Is there any Android 4.1.1 ROM for this TV Dongle? If not, would it be possible to cook one?

I would like to have the old Bluetooth stack working again so I can use wiimote.

I guess I could do it by myself but I'm not that familiar with the End2End Android build process. For a start, I don't know what kernel configuration should I use for this device.

Can someone give me a hint?
