Same issue with update, only I lose data
I used Odin to go back to stock MDK, then when I take the update from Verizon, it fails as OP states and I lose data. No 3G or LTE. Have to erase everything in the Odin back to MDK stock to get it back. Any suggestions? Not in too much of a hurry, but concerned that I'll never be able to get to the new radio and firmware.
Update: I lose data when I set up Wi-Fi the first time after restoring. Had data when phone first booted in setup mode, then after setting up Wi-Fi, goes away. Must have some mucked setting somewhere.
