Can you please provide more information about the issue you are experiencing:
-Roku device model, serial number, device ID, and software OS/version (these can all be found in Settings > System > About)
Done with the tracker ID
-does this issue occur on a specific channel? if so, what channel and what version/build is the channel (this can be found be selecting the channel on the Home screen and pressing the * button)
All channels. When you select home, all the channels are blinking with no icons. other parts of the screen are blinking too. When you select "system" everything looks normal, I can press network/update, etc. all those work fine. Go back to home and all the channels are blinking with no icon.
-tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times)
Done, see above.
-steps to reproduce the issue you are seeing
Unplug power, wait a minute, plug in power, the initialization occurs but is much slower than usual, maybe 30 secs to a minute slower. Select "Home" and all the channel icons are there. Right arrow over an icon and press enter to select it and you get the "Can't load chan..." dialog box. Press Home and now all the channels are blinking and your Roku 3 is useless.
One oddity I'm not sure of is it says my remote is a gaming remote. I don't think it said that in the past but I could be wrong. I have the standard remote that came with the Roku 3, no gaming remote and never had one. I played around with that but nothing I did could change the gaming remote state.
Seems we need to reload an earlier version to get us back to running while y'all figure this out.
