So I got the clock on our Model S, this will be our second software update since ownership, but first one just happened while we slept. I hit update now and walked away. Came back 20 min later to check on the status in the garage, lights flashed a few times while I was there, I heard what sounded like AC system checking itself. Main screen was black and screen behind steering wheel just showed current state of charge in the new graphic seen in 8.0 with a warning saying "Software update required, contact Tesla". Touched main screen, it came on with "update complete, checking systems". I thought sweet, it's finishing and walked away. Fast forward, 15 min later and I walk up to car, handles present, no AC, no radio, both screens black and non responsive. Did update hang up? Or is it still system testing and screens stay black for a period of that time. Still haven't received update complete notification from the Tesla app like I did on first update. Just don't want the car dead in the water tomorrow morning.
