I'm rooted, MF9. I was fine yesterday, and no changes have been made.
i'm using philz recovery. I have wiped the phone "prep for new rom" and flashed a fresh stock odex rom and there wasn't any change.
LTE data is working but phone calls and text just won't work.
Edit- Also just to note i have 4 other guys in my office with Sprint Galaxy S4's and none of them are having issues.
