Hello, I got a new used iPod classic 5.5 and I cannot reset it by pressing the select and menu buttons at the same time. Both buttons work separately, but pressing them at the same time never triggers a reset even if I hold them for a pretty long time. I also tried with flipping the hold switch from on the off and then pressing those buttons and it still did not work. Any idea why this might be the case? The seller I bought from said they put in a new clickwheel, could that be part of the problem?
