More information may help get advice. What model? Does it register when you attach the phone to a computer? Does it boot when on a USB connection? Were there any signals before the end?
It was left for charging over night and I woke up with the phone not powering on. The model is a blackberry bbold touch 9900. The red LED light flashes slowly. I have not tried connecting it to a computer. I was thinking of handing it back to my friend, however, if i can fix it i will keep it. Really need help on whether I can fix my problem or not.
