I have a firmware that I've dumped from a phone. I found a uImage header and a zImage after running binwalk. The header says that the image is uncompressed, however I've read that zImages are usually compressed with lzma, xz, gzip, etc. Does this mean the zImage is uncompressed and I can work with it directly, without decompressing it?
