Guys, I unlocked my Sprint Note 4 successfully on 5.0.1 (OF5) using the idone app. Later I Odin it to stock COG5 5.1.1 tar. Once I did that, my hotspot and roaming options disappeared from settings. In order to get data working on my operator (non US CDMA), I had to write a dummy NV Dump and had to change few other parameters (trial n error). I finally got data working but I changed too many parameters. So I decided to ##RTN#, so that I can reset back those parameters and start fresh from begining.
Right after the reboot, it started to display "invalid card". I tried different sim but same result. I tried to Odin back to stock COG5 tar but it didnt help. Now that I'm on 5.1.1, I'm unable to use idone app to sim unlock again. And since I'm on COG5 firmware, cant downgrade as well.
Please help me out guys.
