Thanks a lot, Kaos! I have downloaded and checked the "Quick Upgrade" files, I think it would have worked. However, I found another solution:
I "resoftmodded" the XBOX, since I don't have the pendrive cable, nor any original game which can perform the softmod, I copied the saved game files to the E:/UDATA and the "ROM" files of the game at E:/GAMES. Then I only ran the game and follow the instruction to softmod an original XBOX.
Everything seems to be updated and is working fine.
