yes you are right, I recover it for a sentimental value because it is a gift from a person who is no longer there. i tried to flash with the firmware “A02E0Y0-F000-GN1-R6”. did it correctly the button turned blue. I turned the main power off and on again as it says on the service manual. but when it starts it is still stuck on the hourglass, could it be the nvram to be reset? I also have this firmware A02E0Y0-F000-GEQ-J8(00) if I understand correctly it is used to reset the nvram is it right?
