I have a similar problem except that I have currently bricked my tablet. I used a dealextreme CA-101 cable. Obviously a copy, not an original. I presume there is something in the Nokia cable that is different from the copies.

All I get now is the white screen and the Nokia logo. It won't do anything else (except dim after a while). This happened during the flasing process, and I got an error messge about the USB cable being disconnected or something.

I have a friend who will hopefully bring her Nokia cable in tomorrow and I'll see if I can make any progress.

Any comments that might help us?
