The ACARS downloads an engine data report three times during every flight: at gear up, at cruise initiation (1:07 am), and gear down. The system was not disabled. The gear never came down so the final data report was never sent.

How do you know the ACARS was not disabled?

I do not know. I do know that 2 of the 3 required reports were sent. The AHM was not disabled. So I assume likewise that the ACARS was not disabled. Even if it was disabled, we still know the approximate 777 ground track from the AHM and the satellite ground tracks.
