我找到解壓縮錯誤的問題了,根據http://forum.xda-developers.com/showthread.php?t=756513&page=50的訊息,The files are compressed with the newer LZMA2 algorithm. You need to use the new 7-zip 9.xx builds to extract the files. With only support for LZMA1 the applications are only able to show you the content of the archives but they can't extract them. (Speedcommander acts like this.)意思是說要使用7-zip這個軟體來解壓縮,且要9.XX以上的版本(該軟體上述的網址有提供),我已順利解出,以上供參考。
