Restarting an i Phone, i Pad, or i Pod touch is just a matter of Holding down the Power button and Home button simultaneously until the device restarts.
Technically, that approach is called a Hard Reboot because it forcibly restarts the i OS device, but in situations where things are acting up, crashing, or just not behaving properly, it’s usually more effective to force reboot than to use the standard power-off approach.
i OS is obviously going in the direction of not needing i Tunes at all, but in the meantime you still need to sync an i Phone, i Pad, or i Pod touch to copy over music libraries, videos, media, perform local backups, apps, and more.
Typically i Tunes will sync with an i OS device without incident, but sometimes things go awry, and i Tunes just won’t sync at all.
Do note this guide is aimed at resolving actual syncing problems (ie: the transfer of data between i Tunes and the computer), not at problems with detecting the devices themselves.
We’re going to cover a variety of troubleshooting tricks to fix the syncing problem here, try each in descending order until the problem is resolved.The seventh-generation i Pod nano was announced on September 12, 2012.It introduced Bluetooth 4.0 support for compatible wireless headsets and heart-rate monitors.Once the i OS device has been restarted, try syncing again. Try using Wi-Fi syncing instead to see if that works.
Yes restarting the computer can be annoying, but sometimes just restarting a Mac or PC is enough to resolve the problem and get things syncing again. USB syncing is usually the most reliable method, and it’s not terribly uncommon for wi-fi sync to be a bit more picky.
This is particularly true if the issue has to do with a malfunctioning daemon like the i Tunes Helper Service or the Apple Mobile Device Helper process. If you find wireless sync to suddenly stop working, you typically just have to toggle the feature on and off again to get it functioning again, which must be done by connecting the i Phone, i Pad, or i Pod to the computer by USB and rechecking the “Sync over Wi-Fi” option again under the Summary tab.
