Once you upgrade the SM App from the market (which is version 7 I believe), open up the app. The app will ask if you want to go back to 2.0.1 (no root), 2.0.2 or 2.0.3. If you choose 2.0.3 and you dont have it already on your SM Card, then it will download that. After it's done downloading it, the program will ask you if you want to flash the rom or not. Flash it...the phone will reboot into the install screen and then I'm sure you know what to do from there. Make sense?
