All modules/kits come with the latest firmware version loaded. You ordered in June so your kit has with the latest version and no reason to update.
You ordered the Minimal kit, which means it comes without any external components like cabes, LCD, controls and etc. As such I suspect that you didn't wire some of the cables correctly. Most likely LCD is not wired correctly or it is faulty. I would suggest to doble/triple check it (and all other wirings). With wiring correct and good LCD it just works.
