lets cut the trx header out
cli:
dd if=ea6200_direct.img of=trx_header.bin bs=1 count=28
we get n file called trx_header.bin
next lets cut the lzma out
cli:
dd if=ea6200_direct.img of=lzma.bin bs=1 skip=28 count=1990256
we get an file called lzma.bin out
so last is the rootfs
dd if=ea6200_direct.img of=squashfs_rootfs.bin bs=1 skip=1990256
