50 W829B reboots now and again and Netflix problems

[Arcticwolfy]

Hi since the last update I've noticed now and again the TV will reboot itself for no reason. It's not happening every day and it can either happen when I first turn on the TV or when it's been on a while.
Then Netflix also has a problem telling me there is some error connecting to it. Yet if I restart the app it works just a small bug.

Mine also reboots spontaneously, from the latest updates (now running PKG2.303EUA on a 50W805B)

I also got the 8 red blinks a few times in the morning, suggesting the tv hung itself during the night.

I am using the satellite tuner, with many channels, wired Ethernet and a Raspberry Pi. When I just had the tv, I had similar issues, but they were solved many updates ago - until 2 weeks ago.

Would it be possible to downgrade to the previous firmware, that I can download from this site?
