I have a galaxy light SGH-T399N VERSION 4.4.2... I rooted my phone and removed what was called Tethering Provision. Now when I try to Tether with the pre-installed app it takes me to mobile data and tethering. i check the box for usb tethering and it instantly gives me a message stating "unfortunately services has stopped" and returns me to the network page. I have tried to find Tethering Provision in the app store, Samsung store, every place but to no avail, somebody please help me. The third party app I'm using is killing me hotspot and tethering data! Thanx in advance.
