Two options I would say:
1.) Delete the video that was created if one was created.
2.) Create a back up file and master reset the BB; Settings>Options>Security Options>General Settings>menu key>Wipe Handheld.
I like your use of the BB as a flashlight. I have done that a few times when power goes out in my house. That is a funky problem, good luck!
