Created page with "A bootloader is a program that runs when the phone turns on and loads the operating system. <ref>{{Cite web |title=GNU Grub website |url=https://www.gnu.org/software/grub/index.html}}</ref> Most phones lock the bootloader by default, which means that a new bootloader or operating system can't be installed on the phone. <ref>{{Cite web |title=Lock and unlock the bootloader |url=https://source.android.com/docs/core/architecture/bootloader/locking_unlocking |website=Android..."
 
How it works: Added link to the already existing Bootloader Unlocking article.

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
