Unfortunately there is no flashable stock image for the Samsung Focus S. You cannot use the backup from someone else's phone ad they are uniquely identified and will only work for that particular phone.
I'm not sure why you're getting that error as its all in Spanish but my guess is that you don't have all the correct files for the install.
Really, you're on version 8107 so I see no reason the upgrade won't work for you provides you follow the instructions exactly.
