Motorollin is right.
Use the flash ROM tool to select only the items you want and then reflash it. When you run it all the available modules will be listed in the left hand screen and you can select what you want so they appear on the right. Then reflash and you're done. Remember selecting an item doesn't add it to whatever is in the flash ROM, the contents of the ROM are wiped and replaced with whatever is in the right hand window.
