Right now I am facing a situation where I am unable:

- to install new apps from Google Play Store (fails with "error 963")
- to update already installed ones ("pends" forever).

And where: already installed apps which need to write no longer work.

This seems to have started once I tried to use a USB Key to extend internal memory.

Therefore, as a consequence of trying to use a feature announced to be supported by Sony, my hole TV is now compromised and turned into an unusable state.

 We are talking about a 55KD8005 model with latest firmware.
