用binwalk2第一次分析，然后解压出来得到文件名为8C的文件。
DECIMAL HEXADECIMAL DESCRIPTION
--------------------------------------------------------------------------------
76 0x4C uImage header, header size: 64 bytes, header CRC: 0x31E3AA7C, created: 2015-05-28 15:24:02, image size: 6920927 bytes, Data Address: 0x80000000, Entry Point: 0x8000C2F0, data CRC: 0xE6A4E643, OS: Linux, CPU: MIPS, image type: OS Kernel Image, compression type: lzma, image name: "Linux Kernel Image"
140 0x8C LZMA compressed data, properties: 0x5D, dictionary size: 33554432 bytes, uncompressed size: 10035720 bytes
第二步：查看得到8C文件类型。
file 8C
8C: data
用binwalk分析并解压，得到好多文件。3EFFA8.xz ，403A58。。。到404850.
我用ghex看了下应该是把8C 从0x3EFFA8至文件尾分离得到3EFFA8.xz 。从0x403A58到文件尾得到403A58。

第三步：然后又分析了3EFFA8.xz 。
file 3EFFA8.xz
3EFFA8.xz: XZ compressed data
尝试解压失败
xz -dc 3EFFA8.xz
xz: 3EFFA8.xz: Compressed data is corrupt
