I don't know what I can do after full chip erase

Hi, I have a STM32F407 Discovery Board and I'have made full cihp erase. But I have no idea what I can do after doing this. In the communtiy I have read that I have to install the original firmware. How can I do that? Can you help me? Thanks from now.

I did what you said step by step, but after clicking 'build' I get this error.

Attached a complete project from which you can try the example.

Go to F4_Discovery_Example\Projects\STM32F4-Discovery\Examples\GPIO\GPIO_EXTI\STM32CubeIDE

If it doesn't compile, unzip the folder under your root drive C:
