How do I get my Windows Phone 8.1 device ready to install the upgrade?

If the update to Windows 10 Mobile is available for your Windows Phone 8.1 device, here are some things to keep in mind before you start:

  • Plug your phone into a charger to make sure it doesn't run out of battery during the upgrade.

  • Connect your phone to a Wi‑Fi network. Because of the size of the update, a Wi‑Fi connection is required for download and installation.

  • It’s a good idea to back up your settings, apps, photos, and text messages to the cloud before installing the update. To set up backups, on Start Start icon, swipe over all to the All apps list, and then select Settings Settings app icon > Backup, and then follow the instructions.
  • Free up enough storage space to download and install the update. You can use the Upgrade Advisor app and it will recommend files, such as videos or photos, that you can move to OneDrive or an SD card, if you have one installed. You can also connect your phone to a PC and move your files there. After the upgrade, you can move files back to your phone if there's enough space.

    Note

    • If you remove apps from your phone, you can reinstall them from the Store after the upgrade if there's enough space. Deleting an app will erase app data, such as saved progress in a game.

How do I install the upgrade on my Windows Phone 8.1 device?

When the update to Windows 10 Mobile becomes available, on Start Start icon, swipe over all to the All apps list, and then select Settings Settings app icon > Phone update, and then install the update. You can choose to install the update immediately or postpone the update for a more convenient time.

Notes

  • To check for updates, on Start Start icon, swipe over all to the All apps list, and then select Settings Settings app icon > Phone update > Check for updates. Make sure the check boxes for Tell me when updates are available for my phone and Automatically download updates if my data settings allow it are selected.
  • On Windows Phone 8.1 devices that are running OS version 8.10.14219.341 or higher, you can schedule to install downloaded software updates later. On Start Start icon, swipe over all to the All apps list, and then select Settings Settings app icon > Phone update > Preferred install time.

Depending on the model of your Windows Phone 8.1 device and the number of apps installed, the upgrade might take an hour or more to complete. You won’t be able to use your phone during the installation and it will restart a few times.

After the upgrade to Windows 10 Mobile is done, some additional time might be necessary to finish migrating data and apps. If some app tiles don’t appear active or you’re not able to open them, keep your phone plugged in a charger and connected to Wi‑Fi, and wait for these apps to finish updating. If an app tile is missing from Start, check the App list for the app and pin it to Start, or go to the Store and see if a new version of the app is available.

Additional app updates might need to be installed from the Store for some features to work on your phone. To check for app updates in Windows 10 Mobile, on Start Start icon, swipe over all to the All apps list, and then select Store Settings app icon > Menu > Downloads and updates > Check for updates.
Make sure to download and install any updates that are available for your upgraded phone. On Start Start icon, swipe over all to the All apps list, and then select Settings Settings app icon > Update & security > Phone update > Check for updates.

How do I keep my Windows 10 Mobile device up to date?

  1. On Start Start icon, swipe over all to the All apps list, and then select Settings Settings app icon > Update & security > Phone update.
  2. Select Check for updates to see if any updates are available. To change update settings, select Advanced options.

Why won't my phone upgrade to Windows 10 Mobile?

The best way to know if the upgrade to Windows 10 Mobile is available for your phone is to install and run the Upgrade Advisor app.

If the upgrade is available for your phone and you used the Upgrade Advisor app to enable the upgrade, but you're having problems downloading or installing it, wait a few minutes and then try again later. When installing the update, it's a good idea to make sure your battery is fully charged (or plug in your phone), use a Wi‑Fi connection instead of a cellular data connection, and free up space by removing files you no longer need.

For more info about error codes you might see during updates, see Get help with Windows 10 Mobile update errors.

Can I go back to my previous version of Windows Phone?

If you upgraded your Windows Phone 8.1 device to Windows 10 Mobile, you can use the Windows Device Recovery Tool to rollback to a previous version. For more info about this tool, see Windows Device Recovery Tool: FAQ.
