So your iTunes gets stuck on step 2 when you try to sync your iPhone or iPad?
Here’s what you do about it. This has been proven to work. If it helps you let us know in the comments below
How to get the sync going
Look at the picture below. That is the task manager. To get there hold down Control, Alt, and Delete at the same time. After you do this something will pop up giving you several options. Pick Task Manager. Then click on processes and look for MobileBackup (see red arrow below). Click once on that and then click End Task at the bottom right. If a popup appears asking if your sure then hit yes. Now go back to iTunes. It should now be syncing.
*Note by doing this you are skipping the backup step so your phone will not be backed up**
If that doesn’t work
Set iTunes to sync your iOS device over Wi-Fi
Open iTunes. Make sure that you have the latest version.
Use the USB cable that came with your iOS device to connect it to your computer.
In iTunes, find and then click your iOS device.
On the Summary tab, select “Sync with this [device] over Wi-Fi.”
Click Apply, then disconnect the USB cable.
Choose the items that you want to sync, then click sync.
When the computer and the iOS device are on the same Wi-Fi network, the iOS device appears in iTunes. The iOS device syncs automatically whenever it charges and iTunes is open on the computer. Learn more about what you can sync and how to sync specific items.
