There is no way to update the software from your PC to your HTC EVO. You will need to perform the update from Menu > Settings > System Updates > HTC software update > check now. 4.67.651.3 is the current version. You can verify what version your on by going to Menu > Settings > About phone > Software information.
I would highly recommend that you are connected to either Wifi or 4g service when checking and installing the update. This should take care of the getting stuck part that you are experiencing.
