iPhone not syncing after new dock connector installation

I have recently installed a new dock connector for my iPhone 4s. My iPhone was experiencing the "no sound bug" that happens when docking the device with a device such as a speaker system or car USB port. This was remedied after installing a new a dock connector that I purchased.

But now my iPhone will no longer sync, wired or wireless, nor show up in windows explorer (running Windows 7).

I have followed the advice here: http://support.apple.com/kb/ts1538

I have had no success. I have tried multiple cables which I don't believe are the issues since they charge just fine.

As a test, I replaced the new dock connector with the old one and lo and behold, it connected to my PC and synced, but as mentioned before, it will not play sounds from the speaker, only headphones, ringer, and siri work with this bug apparently.

Has anyone discovered a solution besides the aforementioned for this?

It should also be important to note that the iphone does not show up in device manager AT ALL with the new dock connector. Not under Universal Serial Bus controllers nor Imaging devices. There are no "Other Devices" or "Portable Devices" categories listed on my Device Manager.

Is it possible that I did not install the new dock connector correctly? If so, why then would it charge when plugged in but not show up in explorer? During the replacement of the new dock connector back to the old one, I noticed that the home button cable appeared slightly loose, but this was due to the new dock connector cable being poorly manufactured because the latch does not sit symmetrical on the cable. Do I simply need to purchase a newer dock connector? If so, does anyone know where to buy OEM iPhone parts because I suspect this is largely the problem at hand.

Thanks for any feedback you can supply.

Actually as a follow up to this, I had replaced the purchased flex cable with the original and used a pin to clean out the charge port. Guess what? It magically worked. I am 100% convinced and I can even prove and replicate the problem, because it is due to plugging into devices that are not official Apple products. Such as: the USB connecter in my Honda Civic 2010 and my TEAC speaker system with iPod/iPhone dock. Upon connecting to the device, it somehow shorts out the charge port, specifically the pin (of the 29-32 pins) in the connector that enables synchronization. As a matter of fact, one of the pins in the old charge port even broke off but everything still works, including sound playing from the speakers, headphones, syncing, etc. I could even plug it back into my car or speaker system if I was crazy enough to try it again, but I am content with it working for now. I'd recommend anyone else with this problem following in my footsteps to try cleaning out with a very thin pin or replace it.

If replacing doesn't work as it didn't for me at first, Anton may be right so I would buy from a place that will accept returns/replacements. I would replace it immediately upon receiving so you don't waste your return period and keep replacing. A good idea may be to even buy an old iphone off ebay that is guaranteed to sync but perhaps has other issues like a broken screen or camera. This way you know you are getting an original iPhone flex cable manufactured by apple. You may also need to purchase a full set of screws for your iPhone as I have come close to stripping some screws as a result of taking apart the iPhone so many times. It is hard to believe that after all the hard work, it only took a small sewing pin to pull out the broken connector pin that had blocked my connector port, along with other debris. I hope this helps many people because I know many people on the net have had this issue. Too bad Apple no longer helps their customers.

There are a lot of crapy parts for sell.

Get another chargeflex and try again.
