This blog entry title would have sounded really strange a couple years ago. But Smart TV's are really computers already. And their features can be updated by loading the proper firmware.
I've been trying to figure out how to make our qwerty remote work with the U55D6600WP. It actually uses Bluetooth technology to "pair" with the TV to send all those keystrokes. But it will not work with the firmware that comes shipped with the TV.
I could not figure out how to make the TV perform a firmware upgrade via its Wi-Fi connection since the button is disabled. So I opted to download the firmware on a regular computer; transferred it to USB; and performed the firmware upgrade via USB.
The upgrade went smoothly and the qwerty remote is now working!
