After repair, won't charge or connect, proximity sensor also busted.
Hello community...
Brief description. After disassembling (iPhone 3G black 16GB):
- Proximity sensor is busted.
- Ear speaker won't work.
- iPhone won't display battery is charging.
- iTunes will not detect anything.
- If plugged to the computer/wall while off, will turn on.
- The phone actually charges if plugged, but extremely slowly (powered off it goes faster).
Long description:
I had to replace the headphone jack + ribbon on my iPhone 3G. Therefore I needed to take most of it apart.
When I put it back together, the headphone jack worked great, but there was no audio on the ear speaker. I realised I busted my proximity sensor once I made a test call, put the phone next to my face and the display didn't go black (plus the ear speaker didn't work, had to talk on the speaker or headphones).
In addition, I noticed nothing happened when I plugged it in the computer. The battery won't charge and the iTunes won't detect a thing. If I plug it in while it's off (computer/wall), it will turn on.
I'm buying a replacement proximity sensor with ribbon cable to fix that bit, but I have no idea what to do with the battery issue. Everything seems intact in the logic board, I've checked for the SMD thing as described here.
Any suggestions?
UPDATE
I've fixed the description of the problem to include my new findings.
UPDATE #2 02/July/2011
I have replaced the proximity sensor and the dock connector to no avail. Same problems, which makes me believe it is something related to the logic board. I took the phone to Apple, but they refused to take it in for service because the phone has been opened. Any new ideas?
Esta é uma boa pergunta?

I forgot to mention that I might have accidentally turned the phone back on before reconnecting the front part (i.e. connectors 1, 2 and 3) if that's even possible. I did test the power button a few times and, after replacing the screen, nothing would show up. Because the phone did vibrate when I moved the mute switch, I realised it must be on without anything on the display. So I reseted it by pressing home and power for over 5 seconds and then turned it back on by pressing power alone. That's when it came back to life (with the problems described above). That said, maybe I touched something with the phone on and open and short circuited something that damaged the logic board and caused the software issues I'm having? just some thoughts...

Any iTunes updates recently or jailbreaks??

No. The phone has been running a stock 4.1 (8B118) on 05.14.02 (O2 Locked) for quite a while. In addition, I did test my computer setup with a new iPhone 4 and everything works... it's definitely the iPhone 3G (hardware+maybe_some_software).
