Fried arm mcu

Hi, a friend asked me to fix his form1+, that is not powering up anymore.
he opened it and placed the wrong screw at a critical place, the screw was too long and hit the board and shorted a trace that is going to the mcu.
i suspect it to be dead or that the programmation has been damaged.
i can replace the chip but is there a way to reprogram it ?
i think i can physically do it through jtag connector but i need the code.
Or is there a way to do that through usb? and firmware upgrade with a blank chip?
thanks for your help,
