A Torx screwdriver is a Phillips-style screwdriver that is used on specific small screws in various electronics. A size 10 Torx screwdriver is usually used when disassembling an Xbox game console and removing its screws. However, if you don't have access to a Torx 10 you can actually use a regular screwdriver to open the Xbox. A regular screwdriver won't affect the disassembly process; you just need to make sure it's small enough to fit in the grooves in the screws.
Turn off the Xbox game console and unplug the controllers from the ports in the front of the device.
Turn the Xbox over and use the tip of your flathead screwdriver to pop the four rubber screw covers from each corner of the bottom of the device. Use the tip of the flathead screwdriver to pry up the two information stickers in the centre of console.
Use the Phillips-head screwdriver to remove each of the four corner screws and set them aside. Remove the two screws revealed under each of the stickers and set them aside.
Turn your Xbox right side up and gently lift the top frame off of the device from the sides. Set the top frame aside. The Xbox is now open.
Opening your Xbox will void any warranty you may have on the unit.
