Proxmark 3 easy device/fw mismatch

Purchased one of these from the dangerous things shop to bring to defcon last summer but never ended up messing around with it that much. I recently tried to set it up again for my mac and I got a Device / FW mismatch upon starting the PM3 program (i must have flashed it for some reason back when but oh well) , how should i go about reflashing it?

You’ll find a link to a doc in this thread : Getting started with Proxmark3 on Mac
