I just got an LGOG this morning, rooted, unlocked (both bootloader and carrier), installed TWRP, then got Carbon's latest nightly and houstonn's Adreno kernel working great tweaked out with some Trickster mods and at this moment it's just fantastic (of course I've only had it a few hours but it's damned fast and snappy, hence my sig now).
To even hope that Kit Kat would be coming for this device is pretty amazing, and considering it's definitely got enough power and resources to handle it, I would love to see it actually happen.
If not, 4.3 is gonna work just fine for me, but bring it on, Google, gimme a Kit Kat.
This is not the first mention of this either, there's another thread or two that I tripped over last night doing all the research before I committed to getting this LGOG earlier, so... a Mod may come along and clip this or merge/move it, just so you know.
Currently using a Samsung Galaxy Express (again) with CM11 Official Snapshot M5...
