Samsung refrigerator RF23M8570SG, stopped working after software update

[Bayareaguy]

Hello, I have Samsung refrigerator RF23M8570SG. Touchscreen is not responding, no lights in refrigerator, not cooling. 

I tried: 

- reset power to refrigerator

- use reset bottom in the hidden compartment on the door.

- reconnect all connectors.

I found a usb slot next to reset bottom, maybe there is a way to download software and try to reset it that way, my other guess is to replace main control board. Did someone encounter this situation, thank you for your help

Also there is power to the fridge

I have same issue. Do you remember if main board fixed it?
