The Home button stopped working properly... the iPhone would act like somebody was pressing the Home button while it was playing music even when nobody was touching it...
The repair and the process was - interesting. Firstly,I have to give credit where credit is due... having the right tools for any job is essential and the iFixit provided the perfect tools... and the instructions guided me through the process.
I read the Home Button repair would take about an hour... but by the time I got to removing the top cover - somewhere around step 25-30, I was already in it for over two hours.
Then, removing the top cover took another hour just by itself... somehow my top cover was caked on and there appeared to be some kind of adhesive... it just took forever to pry one corner up enough to get the tool in. I think it took a long time partly because I was trying to be very gentle.
Secondly, the number of teeny tiny screws is surprising.
I had two problems that I didn't realize I had until it was too late.
#1) I didn't realize there are two different lengths of stand-offs.. I put the longer one into the wrong place and then it broke in half when I was trying to unscrew it.
That meant that I had two standoffs in the wrong position and that prevented two more screws from being reinstalled correctly.
I don't think this contributes to any operational issues... but I really have no idea what the long-term ramifications of this might be.
#2) The instructions clearly state that when reinstalling the top cover, it is essential to make sure the connecting cables are threaded through properly - so I took extra care to make sure I did that. #epicfail.
Unfortunately, I got all the way to installing those cables - another hour of reinstalling little screws and the logic board before I found out that in fact, I did not pull screen connectors through enough.
So, I was faced with a very difficult decision - a) uninstall the logic board again (another hour) or b) try to pull the connector a little so it would seat properly. Since one of the standoffs was broken and it didn't look like I could remove the logic board again, I opted for Plan B.
Now, at this point in the story, anybody who knows anything about iPhone repair is shouting at the top of their lungs, "No, no, no!!!"
Issue number three was one of the four corner screen screws was at a weird angle and I could not get the screwdriver to seat enough to turn the screw in - so that one just got left off.
Good news - bad news... the bad news is that corner is not tight... good news... if I ever need to get the top cover off again there's room for the tool now.
In the end of the end, almost everything works... the iPhone powers up; the screen is clear and bright; the home button works flawlessly - no phantom pushes... bad news is the screen is totally unresponsive to touch.
Final Analysis: iFixit A+ / My repair capability F-
1) get the plastic multi-compartment tub to put the screws in and label each section with the step number so you go back in the way you came out... whatever that costs in time and materials is worth it.
2) go slow, be patient... be prepared to walk away in the middle of the project if you feel you are getting frustrated and/or tired.
3) get one of those lighted magnifying lamps that you can look thorough... the more you can see what you are the higher your chances of success.
