A3100 dead, how to resurrect? Поделиться Опции

I'm sorry for writing in English, and also for the noob questions.
I have an A3100. When I was using the Ghost tool to restore a bin file, the phone suddenly turned off. Maybe the battery ran out. I could not turn on the phone (battery was fully charge). When it is connected to PC, the port COM does not appear.
Was the power source IC dead? Is there any way to resurrect it?
Thanks!!!!

I think it's not cable or battery.
Before it dead, I could not enter Download mode without battery.
I've changed the cable and the battery, but it could not be turned on.
I'm now looking for the way to activate the connection to PC. It may be the test point method or qualcomm hardware connection.
