i posted earlier how i used the wrong firmware for my eurovox max V. my box went to standby and i couldnt power on. Heres how i fixed it. Take power cable out. Open up the box. On the green panel there is a small reset button. Connect your null modem cable and start to upload the right firmware( you want to see the " waiting for receiver" message) Press down the reset button. While holding down reset button connect power cable after a few seconds release reset button and your upload will start. Hope it helps!
