Printer doesnt work after firmware upgrade screen with black blocks

Hii,
I Bought an Aurora Z630 from a friend.




I connected it to ReplicatorG and came across the firmware upgrade function.
I did firmware upgrade and said succes.
Now I cant connect to the printer and the screen shows 2 black blocked lines.
Connected by USB computer spots COM3 but doestnt connect with ReplicatorG.
Firmware upgrader gives error now.
Firmware downgrade with winbottool worked but still screen stays same and doesnt connect with replicatorG.

Anyone with tips?

You have probbly just upload atmega firmware into an arm device...

You need to get firmware from whome ever supplies that board, (which I have been unable to find from googleing)
