Insert USB with Firmware for WD TV Live Media player

Hi,
My WD TV live (Model WDBAANOOOONBK-00 has stopped working. When powered on the only message on the screen is “Insert a USB drive with firmware to recover your WDTV” I have downloaded the firmware but the device does not read the USB on several attempts. What do I need to do?

Search Google for I believe 2.21 or something download extract t it to a fat 32 USB drive place in back of devices USB slot. Show update or show new firmware click and update even if it’s a down grade. This firmware seems to work best. Good luck.

That only appears on a WDTV that has successfully booted

The “Insert a USB drive with firmware to recover your WDTV” is a pre-boot error message.
