Chromecast update stuck at 0%

My Chromecast has been perfect for more than a year… until this week. It’s basically stuck on the update screen at 0%.
Steps taken after checking several forums, blogs and vlogs.
– Reboot/reset to factory settings
– Rename chromecast
– Connected to power supply other than the TV usb port
– Changed DNS settings on my router (primary 8.8.8.8 secondary 8.8.4.4)
– Called Google who agreed to send me a new Chromecast but I live outside of the US and they can only deliver to US based addresses (I bought the Chromecast while I was in the US).

Any ideas?
Thanks
