First to answer JCNapoleon, Looks like you will have to buy another flex cable, otherwise its finished. try inserting the cable very well because it can be that also

On to my post to this. its been about 2 months since I saw this because I bought the iPhone used in January and everything was perfect except it wouldnt charge from my old data connector, just the one that came with it. all other docks were a fuss

then all of a sudden. Nothing couldnt charge. I Was starting to panic because i realized if it was a hardware thing this would be impossible. Took me a few days to understand what the problem was exactly so once I got that I ended up searching for threads related to the problem and hope i could find tutorials to the exact problem..apparently I only had guides to open it but nothing close to replacing a flex cable. I only had 1 guy that had done it through emails so once then I was motivated enough to go ahead and do it.

And about my skills.....heh I only love computers and electronics in General. I am only 17, but have built enough PC's and fixed so an so so this is pretty much new to me, only soldered once in my lifetime so if anyone does this, TAKE YOUR TIME!!!!!!!! take steps, coffee breaks anything.


I have pictures as I went but i pretty much go to the point after i replaced it



Old flex cable with the mic area is laid on my pinky (I tried to desolder the mic but it broke without hesitation....lol)




New flex cable installed with internal speaker soldered on






And this is my fresh FRESH Aluminum house casing.....bent I simply could not get the dang thing off. and showing is the old mic. both pins are broken off


Here how much it has bent and probably one of the best pictures I have taken lately




These tools no longer are usable...they are eaten up by this phone




And my lamp to help me



So yes, one1 your images helped my very much get to where I need to be to get this replaced. Couldn't be any happier to have it fixed. took a few days to be complete as I had to wait for the mic to arrive in the mail. I did solder it on barely and damaged the mic a bit so the first few weeks people couldnt hear me at all on conversations, but eventually it just sort of got better Like real surgury heh.

Here it is a few month after its horrible moment. still running strong. Although my Wifi and cell antena cables are weird. I have a lower range to find signals than before and sometimes cut off. same for the service.







Have a nice day

Best Regards

Would it be possible at all for you to write the necessary steps to replace the flex cable down? I know you have already said that it would be almost impossible for anyone without knowledge in this field of electronics to complete this procedure, but I have nothing to lose anyways.

This thread details my problem, and my fruitless attempts to resolve them.

Thanks.

Good job up there guy!

and to you, I doubt this is your issue, but if you wanna tear it up with nothing to lose.... might as well try. I've done so many I can break them down and build them back up in 30 mins.

I've already disassembled the phone. The pieces are in a shoebox in my drawer, unable to be operated on further. After I took it apart, I discoverd that the flex cable near the home button was ripped, and so I made my way here. Unfortunately, I have no idea how to do this. xD

[one1]

It can't rip sitting inside the frame it ripped when you pulled the MOBO up off the frame. It's taped to the frame.

[JCNapoleon]

Well, I kind of gave up on this. I replaced the flex cable twice and both times the HOME button still didn't work. So I bought me a 3G on the street and jailbroke it. Just for the hell of it, I took the iphone with the bad HOME button to a place they repair them and the guy said he will fix it for $40, according to him, it's the whole HOME button mechanism is bad,...LOL The HOME button is just the flex cable and button, personally I think he's full of it, but for $40...I'll let him take a crack at the MECHANISM....

[one1]

There is no mechanism. When you bend the home button cable back to wrap around the plate it cracks the connection if you don't do it correctly.

Hey I sent you a PM about a week ago, so that didn't seem to work. I need to get my phone fixed, there is a thread in this section about it if you need more details. Just tell me what I need to send you, where to send it to, and how much money you want for the job and I'd love to do business ASAP.

[enriquesdrj2_8]

yea there could be some new problems when this is done. My Wifi and regular antena's arent working to well, the Wifi especially. Hopefully its just loose wiring. But I guess I will take a look at that once I get the renovation started on this baby over the summer.

Does anyone know where to get the better quality of flex cable for iphone 2g? If there's a certain way to install it, please let me know. A guy look at my phone and said the communications board is bad, I guess he means the logic board. I found used logic boards on Ebay for $80, but there's no way to tell if they have the same HOME button problem.

all i can really make out is that that tip is somewhere pretty dangerous...

maybe if i had an iphone to open i could make more sense of it ... havent managed to get hold of one to open yet....

But, yeah, the thread doesn't even say which phone is for.

For people who have never open theirs, it's kinda hard to tell because the only pictures are of the insides.

Anyway One1, my brother replaced his glass/digitizer on his 3G and now his mic only works when speakerphone is enabled. Sound like a flexcable issue to you? He used the phone with the shattered glass and it didn't have the problem before taking it apart.

Yea either

1. It is probably the flex cable got torn and u need to replace it
2. the flex cable somehow got out of its socket slightly so there is conflicting issues
3. There is always restore to me that can also fix it maybe
4. worst case being the logic board died. But i doubt it since it was just the screen and digitizer so im going for 2, and 3 that I said. Good luck

Dear Sir,

I cannot figure out what are you doing with the microphone in figure 9. How do you connect the new flex with the mic??DO you have to heat the old cable to be removed??Any help would be greatly appreciated

[JCNapoleon]

Kondylak, my best advise is to replace the whole midboard, I bought one from Ebay for $34.00. This will have the flex cable, the wi-fi antenna, the mic and speaker, you just have to mount the screen and motherboard to it. I've replaced the flex cable twice and both times it torn no matter how carefull I was. If you want to experiment, you have to remove the mic from the old flex cable with a soldering iron, then solder it to the new cable. (Too much work, my friend). I've replaced the midboard and my iPhone came back to life, thanks to the advice to the people in here, specially to ONE1. See attached image of the midboard.

Hey guys,

after seeing your marvellous pics, I decided to fix my iPhone's broken mic. I did not have prior experience regarding this and surely enough, I tore the flex cable in different places . So if you are thinking of opening your iPhone without strong prior experience, you can already order the spare parts because you WILL break it (just repeating ONE1's advice, but coming from a different perspective :P). That's in my experience due to the criminal amounts of glue Apple use.

I will shortly be in possession of a new flex cable and mic but I am unsure as how you should solder them together. By looking closely at the broken one I have, I am deducing that the shorter part of the microphone (see picture 1) would be facing outwards (towards the dock connector, in the direction the pen is pointing) such that the microphone protrudes very little outside the flex cable. Cable shown in picture 2.
So is this direction right?

Also, when soldering do I need to make sure I solder the two pins separately? I know it sounds obvious that I should, I just want to be 100% sure.

Finally, do you guys have any advice for soldering the mic? A special way that could make it easier? Or anything I need to know to solder it correctly?
