    1. Hey! Firstly, you use LGUp to flash VZ4 stock rom, then you root by Stump. And you can unlock carrier following this article: https://forum.xda-developers.com/sprint-lg-g3/general/unlock-sim-gsm-how-to-t2853594. Secondly, you install twrp recovery and backup efs partition. Last, you flash lineage os and you unlocked you phone.
      P/s: sorry my english :-(

    2. So I would lose the custom rom I currently have, and would have to do it all over again? Sprint gave me a unlock code to give to my new carrier, but I'm not with one yet, and I want to unlock it my self, but when I put in sim it does nothing.
