Download file on your phone. Once complete open Root Explorer and navigate to /sdcard/downloads and long press on the zip you just downloaded. Choose to extract all to /sdcard/extracted
If you don't already have the app download Font Changer from the market (free). Once downloaded navigate in Root Explorer to /sdcard/extracted and copy both Roboto font files. Paste them in /sdcard/.fontchanger. Now open up font changer and apply Roboto font!
