I am challenged with my nwhd5 - it is alive - the backlight responds when I press a key - but I can't get the arrow keys to actually DO ANYTHING. So I can't move between menus - select songs, etc - and I was thinking of updating the firmware - basically trying to re-init the whole device - but you have to be able to get to the options menu - which is impossible to select. Any ideas how I force the device to re-initialize?
