to those who have passed, I got to fix it follows
going to mobile settings, mobile networks, network operators, when you locate the various networks, choose any other than yours to "try" to register in it, and while in the process, with the message "looking" or something, and the circle circling in occupied mode, restart the phone, or failing that, those not tengais enabled the advanced restart options development, power cycle, wait to put the pin one ratin, one or two minutes to go settled everything, and see if you have been taken notice
if so, solved for restarts next, I do step also doing something related to the mode change in a new installation, it is not solved with dirty reinstallation of ROM, this is the only means which I have worked for me too
