My wife's kd 55xd80005 2016 was recently upgraded to oreo 8.she finds its buggy and wants to go back to 7

My kd55850c is still running 7 and is rock solid Is it possible to put the previous version on a USB stick and go back?

Unfortunately no. It is written clearly in the procedure to upgrade the tv

I thout so. If I use the recovery software, can that allow me to choose to
downgrade?

Thanks for the swift reply too.

What kind of recovery software you are talking about?

But in any case I have oreo installed and my TV is working well...which problems are so bad for your wife ?

She suffers frequent picture and sound dropouts when streaming via Plex,
and the TV will not stay connected to the Internet displaying the no
Internet connection message.

We are both connected to the same network with identical dlink switches,
and my TV running 7 has no such problems. We also have a media server with
movies etc and her TV will quit playing after a few minutes and require
starting the movie over again. Once again, my TV has no such problem. Tried
the usual reboot of both TV and router without success. The software I
mentioned is available on Sonys website and is designed to restore a
bricked TV to factory defaults. I don't believe it will downgrade the
software, but could be wrong

Regards

Regarding losing internet connection let's her try a different wifi channel on the router setting it to 1 6 or 11 and set the DNS to a public one (like 8.8.8 8).

For plex I do not have a clue since I do not use it preferring serviio as media server or better nova player on the TV via SMB sharing.

Do not think you may use that utility to install a different fw.

Tried the router settings on WiFi and cabled. Both televisions are normally
cabled anyway but she still gets the drops. I've uninstalled Plex then
restarted the TV and reinstalled it without success. Vlc which is another
media player/ sharer, also behaves the same way. It's got to be related to
the recent upgrade which she did via USB stick. We're both tech saavy
having spent years in the industry, but this one has me beaten. Now
thinking a factory reset may be our only option.

Yes, a factory reset could be a solution even if boring...

Some more details about things we have tried.

Network dropouts;
Both ethernet and wifi suffer the same problem. I have tried setting static
ip, and changing dns. It has happened whilst using other apps, some buffer
more and survive the outage. This has only started with 8.0.

Plex client isn't the problem, its console logs show a loss of stream. The
dropping out affects VLC and youtube also.

☹️😢 looks like a network bug in 8.0 at least specific to the KD-X80**
series.

Think I will raise bug ticket with Sony, and see what happens.

I know I can always Zap it if no fix arrives in a sensible time frame.

Hi Jeff,

I've got exactly the same problems you're describing. Oreo has made my Bravia almost unusable for streaming content. Very annoying as that's the only thing I use it for - I never watch broadcast TV!

Having looked into it, I'm sure your diagnosis is correct - there's a bug in the network stack somewhere which is causing network dropouts. Neither VLC, Plex nor Kodi can cope with such a crappy network connection and Youtube has become practically unusable. I'd love to downgrade to 7.

You mentioned raising a support ticket with Sony. Have you done this yet? I'd be happy to add my list of issues to yours if you've not got round to doing this yet.

All the best,

Eamonn

It was one year ago that post and three more version of the software were released. Do you have the latest?

Rif.: Downgrading TV

Hi there.

Yes, I have the latest. However, the behaviour I’m seeing is identical to that reported by the original poster. Network streaming performance has been severely damaged, having been perfect and rock-solid before the update.

I never watch broadcast tv services - I only use the tv for local streaming and YouTube, so this upgrade has made my tv effectively useless.

I’ve submitted a support ticket to Sony. I will post their response if it arrives.

That’s very interesting! I’m with sky as well - just their fibre broadband, with no tv. I’ll definitely look into the ipv6 thing - thanks very much for the tip.

All the best.
