Well, except in my case, it grenaded my phone's ability to do it's ringer and alarms. It will vibrate, but refuses to even try and play back to ringer files, giving an error message saying it can't play the file.
It's odd since everything else will play sound...
Off I go to see if I can figure it out...
Edit:
Updated TWRP... 2.8.6.2 to 2.8.7.0
Reflashed HK mod...
Ringers/Alert Sounds work again...
Guess the patch breaks something, so until an official Sprint patch for the HK phones comes out, it's either secure BS or insecure HK.... :-/
Have you tried this?
