Hi Andy,

I have the same problem on my n810 with two different batteries (genuine Nokia, and a SCUD). A reflash did not change the situation for me either. It would typically take me a good handful of tries to get my n810 to boot past the blue and white "Nokia" screen. Now I have found that taking the back cover off, removing the battery for ~5 seconds and then reinserting the battery slapping it into place a bit more forcefully than normal seems to get it to boot on the first try.
