Yea, this is an LG  Parameter of which, if it weren't a Tracfone,  would apparently be a prerequisite for unlocking your Bootloader.  Funny how this one goes -  even the peeps that know about it don't really know what the term  OEM Mode  means. I would think that, on normalized LG models on normalized carriers, you turn that  ON  and, you're past that sophisticated Unlock code that creates logistical nightmares from thin air . At that point, you're logistically Unlocked .  But, not with Tracfone. Gotta be one of the more freakazoid Telecommunications companies I've ever seen go past me. If you have any tidbits on how to install TWRP onto an LGDestiny,  please feedback cause there's virtually no starting point for me to begin at. Most of the peeps here don't realize what it's like to do Dev work . None - it would scare them away .
