@nathanvonbeerenstein they should all come flashed with the latest version unless this is the previous gen where it could have done with a firmware upgrade. What happens when you connect it to USB power and use something like Termite to monitor the device's COM port on start up (this is probably the most important things to do)? There should be an error message of some type usually. It may be worth running an erase and re-flash? What settings do you have in the Advanced tab?
