What is a bootloader?
A bootloader is the first software loaded on your device. After that, the manufacturer usually locks it to ensure that no one else can modify the system without permission.
Bootloaders are responsible for loading the operating system kernel (OS) into memory. If there is an error or the OS is corrupt, a bootloader can help you restore the system to a known good state.
When we say "unlock the bootloader," we mean to unlock the security that prevents us from installing mods in it.
This is done by replacing the existing bootloader with a custom one. This means that your phone will boot any file we want it to, not just the files that are already on your device.
The disadvantage of Unlocking Bootloader
As mentioned earlier, the bootloader is not accessible by the user and thus cannot be tampered with. The bootloader prevents tampering and prevents users from installing third-party apps, such as rooted apps.
For example, if your phone’s bootloader is locked and you forcefully install a custom ROM, your phone will not startup. This will happen because the custom ROM has overridden the boot sequence of the phone.
Not to forget that an unlocked bootloader is a security issue.
Unlocking the bootloader is a good idea only if you want to install custom ROMs, kernels, or other mods on your device.
