The New Genesis
Ok, so one of the main add-ons for Kodi; Genesis, has been abandoned by its developer. Fortunately a new developer has created a new fork of the add-on; Specto-Genesis Fork.
First, uninstall Genesis. (Note: > means to click on the link that follows)
Open Community Portal > Install Content > Install Add-Ons >
[Manual Search] Type in Author/name/content
then Type in Genesis > Specto - Genesis Fork > [INSTALL - Recommended] Specto - Genesis Fork
If that doesn't work then try;
[INSTALL - Backup Option] Specto - Genesis Fork
Once it is installed exit the community Portal.
You can find Spectro-Genesis Fork by going to add-ons > Video add-ons > then find Specto-Genesis Fork > Click on it then hit Launch.
