Keep trying different mirrors or try "desktop view" should work if that doesn't the way I got darthstalker to download after trying 6 times was using dolphin browser saving it to my sd card and download it I noticed my connection was dropping on wifi so I played a YouTube movie to keep connection going. Download was then successful
