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.
What is a Hard Reset?
A hard reset, also known as a factory or master reset, is a software restore for an electronic device, bringing it back to its original and default state, as though you had just opened it out of its box and begun using the operating system for the first time. That means you can expect to find all your data and settings erased, and you will need to take the necessary steps to start using the device once again, which includes setting up an account if your operating system requires one.
Some operating systems such as Android require you to sign in to your Google account after a hard reset, so make sure you have your Google email address and password handy if your smartphone runs on Android.
The way you take a hard reset will vary between devices. You can contact your device manufacturer for the procedure or search for the words “hard reset,” followed by the name of your device.
What is the Difference Between a Hard Reset and Soft Reset?
Although generally reliable, the operating system on your smartphone is prone to freezing now and then. It could be because you do not have enough RAM, and when you try browsing too fast, it is not able to cope, or it could be any number of other reasons. To solve these types of general issues, you will need to perform either a soft or hard reset.
A soft reset. You want to use the soft reset option on your smartphone to solve any number of smaller problems that were unable to be solved with a standard restart of the smartphone. Try a soft reset to fix common mobile-related problems before you try a hard reset.
A hard reset. A hard reset is your last resort for any ongoing problems faced after applying a soft reset. The hard reset has the upside of always being able to solve whatever challenges you face; however, also understand that by hard resetting, you are restoring the device to all its original factory settings. That means you will wipe all data, settings, applications, and passwords from the smartphone’s internal memory.
Why Take a Hard Reset?
Sometimes it can be hard to determine whether you need to take a hard reset or not in order to rectify a problem. The easiest way of knowing whether or not you need to take a hard reset is by trying the soft reset first.
Taking hard resets is not always about solving issues, though. Also common is to take a hard reset to purposefully wipe all data before you sell or hand over the smartphone to someone else. That way, you will keep your privacy, and they will never know what data you had on the smartphone before it leaves your possession.
You should take a hard reset if you want to achieve any of these things:
- Factory reset the device
- Wipe all data on the device
- Bypass the screen lock on the device
- Restore the Android factory defaults on the device
The following tutorial demonstrates how to hard reset the Sony D2105 smartphone so you can restore it to its factory defaults.
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.
What is the Difference Between a Factory Reset and a Hard Reset?
There is no difference between a factory reset and a hard reset—the two terms are interchangeable. Sometimes people suggest that a factory reset is the equivalent of a hard reset and a hard reset is the equivalent of a software reset, but those sentiments are untrue. A soft reset is not the same as a standard reboot or restart of an operating system; what often sets them apart is the soft reset requires you to hold in the Power button, usually for around ten seconds on most devices, whereas the standard restart happens straight away from the Power menu.
Taking the Hard Reset Did Not Solve My Problem, What Next?
If you still are having problems with your operating system—or its software—after trying the hard reset, you can try reinstalling the stock firmware. If you do not want to try flashing firmware files, we recommend getting in touch with your manufacturer, either from their official website or one of their official social media pages for advice on what to do next. It might be that they ask you to send the device away for repair instead.
Note: Applying a hard reset to the smartphone or tablet will not void the manufacturer’s warranty, but manually reinstalling the firmware might.
What is Factory Reset Protection (FRP)?
Some smartphones come with a feature, available on Android since version 5.0 (Lollipop), called Factory Reset Protection. FRP is designed to deter smartphone theft by making it harder for the unlawful possessor of the smartphone to gain access to it. It also means your data is kept safe if your smartphone is lost or stolen. FRP is not flawless—there can be ways around it—so Android may need to use better methods in the future for device owners to rest assured their data is safe. Still, for now, it is the standard adopted by many Android smartphone manufacturers.
