I have a SharePoint list, I saved its template, downloaded it and renamed the .stp extension to .zip.
After that, I extracted manifest.xml file, edited it and changed the list's GUID.
After that, I added the manifest.xml file to the archive, renamed it to .stp and uploaded it to the SharePoint site.
But when I am trying to add this list, it doesn't appear in Add apps.
Here is an image of how it is displayed in List Template Gallery:
