What is a bootloader and why you might want to unlock it
A bootloader is a piece of software that runs when you power on your Android device. It is responsible for loading the operating system and other essential components into the memory. The bootloader also checks the integrity and authenticity of the system and boot images, and prevents unauthorized modifications.
Unlocking the bootloader means allowing the device to accept custom images that are not signed by the manufacturer or the carrier. This can give you more control over your device, such as installing custom ROMs, kernels, mods, or rooting. However, unlocking the bootloader also comes with some risks, such as voiding your warranty, losing your data, exposing your device to security threats, or bricking your device.
Before you decide to unlock your bootloader, you should make sure that you have a backup of your data, a compatible device, a USB cable, a computer, and an internet connection. You should also be aware that unlocking your bootloader may require a code from the manufacturer or the carrier, depending on your device model and brand.
How to download unlock bootloader apk
An unlock bootloader apk is an application that can help you unlock your bootloader without using a computer or fastboot. It is usually designed for specific devices or brands, and may not work for all devices. You can find some unlock bootloader apks on websites like XDA Developers, APKPure, or APKMirror. However, you should be careful when downloading and installing these apks, as they may contain malware or viruses.
To install and use an unlock bootloader apk, you need to enable unknown sources in your device settings. This will allow you to install apps from sources other than the Google Play Store. Then, you need to download the apk file from a trusted source and open it on your device. Follow the instructions on the screen to grant permissions and complete the installation. After that, you can launch the app and follow the steps to unlock your bootloader.
The limitations of using an unlock bootloader apk are that it may not work for all devices or Android versions, it may not support locking the bootloader again, and it may not be updated regularly. If you want a more reliable and universal method of unlocking your bootloader, you should consider using fastboot.
How to unlock the bootloader using fastboot
Fastboot is a tool that allows you to communicate with your device in bootloader mode. You can use fastboot to flash images, erase partitions, or execute commands on your device. To use fastboot, you need to install it on your computer along with Android tools such as ADB (Android Debug Bridge).
To install fastboot on Windows, you can download the latest Android tools ZIP file from Google and extract it into a folder. Then, open a command prompt window in that folder by right-clicking on it and selecting “Open command window here”. To install fastboot on Ubuntu/Debian Linux, you can open a terminal window and run this command: sudo apt install android-tools-adb android-tools-fastboot
To enable OEM unlocking and USB debugging on your device, you need to go to Settings > About phone > tap Build number seven times. This will enable developer options in your settings. Then, go back to System > Developer options > toggle on OEM unlocking > toggle on USB debugging.
To connect your device to your computer and run fastboot commands, you need to plug your device into your computer with a USB cable and reboot it into bootloader mode. You can do this by holding the power and volume down buttons simultaneously, or by using this ADB command: adb reboot bootloader. Then, you can open a command prompt or terminal window on your computer and run this fastboot command: fastboot devices. This will show you the serial number of your device and confirm that it is connected. Next, you can run this fastboot command: fastboot flashing unlock. This will prompt you to confirm the unlocking process on your device screen. Use the volume buttons to select yes and the power button to confirm. This will unlock your bootloader and erase your data. Finally, you can reboot your device by running this fastboot command: fastboot reboot.
How to lock the bootloader after unlocking it
You might want to lock your bootloader again after unlocking it for various reasons, such as restoring your warranty, improving your security, or fixing some issues. However, locking your bootloader will also prevent you from installing custom images or rooting your device.
To lock your bootloader using fastboot, you need to follow the same steps as unlocking it, but with a different command. First, connect your device to your computer and reboot it into bootloader mode. Then, open a command prompt or terminal window on your computer and run this fastboot command: fastboot flashing lock. This will prompt you to confirm the locking process on your device screen. Use the volume buttons to select yes and the power button to confirm. This will lock your bootloader and erase your data. Finally, reboot your device by running this fastboot command: fastboot reboot.
The consequences of locking your bootloader are that you will lose all your data, you will not be able to install custom images or root your device, and you may encounter some errors or problems if you have modified your system before locking it. Therefore, you should only lock your bootloader if you are sure that you want to do it and that you have a backup of your data.
