Konka led40x9500uf android tv firmware update failed

[asdas014]

I put the wrong update, it was a model Led42x9500uf..

Now, turn on tv and it show black screen with backlight, but not show anything else.

Press the buttons on the remote control when the black screen, I hear the TV menu, the movement of the sound.




What i can do that it works again?

I saved the original model for the firmware update to a memory stick.

How can I make a bootable memory stick, and it will start to install the firmware update automatically when you turn on the device? or something good idea?

TV turns on but only a black screen and the backlight.
