rom help for mk809iii with odd BT and WiFi chipset

I have kind of an oddball MK809III, it has a RK3188-T processor, a MT6622N for Bluetooth and ESP8089 for WiFi. I found a rom where everything works, but it's quite unstable.
Just wondering if anyone has a decent FW for this thing, LP would be awesome, but I might be dreaming.
Any ideas?
