I have downloaded the Android 4.4.2 Kitkat torrent image from this website several times. When I go to write it to SD card, whichever program I use, it stalls and doesn't get past 0% complete. I've let it sit over an hour to see if it is just slow, same result. I have used Win32 disk imager, etcher, unetbootin, isorecorder, and one more that I can't remember. What am I doing wrong? I'm using Udoo Quad, and I am able to write the udoobuntu image to the sd card just fine and it works. I'm also having problems with the sorceforge and mirror images. I have tried 8GB and 64GB SD cards.
