I was trying to fix the issue where you cannot download from torrent apps on kitkat. I found this post, http://trendblog.net/fix-kitkat-sd-card-write-restriction/, and modified my platform.xml file. After restarting, I was unable to get to my external storage. Most of my apps were crashing. I finally had to restore from my TWRP backup.
Note to self - Don't try modifying system files!
