The Sony Xperia E1 dual was released in 2014 and ran Android 4.3 out of the box. Although it is upgradable to Android 4.4.2 KitKat, that is as recent a version of Android that Google supports for this smartphone. That means if you use it long enough, you will likely come across some apps that freeze or are prone to lockups. This is because most apps are developed with the latest versions of Android in mind and aren’t capable of running on older versions of the Android OS as well. Thankfully Android does come with the option to take a hard reset, which is what you want to do when you witness the Sony D2105 locking up.

How to Hard Reset/Factory Reset Sony D2105 Smartphones

You can apply the hard reset/factory reset from the Sony D2105 smartphone’s bootloader menu. Here is how you can do that:

1. Hold down the Power button to turn off the Sony D2105 smartphone.

2. Restart the Sony D2105 smartphone holding the Power + Volume Up buttons simultaneously for around three seconds.

3. Let go of the two buttons you were holding when you see the Android Recovery menu.

4. Use the Volume buttons to scroll through the list and select Wipe data/factory reset, and then confirm your selection by pressing the Power button.

5. When it asks if you want to Wipe all user data? This CANNOT BE UNDONE!, use the Volume buttons to select Yes, and then press the Power button to confirm the command.

6. Wait until you get a message at the bottom of the display that says something akin to … Set Factory Reset done … Data wipe complete.

7. When you get back to the Android Recovery screen again, use the Volume buttons to scroll through the list and select Reboot system now, and confirm your selection by pressing the Power button.

8. Once the operating system restarts, you can start using the device again if you like.

That’s all.
