Thanks for the reply. When I boot it with the arrows held down it goes into the update mode but it keeps saying "Searching for an upgrade file, Please Wait". I left it for 20mins before cancelling it as it didn't seem to find the update file. the usb has a light that was just solid red the entire time if that gives any info.
When I go into the usb host mode option it doesn't come up with a upgrade option it just shows some text which I guess is some version info.
I have included photos to see if that gives you any help.
