Recently i wanted to test android L. So i installed mulitboot and then installed android L to a USB stick (OTG cables). it boots 2 times fine(booted to my primery OS fine multiple times). so i just booted to android L it was very slow so i deside to shut it down and go to my regular OS. so i press showdown then wait a few seconds, remove the OTG cable and try to boot phone, nothing happens, at all.
Windows shows google nexus ADB interface, but if i go ADB devices it shows no connected devices, the same with fastboot devices.
Nothing happens if i press any combinations of buttons.
