Open the "Step 1_Create" folder and select the "XMB" icon you would like to customize.
Open the image you have chosen in an image editing program such as Paint or Photoshop. Make the edits you want and add photos or other images.

Change as many icons as you would like using the same steps.

Open the background in your image editing program and make the changes you want.
Save the background image as a "JPG" file in the "Step 1_Create" folder.
Open your "Step 1_Create" folder and size it to take up half your screen. Open the "Step 2_Assemble" file and place it on the other half of your screen.

Press "Enter" when a new window pops up and "Done" appears.
Place the USB drive into your computer and go to your "Step 1_Create" folder. Copy the "PS3Theme_TEMPLATE.p3t" file to the USB drive, into a "THEME" folder you create for this purpose.
Remove the USB drive and place it into the PS3 USB port. Turn the PS3 on and go to "Settings," "Theme Settings" and "Theme."
