ok...upon looking into this a little more I have a question.
Am I supposed to extract the file containing the image twice? It starts as a tgz, then when I extract it it's a tar, and if I extract THAT I get a folder containing the image-mysid-icl53f.zip plus the other .img files that are needed.
I think maybe I answered my own question.... But if that's not right, someone lemme know please!
