If the device is in power-OFF state and you connect it to computer, before it wakes up NOLO will check for flasher connection, and if it exists then flasher gets priority. If this does not happen there are 2 possibilities: 1.) Your flasher is not getting access to the USB port 2.) Your device is not in real power-off mode For problem 1, you need to fix your PC For problem 2, you might want to try to press and hold the N9 power button for about 30 seconds or until flasher notices that the device is connected when you plug it in.
