Seeking Brooklyn Board repair or replacement for MakerBot Replicator 5th Gen.

I am trying to revive a 5th gen Replicator for an elementary school. The USB port has come off the board and that being the same board as the Network port it has damaged that as well. I have had no luck getting a usb drive to work as the machine recognizes the usb stick but says there is no files.
My procedure for usb has been to import the .stl in to MakerBot Print, place the model and to export it to the usb drive. I have done this having formatted the drive to Fat32/MS-dos with no luck.

Any insight on this would be appreciated.

doesn't it have an sdcard slot ?
