How to get into a Drupal 7 site using only Drush without touching code or anything else?
What I did was change the default theme to the basic seven theme:

drush @mydomain.dev vset theme_default seven

Then reset your admin password:

drush @mydomain.dev upwd admin --password="mypass"

Then go and find a page that loads the seven theme and by default the seven theme has the login block somewhere in the footer area. Login with admin and your new pass! =D

If you have a theme switching module, you'll have to turn that off too. Such as themekey or rules or securepages (this is what was causing my issue.)
