Hope someone can please advise.... N900 was working fine...or at least appeared to be.... I shutdown N900, but today when I tried to boot it up, it seems to get 'stuck' at the part where the screen is black and you see the horizontal row of several blinking tiny little white dots. Have waited for quite awhile for it to get past that part, but it doesn't, seems to get stuck there and so display doesn't change, just see the blinking white dots... Any way to 'clear this' or do I need to reflash? Thanks!
