逆向工程 - Unsquashfs 中途失败，gzip 错误代码 -5 - 吾爱随笔录

我一直在尝试解压缩 system.sfs 文件以修改目录。但是，unsquashfs system.sfs返回以下输出：

Parallel unsquashfs: Using 8 processors
1 inodes (16000 blocks) to write

[===========================================|                                        ]  8386/16000  52%
gzip uncompress failed with error code -5
[=============================================================-                      ] 11906/16000  74%

它一直挂在那里。在我强制终止解压缩过程后，我得到了一个system.img文件，但是，它是部分文件，无法作为有效存档进行处理。我已尝试遵循本文中的建议，但没有任何工具有助于解决问题。 hexdump system.img不会产生任何异常输出（除了它停止的地址可能是 [0x4CCA0000]？）：

当我发出binwalk system.img，输出看起来很平常，直到文件结束，产生：
