unlocked
By unlocking the bootloader, you will be able to install custom operating system on this phone. A custom OS is not subject to the same level of testing as the original OS, and can cause your phone and installed applications to stop working properly.
Software integrity cannot be guaranteed with a custom OS, so any data stored on the phone while the bootloader is unlocked may be at risk.
To prevent unauthorized access to your personal data, unlocking the bootloader will also delete all personal data on your phone.
Press the Volume keys to select whether to unlock the bootloader, then the Power Button to continue.
