the Xbox 360.
Release the latches from both sides of the metal grill near the top-right of the Xbox 360 with the tip of the flat-edged screwdriver. Pull the metal grill off the Xbox 360 to reveal the two computer chips beneath it.
Blow off the two computer chips with compressed air.
Line up the mod chip frame that comes with the mod chip so the notch in the upper-left matches the position of the notch of the smaller of the two computer chips which is the CPU chip. Press the mod chip frame down onto the computer chip with your fingers.
Cut a 4-inch length of electric wire using wire cutters. Strip a half-inch of insulation off each end of the electric wire.
Solder one end of the electric wire to the ground-labelled contact on the bottom of the mod chip. Let the solder cool for a minute. Solder the other end of the electric wire to the ground-labelled contact that is to the right of the CPU chip. Let the solder cool for a minute.
Line up the mod chip so that the notch on it matches that of the mod chip frame. Press the mod chip down onto the mod chip frame with your fingers.
Apply solder to each of the two sets of pins on the mod chip where they meet the mod chip frame. Let the solder cool for five minutes.
Blow off the computer chips with compressed air.
Put the metal grill back onto the Xbox 360. Re-engage the latches on both sides of the metal grill with the tip of the flat-edged screwdriver.
Put the metal plate back onto the Xbox 360. Reattach the screws. Plug the two connectors back into the DVD drive. Place the DVD drive back onto the Xbox 360. Reattach the screws.
Reverse the disassembly process to reassemble the Xbox 360. Reattach the hard drive compartment lid to the Xbox 360. Plug the cables back into the Xbox 360 that now has a mod chip in it.
Wear an anti-static strap when the Xbox 360 has been opened, as to minimise the risk of static electricity ruining the electronic components.
Incorrectly soldering the mod chip will disable the Xbox 360 entirely. A modified Xbox 360 will be denied for any warranty service by Microsoft or an authorised service centre.
