you have to keep in mind the device still doesn't even have a custom recovery yet(neither has it been released worldwide) and lg put in some interesting things on the phone, other than the fact the bootloader is locked(just like the g2, g pro2, g flex, etc) there seems to be some more partitions in there(2 bootloaders, 2 root checking related partitions, etc) the g3 is going to be a tuff nut to crack and it will take some time for development to move the way people would like it to especially in the custom rom department, and we can expect that after the us/uk variants launch we will see some progress but if you want the device for aosp then get a nexus
This surely must be closer. Custom recovery is now available (if I am correct) ....
Custom recovery is not yet available. The T-Mobile variant bootloader came factory unlocked, so they will have TWRP shortly and custom AOSP/AOKP ROMs and kernels soon, but none of the other models yet. It could be next week, could be next month, could be next year for the rest of us.
I'm hopeful that it will be within the month, it seems like quite a few devs are attacking it. They're starting with universal root first though, so we'll just have to be patient.
Over the years: Samsung Blackjack 2 -> Samsung Jack -> HTC Pure (TouchDiamond2) -> HTC Aria -> Motorola Atrix -> HTC One-X -> SGS3 -> LG G3
