No luck still won't update, or from a USB stick it say's can't update in current TV mode???

I'm sorry I didn't understand, can't you even update via USB?
Manolo
No
Maybe it's the case to bring the TV back to factory settings.

I've done that twice before and still not working.
I would still try updating from USB, but first unplug all connected devices, Wi-Fi and TV from the power supply for at least 10 minutes.
