Avoid the point of no return – back up your phone and your stuff onto your computer.
Your settings, documents, photos, music, and videos are automatically backed up during the software update, when you update your phone using the primary computer (the computer you first connected your phone to with a USB cable). If you use a different computer to update your phone software, no backup is created. You can change your primary computer in the Zune settings.
If you don't yet have Zune, go to http://www.zune.net/ to download and install the latest version on your computer. If you're using an Apple Mac, download Windows Phone 7 Connector for Mac from the Mac App Store.
- Connect your phone to your computer with a USB cable.
- Open Zune.
- Wait while Zune checks for available updates, and follow
the instructions shown on your computer.
Your downloaded apps may not be included in the backup, but you can re-download them from Marketplace, free of charge. Data transmission costs may apply. For more info, contact your network service provider.
You can also sync your phone to your computer with Zune or Windows Phone 7 Connector for Mac without updating your phone software. Syncing does not back up your system settings or your apps. You can also set your phone to sync your contacts through Outlook, so you can restore them to your phone from your computer.
Restore a backup to your phone
- Connect your phone to your primary computer with a USB cable, and use Zune to restore your backed up content and the earlier version of your phone software.
