JUSTOP K10A Quad Core 1.6GHz

[O.C.2]

Hello, anyone got this mini pc?? I have this one (http://www.amazon.co.uk/JUSTOP-Andro.../dp/B00D6LEABA) but with 4.2.2, not KitKat and I can't identify what version it is (1.6 or 2). The official forums (which are dead) say something about red, green or no sticker on the side, while mine has a silver "cozyswan" sticker. I wanted to update to 4.4 hoping it will play HD videos smooth (because now its useless as a media player..). Any idea what to do?
I would even stick on 4.2.2 gladly if video playback was ok

Ok I'll post the solution that worked for me just in case someone needs help.
After verifying it had the ap6210 wifi module (even with silver sticker) I updated to KitKat (justop_k10a_ap6210_4.4.2_1080p_V1.7_27082014) and HD playback seems to be finally smooth
