My Lattepanda is dead. please help me

I was trying to make circuit for my research by using 12 voltage.
(Lattepanda power is 5V)

and I made mistake that contacting 12V Vcc and Lattepanda GND (short)

and 5 sec laterm lattepanda turned off.

and it doesn't turn on.

if it flows overcurrent or overpower, It can't be repairable?

and tantalum capacitor gets very hot.

If there is any solution please reply..
