Direction on where to downgrade Android security patch?

I'm wondering where I can downgrade the security patch for my tablet below.
There is a game I like to play but I do not have any real time to spend on because I work a lot and do not travel besides on my way home late in the day.
Can someone give me direction on how to fix this? I heard that this security patch is the one that allows games to detect the developer mock locations.

Thank you all for any help that you can give
