I am sharing this piece of knowledge for the folks who might face the same problem. ## Scenario I am manually upgrading a rooted Motorola Nexus 6 device, for which OTA update is not available due to system ROM modification. A populare guide can be found [here][1] or by following [Nexus Root Toolkit's][2] wizard. ## Problem Android reboots in recovery mode with a "No command" message. NRT and guides say that this is the pre-screen to recovery. I need to enter recovery and enable download from ADB. The problem is that when I do the <kbd>PWR</kbd>+<kbd>Volume+</kbd> sequence I only get the device rebooted into Android [1]: http://www.androidexplained.com/nexus-6-sideload-android-6-0-1-marshmallow/ [2]: http://www.wugfresh.com/nrt/
