Having trouble with BB curve. Was acting up so I did a battery pull. After that BB would not boot up. All that it did was the led would blink red. Let it sit all night without battery and tried again. Did the same thing. Did 50 different things and finally got it to boot up. Now any time I do a battery pull does the same thing.
Then this appears to be OS corruption. two things you can try.
1. wipe the device and sync your device. I would not restore a backup as it might bring the problem back. THis may not work if the device will not boot.
2. Re-install the OS if above does not work. This will also wipe the device. then sync your data back over from outlook.
