Preparing for a software update

Preparing for a software update

To make sure a software update can be carried out smoothly and without interruptions, prepare your phone and computer first for the update. Here are some tips on what you need to check and prepare.
  • If your battery level is low, give your phone a quick charge before starting the update.
  • Check how much free space you have on your phone and make some room for the update. To find out how to check the available storage, see Checking phone info and storage.

    If necessary, remove a few unwanted apps. Refer to Uninstalling an app to see how it's done.

    Or delete large files (such as photos, videos, or music) from your phone.

  • Make sure you have Zune installed on your computer. You'll need it to download the software update. For details, see Installing and setting up the Zune software.
  • Free up space on your computer.

    You'll need some room to download the software update, to save a backup of your existing phone software and settings, and possibly to sync media files from your phone to your computer.

  • Make sure your computer has a reliable Internet connection.

    In some cases, you might need to switch from a Wi-Fi connection to a wired connection. Or you might need to adjust your computer's firewall or proxy settings.

  • Make sure your phone is set with the correct date and time. This determines which new updates you'll need. For details, see Correcting the date and time.
