Hold switch does not work
The hold switch of my ipod classic touch does not work and is locked how can i unlock?
iPod classic
If none of the 5 R's are able to resolve the issue, it's likely a hardware issue, meaning you'll need to have the iPod serviced/replaced either by Apple or a third party service.
