Did all of those steps on several occasions and still nothing. 

Please check if you find the "XDJRX2.UPD" file at the root of the USB device.
If you have any other letters such as "XDJRX2.UPD(2)", please change the name to XDJRX2.UPD.

Yes was very careful i did that. Still just sticks on the same black screen with "Connect USB storage device to USB1"

USB1 port works fine when in playing mode so doesn't seem to be an issue with the port as afr as i can see. 

How about seeing the following?

When you formatted that drive to FAT-type file system, did you also format it for MBR?

See this video.

That was the issue, didn't have it as a matser boot record but a GUID format... Cheers guys... all good now
