Hi Guys
Got the same problem this morning and didn't panic but began to google for a solution. I couldn't find a suitable one (but haven't even searched that much...) but I finally SOLVED IT and got my BB back working.
1. BB with wall charger, no image, no led
2. removed battery and plugged wall charger again: after few secs, got the red led and battery image with a red cross
3. unplugged, put the battery back on, red led immediately switches on
4. plugged in wall adapter: BB is bootstrapping
5. BB up&running!

Cheers,
Alex
