I don't know why you're explaining all of this. You clearly misunderstood my problem.
The patch was on my phone and working perfectly. I was able to unapply it and reapply without problems.
What I couldn't do however was uninstall it using Warehouse as the patch has been removed from Openrepos.net some time ago.
The only option left was the terminal for which coderus was so kind to give me the proper instructions (Thanks again Coderus).


What this shows is that the system has a flaw. If a developer removes software from Openrepos.net, people who have this software installed on their phone can't uninstall it using Warehouse. They will have to resort to the command line.

Not a problem for me but there are enough people who don't know what a cli is.
