thanks for answer peste, i tried with your dump but it has de same problem, shows display but keyboard and backlight keyboard does not work, i tried again with my original dump and it does not work either , im thinking that the kbc it8252e248a it is corrupted, can you tell me where to find the dump of the kbc and how to program it with a rt809f programmer, or do i need to replace that it8252e248a?
