Backcourt or not?

[OfficialBFish]

High school tournament today. Player A1 is dribbling in the backcourt, tries to throw a long, hard pass to a teammate. The pass is so high and overthrown that it hits the backboard, bounces a few times, and comes right back to player A1, still in the backcourt. My partner originally called backcourt violation, but after a discussion, we decided that since it hit the backboard it should just be ruled as a try and that team control was lost and regained legally. After the game, I really started to question this call. I'd think that just because it hits the backboard doesn't make it necessarily a shot attempt. So my questions:
1. If he clearly wasn't shooting, should it really be looked at as a try?
2. Does hitting the backboard give the ball front court status? Would it be backcourt violation?
