I am trying to put an atv image on a h9s. I formatted and used the same usb stick that I have used previously on a h52s and a h2s with no problems. This model does not have a front power button to hold down when power is turned on at the rear. I have changed the noforce to force in the files on the usb. How would I know that if it is reading the usb and should I expect to see an atv image. at the moment I have no output from the box and do not know if I have to wait then turn off then back on to see the image.
