# Flashing # To flash a device, you will need to use `fastboot`. Place the device in fastboot mode either manually by holding the appropriate key combination at boot, or from the shell with $ adb reboot bootloader Once the device is in fastboot mode, run $ fastboot flashall -w The `-w` option wipes the `/data` partition on the device; this is useful for your first time flashing a particular device, but is otherwise unnecessary. # Emulating # To run the emulator, type $ emulator
