What is bootloader and why unlock it?
A bootloader is a piece of software that runs when you power on your device. It checks and loads the operating system and other essential components into the memory. The bootloader also acts as a security mechanism that prevents unauthorized or malicious software from running on your device.
By default, most Android devices have a locked bootloader, which means that they only accept official software signed by the manufacturer or the carrier. This ensures that your device runs smoothly and securely, and that you receive regular updates and support from the manufacturer. However, this also limits your ability to modify or replace the software on your device.
By unlocking the bootloader, you can bypass this restriction and flash custom software on your device. This can give you more control over your device features, performance, battery life, and appearance. You can also install custom ROMs that offer different versions of Android or additional functionality. You can also root your device, which gives you superuser access and allows you to tweak system settings, remove bloatware, install apps that require root permissions, and more.
Benefits and risks of unlocking bootloader
As mentioned above, unlocking the bootloader can offer some benefits for advanced users who want to customize their devices. Some of these benefits are:
You can flash custom ROMs that may offer better performance, stability, battery life, or features than the stock ROM.
You can flash custom kernels that may improve the speed, responsiveness, or efficiency of your device.
You can flash mods or tweaks that may enhance the functionality or appearance of your device.
You can root your device and gain superuser access to modify system settings, remove bloatware, install root apps, and more.
However, unlocking the bootloader also comes with some risks and drawbacks that you should be aware of before proceeding. Some of these risks are:
You may void the warranty of your device and/or any warranty from your operator. See your devices warranty statement for details.
You may lose some functionality or features that depend on DRM security keys or official software. For example, some camera functions or pre-loaded content may not work properly after unlocking the bootloader.
You may damage your device permanently if you flash incompatible or faulty software. You may also experience bugs, crashes, or instability issues with custom software.
You may lose all your data and settings when unlocking the bootloader, as it will trigger a factory reset. You should backup your data before proceeding.
You may not receive any official software updates from Sony if you unlock the bootloader. Requirements for unlocking bootloader

Once you have all the requirements ready, you can proceed with the steps below to unlock the bootloader on your Sony Xperia device.
Step 1: Check if your device is supported
The first step is to check if your device is supported for bootloader unlocking. Not all Sony Xperia devices can be unlocked, and some devices may have a locked bootloader that cannot be unlocked by the user. To check if your device is supported, you need to find your device model and IMEI number, and then check the unlock status of your device.
How to find your device model and IMEI number
Your device model and IMEI number are unique identifiers that are required for getting the unlock key from Sony. To find them, you can follow these steps:
On your device, go to Settings > About phone > Model number. Note down the model number of your device.
On your device, go to Settings > About phone > Status > IMEI information. Note down the IMEI number of your device.
How to check the unlock status of your device
To check if your device has a locked or unlocked bootloader, you can follow these steps:
On your device, open the dialer app and enter *#*#7378423#*#* to access the service menu.
On the service menu, tap Service info > Configuration > Rooting Status.
Look for the line that says Bootloader unlock allowed. If it says Yes, then your device can be unlocked. If it says No, then your device cannot be unlocked by the user.
If your device is supported for bootloader unlocking, you can proceed to the next step. If not, then you will not be able to unlock the bootloader on your Sony Xperia device.
Step 2: Install the device drivers and platform tools
The next step is to install the necessary software on your computer that will allow you to communicate with your device and execute commands. You need to install the Sony USB drivers for your device, and the Android SDK platform tools that include the Fastboot and ADB tools.
How to download and install the Sony USB drivers
The Sony USB drivers are required for connecting your device to your computer and recognizing it as a USB device. To download and install them, you can follow these steps:
Go to the Sony website and select your device model from the drop-down menu.
Click on Download USB driver and save the file on your computer.
Extract the zip file and run the setup.exe file to install the driver.
Follow the instructions on the screen to complete the installation.
How to download and install the Android SDK platform tools
The Android SDK platform tools are required for using the Fastboot and ADB tools that will allow you to execute commands on your device. To download and install them, you can follow these steps:
