Say what? You don't have the serial port connections up and running yet?
Heck, I waited 20 minutes.
In general:
Try to get into the recovery menu -
Export FAT partition -
Connect USB cable to computer -
Put Amazon PW2 update_*.bin in root of device -
Eject (or safely disconnect) Kindle -
Disconnect USB cable -
Reboot
That *should* install the non-demo firmware for you. (your done - put it together)
