Oaky so i have found a way to enable devmode (visual menu included) on latest 5.4 fw, all you need to do is replace /usr/local/Kobo/branch file with a file that doesnt contain "release/" easiest way to do this is

echo "devmode" > branch
tar -czvf Kobo.tgz branch

then put Kobo.tgz into the .kobo folder on your reader.
Make sure to also do the devmodeon dance
