"Won't turn on or charge" için yanıtOK, this is not an answer, but is what is happening to my ipod. Classic 120 GB. I replaced the battery, as the original one was finally hosed. However, this particular problem raised its ugly head after I synched it to itunes, and upgraded it. I am not sure which version that did it in, but as soon as I upgraded it, I could not get it to turn on, unless it was attached to power. Then I had to hold the center button and the menu button to get it to turn on. However, that was intermittent, because sometimes it worked, and sometimes not. Anyone have a solution for this? Is there a way to go back to the factory version. Like os 1.0?
