I believe you already tried this...but just in case...pPlease try this sequence...note that, throughout the entire 4h15m process, your BB must remain connected to a known-good wall charger (not PC USB):

1. With the battery inside, connect your BB to the wall charger
2. Leave it alone for 2 hours, no matter what the LED or the display does
3. Remove the battery
4. Wait 15 minutes
5. Insert the battery
6. Wait another 2 hours, no matter what the LED or the display does

This has been known to "kick start" some BBs.
