I've searched the known places where developers publish their ROMs, but there isn't anything available. I've seen some ROMs, but they were actually stock ones used to flash the original firmware onto the device.
You can download these stock roms from the XDA Developers website where most of the Android troubleshooting and support is taking place.
Tip: The website's search module is heavily optimized which means you should use it to look for roms.
