"Access denied" probably means your browser isn't allowed to access the USB ports. I notice Mint is not on the list of known-good installation platforms, and there may be a connection. Did you install udev rules?
Other things you could try: running the installer on another Android phone; running your browser as root; doing a CLI install (though if you go that route you do need to be careful to follow directions carefully and in order).
