Of course, try other images, I think notlist3d suggested some other image. You should know that standard SD card for these rigs as they come from China is Sandisc Extreme 8GB Class 10. I've tried the image in question with the regular one (Class 6 8GB) and it worked as well.
I don't know what is wrong in your case but definatelly tested this image and it works - actually I am using it right now for all of the 1T Dragons because of the low BTC prices - to underclock them.
Keep us posted if you find the issue.
