Hi,
I followed this procedure and upgraded to Jelly bean and the device is running pretty fine. Today morning i gave a reset to the device as i am going to give the device back to my mother. Once i given the reset i am shown the unauthorized software message and the device doesnt boot also. I tried to re-flash the device with the Original ODIN and i got success and device got booted perfectly fine.
The problem now is its not detecting my Verizon LTE sim card, one moment the signals come and then reduce and completely vanish. Not sure what has happen. Was there any issue with the radio please help me
