I did the original root for the d4, where you downloaded the auto.bat and let it run through. After completing the OTA my phone worked fine until like 3 days later. I noticed I can not get into TiBu, Nor does my wireless tether work. They are both saying I lost root. I still have superuser but apparently no root. Then to top off my problem I have no internet other than WiFi. I have tried to force CDMA and still nothing. I am in a good 4g spot. My wife has the same phone but completely stock and hers has 4g when my phone is right next to it with nothing.
Any suggestions. was thinking maybe going through the ADB shell and getting rid of the super user and trying to root through safestrap???
Thanks for the help!
