I don't know if I'm the only one, but after updating to the stock KK ROM (AndroidUser00110001 rooted), the phone loses the capability of sending-receiving SMS. No matter what app I use won't work, and all I get is the "Unfortunately, (App X) has stopped" error. I have to go back to Jelly Bean to get the SMS working again.
My D800 is unlocked, working in another carrier (Movistar)
Anybody else with the same problem?
