Apm 2.8 deleted program

Hello, when I tried to update the firmware of the board apm 2.8 I deleted the internal program through the aduinoIDE however I have researched enough to solve the problem and revive my board apm 2.8, I would like someone to help me in this situation because I was super fascinated with this project and at the moment I want to give up…

Unfortunately this hardware is no longer supported, this is why I changed the post type.

There are lots of FC avsilable , just look at the wiki
