all looks have worked far try following:

root@kali:~/router# lzma -d uboot.lzma  lzma: uboot.lzma: compressed data corrupt  root@kali:~/router# unsquashfs kernel.squash  parallel unsquashfs: using 4 processors lzma uncompress failed error code 0 read_block: failed read block @0x277af0 read_fragment_table: failed read fragment table index fatal error:failed read fragment table 

any idea why may happening? prompt says, on kali linux. this

try

lzma -d < uboot.lzma > uboot 

the error found due lzma utils having been superseded xv utils, don't ignore trailing garbage. if use stream (like gave you), you'll still have corruption error message in end, you'll file alright.
