1. Accept no OTA update
2. Install LG Drivers (non-verizon version)
3. Run IORoot, using steps here
4. Download and run Freegee app to bypass bootloader & install TWRP
5. Backup the EFS partition and save it somewhere, in case I bork everything afterwards
6. Don't accept any OTA
Is that the basic idea of the path of least resistance? As I understood it, accepting the OTA updates complicates installing a custom ROM later on?
