[How to] Install Official CM 12.1 (Android 5.1.1) on LG Optimus G

LG Optimus G is LG’s late 2012 flagship phone. It is powered by quad-core Qualcomm Snapdragon S4 Pro processor. The speedy processor is backed by 2 GB of RAM, 32 GB of ROM, a 4.7″ “True HD-IPS+” panel, LTE connectivity, a 2100 mAh battery, and an 8 or 13 MP camera (depending on region).
