I ended up having had 'hard boot' the new firmware since I could not get it powered up to even get to the update menu.
Basically, even with the red LED flashing, I plugged in the USB flash drive containing the firmware to the USB port and held the power button on the TV until the amber LED that signifies USB activity starting blinking. Let it install (even if the screen is blank, it'll bring up the set up menu in 7-10 minutes when the firmware install is complete).
The most recent firmware is on the Sony site at the following address:
