[Q] Nexus 7 suddenly show "No Command" after reboot, won't turn on
Hi, I installed PA Kit Kat on my Nexus 7 a while. Yesterday after restarting the device, when I tried turning it on I saw a "No Command" message and a picture of an Android lying down. The device won' turn on or even show a sign of being charged. There was nothing unusual before I tried to restart it! Please help me by providing a tutorial.
