Also, you may know this already, but after the install completes you need to turn the camera off and back on before the 20 second timer runs out on the ML install menu or it won't run. So as soon as it says install complete then turn your camera off and back on immediately. Don't take the card out yet either. So power off the camera, power it back on, wait a few seconds, then press the camera's menu button once, then press the trash can. See if that works. Just trying to offer ideas...
