Bootloader lock

Last updated on 21 October 2024

A locked bootloader is a security feature implemented by device manufacturers that prevents unauthorized access to the device’s firmware. When a bootloader is locked, it restricts users from flashing custom ROMs or making other modifications to the operating system. This helps ensure the device’s integrity and security, as it can prevent malicious software from being installed.
In a locked state, users can typically only install official software updates provided by the manufacturer. To modify the device, users often need to unlock the bootloader, which can void the warranty and may lead to data loss. However, unlocking allows for greater customization and the ability to install custom ROMs, but it comes with associated risks, such as potentially bricking the device or exposing it to security vulnerabilities.
