Maybe try removing the w5100. I don't know what it can be, eeprom appears ok as you can run pre-update, if eeprom was bad or not seen pre-update would take an hour to run. I sent another sketch that will set all eeprom locations to default 255. Upload to display and controller and wait till it says finished. I added an extra eeprom check when it finishes to verify the eeprom is still functioning.
After doing that upload v5.12 and see what happens.
If no go upload pre-update to both, then again v5.12 and see what happens.
