Recently I dropped my iPhone, breaking the screen, so I had that replaced with a new screen by myself that I brought from Amazon.

Now that I replaced it, the iPhone home button doesn't work at all because when I press it, it doesn't do anything, no matter how hard or many times I press it, it still won't do anything.

Later on, I took apart the iPhone and replaced the home button with a new one, and this didn't solve the issue and yet I don't know why it doesn't work at all.

I have pictures of my iPhone 3GS, hopefully it should help or whatsoever.

How can I get the home button working again?
