So I followed this guide (and a bunch of others) for tearing down and replacing parts of my iPod. I finished everything, and I'm sure I got the right parts, but now it won't turn on. It says "The iPod software update server could not be contacted. The server does not support this version of iTunes." While I understand that iFixIt is not an Apple company, I feel like my iPod should be fixed? I'm pretty sure I did everything correctly.... Why won't it turn on?

Since you guys seem to rarely have any of the parts in stock, is this headphone jack and switch the right kind? https://www.amazon.com/gp/product/B00QSI...
