This thread, and all current work were @Eliminater74's. He has moved on, so I am going to pick up where he left off. He will be missed in the LG community.
TWRP Version: 3.2.3-1:
Replaced compressed kernel, so boot times are much lower.
Verified not working:
Wipe LG Lockscreen
kdzwriter (imported: said to possibly work for g6 and v30)
I am sure many more things.. Just give me time to work on it all..
