Did I just fry my FFL L50?

I inserted the 18650-battery the wrong way around and screwed it closed. It smelled slightly like something burned. I cleaned it with isopropanol. The transistor at the blue arrow has a different color and is sticking out. And the part at the yellow arrow looks burnt to me. Can this still be repaired, maybe by replacing individual components, or would the entire board need to be replaced? Has anyone fixed this kind of damage before?
