No, that can not be done, the files contain your customer info.
Just follow the instructions, it tells you specifically how to do it.
Maybe try to disable your hooks to see if you can log into the ACP.
Open your config.php and below<?php add this line:
PHP Code:
define('DISABLE_HOOKS', true);
So it looks like this:
PHP Code:
<?php
define('DISABLE_HOOKS', true);
