I have installed FMK and binwalk. FMK have an old binwalk that does not work. So, I ran a fresh binwalk (from git) as follow:

$> binwalk -e wr741ndv4_ru_3_13_2_up_boot(140521).bin

And in the directory _wr741ndv4_ru_3_13_2_up_boot(140521).bin.extracted/

$ls 
120200.squashfs  20400  20400.7z  3CEC  3CEC.7z  squashfs-root  unsquashfs

Then I compile unsquashfs with LZMA_XZ_SUPPORT = 1:

$> ./unsquashfs -v 
unsquashfs version 4.2 (2011/02/28)

$> ./unsquashfs -h
SYNTAX: ./unsquashfs [options] filesystem [directories or files to extract]
[...]
Decompressors available:
gzip
lzma

Then, I have an error to unpack squashfs:

$> ./unsquashfs 120200.squashfs
Parallel unsquashfs: Using 1 processor
lzma uncompress failed with error code 9
read_block: failed to read block @0x23d12a
read_fragment_table: failed to read fragment table index
FATAL ERROR aborting: failed to read fragment table

What did I do wrong?

P.S. If anyone have unpacked squashfs with this version firmware, please share it.

  • Does not work. It's extract old files 120200.squashfs 20400 20400.7z 3D10 3D10.7z squashfs-root/ and unsquashfs not extracted files from 120200.squashfs
