If you've never done this before, you have a HIGH likliness of messing everything up!
Be careful about it, but what you would need is solder, and a soldering iron. Especially with little bitty technology, you'd want to be careful, as it's a horribly delicate operation.
Unless it's the simple matter of removing, and replacing a chip, which, based on the technicality of the link you provided, seems to be evident.
