My home button was not clicking properly leading to tears of frustration whenever I had to click 5 times to get back to the home screen or the multitasking bar.
I received the home button and thought I'd wait a few more days but after my poor thumb got tired of the extra clicking, it was onto the repair. I printed out the template which helped keep all the screws and various parts of the phone organized.
I unscrewed and took apart everything, put in the new home button and put everything back hoping that I was not pinching any wires or anything. Switched the phone on and yay...... my thumb gave a big sigh of relief, 1 click to the home screen and 2 clicks for the multi tasking.... :-)
I put some double sided tape on the template so that the screws would not roll around.
Also when I saw the initial tutorial I was like no way can I do this. But if you just take it one step at a time it goes by fast.
Make sure you have good lighting i had a headlamp on my head and my halogen lamp on.
