Firmware needed for TOSHIBA 50UA2863DB, mainboard 17MB170?

Hello, I am trying to find USB firmware for this TV:

TOSHIBA 50UA2863DB
Mainboard: 17MB170
Panel: VES500QNDH-2D-N41

I would be very thankful if somebody here could help me!


What problem does the TV have at the moment - dead, stuck on logo, boot loop, no backlight, or just needs an update?
"Running out of memory" error, stuck, need recovery

are you sure about the panel?
