The requirement for electronics knowledge and skills is a clear dividing line for me.

I've recovered and hacked devices for friends using software. Especially phones which have recovery functions I can use but I've also hacked some older game consoles. I can't do anything if electronics skills are required though. At that point it becomes specialized repair work.

I suppose nothing's really bricked if you're smart enough. Just desolder a chip, reprogram it and resolder it back in? I don't know how. I tried to learn what I could but it turned out hardware is a lot harder than software.
