Is it a bad dock connector?
Again I'm back to the iPhone 3GS. I'm a hobbyist with tech, and I REALLY want to get this phone working. Just gonna jump right in. The phone almost never will charge, if I try to restore it 90% of the time it fails, and often it's completely dead except when I plug it in and press my ear to the phone there is a repetitive discharge-like tick sound and sometimes some weird long or short beeeep or beaaeaeap sounds. Hmm... I have successfully restored it several times, so it isn't software/firmware. Now... Dock connector or logic board? or bad connection?
