I used Odin to flash MM image and everything is good, except the 3G data.
It will only turn on if I run "Activate this device" from Settings menu.
If I exit from "Activate this device" menu, 3G turns off while data toggle still on!
I'm not Sprint user and everything was ok with 5.1.1.
Any help would be really appreciated.
After exiting from Self service app :
Note that the 3G sign disappeared and no data also!
