Need a room for a Rockchip RK3066 stick? topic

Just bought a TV Stick with these specs
Specifikationer:
Chipset: Rockchip RK3066
CPU: AMR Cortex A9 Dual core 1.6 GHz
GPU: Mali-400MP Quad core
RAM: 1 GB DDR3
Flash memory: 8 GB
Memory card: Micro SD up to 32 GB
WiFi: 802.11 b/g/n
Android version: 4.2 .1Jelly Bean
Bluetooth: 2.1

The firmware preinstalled is a mess. And i wounder if there is any way to install a "Universal" room whom will work on this stick.
The brand is Andersson :s
I have googled and found out lots of firmwares from rockchipfirmware.com but dunno what to take? I want as clean as possible, and will be mostly using XBMC.
