Flashed x50 with latest bios, not charging anymore

[Friko]

Just flashed x50 with latest bios, now it won't charge when it's powered on while sitting on the cradle.

It does charge when it's switched off though. Any clues?

Not sure what ROM you flashed, but charging when off and not when on indicates not enough power. I get the same thing when using a sync cable. First thing I'd do is check the power connection to the cradle.
