When I used IFA before if it failed to flash I thought you had to shut it down each time, then start it, select the image, select the network, and start all over again. This can take ages with a stubborn box (especially a kein system sagem). But if you follow this guide you can simply leave IFA running and just keep pressing the 2 buttons on the dbox to restart it over and over. http://techno-source.co.uk/Joomla/index.php?option=com_smf&Itemid=33&topic=12.0
