Device receives a required update Progress 0% Status Code 800 message repeats every 15 minutes

Gotcha, thank you for checking out those troubleshooting steps on your end. I can only imagine your frustration in dealing with that every 15-minutes. Especially when you just got a new TV and to kick back and enjoy it. It might be that the splitter needs to be replaced, as they do go bad sometimes. The best way to restart your cable box would be to do a hard reset. To accomplish this you would unplug the cable box from the power source for 15-seconds, then restore power. Can you please let me know if this step resolves the issue? 

Hey there, @espear!

I hope you are having a good week! Have you tried using the My Account app and walking through the troubleshooting guide? It is super helpful when it comes to situations just like this. Here is a link through a webpage as a guide, just in case you have not used the app before.

You can also check to see if there is a splitter that your TV box is hooked up to. Our customers usually have splitters when there is one outlet and they have TV and Internet service. Those can be a cause of issues like this too!

If that does not work, let us know here through your thread and we can do a bit more in-depth troubleshooting for you. 🙂 

Thanks for the quick response.  I have tried the web based trouble shooting to reset the cable box but it tell me it cannot do it but try the unplug for 30 second method.  Which has also not worked.  As to the splitter this has been a working cable connection for years.  I am upgrading an old tube TV connection to a HD flat screen.  As I say everything works fine for about 15 minutes then it trys to reset itself but fails to strat the reset and then the picture just contines.  Anyway to FORCE a reset?

In case you can't display the image the Message reads:

Please wait while your device receives a required update.

The update should complete in less than 20 minutes.  During the update, the adapter may automatically reset.

Sorry for the inconvenience.

"a status bar"

Status Code 800

That is the message.

My guess is the device can't update itself and is defective.

Thank you for sharing that the information about the error message you are receiving. I'll be happy to run through some trouble shooting on my end and see if we need to swap out the box.
