fully wipe factory reset?
or try the earlier one
Its the same for me. Only Houston's 4.1.2 stock leak based off the Korean model work for me. AOKP, CM10 or any aosp ROM won't boot on any canadian optimus if you are on lg's latest firmware update release. You apparently have to kdz downgrade, even if you unlocked the boot loader and rooted, and have flashed houstonns leak. Its weird I know. But something about LG'S update I think messed with something in the boot IMG. I dunno, I don't know enough, lol.
