Thanks your answer but;
Sure because this firmware (v2.0.5 G2KB A) was working yesterday. I trying same firmware file. I have tried few firmware but same result. I attached ss file.
I see firmware programming succesfully OK! then I pressing reset button but nothing has changed. Interesting. when connect usb cable red light is on but no display. When disconnect usb cable, the red light is not on either.
And I have tried disconnect battery. Result is same.
