Wonder if anyone can help - Ive tried to do this on the front USB and rear and it just ends up loading the GUI up and not updating anything. I have BH 2.1.5 at the moment and cant update the firmware at all. Hence me trying to do this first. It appears not to read the USB when booting up. Though when it has booted up and started it does recognise the usb as it says no media present on device.
