I followed what another user had suggested and didn't remove the logic board - it worked well and I managed to do it easily enough. However, when trying to remove the solder and cable from the battery terminals (it was really tricky) I think I may have pulled the pad off. I put my iPod back together anyway but now it won't boot, show up in iTunes when it's plugged in or (in fact) do anything. Could the possible loss of the middle terminal be the root of these problems?
