STM32F412G-DISCO Blank Screen Problem

[Linkpad]

Hi, I have tried programming and resetting this discovery Board but all I now get is this fuzzy grey screen as shown in the image is there anyway to do a hardware reset or is it a programming error? I just either want to reset the board back to its default state with a touchscreen menu, or a simple TouchFX example to work...

Thanks

You can't "reset" in the sense of a button, you could perhaps have saved off a copy of the internal / external flash content before you over-wrote them, and then load that back via STM32 Cube Programmer, and the right External Loader for the board.
