[Magisk] Didgeridoohan:
Yes, chcon -R. It was of no use though, since it didn't work. Have confirmed that the folders are system_file, permissions are 755, but no dice.

I'm using SetDPI from the Module Collection thread (http://xdaforums.com/android/software/collection-magisk-modules-t3445257) and i saw that it already is set up to change the context (from what i can gather).

I must be missing something obvious. Here's the contents from my magisk.log in case anyone can make something out from that.
