到目前为止，所有看起来都有效，但我尝试了以下内容：
root@kali:~/ROUTER# lzma -d uboot.lzma
lzma: uboot.lzma: Compressed data is corrupt
root@kali:~/ROUTER# unsquashfs kernel.squash
Parallel unsquashfs: Using 4 processors
lzma uncompress failed with error code 0
read_block: failed to read block @0x277af0
read_fragment_table: failed to read fragment table index
FATAL ERROR:failed to read fragment table
知道为什么会这样吗？如提示所示，我在Kali Linux上。也可以这个

答案 0 :(得分：1)
尝试
lzma -d < uboot.lzma > uboot
您发现的错误是由于LZMA Utils已被XV Utils取代，后者不会忽略尾随垃圾。如果你将它用作流（就像我给你的那样），你最后仍然会收到损坏错误信息，但你会得到你的文件。

答案 1 :(得分：-1)
试试
binwalk -e new-firmware.bin
你最终会解压出 2 个文件
在提取的一个中，你会得到 2 个解压缩的和一个压缩的 此时你可以使用 dd 并且 unlzma 应该可以工作，至少它对我有用
这就是我的意思
