You will need to tell us more about how you tried to restore. Do you have a copy of the moodle database, moodledata folder, and even moodle?
Softaculous might fine for your very first install of Moodle, but we all kinds of problems with it whenever people try to upgrade. My guess is that Softaculous is just not smart enough to handle a rather simple task of upgrading, probably because of the many ways people modify their moodles.
