I'm having this same problem too. Last night I got notification to install, I accepted, and was told it would reboot to start the installation process. I let it restart and all it showed was the White google logo on a blackscreen. I figured it was doing it's "thing", so I left it there for over two hours and all it did was keep showing the white google logo. The only way to get this phone working again was to remove the battery for a force restart.
Does anyone know the solution? Can anyone at least tell me how to stop it from notifying me to update at least? So annoying.
