Did you start the service with "sudo adb start-server"? – nastys Nov 12 '13 at 6:26

It seems that ADB is not detecting the device...

You can try entering "fastboot mode" by turning the device off, holding Vol Up + Power, and then trying phablet-flash.

If this does not work, check your USB cable and research how to place your device into Fastboot mode.


Boot up your phone, enter Settings, enter "Development Menu", and enable ADB. I believe the installer uses Fastboot. If the above method fails, try this way. Also remember that you need your bootloader to be unlocked:
