“Why won’t my iPhone sync to iTunes? What happened? What I can do to sync data between iPhone and iTunes?” I believe that many iOS device users may have been faced with or are facing the same iTunes problem after updating to the latest iTunes version. Typically iTunes will sync with an iOS device without incident, but sometimes things go away, and iTunes just won’t sync at all. If you find yourself in that frustrating situation, here is what you can do to fix it and get the iPhone, iPod, or iPad syncing with iTunes on PC again.

Part 1. How to Fix When iPhone Won’t Sync with iTunes

Before trying to fix the iTunes error with some methods, you need to be sure you have the newest version of iTunes on the computer. Sometimes just updating to the newest version of iTunes is enough to resolve all syncing problems, particularly if the desktop software hasn’t been updated in a while. You can always download the newest version of iTunes directly from Apple. After updating to the newest version of iTunes, if you find that your iPhone still won’t sync with iTunes, you can follow the tips below to fix the error.

1. You can simply quit out of iTunes, then relaunch the app, and try syncing again. Sometimes this is enough to get your iTunes working again.

2. If syncing fails, the Sync button is greyed out and not available at all, or if you try to sync and nothing transfers over to the iPhone, iPod, or iPad, you may simply need to authorize the computer with iTunes.

3. You can also try restarting your phone by holding down the home button and power button.

4. Sometimes just restarting a Mac or PC is enough to resolve the problem and get things syncing again.

5. Typically use Wi-Fi Syncing? Try using a USB cable instead. Usually use a USB cable? Try using Wi-Fi syncing instead to see if that works.

6. 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.

7. Sometimes USB ports go bad, and though it’s pretty rare it’s very easy to rule out. All you need to do is switch the USB cable from one port to another and see if it works.

8. Reset and restore the iPhone. This should be your last option. You will lose all the data on your device. You will be resetting your phone to factory settings and start as if its a new phone. Only advantage is that you have iCloud backup.

Part 2. How to Backup Files When You cannot Sync iPhone with iTunes

As you cannot sync iPhone with iTunes, you won’t be able to use iTunes to update your iPhone backup. But iCloud will provide you much help. If you have connected to Wi-Fi, you can tap Settings > iCloud > Storage and Backup > Back up Now to create an iCloud backup.

Step 1. Click Settings, then tap on iCloud.
Step 2. Tap Storage & Backup
Step 3. Tap Back Up Now.

You can also backup iPhone with iCloud automatically. On your iOS 8 device and above: Go to Settings > iCloud > Backup, then turn on iCloud Backup. On your iOS 7 device and below: Go to Settings > iCloud > Storage & Backup, then turn on iCloud Backup. iCloud will attempt to backup your data every 24 hours or so, as long as your iPhone is connected to Wi-Fi and plugged into charge, and your screen is locked. But the media files won’t be included in an iCloud backup, so you will need an iPhone transfer program to back up the media files from iPhone to computer you want to set up iPhone as a new one.
