I installed SuperSU by flashing the zip file from recovery. The Play Store picks it up and shows new versions of the app. The problem is, the newer versions of SuperSU causes my phone to go into a boot loop. I have already disabled auto updates for SuperSU but I want to go the extra mile and completely unlink it from Play Store so it doesn't show up in the list of apps with updates available. That way, I won't accidentally update it.
Titanium Backup has the functionality to do this but for some reason SuperSU doesn't show up in the app list on TB.
