Beaups' frustration is justified. Imagine (or consider, if this is your actual situation) you have a kid with a toy that has a tiny blue light on it, and your kid says to you "Daddy (or mommy), I want the light to be red!" So you take the thing apart, find wiring diagrams, meticulously unsolder the blue light, solder the red light, reassemble it and say "okay kid, there's your red light! Just don't drop it in the water." The kid is happy for a few days, and then sure enough he comes back and says "I dropped it in the water! Can you make the red light come back?" So you disassemble it again, find out what is fried, order a new part, break the new part because you were wrong, order a few more parts, find the right one through trial and error, install it, reassemble the toy and give it to your kid. "There," you say, "the red light is back on, but don't throw it in a fire." A few days pass..."I threw it in a fire! It's all melted now! Can you make the red light come back on?"
Wouldn't you kind of want to smack your kid at this point?
