UN32EH4000F Bricked! or Dead?

Hi,
I made a huge, huge mistake... Firmware update.
(1011 to 1024)
I've done everything: Info+Menu+Mute+Power, Mute+1+8+2+Power, Exit by 15 seconds, Reset EEPROM from the mainboard (VCC+SDA, GND+SDA[this config made the tv sound when it starts])...but NOTHING!!
I think the only solution is to flash the bios, but I really don't know how... Can you help me?
Thank you.

Did firmware update succeed? I mean tv showed 100 percent, rebooting now etc messages on the screen?

take flashlight and when you get TV in standby mode (red led), use Mute+1+8+2+Power and check if you get anything on the screen in the flashlight. I suspect your LED backlight is off, but in the light you could see some menus etc...

I also found in the mainboard a couple of holes that I think they're for a reset switch, but I'm not shure

The led should stop blinking? Flashlight from behind? or front?

Done it. I see through the screen, but it's like the tv try to turn on, but it shuts down. The screen makes a blink every 10 seconds

then you have firmware upgrade failure. Nothing to be done except mainboard replacement.

Even flashing mainboard? There must be a way to boot from usb, or I'm wrong?
