Nexus 7 is not booting up after android marshmallow update I received OTA for my nexus 7 tablet few days back and since then my device is not booting up. Can someone please help how to get it working ?
Download the Nexus Root Toolkit from here.  It has options to restore any Nexus device back to its factory settings, including bricked or boot looping devices, under the Flash Stock + Unroot button.  You should select the option Current status of Soft-Bricked / Bootloop.  The toolkit will walk you through, step by step, restoring your Nexus to working condition.

You may lose any data stored on the device.
