By unlocking the bootloader you can open up a whole new world of possibilities. An unlocked bootloader allows you to modify the system data such as the recovery or the operating system. You can not only root the smartphone to gain admin/superuser privileges, but also install a different ROM which can change the overall smartphone experience. That said, all these possibilities depend on the developer community, and some devices receive more development, while others receive lesser.
To ensure that the smartphone is properly detected by the bootloader unlock tool, make sure you install the required fastboot drivers. If you are not sure whether the drivers are installed or not, please run the drivers installer again.

And, when portability ends, you can call your operator and say that you want to release the mobile, for which it is usually assigned a release number with which to carry out the process.

Well, Sony has made moves to make it possible to do this after the end of the tenure period, but it has a certain complication. We explain step by step.

As an example of why it's useful, see the recent iOS boot ROM vulnerability which allows an attacker with physical access to run arbitrary code on the device at the CPU's highest privilege level.Because the device is locked down (i.e. there is a secure boot chain that starts with Apple's public key stored in ROM, and the boot ROM verifies the bootloader which verifies the kernel which verifies the system which verifies the apps) it can't be turned into a persistent exploit - the device will always be in a good state (or bricked) after restarting. That gives reasonable protection again evil maid attacks (e.g. when someone tries to install malware in the factory or during delivery or in border security checks (remember to restart your device when you get it back), or before selling a device as second-hand, etc) and allows regular users to trust their device. It's still a bad vulnerability but it would have been much worse without a locked bootloader.> Look on how Huawei first promised to unlock bootloader on Mate 30 Pro and then decided not to do that, in the end.I assume most people wanted an unlocked bootloader so they could sideload Google apps onto it (which aren't installed by default because of US trade restrictions)?
