A bootloader is a program that runs when the phone turns on and loads the operating system. [1] Most phones lock the bootloader by default, which means that a new bootloader or operating system can't be installed on the phone. [2]
How it works[edit | edit source]
Some manufacturers do not allow unlocking the bootloader even if the phone is not under a contract. Some manufacturers allow to unlock the bootloader on some regions, or require a payment or an online connection to unlock the phone. Some manufacturers may void the warranty or block certain features permanently if the bootloader is unlocked
Why it is a problem[edit | edit source]
If the bootloader cannot be unlocked the operating system can't be modified in any way which is not allowed by the manufacturer.
