Please join and provide more information in this thread.
1) How are you charging your phone
2) How long have charged your phone
3) What errors are you seeing?
4) Presuming you are not seeing any errors - basically the phone is not starting, can you do a soft reset or feel it vibrate by holding the volume down and power button?
