Not sure what happened, but after I flashed 21901 Color, my phone was no longer authenticated on VZW. I tried a *228 which said it was successful, but I still couldnt access the network. Flashing back to stock now to see if I can get healthy without a call to Big Red.
Edit : had to call VZW to get authenticated. Not sure what happened. I may stick with the B&W version for now since it looks like you may be questioning the provisioning for another issue already. Luckily I now have my AKey value, so I should be able to avoid this type of call to them in the future.
