You should install becomeroot from the application manager under settings menu on n800... if you dont see it then click this link (from n800 browser) to add the repository which contains it by searching for becomeroot here : http://www.gronmayer.com/it/ After you have installed it then open xterm and type : sudo gainroot passwd root then set your root password, preferably to something you will remember With SSH access you can remotely access the entire device from a destop... i would recommend eventually learning this. Install SSH Server on device and a utility like WinSCP for Windows XP or gFTP for linux. You will need to configure WinSCP with the IP address, username (root) and password. If you dont know the ip address of device, install IPHome applet.
