For the community, this was the Rosetta Stone. Suddenly, the LG G4 became a universal device. You could flash the H815 LineageOS 18.1 (Android 11) onto a Verizon VS986. There is a morbid irony to the LG G4 bootloader unlocking saga. The primary reason users wanted to unlock the bootloader in 2016-2017 was not to run Linux or overclock the GPU. It was to stop the phone from killing itself .
PBL (Primary Bootloader - ROM) -> SBL (Secondary Bootloader) -> ABOOT (Android Bootloader) -> Boot Image -> System
By sending a specific malformed fastboot oem command (or using a low-level tool called LGLAF via Download Mode), the exploit flipped the UNLOCK bit. However, because LG signed the entire boot chain, simply flipping the bit wasn't enough—the phone would still refuse to boot an unsigned kernel.
