No audio? Replace the headphone jack!
I managed this in about an hour to fix a broken "volume up button" and combined with replacing a broken ringer/mute switch. Thanks for the guide!!!
Two very minor comments to consider:
- Step 19 indicates three 1.8mm screws and one 3.8mm. In my 3G i found the middle "1.8mm screw" is actually smaller. Hopefully this helps someone who didn't notice that on the way out...
- Step 14 doesnt mention the flexible clip that is attached to the logic board and fits under the bezel on the right hand side near the dock connector end. Most people will find it anyway, but it might help those like me (who are pushing the limits of their technical skills) to note the preferred method for handling this. I just moved the logic board towards the opposite side and popped it out with a screw driver...
These are only minor points but overall i found the guide to be excellent and much easier to follow than anything else i found including you tube videos etc.
i broke the little tab in the bottom of the main board, now my network service is always low, its connected to the signal right? is it okay to solder a piece of wire there so that it can touch the metal bezel?
I replaced this part successfully but my phone still thinks it's in headphone mode. There is obviously no lint in a new jack so plugging/unplugging a set of headphones isn't working. What else would cause my phone to only have sound with headphones plugged in?
When you get back to this step as you are reassembling it, it's tempting to test that you've got all the cables plugged in properly by switching the phone on and testing it. However the Home button will not work until the front panel is back in position, because the electrical connection is done by a pair of touch contacts which only work when the phone is assembled.
