Shield Portable OTA 1.1 Update breaks Unity Deferred Renderer

The latest 1.1 update to the shield tablet broke deferred rendering on the tablet - colors washed out. No shadows.

In addition, a forward rendering build with shadows that works on Shield portable has no shadows on the tablet after 1.1.

Are there any recommendations/documentation/assistance with getting Unity to run on the Shield tablet?

In particular, what settings to take advantage of k1?

Nevermind - I figured it out - had some new assets with a non-mobile shader
