Hello, first thing is we should make sure the MRCC 880 is working correctly. There are no firmware updates for the MRCC 880, so I don't know what you tried to install.
If when powered on it is stuck on Input 4 LED, then the firmware is messed up somehow. If it boots to Input 1 LED, and pressing Input 2, 3 or 4 changes the input, you are good to go. It sounds like it is working if it lights the LEDs in sequence and lights Input 1 LED when it is booted up.
