Default Star s9500 wont turn on

Hello,

My nephew formated his star S9500.

when i plug it in the usb i can see it in device manager com ports but it wont turn on.

i cant see preloader in other devices.

i have tried mkdriods, flash tool and pda

can anyone tell me how to get it to turn on without this i cant put a new ROM on.

thanks in advance
