I don't know if you knew this but LG C800 has a Recovery Utility. If you want to try it you could but I would recommend backing up your device. You probably already know how to factory reset (A+F+Volume Down+Power). I was doing that and when it showed the picture of the android unboxing I hit the home soft key and it brought up the utility. All it say is
reboot system now
apply update from sdcard
wipe data/factory reset
wipe cache partition
You scroll with the volume keys and you select with the enter button.
Maybe this is a new discovery and if it is then we could possibly get a custom roms.
