Unable to log into site after changing site URL

My coworker has recently changed the site URL of our wordpress site, and now none of our log in details are working. I tried hard coding the site URL in our wp-admin.php file with:

define('WP_SITEURL', 'www.myuluru.me/myuluru.me/');
define('WP_HOME', 'www.myuluru.me/myuluru.me/');

But that just made the wp-admin login screen go blank. without adding this to the php file, none of our log in accounts seem to be working. Any assistance would be greatly appreciated!

We did this while trying to change the front page of our site away from a blank hello world screen. again, the site is: myuluru.me
