Contacted Sony - all their attempts failed.

I tried installing the latest firmware update V2605 online through TV( I have 150Mb cable), also downloaded the firmware and put onto a USB(tried the two file method also).

Every time, via TV setting software update, the download crashes at 64%(states "An error occurred during the software update, . The update server in temporarily unavailable. Please try again later Error: 2123).

The usb( usb slot 1 and 2 tried) method also crashes out into reboot at about 64% too.

Downloaded the firmware numerous time.

Any ideas ?
