Original version:
Nexus 9 boot failure - Security patch July 2016 SOLVED

The Android Marshmallow security update for July 2016 caused boot failure of my Nexus 9 tablet. The error message is shown in the picture on the right: "Your device is corrupt. It can't be trusted and may not work properly"

After a while it reboots and ends up with the picture shown below:

No Command
No Command!

Device Corrupt!
Device Corrupt!

SOLUTION: Update 2016-07-15
Tried to apply the factory reset, but it ended up with the same: "No Command"! Instead I flushed the factory image successfully, following Techno Bill's Guide.
