Back up before a master reset: Android

A master reset is sometimes called a factory data reset or reset for short.

 

A master reset restores the phone to its original settings, as if it is new again. This deletes the information stored on the device. Information stored on the memory card or synchronized to a Google account is usually saved, though some devices erase the memory card. Follow these steps below to back up any data that you may lose.

 

 

 

 

Turn off Automatic Backup

Android can automatically back up your settings. However, if there are problems with your settings and you automatically back them up, the problems will return after a reset. T-Mobile recommends that you turn off this feature.

 

  1. From the Home screen, press the Menu key.
  2. Tap Settings.
  3. Tap Privacy.
  4. Tap the Back up my settings check box to clear it.
  5. Tap OK.
  6. Make sure there is no check mark in the Back up my settings check box.

 

 

View & Sync Accounts / Calendars / Emails

  1. From the Home screen, press the Menu key.
  2. Tap Settings.
  3. Tap Accounts & sync.
  4. Look for a Google account (as well as any other email addresses):
    • Write down the account names, and remember your passwords. You will need them to log in after the reset.
    • If you do not know your password, go to https://www.google.com/accounts/recovery from a computer.
  5. Touch Sync all button to back up your synchronized data.
  6. After the sync instructions above, you can check calendars are backed up:

    1. From a computer, open your calendar on www.google.com/calendar or Microsoft Outlook.
    2. Make sure all your calendar items appear.
  7. After the reset, log in to the accounts and sync the phone to restore contacts and other info.

 

 

Contacts

Your contacts may be backed up to Google, your SD card, or other sources. See your device information > How-to guides > Settings > Backup & restore.

 

 

Messages

Email

Email is typically stored on the servers of the email provider (not on the device), so you do not need to back it up.

 

Text messages (SMS) & picture messages (MMS)

Android does not back up your text messages (SMS) and picture messages (MMS).


Some devices have a backup feature added, which you can see in your device information > How-to guides > Settings > Backup & restore. There are also non-T-Mobile applications in the Play Store that can back up your messages. T-Mobile does not support these applications, but you can contact the developer for help.

 

T-Mobile recommends that you do NOT restore the messages after the reset. Having many messages can cause phone problems.

 

 

Apps

Paid applications are already saved to your Google account. If the app stored data (save games, high scores, memos, preferences, etc.) on:
  • The memory card, then the data will be saved.
  • The phone memory, then the data may be lost.

 

If your phone has options to back up app data, you can see your device information > How-to guides > Settings > Backup & restore. There are non-T-Mobile applications on the Play Store that can back up your app data. T-Mobile does not support these applications, but you can contact the developer for help.

 

 

Media

Android devices may save your media (pictures, photos, videos, music) on the SD card. If it is stored on the internal storage, you can move it to the SD card or a computer. See your device information > How-to guides > Settings > Backup & restore.

 

 

SD card

Some Android devices give you the option to erase or "format" the SD card. In most cases, this is not necessary.

 

You may erase the SD card if you think that an app has stored corrupted data on it. However, because it contains most of your phone data, follow steps below to back up the files first.

 

  1. Connect your phone to a computer with a USB cable.
  2. When the computer shows a Removable disk popup, select Open folder to view files.
    Note: If the computer does not show the phone as a drive, then pull down the Notification bar and change the USB connection type to Disk drive.
  3. Copy all the files from your SD card to a folder on your computer.
  4. Perform a master reset or format the SD card. See your device information > How-to guides.
  5. After the reset, you can do the same thing to move them back. Do not copy any files back to the SD card if you suspect they are corrupted, or the problems will return.
