SKR V1.4 Turbo died when 3.3V and 12V shorted

[baymax2161]

Hello

I just got the SKR V1.4 Turbo board and was testing it on my 3D printer. I accidentally shorted 3.3V pin to 12V with a screw driver and the LPC1769 seems to have died.
Could I just replace the LPC1769 and get it to work again? I have the soldering equipment and experience required to replace that chip. But I'm not sure if it has some sort of bootloader on it that I need to flash first.

I'd really appreciate any sort of help and suggestions.
Thank you.

Sure that not the fuses are burned?

After replacing the CPU, you must load the bootloader
