I dropped my iPhone 2G and have the same thing happen to my iphone 2g. First earphone jack wouldn't work when I plugged in the factory earphones then when I tried charging it with the usb connector, it wouldn't respond. So naturally the battery ran out. I've taken it apart and everything seems in order. Since I have my iphone open, can I charge the battery somehow with an external power source (power from a stripped usb cable?) Also does anyone know which part of the iphone I should look into replacing?

The headphone jack should be replaceable, but im not sure, also, make sure the battery is properly grounded, i had this problem in my 5th gen video, and reseating the battery seemed to do the trick. but the headphone seems to be the problem

Here is a solution, Plug your phone in with an A/C Wall Charger and do a hard reset. Hold the Home Button and the Sleep/Power Button until the comes on and reboots.

A usb cable will most of the time not get it to come alive. So try the charger.

Quote from djdevinleet:

I bought an iPhone 2g 8gb off of ebay a couple days ago. It was supposed to come with a charger, but it didn't so i picked one up. When i plugged it in it came on and a battery almost completely empty showed up with some red on the left side. I don't know if it was flashing or not. I went to tell people it was working because i didn't know if it would. When i came back, The iPhone was blank and wouldn't turn on or anything. I tried holding the sleep button and home button. I tried different combinations with no success. I tried using my friends wall charger with an LED and the LED does turn on when i plug it in. I left it in for 12 hours on the wall charger, no success. I left it plugged into a usb cable that's connected to my pc for at least 24 hours with no success. I'm wondering if someone might help me tell me the problem. I really can't afford to buy a new one or a service plan. Thanks, Devin.

it sounds to me that either the battery is dead on your iphone or one of the battery wires may have come lose from the motherboard,

The only way to check these things is to open the iphone up. Have a tech open it and first check if it has been water damaged. If it has been water damages, check the voltage on the battery. With a volt meter you should get 4.20 volts or higher.

If the battery is very low while the iphone is open, plug the charge in and test the voltage with it plugged in. It should vary from without the charger in. If not difference it could be the charging port, chean with a brush, if there is green electrolysis in the charging port you can use vinegar to clean it, if your going to clean with a liquid, it's best to remover the motherboard so the charging port is not hot. The symptoms your iphone exhibits could be many different things. check what you can and have a tech test the rest.
