is there a way to update my phone without loosing root or changes made with root

hello i rooted my device with zv7 sprint ,and replaced the carrier files because i wanted to unlock it to use it with gsm carriers.

i would like to know if there is a way to update the phone without loosing the changes i realized ,i could loose the root access since i don't need it anymore.
also i received yesterday one pop up message that my phone was uicc unlocked (what does it means)??
