Logic board heats up as soon as it's put in
Hi there. I bought an iPhone 3G 8g and at first it wouldn't turn on at all. I have since worked out that the battery was completely dead when I got it. Put it into another iphone3g 8g and charged it then put it back into original phone but before I even got to putting the screen back in the logic board was so hot I had to take it back out with tools. Just sitting the logic board into place no screws no conectors attached it gets very hot closest to connector 5 and 6. Does this mean all is lost?
