Dead Apacer AU851

[hostar]

Hello,
I have Apacer AU851 just one day.
I was sick of poor video support, so I google for some improvements.
When I try to connect to device via M5661ISP tool, player dies.

I haven't firmware and I can't find any on the net.
But if I run Factory4 tool, the device is detected on some low-level, so power supply should work.

Player chip is probably ALI 5668

Can someone help me get firmware file?

Thanks
