iPhone 3G start problem
I got iphone 3g and power button was stocking and not work realy great so I deside to open my Iphone and try to clean it from all that dust and hope that it will help. When i open it i remove cables 1,2,3 and 4 but didnt pay atention on cable 3 lock but it slide easy even without unlocking it. i clean dust from inside and dock connector from outside. After that i connect all cables back and assemble it back to original but now it do not start at all. I was running out of battery when i satr my operation so I think it run out of batterny by now but when i put it on the carge nothing happened, my pc do not recognize it. I try to make it vibrate by putting it in mute but nothing. Maybe i somehow broken my dock connector and because of empty battery and broken connector it cant charge, but how I can know for sure? should I change part by part and try it? any help please! I am realy sorry about my bad english.

I would carefully open iPhone and reseat Flex Cable #4. That is the dock flex cable, needed to charge iPhone amoung many other functions. Also, not opening the Tab on #3 could have damaged something, most likely the #3 Flex cable itself. Damaged #3 have been implicated in non-booting iPhones. If the #3 Logic Board Connecter is fine and you dissconnect Flex #3, iPhone will boot fine, but if you connect a damaged #3 Flex then sometimes boot problems occur.
Anyway, first step is to carefully reseat Flex Cable #4.
I have try multiple times reset connectors 1-4, with no result. what you meen with mega battery drain? do you meen that if pin 3 is damaged it may eat my battery that much that phone cant start even while charging?
exactly what I had.. the pin on the right which I think is audio in or out had been damaged and was draining the battery. Once that was straightened so that the flex made proper contact the problem went. Just don't do what I did and try to fix it with the board still on the battery...phone went into hibernation and I thought it was dead! use a plastic tool.

when the battery is dead itunes will not see it and you can't charge..measure the output on your battery using a multimeter..les
so 9v battery to 1 and 4 pins for 10sec then 9v off,cables back on and try charge from usb cable? how about + and -? is it like + on pin4 and - on pin 1 or how?
yankees, I'm sorry my multimeter is without battery so I can't tell you which is which for definite.. I looked at all my old batteries and they do have a + and - on the battery itself but not on the pin..
