NGL if updating the firmware on a Bitaxe was as confusing as flashing this Wio Tracker, my Supra would probably still be running whatever it originally shipped with.
Thought for sure I'd bricked this thing because the video I watched wasn't very clear that you need to transfer one file to the device to erase the old firmware and a separate file to install the new firmware, and if you're doing all of this on a Mac, it scares the hell out of you with error messages.
