New Firmware April 12

Today I can see a new firmware is available through TV settings.

But, I do not see this available for download and install from usb.

I'm confused, Sony seem to be saying that the issue is solved but I am still getting ui-800-3 when opening Netflix.

BT Home Hub 5

Have you tried

- Logging into MYBT and disabling (if needed) BTProtect and BTParental controls

- RESETTING as opposed to restarting the hub. The reset option is located at the back and involves pressing a pin against it. 

I had the same issue with a BTHUB5 and resetting it fixed the problem for me
