I haven't found an answer to this by searching so apologies in advance if this has been asked before and I'm just not finding it.

I have an N770 which I'd installed Mplayer on ans was streaming video from my PC to the 770. It hung just after it started playback and the only thing I could do was remove and reinsert the battery.

When it then rebooted, i have an almost white screen. I hear the Nokia sound as it boots and as I touch the screen It clicks but I can't really see anything except a few faint shaded areas that run down the screen . In PC terms it's reminiscent of setting a higher display resolution than the screen can handle and you get those garbled line images. My 770 is similar except that I'm clicking blindly on the screen.

Being a Windows person I tried running the Nokia internet tablet software upgrade wizard and hoped it would reinstall the whole file system and sort out my problem. It didn't.

Can anyone give this poor non linux user an idea on how to fix this
or at worst do a total reflash of the full file system so all I need to do is reinstall my apps.

Thanks to anyone who can help!
