iPhone 1G Home button

Flag Reply by rcrabtree Feb 23 @ 11:08 AM

I am attempting to find out If I should replace this part and if there is a guide on doing so.

iPhone 1G Charging & Click Jack Ribbon Connector.

Here is what has happened to my phone

My 1g phone fell out of my pocket and now the home button is completely unresponsive. Everything else works except for the home button. Also I received a phore call and the person could barely hear me. I had to scream into the phone.

I docked the phone and reinstalled the software. Nothing has worked and the phone is not jailbroken.

It is an original and not under warranty. Can anyone recommend what I can do to fix this?

I just removed this cable from my first gen (1g?, 2g?, how about pre-3g?) iPhone and it is an absolute bear. I am currently waiting on my new flex cable to arrive. In my case I believe I damaged the cable when trying to insert it back into the logic board without undoing the "latch" on the socket (doh!), such that my phone would not charge any longer.

In your case I would suggest:

Since the microphone AND the speaker AND the home button went out, MAYBE just removing and re-seating the flex cable into the logic board socket would fix this. If your phone did not fall into water, it seems unlikely that you could break all three devices at once. But on the other hand I would expect you to have charging and syncing problems as well, and it sounds like you do not. (Just don't forget to undo the little black latch on the socket when you go to re-seat the cable!!!)

If re-seating the flex cable does not do the trick, and you have to actually replace the cable, then like I said, it is a bear. You will probably want to buy a new microphone, since it is soldered to the cable, and very tiny. The speaker is also soldered to the cable, but it looks like this could be desoldered with some care. The plastic case assembly at the bottom of the phone that houses the button, mic and speaker has many plastic tabs and lots of double sided sticky tape holding the top and bottom covers in place. I broke several of the tabs opening it up. I do not know of a source to purchase replacement top and bottom covers, so I will just have to reuse my slightly mangled ones, but that should be OK.

It would be great if we could purchase a complete "middle chassis" assembly, with the mic and speaker and flex cable already installed, but I have not seen this for sale, only bare mid-chassis. Of course there is always the salvage phone route.

When I realized I had trashed the flex cable, I bought a replacement phone off of ebay. If I manage to fix my phone I will just resell my "new" phone on ebay. But this is not a quick repair if you are not already set up to do it.

Hi

It seems you have managed to resolder the mic to the iphone. I am about to do this with my phone but I don't know which way it has to be soldered (which pin to which contact point...) Could you tell me this? thanks!

I'm sorry but I have not done this...yet. Don't even have a replacement microphone in hand yet.

But I would expect that the "polarity" of the microphone would not make any difference, unless it requires DC power. But I guess it is possible it is some kind of powered microphone. The way to test that would be to apply a DC voltmeter across the two leads that attach to the microphone while the iphone is powered on (and maybe while the microphone is accepting input). Of course if it is powered this tells you it has a polarity, but not which way to install it.

Does the new microphone appear asymmetrical to you?
