If you’ve got there, you’ve surely wondered: What is the bootloader? Sure, you have tried to install a new unofficial Custom ROM on your Android device and found that for this you need to unlock the bootloader. In this tutorial you will find an explanation of what is the bootloader of an Android mobile, a topic that is currently current.
You will find the term also called bootloader, and we can say that it is a code or set of simple programs that are loaded before the operating system, adding to each other to prepare everything that it needs to function, so that the last one runs the full operating system. The bootloader also exists in PC operating systems, as well as in laptops and other devices.
Being free software, Android is susceptible to modifications, and this is where the great importance of the bootloader on Android devices lies. If we install a new version on our device, it will have to pass the bootloader filter to be able or unable to start.

CHow the Bootloader works. The bootloader, or boot loader, checks that all hardware is working properly before allowing the operating system kernel to start. In the case of Android, the Bootloader code is different for each of the computers, different for each version of the operating system, also different for each company.
The bootloader is a program that activates the operating system in the correct way, each time and then when the device is turned on. The bootloader determines when to run the Android operating system on the device or when to enter the device’s recovery mode, which is a separate execution environment on a separate partition from the AndroidOS operating system and is found on all Android devices.
Bootloader crashed: what to do? The bootloader on devices with Android operating system is provided directly by the device manufacturer and is located in a different section of the device’s internal memory, a partition that cannot be modified by the user. The user, wishing to modify the device, will find a major obstacle, bootloader.

What does this mean? A bootloader in the locked state will only load that operating system authorized by a digital signature. Android device manufacturers decide to block it to block and prevent the installation of other ROMs such as custom ones. By default, the bootloader restricts the execution of third-party custom ROMs and modified versions of the system, and will only allow the boot of the authentic operating system that is running through an officially signed image.
Behind every problem on an Android system, there is always a solution, so in order to run a custom ROM, you should first unlock the bootloader, which will allow the “unauthorized” operating system to start in this case. Given nature open source For Android, each manufacturer develops a different version of the bootloader for each of their devices, depending on their specific hardware. The method of unlocking it varies by manufacturer, including some of them, which provide different procedures.
LThere are several reasons why a user might want to unlock the bootloader and thus eliminate the imposed restrictions. In general, most decide to unlock the bootloader in order to then install third-party Custom ROMs with the simple objective of enjoying the extra functions on their phones, or simply to update the version of the Android operating system when the terminal has been rooted. and in this way you cannot update it via OTA, or the device has reached the end of its days regarding support.
Se can unlock the Bootloader. You can indeed unlock the Bootloader, but for this we need a developer to provide the so-called exploits necessary to do so. Exploits are pieces of software or data fragments, used to exploit a security vulnerability in an information system to achieve unwanted behavior. However, the process of unlocking the bootloader is risky and can put devices at risk.
