Did I brick my Rabbitcore?

I’ve got an RCM3200.

I bought RabbitSys for the easy remote updating.

I changed the SystemID on the RCM3200 to that of an RCM3365, as it said in the manual.

The RCM3200 now won’t function anymore. The ethernet adapter is screwed, the LCD display won’t do anything anymore.

Why? What happened? I did exactly as it said in the manual and I bricked my Rabbitcore? Nice one!

Please answer me, Rabbit!
