so u say that your blackberry is only lighting up a red light well that happened to me, but i fixed mine okay go to your blackberry desktop manager when it opens plug in your blackberry okay it says disconnected go to application loader and click update software leave ypur blackberry pluged in, i know the the desktop manager says disconnected still run the update software click okay this could take some time but after the update software is finished your blackberry should work again and should say connected.mine had the same problem but i fixed it this way.
