1. Magento 2.x. How to install theme using fullpackage

Login to your Hosting Control Panel and navigate to the File Manager section.
Upload the fullpackage.zip file to the root of your server or, alternatively, to the subdirectory.
Upload the unzip.php file, provided within the template download package. Alternatively, you can use the Unzip/extract option provided by hosting cPanel.
Access the unzip.php file using your browser: http://your_domain.com/unzip.php.
Choose a fullpackage.zip file to unzip it into the location you need.
We should import the sample data via phpMyAdmin tool.
Select your new database, created for Magento site and browse for sources\sample_data\themeXXX_xxx.sql file provided with the template download package.
Visit your site URL after the database .SQL file import.
NOTE: in case you’ll receive a blank page or an error, then you must adjust Base URL value in your database.
Go back to your phpMyAdmin tool and look for core_config_data table. Click on it to edit.
You should change values for:
- web/unsecure/base_url
- web/secure/base_url
Reload your site and proceed with the installation.
Note: If you receive PHP Version Check error, then you should change the permissions as follows:

- All files have 660 permissions. 660 permissions mean the owner and the group can read and write but other users have no permissions.
Click to Try Again when permissions have been changed.
