How do I reset the phone to factory settings?

Jolla Care -

 

Please note

Device reset to factory settings means the following:

  • All user data, settings and accounts are deleted from the device and are irretrievable after this operation (however, data on the memory card remains intact) 
  • All applications installed by the user are removed
  • The operating system is reverted to the version the device had when leaving the factory or that was installed later by "flashing". You will need to update the phone to the latest OS version which implies installing a chain of Stop Releases. In the worst cases, this may take several hours.
  • In the case of Xperia devices, we recommend re-installing (by "flashing") Sailfish OS to the device, instead of resetting it. This is easier and saves you from many extra steps. While the reset reverts your phone to one of the earlier OS versions, you will get the latest OS release directly by flashing it to the phone. See our comparison of device reset to re-installation. Our instructions for flashing are in this support article.

1 Preparation

It is recommended to take a backup of the data in your device and copy it to an SD card before running the reset (if possible). Once done then proceed to the reset.

Whether unsure if the device reset will erase data you will need once it's gone, please make a list for yourself of all files or other information on your device that is important to you, and use our backup article as a resource to learn what information can be saved and how.

 



2 Resetting the device

1. Connect a battery charger to the device.

2. Go to menu Settings > System > 'Reset device'.
NOTE: This feature is missing from Xperia 10 II and Xperia 10 III devices. Consider re-installing ("flashing") the latest Sailfish OS release to the device. This article explains how to do it.

3. Tap 'Clear device'.

4. Read the disclaimer, and tap 'Accept' if you are ready to proceed.

5. If you have the device lock enabled, it will prompt for the security code.

6. The reset starts now.

The reset typically takes 1-2 minutes. It ends when the device is turned off, i.e. the display is and remains black. No LEDs are lit.

You can then restart the device by using the Power key on the side of your device.

 



3 First actions after the reset

Especially in the case where the reset has reverted your device to one of the early SailfishOS versions (1.x.y.z) it is recommended to run the first start-up in the way described below. Updates from Sailfish generations 2, 3 and 4 work reliably; also the first start-up described in chapter 3.1 below is simpler and does not require any precautions.

The main idea below is to update Sailfish OS to its latest version first, and only then install the apps and accounts.

These guidelines are to avoid the situation where you upgrade the OS while the device keeps installing a set of apps in the background. This has sometimes caused serious problems.

 

3.1. Run the startup actions, including

The steps of the startup below are different between Sailfish 1 versus Sailfish 2, 3 & 4. Check the current version at "Settings > System > About product" (or Product Info) if needed. The startup of Sailfish 1 is sensitive to errors, so please follow the steps of chapter b) precisely.

 

a) If your current Sailfish OS version is from Sailfish generation 2, 3 or 4 generation

- select language
- accept the SailfishOS terms of use
- check date and time; set correct or else updates would fail
- sign in to your Jolla account which requires selecting the Internet connection (WLAN or mobile data); instead of signing in you can also register a new Jolla account (this requires a different email address, though).  If signing in should keep failing then skip this step and sign in once you have completed the startup actions. You will need to sign in to get the SailfishOS update in chapter 3.2 below.
- "Get your apps"
- Skip the Tutorial by tapping all four corners of the display in a clockwise direction - start from the top left.

Let your phone install the apps before you proceed from here.

 

b) If your current Sailfish OS version is one from Sailfish 1 generation

- select language
- accept the SailfishOS terms of use
- enter PIN code (if applicable)
- choose your favourite colour
- check date and time; set correct or else updates would fail
- skip "My Info" as there is no use for this information for now
- sign in to your Jolla account which requires selecting the Internet connection (WLAN or mobile data); instead of signing in you can also register a new Jolla account (this requires a different email address, though).  If signing in should keep failing then skip this step and sign in once you have completed the startup actions. You will need to sign in to get the Sailfish OS update in chapter 2 below.
- STOP here for 15 minutes if you want to be foolproof and avoid some update issues - in the meanwhile the device will update the pointers to application repositories so that they match your next OS version (*)
- SKIP signing in/up to other accounts
- SKIP "Get your content"
- SKIP "Get your apps" (we will do this later)
- SKIP the Tutorial by tapping all four corners of the display in a clockwise direction - start from the top left.

 

3.2. Get the SailfishOS update

The device has probably presented a notification about SailfishOS update by now. Please download and install it now:

- visit menu page "Settings > System > Sailfish OS updates"
- follow the on-screen instructions
- detailed instructions on installing a Sailfish OS update are given on this page - please read it!

Please note that it is not necessarily possible to update the OS to the latest version directly but in one or more steps. There are so-called Stop Releases in the update path. All of them must be traversed. Sailfish OS should automatically suggest the next stop release for you in "Settings > System > Sailfish OS updates".  Download and install it.

If you start the update process from one of the Sailfish 1 versions, please read chapter 4 "Updating from early Sailfish OS versions" in this support article.

 

 

Should you need help with the commands above, please file a request at Jolla Service & Support.

 

3.3. Install your primary applications

Install your most-used applications from Jolla Store (install more apps later)

 

3.4. Restore your data from the SD card

Restore the backup from the SD card.  Follow the instructions here.

 

3.5. Check your accounts

Check your accounts (e.g. Google, Exchange, Facebook) on the menu page Settings > Accounts. Backup should have restored the account settings; however, it is best to check all accounts and sign in again if necessary.

 

3.6. Check your settings

All settings are in their default values after the factory reset. Some of them may not have your favourite values. Check at least the following:

  • Settings > Look and feel > Gestures: "Quick app closing" and "Quick Events access"
  • Settings > Look and feel > Events view: "Setting shortcuts" and "Select actions"
  • Settings > Look and feel > Display: "Sleep after"
  • Settings > Location: "Location"
  • Settings > Apps > Phone: "Quick call" (read this)
  • Settings > Apps > People: Check "Show" and "Sort" options
  • Settings > Apps > Camera: Select "Memory card" for "Storage" if card is available.
