My 18 month old chucked my BB from the couch yesterday afternoon, it bounced off the wood coffee table and landed on the carpeted floor. Few signs of life since then It does nothing when I press the buttons, plug it into the wall charger. It's attached to the computer by usb now and keeps blinking on and off (shows a white screen with a battery/lightening bolt) but nothing else.
The white lightning symbol usually means the phone isnt registering that the battery is in. Take out the battery and put it back in to make sure it is seated correctly.
I'm not sure how to fix it exactly. usually i just let it charge for a day then do a system wipe/restore. If you get this one working or IF you need a new one (lets pray it doesnt come to that), I'd suggest getting this like i did
