The motor controller chip is damaged. I was hoping that the damage may have been restricted to the two TVS diodes in the bottom right corner, in which case the simple fix would have been to remove the shorted diode.
According to the following guide, a "chip transfer / swap or similar services could be required for newer [Samsung] models".
Unfortunately in your case there is no discrete flash memory IC. This means that, if a straight PCB swap does not work, and if "adaptive" data need to be transferred from your original PCB to the donor PCB, then you will require a "PCB adaptation service". The above vendor provides such a service for free.
