I have a Verizon S4 that was rooted running 4.4.2 and NC5. I foolishly accepted the update to NG6 and now I have problems. WiFi passwords aren't retained, and if I turn off WiFi it won't turn on again until I do a "Reset connections". But now, even the "Reset connections' option is missing. And I get a "Security Warning" about every 5 minutes.
I have installed Odin and tried to use it to re-flash an NC5. When I boot to the down-loader I see a "Write protection: Enabled" message. Odin establishes a connection with the phone, downloads the image, and reboots the phone, giving a message "Reset!". After this reset the phone runs for a few minutes, then crashes and reboots, over and over again. If I remove the battery and do a hard factory reset I can restore function, but I'm still at NG6. Is the "Write protection: Enabled" preventing the flash of NC5?
Here's what I want: 4.4.2 with NC5 rooted. (I can use TowelRoot to root NC5, but not NG6)
Help!
