Question

Magento Version: 1.6.0

Answer 1

To reset a module data, you have to delete it’s resource related entry, this way magento will rerun setup script again.

Example:
Let’s say you want to reset the newsletter module data.

If you check

app/core/Mage/Newsletter/etc/config.etc

You can find

<resources>
    <newsletter_setup>
        <setup>
            <module>Mage_Newsletter</module>
        </setup>
    </newsletter_setup>
</resources>

This means the resource name is newsletter_setup

Log in to your database, find the table core_resource, find the entry where the
code = newsletter_setup delete it.

Now if you refresh the page, Magento will run the setup script again, in this case, it is

app/core/Mage/Newsletter/etc/sql/install-1.6.0.0.php
