Android - Workaround for Android 4.4 not being able to write to SD cards?

Found an answer to my own question! Might as well share how I did it (DO IT AT YOUR OWN RISK, it worked fine for me). Needs root obviously.

1. Using a root-enabled file manager, navigate to /system/etc/permissions
2. Edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.
3. Add an additional group definition for this permission...<group gid="media_rw" />
4. Save the changes to the file.
5. Restart.
