Decided to make an account to help out here with all the confusion...
If you have Luma, when having patching enabled so you can use the English translation, you can't use NTR plugins. Trying to load the game with both NTR plugins and enabled patching will always cause an arm 11 exception handler message to appear and the device will then turn off. That means that if you want to use NTR cheats with the game you need to first deactivate patching in the Luma options menu. Additionally, just to clarify, there is no point in trying to use NTR to apply the patch since the method is now outdated.
Next up we got those people who are confused trying to extract and repackage the patch CIA so it includes the patch by using HackingToolkit9DS and getting errors when installing, the developer of it has said that the repackaging feature got broken in the latest version so you have to wait for the fixed one to come out. For example when I tried I got a botched CIA that gave me the error at around 70% through the installation. Haven't tested Vermil's links he mentioned above yet since I'm already on 1.2 anyway and don't mind turning the patch off to use NTR.
Finally, if you need a clean update CIA ready to install, just use google to find one. I have uploaded one I made with Decrypt9 on youtube (don't want to post link since new here), but you can tell by the name of the uploader if you end up finding mine.
