well ... this is very strange that I cannot even shutdown the box by any means ... tried everything.

I think, VTi v13 has a whole lotta bugs/issues... I am going back to 11, folks !

It should be obvious that the basic functions like Deepstandby or Shutdown should be as default. If anyone wants change them, they can later.
You are asking users to search/forum and configure the box forehand, that's not the way it should be, that's why I went back to 11,so I cannot TEST anymore.

there are many plugins either don't work or doesn't work properly with 13, like MultiQuickButton.

Waht you mean by only by you? Please read the other threads here.
The developer/others of MQB already admitted that default Key Button's names will not change.

As for your other suggestion, I already spent all yesterday by flashing v13 clean without any back config, etc.
And at midnight before going to bed that the box do not get shutdown yb Deepstandby (it restarts) !

So, are you saying "Wrong" should mean "Right" here, and "Right" should mean "Wrong"?

Thanks anyway
