Special boot modes
Recovery: With the device powered off, hold Volume Down + Power. When the LG logo appears, release both buttons and then hold them again. Then answer YES to erase all user data & restore default settings (If you have LineageOS Recovery installed it will not delete anything).Note: Accept the factory reset prompt using the hardware buttons. If you have done everything correctly, this will not actually reset your device but instead will boot the custom recovery.
Bootloader/Fastboot/Download: With the device powered off, hold Volume Up and connect the USB cable.
