I've upgraded mine hdd070 using GoGear software supplied by philips. Then I got message unplug the device. After unplugging the device, the device showed the message for a while. But when I started again, it shows the PHILIPS logo on the screen and freezes at that time. I tried soft shutdown by pressing the up arrow and +volume key together (which is used to shutdown the device). But does not solve my problem. Anybody can help me out of this problem. Thanx.
