I'm not sure if that'd fix it but could be worth a try. IIRC its something like 'turnkey-init'. This will reset the root user, MySQL and Magento admin passwords (and phpMySQL uses DB user passwords, so the MySQL root password should get you in).
The only possible comlication maybe the updated Magento. I'm not sure how the scripts will react with Magento being at a newer version than TKL default. If Magento has left the config file(s) basically unchanged then it should work fine...
Try running firstboot scripts manually?
