Elite 100 V2 Won't Turn Off - Broken Update

I recently updated my Elite 100 V2, but now I cannot turn OFF the unit. When I press and hold the Power button the word GRID simply blinks, but the unit never shuts off!

This needs to be fixed, as we have several locations with units like this, but I am telling none of them to update until this is resolved.
