It download the firmware over wifi (unfortunately, I didn't take note of what version the old and new was, but the driver version of the new was blank.) and said there shouldn't be a disc inserted during update and ejected the tray. I didn't take the disc out though, assuming leaving it ejected was enough. It then did the update progress bar and at some point it finished, pulled the drive tray in and showed the LG boot logo, then black screen, then the TV indicates no signal.
Now nothing happens. If I power off (red LED) then power on (green LED, drive noise), the LG boot logo will show for about half a second, then black screen, then no signal. The LED remains green and blinks if I send remote commands, but nothing ever happens.
Did the firmware update brick the player? Was it because I left the disc in the tray?
Any way to recover? I haven't found a firmware download yet to try manually updating via USB or disc.
Update for future reference in case somebody else runs into this problem:
I was about to send this player back to LG so they could do a manual reflash when I saw somebody on blu-ray_com mention that they ran into this and the problem was related to Deep Color. So after I saw that, I turned off deep color on my TV (LG OLED65B7A) and could now boot the player and see the menus and start up the disc. I had assumed there was some sort of firmware update failure and that the player was not able to completely boot itself after the update, but it was actually booting up but some sort of incompatibility between what signal it was putting out and the Deep Color setting on the TV prevented anything from being displayed.
But after that I still could not turn on Deep Color without everything going black until I turned it off. When playing an HDR disc (testing with Avengers Infinity War), the TV would prompt to turn on Deep Color and not give any option not to, but when I clicked OK (only option), then everything went black again. I went around and around with this fruitlessly for a while. But while looking in the player menus for anything relevant and not finding anything, I finally tried Initialize to factory defaults. That worked so that I could turn on the TV's deep color again and view the player menus.
So, it looks like LG's firmware update has some kind of bug with Deep Color settings after updating and the solution is:
1. Turn off Deep Color on your TV so you can see the player's display/menus again.
2. Initialize to Factory Defaults in the LG players Settings -> Others -> Initialize -> Factory Set. Go back through the Setup process for the player.
3. Turn TV's Deep Color back on.
