How to completely uninstall and remove your BindTuning Farm Solution Theme

BindTuning products offer several deployment options, to accommodate your organizational infrastructure policies and architecture. This holds especially true for the Design feature, and correlative installation scopes.  

When choosing the best approach to deploy your BindTuning theme on a Classic Site and/or page, you'll be given the option to either deploy the theme's Sandbox solution (deployed at the Site Collection level), and Farm Solution (deployed at the Farm level).

This article covers all necessary steps for uninstalling and deleting themes in SharePoint On-Premises 2013/2016 and 2019, while utilizing the Farm installation method.

Uninstalling the theme

1. Start by reseting the master page to a SharePoint default master:
   • On the SharePoint ribbon click Settings;
   • Click Site Settings;
   • Select Master page;
   • In the first two options select the "Seattle" master from the drop-downs
   • Make sure to check the option "Reset all sub sites".
2. Now you must deactivate the theme package:
   • On the SharePoint ribbon click Settings;
   • Click Site Settings;
   • Under Site Actions select Manage site features;
   • Locate "THEMENAME Theme Package" and click Deactivate;
3. And finally, remove the theme package:
   • Run the SharePoint Management Shell as Admin, in your server;
   • Go to the path where the theme .ps1 script is located;
   • Run .\Install. ThemeNamePackage.ps1;
   • If prompted, accept the "Execution Policy Change";
   • Select option 2 and wait a few seconds. SharePoint will retract the solution. During this process, if you try to access the site it will return a 503 error.
   • Run .\Install. ThemeNamePackage.ps1;
   • Select option 3 to completely remove the package from the solution store.

Deleting the theme

1. Start by validating the uninstallation process was successful:
   • Click Settings > Site Settings > Manage site features and confirm the theme feature is deactivated;
   • Click Settings > Site Settings > MasterPage and confirm the Seattle masterpage is applied.
2. Retract and delete the solution:
   • On the server, open Central Administration;
   • Go to the solution gallery /_admin/Solutions.aspx;
   • Check if file THEMENAME.SP201x.wsp is in this gallery;
   • If it is, click the solution, and retract it;
   • When the retract job is finished click in the solution name again and delete it.
3. Manually delete remaining files:
