0 0x0 TRX firmware header, little endian, header size: 28 bytes, image size: 14577664 bytes, CRC32: 0xF1AEBE86 flags: 0x0, version: 1
28 0x1C LZMA compressed data, properties: 0x5D, dictionary size: 65536 bytes, uncompressed size: 4867904 bytes

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
