Projector NPX320

I own a Philips NeoPix 320, a fairly good projector for external HDMI source. However the internal Android OS is pretty glitchi, the preinstalled apps are not running smoothly and it fails when updating to its newest Firmware. Although it downloads it, it later gets stuck in bootloader with unsuccessful installation. I thought I could update over USB but the firmware is not available on Philips web.
Does anyone have an experience with it? Or possibly does anyone have an updaded firmware?
