How to fix error 13 on xbox original?

I tried softmodding an xbox with softmod installer deluxe (newest version). I was in the menu, and i backed up eeprom, c drive, but when I tried backing up ms dash it was saying couldn't find ms dash, or patch it. (something along those lines). I then proceeded to turning off xbox, and when xbox reloads/turned on, it loads error 13 with green words in different languages saying xbox needs service. It will still read games right away, and start them though (put in splintercell, and it loads it, and allows me to go to the softmod installer menu). But how do I restore/fix problem if there was never a msdash backup made, or softmod installed? Would putting in halo 2 update the xbox and fix problem? I also tried burning auto installer deluxe disc, but it will not read that, only games. The xbox dash/ kernel versions are: Kernel 1.00.4034.01 Version 0.39.022a build 572 unleash x (according to the softmod installer when I go to look at harddrive)
