Locking the bootloader
Locking the bootloader is important as it enables full verified boot. It also prevents using fastboot to flash, format or erase partitions.

If changes are detected, error correction data is used to attempt to obtain the original data at which point it's verified again which makes verified boot robust to non-malicious corruption.
In the bootloader interface, set it to locked:
