Q: need help!

It's too late. Your data is undoubtedly already gone.

You will have to force the phone into recovery or DFU mode and restore iOS. Anything that wasn't backed up before it crashed will be lost.

- Try another cable   

- Try on another computer   

- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
