Warning: The LG G3 (T-Mobile) is no longer maintained.
A build guide is available for developers that would like to make private builds, or even restart official support.
Guides
- Installation
- Build for yourself
- Update to a newer build of the same LineageOS version
- Upgrade to a higher version of LineageOS (e.g. lineage-15.1 -> lineage-18.1)
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.
