Hello, I recently got my hands on a faulty iPhone 4, the problem is, it doesn't turn on, when you plug it into the wall charger, the apple logo comes up for about 10-15 seconds, and turns off, then does that again, and does continuosly does that. When I plug it into a computer, it shows no sign of life, if I follow the instructions to put it into DFU mode, I see no apple logo, but it does succesfully get into DFU mode, and is recognized by iTunes, but when I try to restore, I always get error 1601, in pwned dfu mode or not. I think it is the battery because when it is on the apple logo on the wall charger, as soon as I take it out, it turns off. I have tried the power button + home button etc, so I rang apple and they are arranging to allow me to send it to them, but I realised that the moisture sensor in the headphone jack is half red, even though it has never come into contact with water at all, so what can I do?
